[[pp. 58863-58912]] Medicare Program; Revisions to Payment Policies and Adjustments 
to the Relative Value Units Under the Physician Fee Schedule for 
Calendar Year 1999

[[Continued from page 58862]]

[[Page 58863]]

the applicable fee schedule amount will be the amount established for 
comparable services as specified by the Secretary. Therefore, we 
revised our policy so that the existing fee schedules for prosthetic 
and orthotic devices, durable medical equipment, and supplies, and 
drugs and biologicals apply when these services are furnished by a 
CORF. We believe that these fee schedules, together with the physician 
fee schedule, will encompass all CORF services other than nursing 
services. The physician fee schedule amount applicable to services 
furnished in a nonfacility setting will apply to the services furnished 
by the CORF since no separate payment will be made for facility costs.
    To establish a fee schedule amount for nursing services delivered 
within a CORF, we created a new HCPCS code, G0128. We have defined this 
code as direct face-to-face skilled nursing services delivered to a 
CORF patient as part of a rehabilitative plan of care. It is a timed 
code and can be billed for 10-minute intervals (when the initial 
interval is longer than 5 minutes). G0128 is to be used for services 
that are not included in the work or practice expense of another 
therapy or physician service. An example might be a nurse who spends 33 
minutes instructing a patient in the proper procedure of ``in and out'' 
urethral catheterization; in this situation, 3 units of G0128 would be 
billed. We are setting the RVUs for this code at 0.26, based upon half 
the value of the lowest level physician follow-up visit, HCPCS code 
99211, in the nonfacility setting. This results in a payment that is 
slightly more than the average wage reported by the Bureau of Labor 
Statistics (BLS) for registered nurses, inflated to reflect benefits 
and overhead (using the fringe benefit and expense factor used to 
establish the salary equivalency guideline).
    Comment: One commenter supported the use of the nonfacility 
physician fee schedule for therapy services performed in an SNF and 
CORF; however, clarification was requested as to whether the facility 
or the nonfacility physician fee schedule will be used for hospital 
outpatient departments.
    Response: The physician fee schedule payment amount applicable to 
outpatient rehabilitation services furnished by hospitals is the same 
as that for SNFs, CORFs, and other outpatient rehabilitation providers. 
That is, hospitals will be paid for these services under the 
nonfacility component of the physician fee schedule.
(5) Site-of-Service Differential
    We did not propose a site-of-service differential for providers of 
outpatient rehabilitation services as suggested by some of the 
providers prior to publication of our proposed rule. That is, we did 
not propose a payment amount greater or lesser than that provided by 
the physician fee schedule for some of the types of providers or sites 
at which outpatient rehabilitation services are furnished.
    As explained in our proposed rule, the law requires that these 
services be paid the amount determined ``under the fee schedule 
established under section 1848.'' Furthermore, we believe higher 
payment amounts for certain facilities, such as CORFs or rehabilitation 
agencies, would create payment incentives that favor one site or 
setting over another. We believe the statute establishes a ``level 
playing field'' for these services. We find no directive in the 
statutory language or legislative history that we recognize higher 
costs that some providers argue might be associated with furnishing 
services in a provider setting. To the extent that CORFs or 
rehabilitation facilities provide services to patients who need 
additional care, CORFs or rehabilitation facilities may bill for 
additional, medically necessary services. For these reasons, we are not 
revising our policy to allow for a site of service adjustment or higher 
payment amount for specific settings.
    Comment: One commenter believes the work RVU should be the same 
regardless of setting; however, the commenter contends that the 
practice expense component may differ among the settings. The commenter 
states that the impact of any unique regulatory requirements among 
settings on the cost of furnishing services should be determined.
    Response: As stated above, we find no statutory or legislative 
basis for recognizing a distinct payment differential that is site 
specific. Therefore, we are not revising our policy to allow for a 
payment differential among settings.
(6) Mandatory Assignment
    Section 1834(k)(6) of the Act, as added by BBA, establishes a 
restraint on billing for outpatient rehabilitation therapy services; 
that is, this provision requires that services paid under section 
1834(k) of the Act are subject to mandatory assignment under the same 
terms applicable to practitioners under section 1842(b)(18) of the Act. 
Therefore, we have revised our policy in accordance with this provision 
to require mandatory assignment for services provided under the 
outpatient rehabilitation prospective payment system by hospitals, 
SNFs, HHAs, rehabilitation agencies, public health agencies, clinics, 
and CORFs. The mandatory assignment provision does not apply to therapy 
services furnished by a physician or ``incident to'' a physician's 
service or to services furnished by a physical therapist in private 
practice or an occupational therapist in private practice. However, 
when these services are not furnished on an assignment-related basis, 
the limiting charge applies.
2. Uniform Procedure Codes for Outpatient Rehabilitation Services
    Section 4541(a)(2) of BBA added section 1834(k)(5) to the Act. This 
new statutory provision requires that claims submitted on or after 
April 1, 1998 for outpatient physical therapy services, including 
speech language pathology services and outpatient occupational therapy 
services, include a code under a uniform coding system that identifies 
the services furnished.
    The uniform coding requirement is needed to ensure proper payment 
under the physician fee schedule. Hospitals, SNFs, HHAs (for 
individuals who are not eligible for home health services), CORFs, and 
outpatient physical therapy providers must use HCPCS codes to report 
outpatient rehabilitation services when furnished to their outpatients. 
Hospitals and SNFs that provide outpatient rehabilitation services to 
their inpatients who are entitled to benefits under Part A but who have 
exhausted their benefits for inpatient services during a spell of 
illness or to their inpatients who are not entitled to benefits under 
Part A are also required to report HCPCS codes.
    In March, 1998, we issued Program Memorandum AB-98-8 which 
describes the coding for outpatient rehabilitation services and 
identifies certain HCPCS codes available for billing by CORFs that are 
not generally rehabilitation services, including vaccinations and 
nursing services. This memorandum also specifies how these codes will 
be reported on the UB-92. We assigned the various codes to revenue 
centers, that is, physical therapy, occupational therapy, and speech-
language pathology, for purposes of applying the financial limitation 
described below. Assigning codes to revenue centers was not intended to 
limit the scope of practice or range of procedures that could be 
furnished by therapists in a particular discipline. We recognize that 
many therapy services, for example, physical therapy

[[Page 58864]]

modalities or therapy procedures as described by HCPCS codes are 
commonly delivered by both physical and occupational therapists. Other 
services may be delivered by either occupational therapists or speech-
language pathologists.
    Therefore, in July 1998, we issued PM A-98-24 which in effect 
constituted a reissuance of PM A-98-8 in its entirety. PM A-98-24 was 
intended, in part, to clarify PM AB-98-8 regarding the reporting of 
HCPCS codes for outpatient rehabilitation and CORF services and to 
instruct fiscal intermediaries to eliminate edits installed to match 
revenue centers to outpatient rehabilitation HCPCS codes in order to 
cap therapy services. HCFA did not intend for such edits to be 
installed and employed. Thus, PM A-98-24 instructed fiscal 
intermediaries to eliminate the edits for services furnished on or 
after October 1, 1998. However, in response to industry concerns, on 
August 6, 1998, we issued a memorandum to all fiscal intermediaries 
advising them to remove immediately any coding edits imposed to match 
outpatient rehabilitation HCPCS codes to revenue codes.
    Comment: We received three comments regarding PM A-98-24 issued 
July 1998. The commenters stated that confusion remains regarding the 
effective date of the memorandum. Also, they urged that we instruct 
carriers to not deny claims based on the practitioners' failure to 
comply with coding requirements until there is a clarification 
regarding the manner in which the coding requirement is to be 
implemented. One commenter recommended that fiscal intermediaries be 
required to adhere to revised PM A-98-24, effective immediately. The 
commenter contended that claims wrongly denied based on PM AB-98-8 
should be promptly paid based on the claims originally submitted by 
providers.
    Response: We apologize for the confusion. As noted above, PM A-98-
24 carried an effective date of October 1, 1998 for fiscal 
intermediaries to remove any edits installed to match revenue center to 
HCPCS coding for outpatient rehabilitation services. As also stated 
above, on August 6, 1998 we issued a subsequent memorandum to all 
intermediaries advising them to remove the edits immediately. Providers 
and practitioners were encouraged to resubmit any claims that were 
incorrectly denied due to misinterpretation of our instructions for 
billing outpatient rehabilitation services using HCPCS codes.
    Comment: We received one comment recommending that the definition 
of outpatient rehabilitation services be expanded to include payment 
for low-vision training. The commenter stated that Medicare's failure 
to cover low-vision training places beneficiaries at risk for extreme 
out-of-pocket expenditures for transportation services, home-bound 
visits, and psychological counseling.
    Response: We have not accepted the commenter's recommendation. 
Outpatient rehabilitation services are clearly defined in the statute. 
Low-vision training is not specifically mentioned in the statute, and 
we find no statutory or legislative basis for including low-vision 
training in the definition of outpatient rehabilitation services. 
Therefore, we cannot arbitrarily expand our definition of outpatient 
rehabilitation to encompass low-vision training.
    Since the statute does not specifically identify low-vision 
training as a separate Medicare benefit and does not provide a basis 
for including it under the outpatient rehabilitation benefit, carriers 
have the discretion to cover these low-vision training services if they 
determine that they meet the statutory requirements applicable to 
covered services and are determined to be medically reasonable and 
necessary.
    Comment: A commenter recommends that CPT codes 92520, 94799, and 
psychiatric therapeutic codes after 90804 be added to the list of 
outpatient rehabilitation services. The commenter stated that code 
94799 is currently recognized by Blue Cross and Blue Shield of Florida. 
The commenter also stated that, in addition to code 90804, other 
psychiatric therapeutic codes should be added for assessments and 
community resource education, referral and advocacy, family 
conferences, and home assessments.
    Response: The commenter asked that we add code 92520, laryngeal 
function studies, to our list of outpatient therapy codes. Our data 
show that this code is almost entirely billed by otolaryngologists. Our 
standard for the inclusion of diagnostic tests as outpatient 
rehabilitation services is as follows:
    <bullet> If the primary purpose of a diagnostic test, at times 
performed by therapists, is to assess the appropriateness or 
effectiveness of outpatient therapy services or to guide additional 
treatment by a physical therapist, an occupational therapist or speech-
language pathologist, then the test is considered to be outpatient 
therapy or rehabilitation services; or
    <bullet> If the primary purpose of the diagnostic test is to 
provide information on decisions for future medical or surgical 
treatment or to assess the effect of previous medical or surgical 
treatment, then the diagnostic test is not considered to be an 
outpatient therapy or rehabilitation service.
    Because the purpose of code 92520 is not clear to us and because 
our data show that it is performed overwhelmingly by otolaryngologists, 
we suggest that providers and practitioners who believe it meets the 
above criteria as an outpatient rehabilitation service provide 
information to their Medicare contractors and the contractors can 
approve it if it meets the coverage criteria of being ``medically 
necessary.'' We advised our carriers and fiscal intermediaries in PM 
AB-98-24 that they may recognize codes other than those identified in 
our instruction as outpatient rehabilitation services to the extent 
that the codes represent services that are determined to be medically 
necessary and within the scope of practice of the practitioner or 
therapist billing the service.
    The commenter asked that code 94799, unlisted pulmonary services or 
procedures, be added to the list of outpatient rehabilitation services. 
Again, we suggest that practitioners and providers that wish to use 
this code to describe an outpatient rehabilitation service discuss with 
their Medicare contractor the specific services or procedures being 
provided when this code is used. Before this code can be used, the 
Medicare contractor needs to determine whether the services are 
``medically necessary.''
    The commenter also asked that we add other psychotherapy codes from 
the family of codes that includes 90804 that is on our list of 
outpatient rehabilitation services. Clinical psychologists and clinical 
social workers who deliver services in CORFs can bill any of the 
psychotherapy codes except for the ones that involve medical evaluation 
and management. These services are billed under Part B and are 
submitted to carriers on the HCFA form 1500. Therefore, these codes 
will not be added to our list of outpatient rehabilitation services.
    Comment: One commenter recommended adding to our final rule the 
statement contained in PM A-98-24 that denotes that other codes may be 
considered to represent outpatient rehabilitation services to the 
extent that the services are determined to be medically reasonable and 
necessary and can be billed as outpatient rehabilitation services.

