Medicare Program; Revisions to Payment Policies Under the 
Physician Fee Schedule for Calendar Year 2003

AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The proposed rule would refine the resource-based practice 
expense relative value units (RVUs) and make other changes to Medicare 
Part B payment policy. The policy changes concern: Medicare Economic 
Index, pricing of the technical component for positron emission 
tomography (PET) scans, Medicare qualifications for clinical nurse 
specialists, a process to add or delete services to the definition of 
telehealth, definition for ZZZ global periods, global period for 
surface radiation, and an endoscopic base for urology codes. We also 
discuss the refinement of anesthesia work values, clinical social 
worker services, and how drugs are accounted for in the sustainable 
growth rate.
    We are proposing these changes to ensure that our payment systems 
are updated to reflect changes in medical practice and the relative 
value of services. We solicit comments on the proposed policy changes.
    This proposed rule also clarifies the enrollment of physical and 
occupational therapists as therapists in private practice. In addition, 
this proposed rule discusses physical and occupational therapy payment 
caps and makes technical changes to outpatient rehabilitation services.

I. Background

A. Legislative History

    Since January 1, 1992, Medicare has paid for physicians' services 
under section 1848 of the Social Security Act (the Act), ``Payment for 
Physicians'' Services.'' This section provides for three major 
elements: (1) A fee schedule for the payment of physicians' services; 
(2) limits on the amounts that nonparticipating physicians can charge 
beneficiaries; and (3) a sustainable growth rate for the rates of 
increase in Medicare expenditures for physicians' services. The Act 
requires that payments under the fee schedule be based on national 
uniform relative value units (RVUs) based on the resources used in 
furnishing a service. Section 1848(c) of the Act requires that national 
RVUs be established for physician work, practice expense, and 
malpractice expense. Section 1848(c)(2)(B)(ii)(II) of the Act provides 
that adjustments in RVUs may not cause total physician fee schedule 
payments to differ by more than $20 million from what they would have 
been had the adjustments not been made. If adjustments to RVUs cause 
expenditures to change by more than $20 million, we must make 
adjustments to preserve budget neutrality.

B. Published Changes to the Fee Schedule

    In the July 2000 proposed rule (65 FR 44177), we listed all of the 
final rules published through November 1999. In the August 2001 
proposed rule (66 FR 40372) we discussed the November 2000 final rule 
relating to the updates to the RVUs and revisions to payment policies 
under the physician fee schedule.
    In the November 2001 final rule with comment period (66 FR 55246), 
we revised the policy for resource-based practice expense RVUs; 
services and supplies incident to a physician's professional service; 
anesthesia base unit variations; recognition of CPT tracking codes; and 
nurse practitioners, physician assistants, and clinical nurse 
specialists performing screening sigmoidoscopies. We also addressed 
comments received on the June 8, 2001 proposed notice (66 FR 31028) for 
the 5-year review of work RVUs and finalized these work RVUs. In 
addition, we acknowledged comments received in response to a discussion 
of modifier-62, which is used to report the work of co-surgeons. The 
November 2001 final rule also updated the list of services that are 
subject to the physician self-referral prohibitions in order to reflect 
CPT and Healthcare Common Procedure Coding System (HCPCS) code changes 
that were effective January 1, 2002. All these revisions ensure that 
our payment systems are updated to reflect changes in medical practice 
and the relative value of services.
    The Medicare, Medicaid, and State Child Health Insurance Program 
(SCHIP) Benefits Improvement and Protection Act of 2000 (Pub. L. 106-
554) (BIPA) modernized the mammography screening benefit and authorized 
payment under the physician fee schedule effective January 1, 2002. It 
provided for biennial screening pelvic examinations for certain 
beneficiaries and expanded coverage for screening colonoscopies to all 
beneficiaries effective July 1, 2001. It provided for annual glaucoma 
screenings for high-risk beneficiaries and established coverage for 
medical nutrition therapy services for certain beneficiaries effective 
January 1, 2002. It expanded payment for telehealth services effective 
October 1, 2001; required certain Indian Health Service providers to be 
paid for some services under the physician fee schedule effective July 
1, 2001; and revised the payment for certain physician pathology 
services effective January 1, 2001. This final rule conformed our 
regulations to reflect these statutory provisions.
    The final rule also announced the calendar year 2002 physician fee 
schedule conversion factor of $36.1992.

II. Provisions of the Proposed Regulations

    This proposed rule would affect the regulations set forth at part 
410, Supplementary medical insurance (SMI) benefits and part 414, 
Payment for Part B medical and other health services.

A. Resource-Based Practice Expense Relative Value Units

1. Resource-Based Practice Expense Legislation
    Section 121 of the Social Security Act Amendments of 1994 (Pub. L. 
103-432), enacted on October 31, 1994, required us to develop a 
methodology for a resource-based system for determining practice 
expense RVUs for each physician's service beginning in 1998. In 
developing the methodology, we were to consider the staff, equipment, 
and supplies used in providing medical and surgical services in various 
settings. The legislation specifically required that, in implementing 
the new system of