[[Page 58865]]

    Response: Although we have included the statement in the text in 
the regulation, we will consider other codes to be outpatient 
rehabilitation codes under the terms we have stated.
    Comment: One commenter requested that we clarify in the final rule 
that Addendum F contains the codes for reporting outpatient 
rehabilitation services.
    Response: We appreciate the suggestion. It was inaccurately 
reported in the proposed rule that Addendum E contains a listing of 
outpatient rehabilitation therapy codes. It should have read that 
Addendum F contains such a listing. We have made the appropriate 
correction in this rule.
3. Financial Limitation
    a. Overview. Outpatient rehabilitation therapy services are subject 
to annual financial limitations or caps beginning January 1, 1999. (The 
amount of the current cap is $900.) There will be a $1,500 per-
beneficiary annual limitation or cap on incurred expenses for 
outpatient physical therapy services including outpatient speech-
language pathology services. A separate $1,500 per-beneficiary 
limitation will apply on incurred expenses for outpatient occupational 
therapy services. The annual limitation does not apply to services 
furnished directly or under arrangements by a hospital to an outpatient 
or to an inpatient who is not in a covered Part A stay. The limitation 
will apply to outpatient rehabilitation services furnished by a 
separately-certified hospital-based provider, such as a hospital-based 
SNF. The limitation also applies to outpatient rehabilitation services 
furnished by a physician or nonphysician practitioner, or incident to a 
physician's professional services or to a nonphysician practitioner's 
professional services.
    As stated above, there is a single $1,500 limitation for outpatient 
physical therapy services which includes outpatient speech-language 
pathology services. As amended, section 1833(g) of the Act applies a 
single $1,500 limitation to ``physical therapy services of the type 
described in section 1861(p).'' Section 1861(p) defines outpatient 
physical therapy services and includes speech-language pathology 
services within that definition.
    Outpatient rehabilitation services are subject to a 20-percent 
coinsurance amount. Under the outpatient prospective payment system, 
the beneficiary will be responsible for 20 percent of the applicable 
fee schedule amounts. The $1,500 limitation is on incurred expenses. If 
a beneficiary has already satisfied the Part B deductible, the maximum 
amount payable by the Medicare program is $1,200, that is, 80 percent 
of $1,500. Beginning January 1, 2002, the $1,500 annual limitations or 
caps will be increased by the percentage increase in the MEI.
    In addition to outpatient physical therapy services and outpatient 
occupational therapy services (other than those provided by a 
hospital), the limitation applies to physical therapy services 
(including speech-language pathology services) and occupational therapy 
services ``of such type which are furnished by a physician or as 
incident to a physician service.'' As discussed elsewhere in this 
document, Medicare covers under certain conditions services performed 
by nurse practitioners, clinical nurse specialists, and physician 
assistants that would be physicians' services if furnished by a 
physician. We are applying the financial limitation to therapy services 
furnished by these nonphysician practitioners because such therapy 
services are by definition the same type as are furnished by 
physicians. Similarly, we have revised our policy to apply the 
financial limitation to therapy services furnished incident to these 
nonphysician practitioner's services. We have included in Addendum D a 
listing of the specific services that are subject to the limitation 
when furnished by a physician or practitioner directly or incident to 
his or her services. Such outpatient rehabilitation services included 
in Addendum D furnished either directly or incident to the services of 
a physician or practitioner are always subject to the financial 
limitation. Other services such as casting, splinting, and strapping 
may be used in the treatment of conditions (for example, fractures or 
sprains) or as part of the postsurgical treatment or medical treatment 
when no other rehabilitation services are delivered. If the services 
are delivered by a physical or occupational therapist, speech-language 
pathologist, therapy assistant or therapy aide, are part of a 
rehabilitation plan of care, or involve services included in the 
aforementioned Addendum D, then the services are subject to the cap. 
These outpatient rehabilitation services are delineated in Addendum E 
and must be identified with a discipline-specific modifier. Addendum F 
contains a listing of commonly-utilized outpatient rehabilitation 
therapy codes. Other codes may be considered for payment as outpatient 
rehabilitation services to the extent that the services are determined 
to be medically reasonable and necessary and those that can be 
performed within the scope of practice of the therapist, physician, or 
nonphysician practitioner billing the code. Payment for certain HCPCS 
codes will be made on a basis other than the physician fee schedule in 
hospital outpatient departments. Other HCPCS codes represent CORF 
services. Further, PM AB-98-63 dated October 1998 provides additional 
program instructions regarding the use of HCPCS codes for outpatient 
rehabilitation therapy services.
    With regard to ``incident to'' services, we note that section 
4541(b) of BBA amended section 1862(a) of the Act to require that 
outpatient physical therapy services (including speech-language 
pathology services) and outpatient occupational therapy services 
furnished ``incident to'' a physician's professional services meet the 
standards and conditions (other than any licensing requirement 
specified by the Secretary) that apply to therapy services furnished by 
a therapist. This provision was effective January 1, 1998 and was 
implemented through program instructions.
    The financial limitations apply only to items and services 
furnished by nonhospital providers and therapists under the outpatient 
physical therapy (including speech-language pathology) and the 
outpatient occupational therapy benefit (section 1861(s)(2)(D) of the 
Act) and therapy services furnished by physicians and nonphysician 
practitioners or incident to their services. The limitations do not 
apply to diagnostic tests covered under section 1861(s)(3) of the Act 
or to items furnished or covered under the durable medical equipment 
benefit.
    Comment: Some commenters urged us to repeal the limitation.
    Response: We have no authority to repeal the annual financial 
limitation as set forth in BBA. An annual per beneficiary limit of 
$1,500 will apply to all outpatient physical therapy services 
(including speech-language pathology services). A separate $1,500 limit 
will also apply to all occupational therapy services. As noted above 
the annual limitations do not apply to services furnished directly or 
under arrangements by a hospital to an outpatient or to an inpatient 
who is not in a covered Part A stay. This limitation applies to 
expenses incurred on or after January 1, 1999.
    Comment: Several commenters want us to delay implementing the 
financial limitation while others asked that, if we proceed with 
implementation, we clarify how we would implement it. We received one 
comment suggesting that we delay the implementation of the annual 
limitation until we develop a

[[Page 58866]]

system of tracking the aggregate amount of speech-language pathology 
expenses incurred by a beneficiary.
    Response: As previously stated, because of our efforts to become 
Y2K compliant, with the exception of qualified therapists in 
independent practice, we are not able to make the appropriate systems 
changes to fully implement the caps on a per-beneficiary basis at this 
time. Instead, we will use a transitional measure, whereby providers 
and practitioners (those not currently subject to the caps, for 
example, physicians and nonphysician practitioners) will be held 
accountable for tracking incurred expenses for each beneficiary to 
ensure they do not bill Medicare for beneficiaries that have met the 
annual $1,500 limitation at their facility for each separate 
limitation. This means that SNFs will be directly responsible for the 
billing of all outpatient rehabilitation services and the tracking of 
incurred expenses of those services when furnished to SNF residents not 
in a covered Part A stay and SNF nonresidents receiving outpatient 
rehabilitation services from the SNF.
    However, the provider and the practitioner may submit bills to 
Medicare for the sole purpose of receiving no-pay notices to bill 
Medicaid or other insurers.
    It is noted that the current annual per beneficiary financial 
limitation applied to outpatient physical therapy services including 
speech-language pathology services furnished by PTIPs is increased from 
$900 to $1,500 effective January 1, 1999 for PTPPs. In addition, the 
current annual per beneficiary financial limitation applied to 
outpatient occupational therapy services is increased from $900 to 
$1,500 effective January 1, 1999 for OTPPs. As cited, for these 
qualified therapists only, the financial limitations continue to be 
applied on an annual per beneficiary basis rather than on a per 
provider basis.
    Comment: Many commenters believed there should be three separate 
annual financial limitations, that is, one each for physical therapy, 
occupational therapy, and speech-language therapy services. They argue 
that the Congress never intended to include speech-language pathology 
services within the physical therapy cap because speech therapists have 
never been defined as independent therapists and were never subject to 
the current $900 cap.
    Response: As stated above, section 1861(p) of the Act defines the 
term outpatient physical therapy services to include speech-language 
pathology services. The language in BBA specifically makes provision 
for physical therapy services and occupational therapy services in 
applying the annual financial limitation and does not separately 
mention speech-language pathology services. It is our position that BBA 
does not include a separate cap for speech-language pathology services, 
and that there are only two financial limitations (OT and PT that 
includes speech-language therapy services).
    Comment: Two commenters oppose the imposition of the $1,500 cap 
because it is not sufficient to cover the cost of physical therapy for 
many common diagnoses or cost of care for typical rehabilitation cases. 
One of the commenters noted that MedPAC found in its June 1998 report 
to Congress that one third of the patients receiving outpatient 
rehabilitation services from rehabilitation agencies and CORFs exceeded 
either the combined $1,500 cap on outpatient physical therapy and 
speech-language pathology or the $1,500 cap on outpatient occupational 
therapy.
    Response: The commenter is correct in stating that the MedPAC's 
study of a 5-percent sample of Medicare outpatient rehabilitation 
claims for 1996 did find that about one-third of all patients receiving 
outpatient rehabilitation services from rehabilitation agencies and 
CORFs exceeded the $1,500 caps. However, the study noted that because 
most Medicare beneficiaries received the services in hospital 
outpatient departments in 1996, the percent of all patients impacted by 
the $1,500 caps is considerably less, that is, only 10 percent of all 
outpatient physical and speech therapy patients receiving services in 
hospital outpatient departments, rehabilitation agencies and CORFs and 
only 2 percent of all occupational therapy patients in those three 
settings.
    We plan to carefully study this issue. As discussed elsewhere in 
this document, BBA requires that we submit a report to the Congress by 
January 1, 2001 that recommends viable options for replacing the 
current dollar caps that take into account patient diagnosis and prior 
use of services.
    Comment: One commenter stated that the limitation should apply only 
to therapy services furnished by physical therapists and occupational 
therapists, and not to therapy services furnished by physicians. 
Another commenter contends that the cap applies solely to therapists 
and physicians furnishing outpatient rehabilitation services under a 
plan of care. Neither commenter believes that nonphysician 
practitioners should be allowed to perform therapy services. These 
commenters argue that only physical therapists or services provided 
under the supervision of a physical therapist should be reimbursed by 
Medicare. The commenters maintain that the definition of physical 
therapists as referenced in Sec. 485.705(b) and the coverage guidelines 
specified in section 2210.B of the MCM and 3101.8B of the MIM are not 
met if the services are provided by persons other than physical 
therapists. In addition, the statute does not extend the cap to 
services furnished by practitioners other than OTIPs and PTIPs.
    Response: Section 4541 of BBA provides for a prospective payment 
for outpatient rehabilitation services. The operative word in the 
statute is ``services''. Reference is made both to the payment for 
outpatient therapy services and comprehensive outpatient rehabilitation 
services on the basis of the physician fee schedule and to the 
financial limitation for all rehabilitation services. The fee schedule 
is applied to outpatient therapy or rehabilitation services without 
regard to the practitioner who furnishes the service. Physical and 
occupational therapy services furnished by physicians and certain other 
recognized practitioners are payable under the physician fee schedule. 
A nonphysician practitioner who provides services that would be 
physicians' services if furnished by a physician under a specific 
enumerated benefit in the statute would be considered as the physician 
treating the beneficiary. Thus, a nonphysician practitioner would be 
considered as the physician treating the beneficiary when he or she 
furnishes outpatient physical therapy and occupational therapy 
services. Nonphysician practitioners who meet this definition are 
physician assistants (section 1861(s)(2)(K)(I) of the Act); and nurse 
practitioners and clinical nurse specialists (sections 
1861(s)(2)(K)(ii) and 1861(s)(2)(K)(iii) of the Act), operating within 
the scope of their State licenses.
    B. Use of Modifiers to Track the Financial Limitation. We have 
established three discipline-specific modifiers for use in tracking the 
financial limitation or cap. They are listed below.

GN  Services delivered personally by a speech-language pathologist or 
under an outpatient speech-language pathology plan of care;
GO  Service delivered personally by an occupational therapist or under 
an outpatient occupational therapy plan of care; or
GP  Service delivered personally by a physical therapist or under an 
outpatient physical therapy plan of care.


[[Page 58867]]


    Reporting of these modifiers will also assist us in gathering data 
on who is providing the services, and the frequency and duration of the 
services. Many of the services, for example, physical modalities or 
therapeutic procedures as described by HCPCS codes, are commonly 
delivered by both physical and occupational therapists. Other services 
may be delivered by either occupational therapists or speech-language 
pathologists. For these services, we expect the claim to include a 
modifier that describes the type of therapist who delivered the 
service; if the service was not delivered by a therapist, then the type 
of therapy plan of care under which the service is delivered would be 
specified. If the type of therapy is not listed in the modifier field, 
the claim would be rejected and sent to the provider for resubmission.
    Comment: We received one comment that supports our proposal to use 
modifiers that will be discipline-specific to identify whether a plan 
of care is for physical therapy or occupational therapy. However, the 
commenter also favors the addition of modifiers that will allow for the 
identification of physician and nonphysician services that are provided 
under a plan of care. Claims from physicians and nonphysicians with a 
modifier would be subject to one of the caps, while claims without a 
modifier would not be subject to any cap. Another commenter stated that 
the proposed policy to reject a claim and send it to the provider for 
resubmission if the type of therapy is not listed in the modifier field 
is inappropriate and should not be adopted. The commenter contends that 
there are legitimate cases in which the codes in Addendum D will be 
reported but should not be applied against the caps, for example, if 
the services are furnished by a nonphysician practitioner or a 
physician but they are not provided under a therapy plan of care. This 
contention is also shared by another commenter who strongly opposed our 
proposal to apply services against the caps for occupational therapy 
and physical therapy including speech-language pathology services based 
strictly on an arbitrary reporting of certain CPT codes. The 
presumption with this approach is that therapy services are furnished 
whenever codes listed in Addendum D are reported
    Response: At this time, we have decided to only use the discipline-
specific modifiers listed in the response above. These modifiers will 
differentiate between either the type of therapist (physical therapist, 
occupational therapist, speech-language pathologist) personally 
providing the service or the discipline plan of care (physical, 
occupational, and speech-language pathology). For example, if modifier 
GP is used, the physical therapist must deliver personally the service 
or the service must be delivered under a physical therapy plan of care. 
Therefore, in addition to the personal provision of the therapy service 
by the physical therapist, a physician or nonphysician practitioner can 
also furnish the physical therapy service. We believe that additional 
modifiers are not needed to delineate services provided by physicians 
and nonphysician practitioners under a therapy plan of care; however, 
we believe that the commenter's statement is valid regarding the 
possible use of codes listed in Addendum D for other than therapy 
purposes, that is, not under a therapy plan of care. We are exploring 
the use of an additional modifier to indicate that the service denoted 
by the code was not provided under a therapy plan of care. By the time 
that the financial limitation or cap is fully implemented, we expect to 
have established the additional modifier. Until that modifier is in 
place, claims without a discipline-specific modifier will be returned 
for resubmission.
    Comment: A commenter stated that the cap will be difficult to track 
administratively and recommended that there be a clearer delineation of 
when services will be subject to the limit and what the controlling 
factors will be (including the type of professional delivering the 
service, whether there is a rehabilitation plan of care, and the nature 
of the service), a listing or examples of services and the 
circumstances under which they would not be included under the cap.
    Response: The commenter's request for clarification is based on a 
full implementation of the financial limitation or cap. Because of Y2K 
issues, the financial limitation or cap will not be fully implemented 
as mandated by statute effective January 1, 1999. Therefore, it is our 
intention to carefully review, consider, and address the commenter's 
concerns as we move from the transitional implementation of the cap on 
a per-provider basis to the full implementation of the cap on an annual 
per-beneficiary basis.
    Comment: One commenter stated that the mechanics of implementing 
the cap should be clarified. The commenter said that there are serious 
concerns regarding the calculation of the cap, time of billing, and 
timing of processing payments that would be fed into the database. The 
commenter is concerned about the effect of medical review, for example, 
whether payment will be reserved when a claim is filed in a timely 
manner, subjected to medical review, denied, and successfully appealed, 
and the claim was originally filed well before the cap is met. Several 
commenters were of the opinion that it is administratively difficult 
for all parties (beneficiaries, providers, and contractors) to track 
the cap even with the use of the modifiers. They want us to address 
specific issues regarding tracking and the use of modifiers before 
implementation of the cap, and to also notify beneficiaries regarding 
the tracking procedure. These specific issues include a clear 
delineation of when services are subject to the limit, what the 
controlling factors will be (including the type of professional 
delivering the service, whether there is a rehabilitation plan of care, 
and the nature of the service), a listing or examples of the services 
and the circumstances under which they would be excluded from the cap.
    Response: These are issues that will be addressed prior to the full 
implementation of the financial limitation or cap. Because there is the 
distinct possibility that systems requirements will change before such 
full implementation, it does not seem prudent at this time to detail 
the mechanics of the future implementation of the cap. However, it is 
our current thinking that these concerns will be discussed and 
clarified in companion program instructions issued to the Medicare 
carriers and fiscal intermediaries.
    Comment: A commenter stated that there should be a timely, readily 
accessible means (such as a query system) for beneficiaries and 
providers to ascertain the status of the beneficiary's outpatient 
therapy benefits.
    Response: This question relates to the full implementation of the 
financial limitation or cap on an annual per-beneficiary basis. We are 
exploring mechanisms by which both the beneficiary and the provider can 
be informed in a timely and accurate manner, the amounts that have been 
expended by the beneficiary for outpatient physical therapy services 
including speech language pathology services and for outpatient 
occupational therapy services. These methods will be discussed in any 
program memorandum or other program instruction that we determine will 
be the vehicle for the conveyance of the beneficiary cap status 
information.
    C. Treatment of Services Exceeding the Financial Limitation. As 
required by section 1833(g) of the Act, as amended by section 4541 of 
BBA, we revised our

[[Page 58868]]

policy to establish two annual per-beneficiary limits of $1,500. There 
will be (1) an annual per-beneficiary limit for all outpatient physical 
therapy services excluding hospital outpatient therapy services 
furnished to an outpatient or an inpatient who is not in a covered Part 
A stay and, (2) an annual per beneficiary limit for all outpatient 
occupational therapy services excluding hospital outpatient therapy 
services furnished to an outpatient or an inpatient who is not in a 
covered Part A stay. As stated previously, outpatient physical therapy 
services include speech-language pathology services. A provider of 
outpatient rehabilitation services with a provider agreement under 
section 1866 of the Act, as well as physicians, PTIPs and OTIPs, will 
be allowed to collect payment from a beneficiary for therapy services 
after the $1,500 limit is reached. This is consistent with current 
policy allowing PTIPs and OTIPs to collect payment from a beneficiary 
for therapy services in excess of the current $900 limit.

Required Congressional Report on Financial Limitation

    We note that a report to the Congress is due from the Secretary no 
later than January 1, 2001. This report must include recommendations on 
the establishment of a revised coverage policy of outpatient physical 
therapy services, including speech-language pathology services and 
outpatient occupational therapy services. The revised policy must be 
based on a classification of individuals by diagnosis category and 
prior use of services in both inpatient and outpatient settings. The 
report should include recommendations on how such durational limits by 
diagnostic category could be implemented in a budget-neutral manner.
    Comment: It was recommended by a commenter for the report to the 
Congress that, in addition to basing a revised policy on classification 
by diagnosis category and prior use of services, an individual's 
functional status should be a component of any system that purports to 
address a patient's need for rehabilitation.
    Response: As we develop the report to the Congress, we will 
consider the feasibility of the recommendation.
4. Qualified Therapists
    Section 1861(p) includes services furnished an individual by a 
physical therapist who meets licensing and other standards prescribed 
by the Secretary if the services meet the conditions relating to health 
and safety the Secretary finds necessary. The services must be 
furnished in the therapist's office or the individual's home. By 
regulation, we have defined therapists meeting the conditions for 
coverage of services under this provision as physical therapists in 
independent practice. The conditions for coverage are set forth in part 
486, subpart D (Conditions for coverage: Outpatient Physical Therapy 
Services Furnished by Physical Therapists in Independent Practice) and 
require that the services be provided by a therapist in independent 
practice under Sec. 410.60. Under Sec. 410.60, a therapist in 
independent practice is one who:
    <bullet> Engages in the practice of therapy on a regular basis.
    <bullet> Furnishes services on his or her own responsibility 
without the administrative and professional control of an employer.
    <bullet> Maintains at his or her own expense office space and 
equipment.
    <bullet> Furnishes services only in the office or patient's home.
    <bullet> Treats individuals who are his or her own patients and 
collects fees or other compensation for the services.
    Under Sec. 486.151 (Conditions for coverage: Supervision), all 
therapy services must be furnished under the direct supervision of a 
qualified therapist in independent practice. In other words, the 
therapist in independent practice must be on the premises whenever 
services are provided to Medicare beneficiaries, including services 
provided by a licensed physical therapist. This long-standing 
requirement has been controversial with therapists in independent 
practice. For example, a therapist in independent practice cannot have 
more than one office open for services at the same time since he or she 
could not be on both premises at once.
    We are revising our policy to replace the existing ``Conditions for 
Coverage: Outpatient Physical Therapy Services Furnished by Physical 
Therapists in Independent Practice'' (part 486, subpart D), which 
requires survey and certification, with a simplified criteria for 
physical therapists in private practice that would use a carrier 
enrollment process. The impetus for this change comes from 
congressional statements associated with the fiscal year 1997 
appropriations process. Statements in both the House and Senate 
committee reports accompanying HCFA's fiscal year 1997 appropriations 
addressed the issue of requiring that the certified physical or 
occupational therapist in independent practice directly supervise all 
services performed by his or her employees, even if those employees are 
fully-licensed therapists. The House committee report urged that we 
modify the regulations so that the certified therapist need not be on 
premises to supervise other licensed therapists. The Senate urged us to 
review this concern and recommend regulatory or instructional changes.
    We are redefining those therapists who are qualified under section 
1861(p) of the Act. That is, we would discontinue the focus of the 
regulation on their ``independent'' status (which is not statutory) and 
recognize therapists in private practice who are employed by others 
and, therefore, do not meet our current ``independent'' criteria. This 
would be consistent with health and safety concerns and would conform 
to normal private sector practice standards. The following new 
requirements replace the current ones for qualified therapists:
    <bullet> The term ``independent'' is dropped and the benefit would 
be for an individual physical therapist or occupational therapist in 
private practice.
    Private practice includes an ``individual'' whose practice is in an 
unincorporated solo practice, unincorporated partnership, or 
unincorporated group practice. Private practice also includes an 
``individual'' who is practicing therapy as an employee of one of the 
above or of a professional corporation or other incorporated therapy 
practice. However, private practice does not include individuals when 
they are working as employees of a provider. A provider as defined in 
Sec. 400.202 includes a hospital, CAH, SNF, HHA, hospice, CORF, CMHC, 
or an organization qualified under part 485, subpart H (Conditions of 
Participation for Clinics, Rehabilitation Agencies, and Public Health 
Agencies as Providers of Outpatient Physical Therapy and Speech-
Language Pathology Services), as a clinic, rehabilitation agency, or 
public health agency.
    <bullet> In implementing the statutory requirement that services be 
furnished to an individual in the therapist's office, or in the 
individual's home, ``in his office'' is defined as the location(s) 
where the practice is operated, in the State(s) where the therapist 
(and practice, if applicable) is legally authorized to furnish 
services, during the hours that the therapist engages in practice at 
that location.
    A therapist in private practice must maintain a private office, if 
services always are furnished in patients' homes. However, if services 
are furnished in private practice office space, that space would have 
to be owned, leased, or

[[Page 58869]]

rented by the practice and used for the exclusive purpose of operating 
the practice. For example, because of the statutory restriction on the 
site of services, a therapist in private practice cannot furnish 
covered services in an SNF. Therefore, if a therapist wished to locate 
his or her private office on site at a nursing facility, special care 
would need to be taken. The private office space could not be part of 
the Medicare-participating SNF's space, and the therapist's services 
could be furnished only within that private office space. Neither the 
therapist nor any assistants or aides who help furnish services could 
be employed by the SNF during the same hours that they are working in 
the private practice. Another example where special attention would be 
needed is space that generally serves other purposes and is only used 
by a therapy practice during limited hours. For example, a therapist in 
private practice may furnish aquatic therapy in a community center pool 
on Wednesday mornings. The practice would have to rent or lease the 
pool for those hours, and the use of the pool during that time would 
have to be restricted to the therapist's patients, in order to 
recognize the pool as part of the therapist's own private office during 
those hours.
    In describing other services that are specifically limited to the 
patient's home, the statute uses qualifying language. For example, the 
durable medical equipment definition in section 1861(n) of the Act 
refers to a patient's home as ``including an institution used as his 
home other than an institution that meets the requirements of 
subsection (e)(1) of this section or section 1819(a)(1).'' This 
definition of home is codified under our regulations at Sec. 410.38(b). 
The same definition always has been used in the Medicare Carriers 
Manual for purposes of covering therapists' services in a patient's 
home. We are continuing the current practice and are adopting the 
definition formally in this regulation.
    <bullet> Assistants and aides have to be personally supervised by 
the therapist and employed directly by the therapist, by the 
partnership or group to which the therapist belongs, or by the same 
private practice that employs the therapist. Personal supervision 
requires that the therapist be in the room during the performance of 
the service. Levels of supervision are defined in Sec. 410.32 of our 
regulations.
    <bullet> The therapist must be licensed or otherwise legally 
authorized to engage in private practice. We understand that all States 
license or certify physical therapists, so no alternative personnel 
qualifications need to be specified.
    <bullet> Each therapist enrolls ``as an individual'' with the 
carrier.
    There would be no survey and no certification by HCFA. The Medicare 
carrier would verify that the qualifications proposed in 
Secs. 410.59(c)(1) or 410.60(c)(1) of our regulations are met. All 
applicants for new enrollment would become subject to these new rules 
and procedures upon the effective date of the final rule. For 
transition purposes, we intend that independent therapists who are 
certified and enrolled at that time would be ``grandfathered'' 
temporarily and would become subject to the new enrollment rules and 
procedures at the time of their next regular periodic reenrollment.
    These changes would address the concern that current rules require 
each independent therapist to personally supervise services performed 
by any other licensed therapists that he or she employs. Under our 
proposal, each individual therapist in a practice could qualify to 
separately enroll, and enrolled therapists would not be required for 
purposes of Medicare to be supervised by their employer. These changes 
also address the concern that current rules prohibit an independent 
therapist from being employed by any entity. Under our proposal, a 
variety of employment situations would be permitted.
    These new requirements are established in a revised Sec. 410.60(c) 
for physical therapists. To date, the statutory requirements for 
coverage of outpatient occupational therapy services have not been 
codified. We are codifying these requirements by establishing a new 
Sec. 410.59 for outpatient occupational therapy services. The 
regulations section for outpatient occupational therapy parallels the 
Sec. 410.60 requirements for outpatient physical therapy, as revised in 
this final rule. We are also making conforming changes in Sec. 410.61 
to include occupational therapy.
    Therapists in private practice do not participate in the Medicare 
program in the same way that ``providers of services'' do. Though they 
must be approved as meeting certain requirements, unlike ``providers of 
services,'' they do not execute a formal provider agreement with the 
Secretary as described in 42 CFR part 489 (Provider Agreements and 
Supplier Approval). Like physicians, they do have the option of 
accepting a beneficiary's assignment of his or her claim for Medicare 
Part B benefits and of becoming a Medicare-participating supplier that 
agrees to accept assignment in all cases.
    Comment: One commenter strongly supports the carrier enrollment 
process for physical therapists instead of the existing conditions of 
coverage. However, the commenter wanted operational issues addressed 
such as a specification that payments will be made under the practice 
or corporation's tax ID number for services furnished by physical 
therapists in private practice who are employees of other practices or 
corporations. This is the same payment system used by a physician group 
practice, and the treating therapist's Medicare number or license 
number would be included on the bill. In addition, the commenter urged 
that the same process be used for the carrier enrollment process as for 
the current physician enrollment. Another commenter supported the 
changes for OTPPs; however, assuming that payment is made to the 
individual, the commenter inquired as to whether group numbers would be 
assigned so that payment could be issued to the group under the tax 
identification number of the business entity.
    Response: We will use the same enrollment and billing process as is 
currently used for individual physicians and physician group practices. 
This process is delineated at section 1030.7 of the Medicare Carriers 
Manual, HCFA Pub. 14-Part 4. We note that payment is not made on the 
basis of the corporate or group practice tax identification number. 
This number is just one of the data elements that can be related to the 
Medicare individual and/or group billing number.
    Comment: A commenter recommended that direct supervision of 
assistants and aides be required instead of personal supervision. The 
commenter provided that direct supervision would be consistent with 
state laws, the supervision requirements for nonphysician personnel 
performing services in a physician's office, and with the supervision 
requirements for aides and assistants of PTIPs.
    Another commenter agreed that personal supervision over therapy 
aides by a qualified occupational therapist or qualified occupational 
therapy assistant is appropriate. However, the commenter strongly 
disagreed with the proposal to require personal supervision over 
occupational therapy assistants and instead urged the adoption of a 
policy for practicing occupational therapists whereby occupational 
therapy assistants can perform covered services under the general 
supervision (that is, initial direction and periodic inspection) of a 
qualified occupational therapist. In

[[Page 58870]]

addition, the commenter thought the policy should state that either a 
qualified occupational therapist or a qualified occupational therapy 
assistant must provide personal supervision when therapy aides are used 
to furnish services.
    A commenter stated that qualified occupational therapists who are 
not Part B suppliers, but who are employed by a therapist who is 
enrolled as a Part B supplier, should not be subject to the personal 
supervision requirement. In addition, it was suggested that the 
proposed language at Sec. 410.59(c)(2) regarding supervision of 
occupational therapy services should be revised as follows:
    ``Occupational therapy services are performed by, or under the 
general supervision of, the occupational therapist in private practice. 
Services provided by therapy aides must be performed under the personal 
supervision of an occupational therapist or occupational therapy 
assistant. All services not performed personally by the therapist in 
private practice must be performed by employees of the practice, under 
the applicable level of supervision by the therapist, and included in 
the fee for the therapist's services.''
    Response: Statements contained in the House and Senate committee 
reports accompanying the 1997 appropriations recommended modifications 
in our supervision requirements for qualified therapists. As stated, 
the House committee report urged a regulatory change in the requirement 
that certified therapists be on the premises to supervise other 
licensed therapists. We were also urged by the Senate to review this 
concern and recommend regulatory or instructional changes. We have 
addressed the concern expressed in the House and Senate 1997 
appropriations committee reports and will allow certified therapists to 
be off the premises when other licensed therapists are present. 
However, we do not believe that we have the authority to modify the 
supervision requirements for therapy (physical, occupational or speech-
language pathology) assistants and aides. Therefore, we are maintaining 
our current requirement that therapy assistants and aides have to be 
personally supervised by the therapist and employed directly by the 
therapist, by the partnership or group to which the therapist belongs. 
In accordance with the aforementioned policy, there is no change in the 
proposed language found at Sec. 410.59(c)(2).
    Comment: We received one comment on our proposed qualifications for 
occupational therapists. One organization recommends that we require 
evidence of successful completion of a national certification 
examination recognized by the regulatory authority in the State of 
practice. Reasons given for the addition of this requirement are that 
practice varies by jurisdiction and unsuccessful exam candidates often 
move from State to State obtaining temporary licenses in spite of 
repeatedly failing qualifying exams. The commenter adds that the 
particular test they recommend is required in every jurisdiction.
    Response: We believe that this recommendation has merit. However, 
we believe that it requires further study and discussion to assess its 
impact before we can consider it for adoption. Therefore, we believe it 
would be more appropriate to consider this recommendation as a proposal 
for a subsequent publication rather to accept it for adoption in this 
final rule.
    Comment: One commenter supports our proposed set of changes 
addressing independent practicing occupational therapist services, but 
adds that as Medicare moves to embrace market based competition, the 
focus should be on the outcomes delivered rather than the input 
credentialing. There should be a commitment to move beyond burdensome 
input criteria that add costs and restrict competition. The commenter 
suggests that, as part of that initiative, we establish a meaningful 
time horizon for moving to outcomes-based performance measures.
    Response: This is a welcomed recommendation. In recent years, when 
revising our conditions of participation for various entities, we have 
emphasized outcomes-based measures. However, this is an area that 
requires further study in order to apply this concept to our conditions 
for occupational therapists practice.
    Comment: One commenter stated that verification should be provided 
in the final rule that section 1861(p) of the Act requires a physician 
to have services furnished by a licensed physical therapist or under 
the supervision of such a therapist when billing for physical therapist 
services incident to the physician's professional services.
    Response: Section 1861(p) of the Act does not set forth the 
requirements as specified by the commenter. As previously stated, 
section 4541(b) of the BBA 1997 amended section 1862(a) of the Act to 
require that outpatient physical therapy services (including speech-
language pathology services) and occupational therapy services 
furnished ``incident to'' a physician's professional services meet the 
standards and conditions (other than any licensing requirement 
specified by the Secretary) that apply to therapy services furnished by 
a therapist. In May 1998, we issued Transmittal No. 1606 of the 
Medicare Carriers Manual, Part 3--Claims Process which implemented this 
provision that was effective January 1, 1998. Section 2218(A) of the 
Medicare Carriers Manual requires that physical therapy services 
provided by a physician or by an incident-to employee of the physician 
in the physician's office or the beneficiary's home must be provided 
by, or under the direct supervision of, a physician (a doctor of 
medicine or osteopathy) who is legally authorized to practice physical 
therapy services by the State in which he or she performs such function 
or action.
5. Plan of Treatment
    We are proposing to revise Secs. 410.61(e), 424.24(c)(4)(i), and 
485.711(b), which concern the plan of treatment review requirements for 
outpatient rehabilitation therapy services. Section 1861(p) of the Act 
defines these therapy services, in part, as services furnished to an 
individual who is under the care of a physician and for whom a plan, 
prescribing the type, amount, and duration of therapy services that are 
to be furnished, has been established by a physician or a qualified 
therapist and is periodically reviewed by a physician.
    Currently, providers that furnish outpatient rehabilitation therapy 
services are required to have a physician review the plan of treatment 
and recertify the need for care at least every 30 days. We proposed 
revising our policy to allow the physician to review and recertify the 
required plan of treatment within the first 62 days and at least every 
31 days after the first review and recertification. The current 
requirement for the review of a plan of treatment for patients of 
physical therapists in independent practice is similar in that the 
physician must review the plan at least every 30 days. We proposed 
changing this review requirement and requiring that the physician 
review and recertify the plan of treatment within the first 62 days and 
at least every 31 days thereafter.
    We recommended these changes because it was our understanding that 
an initial 2-month (62 day) review is consistent with the usual therapy 
course of treatment. It is also consistent with our current therapy 
requirements in the home health setting. These changes were intended to 
reduce the burden on providers, patients, and physicians by eliminating 
the current requirement for an initial review within the first 30 days. 
After the first 62 days, we believed

[[Page 58871]]

that patients receiving outpatient rehabilitation services are likely 
to show significant progress that warrants subsequent reviews every 31 
days. Changes in the patient's level of function and need for continued 
therapy can be expected to occur more frequently after the first 2 
months of therapy. We believe this subsequent review schedule will help 
control potential over-utilization that results in excessive therapy to 
some Medicare patients.
    Under our proposed policy, the therapists would be required to 
immediately notify the physician of any changes in the patient's 
condition, and physicians retain the ability to review the care at 
closer intervals if necessary.
    Comment: We received comments from six outpatient rehabilitation 
associations supporting our proposal and two comments from orthopedic 
surgical associations strongly opposing it. The opposing orthopedic 
associations informed us that 62 days is not the usual course of 
treatment. They argued that every patient's need for therapy is unique 
depending on the condition. While 62 days may be appropriate for some 
back injuries, they contend it would be inappropriate for a hand, foot, 
or shoulder injury. Therapy is appropriate as long as the patient 
continues to make progress and should be discontinued when the 
patient's condition has plateaued and no further progress is being 
made. They stated this can best be determined by the referring 
physician periodically evaluating the patient's progress and recovery. 
They believe the current 30-day requirement is appropriate and should 
be maintained.
    Response: After careful review of the comments received and study 
of the issue by our medical staff, we are retaining our current 30-day 
requirement and rescind our proposal. As indicated above, our intent, 
in part, was to establish consistency with the initial review period 
for HHA therapy services. However, subsequent to our proposal we 
further learned that HHA patients may not receive the same level of 
intensity of therapy services as patients receiving them under the 
outpatient rehabilitation benefit. Our medical staff believes that 
patients in the latter group are seen more often by their therapists 
than are HHA patients. Therefore, the rate of progression between the 
two patient groups may be different and warrant a 30-day rather 62-day 
initial plan of treatment review for beneficiaries receiving outpatient 
rehabilitation services.
    Comment: We received several comments to allow nonphysician 
practioners such as nurse practitioners, physician assistants, and 
clinical nurse specialist to certify the therapy plan of care.
    Response: Because we allow nonphysician practioners, that is, nurse 
practitioners, clinical nurse specialists, and physician assistants to 
prescribe medicine, we have also decided that nonphysician practioners 
who have knowledge of the therapy case may certify therapy plans of 
treatment.
    Result of the evaluation of comments: We are adopting our proposal 
to pay all outpatient rehabilitation services and CORF services under 
the physician fee schedule. We are delaying full implementation of the 
financial limitations on outpatient rehabilitation services furnished 
by nonhospital entities due to our Y2K efforts until after January 1, 
2000. We are not adopting a site-of-service differential for outpatient 
rehabilitation providers as recommended by commenters. Regarding 
proposed qualifications for therapists, we are adopting them as 
proposed and are not accepting the recommendation that we require 
occupational therapists to provide evidence of successful completion of 
a national certification examination. We anticipate that this issue 
will be further studied and discussed in a subsequent rule. We are 
withdrawing our proposal to extend from 30 days to 60 days the time 
required for physician recertification of the plan of treatment.

D. Payment for Services of Certain Nonphysician Practitioners and 
Services Furnished Incident to Their Professional Services

    Nonphysician practitioners' services have been covered by Medicare 
since the inception of the program; originally the law did not provide 
for separate payments for these services. Coverage and payment of 
nonphysicians' services was primarily within the context of section 
1861(s)(2)(A) of the Act as implemented by section 2050 of the Medicare 
Carriers Manual, for the payment of services incident to a physician's 
professional services. In recent years, the Congress has expanded 
Medicare coverage of nonphysician practitioners' services in certain 
settings to improve beneficiary access to medical services. Separate 
Part B coverage is specifically authorized for certain nonphysician 
practitioners' services and for services and supplies furnished as 
incident to those services.
    For purposes of this rule as it applies to nonphysician 
practitioners, we define nonphysician practitioners as nurse 
practitioners, clinical nurse specialists, certified nurse-midwives, 
and physician assistants. With respect to services and supplies 
furnished as incident to a nonphysician practitioner's services, we are 
requiring that, to be covered by Medicare, the services must meet the 
longstanding requirements in section 2050 of the Medicare Carriers 
Manual applicable to services furnished as incident to the professional 
services of a physician. Therefore, we specify, in new Secs. 410.74(b), 
410.75(d), 410.76(d), and 410.77(c) that Medicare Part B covers 
services and supplies (including drugs and biologicals that cannot be 
self-administered) furnished as incident to the nonphysician's services 
only if these services and supplies would be covered if furnished by a 
physician or furnished as incident to a physician's professional 
services. In addition, Secs. 410.74(b), 410.75(d), 410.76(d), and 
410.77(c) specify the various requirements for these incidental 
services and supplies.

Coverage and Payment for Nurse Practitioners' Services Subsequent to 
BBA

    Effective for services furnished on or after January 1, 1998, 
section 4511 of BBA authorizes nurse practitioners to bill the program 
directly for services furnished in any setting, regardless of whether 
the settings are located in rural or urban areas, but only if the 
facility or other providers of services do not charge or are not paid 
any amounts with respect to the furnishing of nurse practitioners' 
services. Accordingly, a new Sec. 410.75 of this rule specifies the 
qualifications for nurse practitioners, lists the requirements for the 
professional services of a nurse practitioner and the requirements for 
services furnished incident to the professional services of a nurse 
practitioner. This new section also specifies the process that applies 
to the provision of nurse practitioners' services.
    New Secs. 405.520(a), (b), and (c) of this rule provide the general 
rule and requirements for nurse practitioners. A new paragraph (16) is 
added to Sec. 410.150(b) to authorize payment for nurse practitioners' 
services when furnished in collaboration with a physician in all 
settings located in both rural and urban areas. A new paragraph (c) is 
added to Sec. 414.56 of this rule to set forth the payment amount for 
nurse practitioner services.
    All of the independent nurse practitioners and clinical nurse 
specialists commenting on the proposed rule and all of the major 
organizations representing these nonphysician practitioners vigorously 
opposed the proposed Federal guidelines for

[[Page 58872]]

collaboration; those provisions would apply only in States with no 
collaboration requirement.
    Comment: The commenters that objected to the proposed guidelines 
for collaboration requested that we adopt a policy that strictly defers 
to State laws, rules, and regulations regarding collaboration. The 
commenters insisted that the absence of State guidelines for 
collaboration does not necessitate the intrusion of Federal guidelines. 
In fact, they claimed that where State laws or guidelines do not 
include a requirement for collaboration, or fail to provide specific 
detailed requirements for a collaborative relationship, it is not a 
matter of accident or simple omission, but of conscious State policy 
regarding professional scope of practice. In these cases, they believe 
that there should be no collaboration requirement.
    Additionally, these commenters stated that they believe that there 
is a better understanding at the State level of the practice situations 
encountered and the evolving advancements in health care issues. 
Therefore, many States have determined that this relationship is best 
defined by the professionals themselves, rather than through detailed 
statutory legislation.
    The commenters claimed that they are not aware of any substantial 
problems in interpreting or implementing the collaboration requirement 
in the 7\1/2\ years that carriers have been applying the collaboration 
requirement without the benefit of Federal rule. According to one 
commenter, currently at least 26 States have no statutory or regulatory 
requirement for collaboration as a condition that nurses must satisfy 
in order to practice, and in the 16 States that have physician 
collaboration or supervision practice requirements, none are as 
restrictive as the guidelines that we proposed.
    One of the commenters that opposed the proposed collaboration 
guidelines stated that if more detailed provisions such as these are 
imposed on nurse practitioners and clinical nurse specialists, there 
will be a cost attached to be borne by the practitioner or consumers 
through cost shifting. Another commenter expanded upon this comment by 
posing the concern about how collaboration might affect States that 
authorize nurses to practice independently. The commenter stated that 
imposition of the collaboration requirement in ``independent practice 
States'' could create a new area for potentially fraudulent or abusive 
practices. For example, a physician may refuse to provide collaboration 
in a given area or may refuse to enter into a collaboration agreement 
unless the nurse pays a fee to the physician. This practice may violate 
the anti-kickback statute.
    One commenter stated that our proposal restricted nurses to a 
collaboration arrangement with one physician, and that the State's 
nurse practice act does not restrict nurses to a collaborative practice 
arrangement with one physician. The requirement of collaboration with 
one physician raises the cost to patients, restricts access, and 
requires unnecessary, additional services. Additionally, this same 
commenter raised concerns about the phrase in the collaboration 
guidelines that states ``or as provided by other mechanisms defined by 
Federal regulations,'' because she believes that this is the first time 
this wording has appeared in the definition of collaboration and it 
appears to give unlimited authority for regulation of practice.
    One of the professional organizations representing nurse 
practitioners maintained that the proposed collaboration guidelines 
would particularly harm Medicare beneficiaries located in rural areas, 
where nurse practitioners may be the sole source of health care within 
the community. If a nurse practitioner is not able to receive payment 
for care due to the inability to locate a physician in that geographic 
area who is able to perform the functions of a collaborating physician, 
these areas may not be served at all.
    Response: Section 6114 of OBRA 1989 established the nurse 
practitioner benefit as a separate benefit under the Medicare Part B 
program and also required that nurse practitioners collaborate with a 
physician in order for their services to be covered under Medicare. 
Therefore, nurse practitioners have always been required by Medicare 
law to collaborate with a physician. The collaboration requirement is a 
specific and distinct requirement, separate from the requirement that 
these nonphysician practitioners must practice within the scope of the 
law of the State where the services are performed.
    The 1989 Omnibus Budget Reconciliation Act, adding section 
1861(aa)(6) of the Act, defined the term, ``collaboration'' as a 
process in which a nurse practitioner works with a physician to deliver 
health care services within the scope of the practitioner's 
professional expertise, with medical direction and appropriate 
supervision as provided for in jointly developed guidelines or other 
mechanisms as provided by the law of the State in which the services 
are performed. The BBA of 1997 increased payment amounts to nurse 
practitioners and expanded the settings where they can receive 
payments, but the BBA did not change the collaboration requirement. In 
the absence of State law regarding the collaborative relationship that 
nurse practitioners must share with a physician when furnishing their 
services to Medicare beneficiaries, we must implement the collaboration 
requirement as required by law.
    However, we did not intend to introduce new burdensome requirements 
to address situations where there is no State requirement for 
collaboration. Therefore we are removing the proposed definition of 
collaboration that applies to these situations and will require that, 
in the absence of State law or regulations governing collaboration 
relationships, we will require nurse practitioners and clinical nurse 
specialists to document their scope of practice and indicate the 
relationships that they have with physicians to deal with issues 
outside their scope of practice. The proposed rule was not intended to 
require that a nurse practitioner must furnish services in 
collaboration with only one physician. We fully expect that these 
nonphysician practitioners may have collaborative relationships with 
numerous physicians and will continue to do so in the future. We did 
not intend to introduce any new costs to the practices of nurse 
practitioners and clinical nurse specialists.
    Comment: Five major associations and professional organizations 
representing physicians, medical directors, and hospitals commented in 
favor of the proposed collaboration guidelines and suggested 
alternative criteria that they believed the Medicare program should use 
to determine coverage and payment for the services of nurse 
practitioners and clinical nurse specialists.
    Two of these organizations commented that ``appropriateness'' is 
the key criterion that Medicare contractors should use in determining 
whether services of these nonphysician practitioners should be covered 
under the ``reasonable and necessary'' provisions of section 
1862(a)(1)(A) of the Act. These commenters suggested that we consider 
services to be appropriate if they are furnished by qualified 
personnel; further, the commenters believed that, in the case of 
psychiatry services, these nonphysician practitioners are not qualified 
as physicians are to perform a psychiatric diagnostic interview 
examination (CPT codes 90801 and 90802), nor are they qualified to 
furnish services represented by any of the psychotherapy CPT codes

[[Page 58873]]

that include medical evaluation and management. Therefore, these 
commenters asserted, all of the pertinent sections of the regulations 
text should be revised to read that the nonphysician practitioners are 
not performing services otherwise precluded from coverage because of 
one of the statutory coverage exclusions listed under section 
1862(a)(1)(A) of the Act.
    Response: In order for any service to be covered under Medicare, it 
must be determined to be reasonable and necessary, and therefore, 
appropriate. Accordingly, we do not believe that it is necessary to 
revise the regulations text to specify that services furnished by these 
nonphysician practitioners can be covered only when they are not 
otherwise excluded from coverage under section 1861(a)(1)(A) of the 
Act. It is already stated in the proposed rule at sections 
410.74(a)(2)(iii), 410.75(c)(3), and 410.76(c)(3) that services 
performed by any of these nonphysician practitioners are not covered if 
they are otherwise excluded from coverage because of a statutory 
exclusion. Additionally, it is our understanding that some nurse 
practitioners and clinical nurse specialists specialize in mental 
health. Therefore, if State law authorizes these nonphysician 
practitioners to perform mental health services and evaluation and 
management services that would otherwise be furnished by a physician or 
incident to a physician's services, psychiatric nurse practitioners and 
clinical nurse specialists could bill for psychiatric diagnostic 
interviews and any of the psychotherapy CPT codes that include medical 
evaluation and management.
    Comment: One association representing hospitals urged us to clarify 
in the final rule all of the settings in which separate payment to 
nurse practitioners and clinical nurse specialists will not be made. 
Also, the commenter suggested clarification regarding whether Medicare 
will continue to pay hospitals for the facility component of hospital 
outpatient department services when separate payment is made to these 
nonphysician practitioners for their professional services furnished in 
hospital outpatient departments.
    Response: Payment is made to nurse practitioners and clinical nurse 
specialists for their professional services furnished in all settings, 
with the exception of RHCs and FQHCs. (The professional services of all 
practitioners are bundled in these two settings, and Medicare payment 
is made to the facility for such services under an all-inclusive 
composite rate.) However, when these nonphysician practitioners furnish 
services in hospital outpatient departments, Medicare will continue to 
make payment to the hospital outpatient department for the facility 
component of hospital outpatient department services.
    Comment: Two other organizations commented that we should require 
that the employer of a nurse practitioner or a clinical nurse 
specialist bill for his or her professional services. The commenter 
stated that technically, some nurses can practice without direct 
supervision, but not independently of the supervising physician since 
the physician must review all records within 2 weeks. The commenter 
believes that safe and high quality medical care requires that 
diagnosis, evaluation, treatment, and management decisions be made by 
physicians who directly supervise nonphysician practitioners on-site. 
The commenter argues that, if payment is made directly to the nurses, 
the physician has no way of verifying what is billed when an employer 
relationship does not exist. Also, because collaboration does not 
require that the physician be present while services are furnished, and 
it does not require a physician to make an independent evaluation of 
each patient, there is no assurance that safe, high quality services 
are being performed.
    Response: The law no longer requires that the employers of nurse 
practitioners and clinical nurse specialists bill for their services, 
as it does for physician assistants. The law does maintain the 
requirement, however, that these nonphysician practitioners must 
furnish their services in collaboration with a physician. Nurse 
practitioners and clinical nurse specialists have been educated and 
specially trained to furnish primary care and certain other services 
that have traditionally been furnished by physicians. As long as the 
services that nonphysician practitioners furnish are medically 
reasonable and necessary, meet Medicare requirements, and fall within 
the scope of services that they are licensed to perform, the Medicare 
program covers the services.
    Comment: Numerous nurse practitioners and clinical nurse 
specialists commented that Secs. 410.75(d) and 410.76(d) that pertain 
to services and supplies furnished incident to the professional 
services of a nurse practitioner or clinical nurse specialist should be 
clarified to state that these nonphysician practitioners need not be 
present in the same room where the services are being provided, but may 
be present and available in the office suite.
    Additionally, these same commenters requested the elimination of 
the list of examples of professional services performed by nurse 
practitioners and clinical nurse specialists at Sec. Sec. 410.75(e)(3) 
and 410.76(e)(3), asserting that the list is too limited, confusing, 
and ultimately unnecessary.
    Response: We agree that it may be more appropriate to include the 
list of examples of services in manual instructions to provide guidance 
to contractors to use in processing claims. Therefore, we are removing 
the listing of examples of services that can be provided by physician 
assistants at section 410.74(d)(3), nurse practitioners at section 
410.75(e)(3), and clinical nurse specialists at section 410.76(e)(3).
    Comment: One commenter suggested a language change to the 
requirement that ``incident to'' services be of a type that are 
commonly furnished in a physician's office, to also include a reference 
to the offices of other health professionals.
    Response: The ``incident to'' requirements for nonphysician 
practitioners are the same requirements that apply to physicians and 
that have been in place since the inception of the Medicare program. 
The various ``incident to'' requirements are currently interpreted at 
section 2050 of the Medicare Carriers Manual. We will not amend any of 
the ``incident to'' requirements at this time.
    Comment: A few nurses' associations commented that the proposed 
qualifications for nurse practitioners and clinical nurse specialists 
should be amended to clarify that these individuals must be licensed or 
certified by a professional association or an accrediting body that 
has, at a minimum, eligibility requirements that meet certain 
standards. One commenter stated that the accrediting body could be one 
that is recognized by us. These commenters explained that most 
organizations that certify nurses are not professional associations 
themselves; rather they are separately incorporated accrediting bodies. 
For example, the American Nurses Association does not certify nurse 
practitioners or clinical nurse specialists, but the American Nurses 
Credentialing Center (ANCC) does by utilizing standards developed by 
the nurse profession.
    Response: Currently, the qualifications for nurse practitioners at 
section 2158 of the Medicare Carriers Manual require that such an 
individual be certified as a primary care nurse practitioner by the 
American Nurses' Association or by the National Board of Pediatric 
Nurse Practitioners and Associates. (Section 2160 of the Medicare 
Carriers Manual does not contain a specific certification criteria

[[Page 58874]]

for clinical nurse specialists.) Thus, the manual recognizes the ANCC 
as an appropriate certifying body for nurse practitioners.
    Comment: One comment made was directed specifically toward the 
qualifications for nurse practitioners at Sec. 410.75(b) of the 
proposed rule. One academy representing nurse practitioners stated that 
the intent of the law is to pay nurse practitioners who are licensed in 
their States to practice as such. Therefore, the qualifications for 
nurse practitioners should be that the individual be a registered nurse 
who is authorized to practice as a nurse practitioner in accordance 
with State law. This academy believes that the inclusion of additional 
requirements will exclude some fully qualified nurse practitioners who 
are certified by national certifying bodies that recognize 
grandfathering laws in the States and by States that currently use 
program accreditation or certification rather than national 
certification in their licensing processes for nurse practitioners.
    Response: We agree with the commenter that the intent of the law is 
to pay nurse practitioners who are licensed in their States to practice 
as such. However, we believe that State licensure should not be the 
only qualification criterion that would enable nurse practitioners to 
bill the Medicare program directly for their professional services. 
Therefore, we will revise the qualification requirements to ensure that 
for Medicare purposes, appropriate individuals can bill the program for 
services furnished to Medicare beneficiaries.
    Comment: One college representing nurse practitioners raised 
concerns about the types of services for which nurse practitioners can 
bill the Medicare program. The college stated that it wishes to ensure 
that we intend to permit a nurse practitioner to bill within a group 
practice setting for the services of all other licensed health care 
professionals and technicians in that practice. The commenter stated 
that, although the proposed rule does not indicate a problem with this 
billing arrangement, it would appreciate a specific statement from us 
about the arrangement.
    Response: A nurse practitioner within a group practice setting 
would be permitted to bill the Medicare program for the services of all 
other licensed health care professionals and technicians within the 
practice, provided the services of others in the practice are furnished 
incident to the nurse practitioner's professional services and all the 
``incident to'' requirements are met.
    Comment: The college also stated that it is concerned that the 
proposed rule does not list nurse practitioners as designated providers 
of outpatient physical therapy and outpatient speech-pathology 
services. The college asks that the language of Secs. 410.60 and 410.62 
be amended to include nurse practitioners as nonphysician practitioners 
who are authorized to bill for these types of services.
    Response: Nurse practitioners, clinical nurse specialists, and 
physician assistants may order physical therapy, occupational therapy, 
and speech-language pathology services in the case where the services 
are medically reasonable and necessary and the State in which they are 
practicing authorizes them to do so. Also, these nonphysician 
practitioners may also certify and recertify the plan of treatment for 
physical therapy, occupational therapy, and speech-language pathology 
services providing they are authorized by State law to perform such 
services. Accordingly, Sec. 410.60 and 410.62 regarding physical 
therapy, occupational therapy, and speech-language pathology will be 
revised to include these nonphysician practitioners as designated 
providers of such services.
    Result of evaluation of comments: We have determined that for 
purposes of Medicare Part B payment, a nurse practitioner must--
    <bullet> Possess a master's degree in nursing;
    <bullet> Be a registered professional nurse who is authorized by 
the State in which the services are furnished, to practice as a nurse 
practitioner in accordance with State law; and
    <bullet> Be certified as a nurse practitioner by the ANCC or other 
recognized national certifying bodies that have established standards 
for nurse practitioners as stated above.
    We have removed the alternate proposed definition of collaboration 
in Secs. 410.75(c)(2)(iv) and 410.76(c)(2)(iv) of the proposed rule. 
For purposes of Medicare coverage, the collaboration requirement will 
state that nurse practitioners and clinical nurse specialists must meet 
the standards for a collaborative process, as established by the State 
in which they are practicing. In the absence of State law governing 
collaborative relationships, collaboration is a process in which these 
nonphysician practitioners have a relationship with one or more 
physicians to deliver health care services. Such collaboration is to be 
evidenced by nurse practitioners or clinical nurse specialists 
documenting their scope of practice and indicating the relationships 
that they have with physicians to deal with issues outside their scope 
of practice. Nurse practitioners and clinical nurse specialists must 
document this collaborative process with physicians. The collaborating 
physician does not need to be present with the nurse practitioner or 
clinical nurse specialist when the services are furnished or to make an 
independent evaluation of each patient who is seen by the nurse 
practitioner or clinical nurse specialist.
    Also, we are deleting the proposed listing of examples of services 
that can be provided by physician assistants, nurse practitioners and 
clinical nurse specialists.

Coverage and Payment for Clinical Nurse Specialists' Services 
Subsequent to BBA

    Effective for services furnished on or after January 1, 1998, 
section 4511 of BBA authorizes clinical nurse specialists to bill the 
program directly for services furnished in any setting, regardless of 
whether the settings are located in rural or urban areas, but only if 
the facility or other providers of services do not charge or are not 
paid any amounts with respect to the furnishing of nurse practitioners' 
services. A new Sec. 410.76(e) of this rule sets forth this provision.
    The new Sec. 410.76(b) sets forth new qualifications for clinical 
nurse specialists. Section 410.76(c) describes the conditions of 
coverage for clinical nurse specialists' services, defines the 
collaboration process, and paragraph (d) lists the requirements for 
services furnished incident to the professional services of a clinical 
nurse specialist.
    New Sec. Sec. 405.520(a), (b), and (c) of this rule provide the 
general rule, requirements, and civil monetary penalties for clinical 
nurse specialists. A new paragraph (c) is added to Sec. 414.56 of this 
rule to set forth the payment amounts for clinical nurse specialists' 
services.
    Comment: Numerous nurses associations commented specifically about 
the qualifications for clinical nurse specialists at Sec. 410.76(b) of 
the proposed rule. They suggested that the qualifications for clinical 
nurse specialists be amended to require that a clinical nurse 
specialist be an individual who is a registered nurse currently 
licensed to practice as in the State in which he or she practices and 
have a master's degree in a defined clinical area of nursing from an 
accredited educational institution. The commenters emphasized that 
there is no need to provide for an exception as included in the 
proposed qualifications

[[Page 58875]]

for clinical nurse specialists, because the nursing profession has long 
held consensus that clinical nurse specialists be required to have a 
master's degree. Additionally, they believed that the definition of a 
clinical nurse specialist under the BBA makes it clear that a clinical 
nurse specialist must hold a master's degree. Furthermore, they stated 
that the proposed exception requirement contains erroneous information 
about the educational focus of clinical nurse specialist programs that 
may be preparatory both for primary care and specialty care.
    Response: Prior to the BBA, section 2160 of the Medicare Carriers 
Manual required that a clinical nurse specialist had to satisfy the 
applicable requirements for a clinical nurse specialist in the State in 
which the services are performed. In the absence of State requirements, 
Medicare contractors had the discretion to determine whether an 
individual's qualifications warranted Medicare payment for clinical 
nurse specialist services. However, the BBA, which established 
qualifications for clinical nurse specialists, defines a clinical nurse 
specialist as an individual who is a registered nurse and is licensed 
to practice nursing in the State in which the services are performed 
and holds a master's degree in a defined clinical area of nursing from 
an accredited educational institution. Therefore, we will implement the 
BBA qualifications for clinical nurse specialists without an exception 
for clinical nurse specialists who do not possess a master's degree.
    Comment: One independently practicing clinical nurse specialist 
argued that access to psychiatric clinical nurse specialists, in 
particular, is being denied even though they are the only mental health 
providers, other than psychiatrists, whose education, experience, and 
legal scope of practice include the management of co-morbid medical and 
psychiatric illness. Psychiatric clinical nurse specialists also 
provide services that include patient and family education to manage 
symptoms of illness and medications, evaluation and management of side 
effects, identification of adverse reactions, and evaluation of 
effectiveness of medications and psychotherapy. The commenter explained 
that all clinical nurse specialists in psychiatric nursing hold 
master's or doctoral degrees; have completed 2-years post-graduate, 
supervised, clinical experience; have passed a national board 
certification exam; and are required to obtain 75 hours of continuing 
education credit every 5 years. The commenter concluded that 
psychiatric clinical nurse specialists are the only group of mental 
health providers whose practice is being restricted.
    Response: Psychotherapy services are listed in the AMA's CPT coding 
book as ``physician services''. Nurse practitioners and clinical nurse 
specialists are authorized by the Medicare program to bill for services 
that would otherwise be furnished by a physician or incident to a 
physician's services. Accordingly, it is appropriate for the Medicare 
program to pay these nonphysician practitioners who have the specific 
training mentioned for psychotherapy services that are determined to be 
medically reasonable and necessary.
    Result of evaluation of comments: We have determined that for 
purposes of Medicare Part B payment, a clinical nurse specialist must--
    <bullet> Be a registered nurse who is currently licensed to 
practice in the State where he or she practices and be authorized to 
perform the services of a clinical nurse specialist in accordance with 
State law;
    <bullet> Have a master's degree in a defined clinical area of 
nursing from an accredited educational institution; and
    <bullet> Be certified as a clinical nurse specialist by the 
American Nurses Credentialing Center.

Coverage and Payment for Certified Nurse-Midwives' Services

    Section 13554 of OBRA 1993 (Pub. L. 103-66) amended section 
1861(gg)(2) of the Act to revise the definition of certified nurse-
midwife. The revision eliminated a limitation on coverage and included, 
as covered services, those services furnished by certified nurse-
midwives outside the maternity cycle. This change was made effective 
for services furnished on or after January 1, 1994.
    A new Sec. 410.77 of this rule lists the qualifications for 
certified nurse-midwives and provides the conditions for coverage of 
certified nurse-midwives' services. Paragraph (d) of Sec. 410.77 lists 
the coverage requirements for the professional services of certified 
nurse-midwives, while paragraph (c) lists the requirements for services 
furnished incident to the professional services of a certified nurse-
midwife.
    The comments that we received from a major college representing 
certified nurse-midwives mainly addressed the proposed qualifications 
for these individuals.
    Comment: The commenter urged that the qualifications for certified 
nurse-midwives be revised to read that the individual must--
    (1) Be legally authorized to practice as a certified nurse-midwife 
under State law or regulations;
    (2) Have successfully completed a program of study and clinical 
experience accredited by an accrediting body approved by the U.S. 
Department of Education; and
    (3) Be currently certified as a nurse-midwife by the American 
College of Nurse-Midwives or by the American College of Nurse-Midwives 
Certification Council.
    The college believed that these revised qualifications at 
Sec. 410.77(a) would eliminate the possibility of individuals being 
able to practice as certified nurse-midwives in the Medicare program 
without having to take and pass appropriate certification examinations 
that are explicitly linked to a demonstrated mastery of the ``core 
competencies'' for basic nurse-midwife practice. These revised 
qualifications would, the commenter stated, also assure greater 
uniformity of quality and competency among certified nurse-midwives who 
wish to be paid by Medicare for services that they provide to Medicare 
patients.
    Response: Section 1861(gg)(2) of the Act states that the term, 
``certified nurse-midwife'' means a registered nurse who has 
successfully completed a program of study and clinical experience 
meeting guidelines prescribed by the Secretary, or has been certified 
by an organization recognized by the Secretary. Accordingly, we are 
implementing qualifications for certified nurse-midwives that implement 
these statutory requirements.
    Comment: The other comment that the college representing certified 
nurse-midwives made was directed toward the criteria for determining 
payment to certified nurse-midwives for their professional services. 
The college stated that Sec. 410.77(d)(1) should clarify that, while 
supervision of nonphysician staff by a nurse-midwife does not 
constitute a professional service, the service provided by the 
nonphysician may be paid to the certified nurse-midwife if it meets the 
requirements of a service incident to his or her service.
    Additionally, the college suggested that Sec. 410.77(d)(3) be 
revised to state that Medicare will pay a certified nurse-midwife for 
all services that he or she is legally authorized under State law or 
regulations to furnish as a certified nurse-midwife in the State, if 
those services are also covered services under the Medicare program. 
The college suggested this change because it maintains that certified 
nurse-midwives are qualified to perform ``other services'' that might 
not be interpreted to include

[[Page 58876]]

newborn care or certain primary care services, or primary care case 
management in a managed care context, and certain States license them 
to perform these ``other services.''
    Response: The requirements pertaining to services furnished 
incident to the professional services of a certified nurse-midwife are 
listed separately at Sec. 410.77(c) of the proposed rule. We do not 
want to confuse the requirements for the professional services of 
certified nurse-midwives with the requirements that pertain to services 
furnished incident to the professional services of certified nurse 
midwives.
    Section 1861(gg)(1) defines the term, ``certified nurse-midwife 
services'' as services furnished by a certified nurse-midwife and 
services and supplies furnished as an incident to the nurse-midwife's 
service which the certified nurse-midwife is legally authorized to 
perform under State law as would otherwise be covered if furnished by a 
physician or as an incident to a physicians' service. Therefore, we 
agree with the statement made by the commenter that coverage of the 
professional services of certified nurse-midwives are not restricted to 
newborn care, certain primary care services, or primary care case 
management services if State law authorizes them to furnish ``other 
services.''
    Result of Evaluation of Comments: We have determined that for 
purposes of Medicare Part B payment, a nurse-midwife must--
    <bullet> Be a registered nurse who is legally authorized to 
practice as a nurse-midwife in the State where services are performed;
    <bullet> Have successfully completed a program of study and 
clinical experience for nurse-midwives that is accredited by an 
accrediting body approved by the U.S. Department of Education; and
    <bullet> Be certified as a nurse-midwife by the American College of 
Nurse-Midwives or the American College of Nurse-Midwives Certification 
Council. The Secretary reserves the right to determine that these 
accrediting bodies' standards are no longer sufficient for qualifying 
nurse midwives for Medicare Part B payment.
    Also, a nurse-midwife may provide services that he or she is 
legally authorized to perform under State law as a nurse-midwife, if 
the services would otherwise be covered by the Medicare program when 
furnished by a physician or incident to a physicians' professional 
services.

Coverage and Payment for Physician Assistants' Services Subsequent to 
BBA

    Effective for services furnished on or after January 1, 1998, the 
majority of the conditions for coverage of physician assistants' 
services as indicated by new Secs. 410.74(a) and (b) remain unchanged 
with the exception of the condition for coverage of physician 
assistants' services furnished in certain areas and settings. Section 
4512 of BBA removes the restrictions on the sites in which physician 
assistants may furnish their professional services, regardless of 
whether the settings are located in rural or urban areas. Physician 
assistants are authorized to furnish their professional services as 
independent nonphysician practitioners to practically all providers of 
services and suppliers of services, provided the facility or other 
provider of services do not charge or is not paid any amounts with 
respect to the furnishing of physician assistants' professional 
services. Accordingly, separate payment may be made for physician 
assistants' services in all settings, except in RHCs and FQHCs; 
physician assistant services are included as RHC and FQHC services for 
which Medicare payment is made based on an all-inclusive payment rate 
that the program makes to these facilities.
    In new Sec. 410.74(c), we proposed to amend the qualifications for 
physician assistants to recognize certification of physician assistants 
by the National Board of Certification of Orthopedic Physician 
Assistants. These qualifications would also have recognized academic 
programs for physician assistants that are accredited by either the 
Commission on Accreditation of Allied Health Education Programs or the 
American Society of Orthopedic Physician Assistants.
    Additionally, effective January 1, 1998, physician assistants have 
the option of furnishing services under a different employment 
arrangement with a physician. They can furnish services as employees of 
a physician under a W-2 form employment arrangement or they can furnish 
services as an independent contractor to a physician and receive a 1099 
form. Under either arrangement, the employer of the physician assistant 
must bill the program for physician assistants' services as required 
under Sec. 410.150(b)(15). Moreover, when an individual furnishes 
services ``incident to'' the professional services of a physician 
assistant, these ancillary services must meet the requirements under 
Sec. 410.74(a)(2)(vi)(B).
    The Medicare payment amount for a physician assistant's 
professional services as of January 1, 1998, as stated in new paragraph 
(d) of Sec. 414.52, remains at 80 percent of the lesser of either the 
actual charge or 85 percent of the physician fee schedule amount for 
professional services. Also, new Sec. 405.520 provides the general 
rule, requirements, and civil monetary penalties for physician 
assistants who furnish services under the Medicare program.
    We received a total of 140 comments on the proposed physician 
assistant qualifications. Half of all of the commenters strongly 
opposed the inclusion of orthopedic physician assistants (OPAs) under 
the qualifications for physician assistants. The others commenting on 
the inclusion of OPAs applauded and supported their inclusion and 
suggested a few minor changes to the qualifications overall.
    Comment: The commenters who strongly opposed the proposed physician 
assistant qualifications included professional organizations, 
individual physician assistants, State level professional societies and 
academies, congressional representatives, educational institutions, 
hospitals, and a board of medical examiners. The commenters stated 
overwhelmingly that the proposed qualifications for physician 
assistants inappropriately included orthopedic physician assistants and 
that orthopedic physician assistants are not physician assistants even 
if the acronyms (PA and OPA) appear to be similar. The majority of 
commenters who opposed the inclusion of OPAs noted that they would not 
object, however, if the Congress implemented a Medicare benefit that 
recognizes orthopedic physician assistants as separate independent 
nonphysician practitioners, and, in that case, there should be a 
payment differential in the amounts of payment made to physician 
assistants and orthopedic physician assistants that would reflect a 
higher payment to PAs because they have a greater career investment, 
patient care responsibility, and higher malpractice insurance costs 
than OPAs.
    The commenters stated that PAs and OPAs do not receive the same 
education and training, accreditation, certification, or State 
licensure, and their continuing medical education requirements are not 
similar. These commenters stated that the curricula for the physician 
assistant educational programs reveal that these programs emphasized 
primary care involving diagnosis and treatment of five major clinical 
disciplines (medicine, surgery, pediatrics, psychiatry, and 
obstetrics), as well as pharmacology. The training period for

[[Page 58877]]

PAs lasts anywhere from 24 to 28 months. The orthopedic educational 
programs train technical assistants to assist orthopedic surgeons, with 
an emphasis on orthopedic disease and injury, management of equipment 
and supplies, operating room techniques, cast application and removal, 
office procedures, and orientation to prosthetics and orthotics. The 
training period for OPAs lasted for no more than 24 months.
    The commenters asserted that the Commission on Accreditation of 
Allied Health Education Programs (CAAHEP) must accredit all physician 
assistant educational programs. CAAHEP is a national independent 
accrediting agency that is recognized by the U.S. Department of 
Education and sponsored by medical, allied health, and educational 
organizations. However, there are currently no existing OPA programs to 
be accredited. The AMA accredited eight orthopedic physician assistant 
educational programs from 1969 to 1974. Accreditation ceased in 1974 
when the American Academy of Orthopedic Surgeons withdrew sponsorship 
of the accreditation process.
    The commenters stated that PAs are required to take and pass a 
national examination after graduation from a physician assistant 
educational program that is certified by the National Council on 
Certification of Physician Assistants (NCCPA). The NCCPA national 
certification examination is open only to those individuals who have 
graduated from accredited physician assistant educational programs. The 
NCCPA, which provides the certified national examination, is an 
independent organization whose governing board has representatives from 
the American Medical Association, American Hospital Association, 
American Academy of Family Physicians, American Academy of Pediatrics, 
American College of Physicians, American College of Surgeons, National 
Medical Association, Association of American Medical Schools, 
Federation of State Medical Boards, U.S. Department of Defense, 
Association of Physician Assistant Programs, and the American Academy 
of Physician Assistants. The NCCPA also includes three public members.
    OPAs who have had on-the-job training or other mid-level 
paraprofessionals who challenge the exam and have had on-the-job 
training may take the examination for OPAs that is certified by the 
National Board on Certification for Orthopedic Physician Assistants 
(NBCOPA). The NBCOPA certification examination is an open examination 
and is currently reached through the Professional Testing Corporation, 
a for-profit business that administers tests for various organizations. 
The NBCOPA is comprised of six members of the American Society of 
Orthopedic Physician Assistants (ASOPA), the orthopedic physician 
assistant professional society, and an unspecified number of advisory 
members who are presumably non-voting physicians and educators. There 
is no organized medical group that sponsors or oversees the national 
certification examination for OPAs other than ASOPA.
    The commenters emphasized that all States except Mississippi 
license and regulate PAs. Forty-three States, the District of Columbia, 
and Guam have enacted laws to authorize PAs to prescribe medicine. 
Thirty-three States authorize PAs to write prescriptions for controlled 
medications. Conversely, only Tennessee specifically licenses OPAs. 
Tennessee's licensure of OPAs is, however, separate from its licensure 
of PAs. California and New York have laws referencing OPAs, but the 
laws refer to OPAs as distinct from PAs. California refers to OPAs who 
successfully completed training as OPAs from an approved California 
orthopedic physician assistant educational program in any year between 
1971 to 1974 to perform only those orthopedic medical tasks that a 
physician and surgeon may delegate. New York defines the qualifications 
for PAs in terms broad enough to include OPAs. The New York State 
regulations do not limit the acceptable examination to the NCCPA 
certification examination. Therefore, the NBCOPA certification 
examination could be considered to adequately assess entry level skills 
for the physician assistant profession. None of the other States, 
however, recognize OPAs, and none of the States specifically grant OPAs 
prescribing privileges.
    Additionally, the commenters explained that PAs are required to log 
100-hours of continuing medical education over a 2-year cycle and to 
take a recertification exam every 6 years to maintain certification as 
PAs. On the other hand, OPAs are required to complete 120 hours of 
continuing medical education every 4-years or retake the initial NBCOPA 
certification examination to maintain certification as OPAs.
    The professional organizations representing PAs and numerous 
independent PAs and congressional representatives argued that the 
proposed changes to the PA qualifications run counter to our twin goals 
of controlling costs to the Medicare program and maintaining the 
quality of services furnished to Medicare beneficiaries. There are 
approximately 49,000 surgical technologists and 3,000 registered nurse 
first assistants and an uncounted number of unlicensed medical school 
graduates (for example, from other countries). These individuals could 
potentially qualify as PAs under the proposed qualifications by getting 
the requisite orthopedic work experience and passing the orthopedic 
physician assistant examination that is certified by NBCOPA. Thus, the 
number of individuals who could qualify for payment under the PA 
benefit ultimately is substantial.
    Additionally, these commenters argued that the proposal to include 
OPAs as PAs runs counter to congressional intent because the BBA, which 
amends coverage payment for PAs, does not include any mention of OPAs. 
They state that the debate on the BBA provisions for physician 
assistants, nurse practitioners, and clinical nurse specialists did not 
include any discussion of orthopedic physician assistants or any other 
types of physician extenders, nor did the Congressional Budget Office 
consider orthopedic physician assistants or other types of specialty 
physician extenders when projecting the costs of physician assistant 
services under the BBA. Furthermore, these commenters stated that the 
primary sponsors of the 1977 Rural Health Clinic Services Act 
acknowledged the educational preparation of PAs to provide a wide range 
of primary care services to Medicare beneficiaries living in areas 
experiencing a shortage of primary care physicians. While orthopedic 
technicians may provide valuable, specialized services in assisting 
orthopedic surgeons, they do not have an educational background in 
primary care. Consequently, they are not qualified to provide the wide 
range of primary care services that the Congress anticipated when it 
recognized the need to cover and pay for the services of PAs under 
Medicare.
    Finally, the commenters urged us to require that, in order for an 
individual to qualify as a PA under Medicare, he or she must (1) 
possess State approval to practice as a PA, and (2) demonstrate either 
graduation from a physician assistant educational program accredited by 
CAAHEP or certification by NCCPA.
    The commenters who supported the inclusion of OPAs under the 
physician assistant benefit were represented by a national society and 
academy, orthopedic surgeons, independent orthopedic physician 
assistants,

[[Page 58878]]

hospitals, universities, and organizations that provide orthopedic 
surgical services. The national society representing OPAs declared that 
our clarification of the PA qualifications does not relate to payment 
because orthopedic surgeons are already paid for many services provided 
by OPAs incident to their professional services. Rather, it believes 
that the clarification is about recognition of OPAs.
    The national academy representing orthopedic surgeons, numerous 
independent orthopedic surgeons, and OPAs stated that OPAs are 
specially trained to assist orthopedic surgeons in surgical procedures 
and other services involving the total care of patients with orthopedic 
conditions of the anatomy and pathophysiology of the musculoskeletal 
organ system. Commenters state that OPAs receive extensive training 
that includes rotations in general medicine and surgery, history and 
physical assessment, and pharmacology. Additionally, they say, OPAs are 
trained to obtain medical histories, perform physical examinations, 
assist the physician in developing and implementing patient management 
plans, perform common laboratory, radiologic, and other routine 
diagnostic procedures, and provide injections, immunizations, suturing 
and wound care, among other services. Other services that these groups 
have stated that OPAs may perform include the application, fabrication 
and removal of casts, splints, braces and orthopedic hardware, emergent 
care of trauma patients, pre- and post-operative care, and serving as 
first and second assistants to orthopedic surgeons for all procedures. 
A few commenters noted that the only orthopedic experience that the 
primary care physician assistants have is received during a 6-week 
rotation within the 4-year primary care educational program.
    Many orthopedic surgeons and others stated that the specialty 
training that OPAs receive has enabled them to become extremely 
valuable to their practices freeing up orthopedic surgeons to perform 
other tasks. Also, some commenters stated that they have found PAs and 
OPAs to be equally competent and in some cases, OPAs have proven to be 
more competent than PAs. Therefore, OPAs are very quickly becoming an 
integral part of their patient care teams. A professional organization 
commented that the inclusion of OPAs under the PA benefit should not 
result in exorbitant costs to the Medicare program because there are 
only approximately 1,000 OPAs who could meet the proposed PA 
qualifications. Also, when Tennessee established State licensure for 
OPAs, the State Comptroller's office found that there was an increase 
in State revenues from fees collected and a slight, but not 
significant, increase in State expenditures for administering the 
program.
    The national society representing OPAs suggested specific language 
be added to the proposed PA qualifications to require formal education 
programs for OPAs.
    Response: After reviewing more closely information about the 
distinctions between PAs and OPAs, and after reviewing the comments 
that we received on the proposal to include OPAs as PAs, we have 
determined that it would not be appropriate to treat OPAs in the same 
way as PAs. There are substantial differences in education and 
training, certification examinations, accreditation of educational 
programs, and State licensure and regulation of PAs and OPAs. 
Additionally, we believe that the 1977 Rural Health Clinic Services 
Act, which first recognized and paid for the services of PAs under Part 
B of the Medicare program, would have specifically recognized OPAs as 
within its scope if it intended to do so. We also believe that a 
significant number of individuals, exceeding the approximately 1,000 
currently practicing OPAs, could qualify as PAs under the proposed rule 
because the national certification examination for OPAs is currently 
open to other mid-level nonphysician practitioners who challenge the 
examination and have had on-the-job training.
    Comment: We did not specifically solicit public comment in the 
proposed rule on the BBA provision that authorized PAs to provide 
services under an arrangement as independent contractors, in addition 
to performing services as an employee of entities or individuals such 
as a physician, medical group, professional corporation, hospital, 
skilled nursing facility, or nursing facility. However, we discussed, 
in the background section of the proposed rule, that effective January 
1, 1998, PAs have the option of furnishing services under an 
independent contractor arrangement. Under either arrangement, we 
explained that the employer of the PA must bill the program for 
services furnished by the PA. As a result of this discussion, one 
commenter stated that, generally, PAs have been under the direction of 
a physician, and they have not been viewed as independent contractors. 
Therefore, the commenter emphasized that clarification is needed about 
PAs performing in an independent contractor employment relationship.
    Response: Regardless of whether a PA performs services under an 
employment relationship or under an independent contractor 
relationship, the Medicare statute requires that he or she furnish 
services under the general supervision of a physician, and the employer 
of the PA must always bill for the services furnished.
    However, just as we adopt the Internal Revenue Service's definition 
of an employer/employee employment relationship, we also adopt the 
Internal Revenue Service's definition of an independent contractor 
relationship.
    Some of the distinctions between an employer/employee and an 
independent contractor relationship are that, under an independent 
contractor relationship, the employer does not generally have to 
withhold or pay any taxes on payments to independent contractors and 
the employer has virtually no behavioral or financial control over the 
independent contractor. That is, under an independent contractor 
relationship, the independent contractor works autonomously without any 
instructions from his or her employer about when, where, and how to 
work. The contractor is engaged to perform services for a specific 
project or period of time, for which he or she is paid at the 
completion of the project. Independent contractors can make a profit or 
loss. The services that the independent contractor performs may not be 
a key aspect of the employer's regular business and, therefore, an 
independent contractor may have a significant investment in the 
facilities he or she uses in performing services for the employer. 
Additionally, the employer of an independent contractor may not provide 
employee-type benefits such as insurance, a pension plan, vacation pay, 
or sick pay.
    Result of evaluation of comments: We have determined that for 
purposes of Medicare Part B payment, a physician assistant is an 
individual who--
    <bullet> Has graduated from a physician assistant educational 
program that is accredited by the National Commission on Accreditation 
of Allied Health Education Programs;
    <bullet> Has passed the national certification examination that is 
certified by the National Commission on Certification of Physician 
Assistants; and
    <bullet> Is licensed by the State to practice as a physician 
assistant.

E. Payment for Teleconsultations in Rural Health Professional Shortage 
Areas

    In section 4206 of BBA, the Congress required that, not later than 
January 1, 1999, Medicare Part B pay for professional consultations by 
a physician via interactive telecommunications systems 
(teleconsultations).
    Under section 4206(a) of BBA, payment may be made under Part B, 
provided the teleconsultation service is furnished to a beneficiary who 
resides in a county in a rural area designated as a Health Professional 
Shortage Area (HPSA). This payment is notwithstanding that the 
individual physician or practitioner providing the professional 
consultation is not at the same location as the physician or 
practitioner furnishing the service to that beneficiary. (For the 
purposes of convenience, in this section the term ``practitioner'' is 
used to mean physicians and practitioners as specified.)
    Section 4206(b) of BBA also required that the Secretary establish a 
methodology for determining the amount of payments made for a 
teleconsultation within the following parameters:
    <bullet> The payment is to be shared between the referring 
practitioner and the consulting practitioner.
    <bullet> The amount of the payment is not to exceed the current fee 
schedule amount that would be paid to the consulting practitioner.
    <bullet> The payment is not to include any reimbursement for any 
telephone line charges or any facility fees, and a beneficiary may not 
be billed for these charges or fees.
    <bullet> The payment is to be subject to the coinsurance and 
deductible requirements under section 1833 (a)(1) and (b) of the Act.
    <bullet> The payment differential of section 1848(a)(3) of the Act 
is to be applied to services furnished by nonparticipating physicians.
    <bullet> The provisions of sections 1848(g) and 1842(b)(18) of the 
Act are to apply.
    <bullet> Further, payment for the consultation service is to be 
increased annually by the update factor for physicians' services 
determined under section 1848(d) of the Act.
    In addition, the statute directs that, in establishing the 
methodology for determining the amount of payment, the Secretary take 
into account the findings of the report required by section 192 of the 
Health Insurance Portability and Accountability Act of 1996 (Public Law 
104-191), the findings of the report required by section 4206(c) of 
BBA, and any other findings related to clinical efficacy and cost-
effectiveness of telemedicine applications.

Provisions of HCFA-1906-P

    On June 22, 1998, we published a proposed rule titled ``Payment for 
Teleconsultations in Rural Health Professional Shortage Areas'' (HCFA-
1906-P) (63 FR 33882) that would implement the provisions of section 
4206 of the BBA addressing Medicare reimbursement for telehealth 
services.

Regulatory Provisions

    In proposed Sec. 410.75(a)(1), we required that as a condition for 
Medicare Part B payment for a teleconsultation, the referring and the 
consulting practitioner be any of the following:
    <bullet> A physician as described in existing Sec. 410.20.
    <bullet> A physician assistant as defined in existing Sec. 491.2.
    <bullet> A nurse practitioner as defined in existing Sec. 491.2.
    <bullet> A clinical nurse specialist as described in existing 
Sec. 424.11(e)(6).
    <bullet> A certified registered nurse anesthetist or 
anesthesiologist's assistant as defined in existing Sec. 410.69.
    <bullet> A certified nurse-midwife as defined in existing 
Sec. 405.2401.
    <bullet> A clinical social worker as defined in section 1861(hh)(1) 
of the Act.
    <bullet> A clinical psychologist as described in existing 
Sec. 417.416(d)(2).
    We required, in proposed Sec. 410.75(a)(2), that teleconsultation 
services be furnished to a beneficiary residing in a rural area as 
defined in section 1886(d)(2)(D) of the Act that is designated as an 
HPSA under section 332(a)(1)(A) of the Public Health Service Act. For 
purposes of this requirement, the beneficiary is deemed to be residing 
in such an area if the teleconsultation presentation takes place in 
such an area.
    In proposed Secs. 410.75(a)(3) through 410.75(a)(5) we specified 
further that teleconsultations must meet the following requirements in 
order to be covered by Medicare Part B:
    <bullet> The medical examination of the beneficiary must be under 
the control of the consultant practitioner.
    <bullet> The consultation must involve the participation of the 
referring practitioner, as appropriate to the medical needs of the 
patient, and as needed to provide information to