[[Page 43848]]

practice expense RVUs, we apply the same budget-neutrality provisions 
that we apply to other adjustments under the physician fee schedule.
    Section 4505(a) of the Balanced Budget Act of 1997 (BBA) (Pub. L. 
105-33), enacted on August 5, 1997, amended section 1848(c)(2)(ii) of 
the Act and delayed the effective date of the resource-based practice 
expense RVU system until January 1, 1999. In addition, section 4505(b) 
of the BBA provided for a 4-year transition period from charge-based 
practice expense RVUs to resource-based RVUs.
    Further legislation affecting resource-based practice expense RVUs 
was included in the Medicare, Medicaid and State Child Health Insurance 
Program (SCHIP) Balanced Budget Refinement Act of 1999 (BBRA) (Pub. L. 
106-113), enacted on November 29, 1999. Section 212 of the BBRA amended 
section 1848(c)(2)(ii) of the Act by directing us to establish a 
process under which we accept and use, to the maximum extent 
practicable and consistent with sound data practices, data collected or 
developed by entities and organizations. These data would supplement 
the data we normally collect in determining the practice expense 
component of the physician fee schedule for payments in CY 2001 and CY 
2002. (In the 1999 final rule (64 FR 59380), we extended, for an 
additional 2 years, the period during which we would accept 
supplementary data.)
2. Current Methodology for Computing the Practice Expense Relative 
Value Unit System
    Effective with services furnished on or after January 1, 1999, we 
established a new methodology for computing resource-based practice 
expense RVUs that used the two significant sources of actual practice 
expense data we have available--the Clinical Practice Expert Panel 
(CPEP) data and the American Medical Association's (AMA) Socioeconomic 
Monitoring System (SMS) data. The methodology was based on an 
assumption that current aggregate specialty practice costs are a 
reasonable way to establish initial estimates of relative resource 
costs for physicians' services across specialties. The methodology 
allocated these aggregate specialty practice costs to specific 
procedures and, thus, can be seen as a ``top-down'' approach.
a. Major Steps
    A brief discussion of the major steps involved in the determination 
of the practice expense RVUs follows. (Please see the November 1, 2001 
final rule (66 FR 55249) for a more detailed explanation of the top-
down methodology.)
     Step 1--Determine the specialty specific practice expense 
per hour of physician direct patient care. We used the AMA's SMS survey 
of actual aggregate cost data by specialty to determine the practice 
expenses per hour for each specialty. We calculated the practice 
expenses per hour for the specialty by dividing the aggregate practice 
expenses for the specialty by the total number of hours spent in 
patient care activities.
     Step 2--Create a specialty specific practice expense pool 
of practice expense costs for treating Medicare patients. To calculate 
the total number of hours spent treating Medicare patients for each 
specialty, we used the physician time assigned to each procedure code 
and the Medicare utilization data. We then calculated the specialty 
specific practice expense pools by multiplying the specialty practice 
expenses per hour by the total physician hours.
     Step 3--Allocate the specialty specific practice expense 
pool to the specific services performed by each specialty. For each 
specialty, we divided the practice expense pool into two groups based 
on whether direct or indirect costs were involved and used a different 
allocation basis for each group.
    (i) Direct costs--For direct costs (which include clinical labor, 
medical supplies, and medical equipment), we used the procedure 
specific CPEP data on the staff time, supplies, and equipment as the 
allocation basis.
    (ii) Indirect costs--To allocate the cost pools for indirect costs, 
including administrative labor, office expenses, and all other 
expenses, we used the total direct costs combined with the physician 
fee schedule work RVUs. We converted the work RVUs to dollars using the 
Medicare CF (expressed in 1995 dollars for consistency with the SMS 
survey years).
     Step 4--For procedures performed by more than one 
specialty, the final procedure code allocation was a weighted average 
of allocations for the specialties that perform the procedure, with the 
weights being the frequency with which each specialty performs the 
procedure on Medicare patients.
b. Other Methodological Issues
    (i) Zero Physician Work Pool--For services with physician work RVUs 
equal to zero (including those services with a technical and 
professional component), we created a separate practice expense pool 
using the average clinical staff time from the CPEP data and the ``all 
physicians'' practice expense per hour.
    We then used the adjusted 1998 practice expense RVUs to allocate 
this pool to each service. Also, for all radiology services that are 
assigned physician work RVUs, we used the adjusted 1998 practice 
expense RVUs for radiology services as an interim measure to allocate 
the direct practice expense cost pool for radiology.
    (ii) Crosswalks for Specialties without Practice Expense Survey 
Data
    Since many specialties identified in our claims data did not 
correspond exactly to the specialties included in the SMS survey data, 
it was necessary to crosswalk these specialties to the most appropriate 
SMS specialty.
    (iii) Because we believe that most physical therapy services 
furnished in physicians' offices are performed by physical therapists, 
we crosswalked all utilization for therapy services in the CPT 97000 
series to the physical and occupational therapy practice expense pool.

B. Practice Expense Proposals for Calendar Year 2003

1. CPEP Data
a. Ophthalmology Services--Rank Order Anomalies
    Rank order anomalies were created in three ophthalmology families 
of codes because only certain services in each family were brought to 
the Practice Expense Advisory Committee (PEAC) for refinement, while 
CPEP data for the other codes were left unchanged. The American Academy 
of Ophthalmology has requested that we make the following changes in 
the CPEP data to ensure that the more complex services in a family of 
codes are not paid less than the simpler services and we are proposing 
to do so.
    CPT code 67820, Revise eyelashes--remove ophthane from the supply 
list.
    CPT code 67825, Revise eyelashes--remove the bipolar handpiece from 
the supply list.
    CPT code 65220, Removal foreign body from eye--use the supply list 
and clinical staff time assigned to CPT code 65222. The exam lane 
should be the only equipment assigned.
    CPT codes 92081 and 92083, Visual field examination(s)--Assign the 
same supplies and equipment as CPT code 92082; assign 35 minutes of 
clinical staff time to 92081 and 70 minutes to 92083.
b. Practice Expense Inputs for Thermotherapy Procedures
    There are three CPT codes for transurethral destruction of prostate 
tissue: CPT 53850, by microwave

[[Page 43849]]

therapy, CPT 53852, by radiofrequency thermotherapy, and CPT 53853, by 
water-induced thermotherapy (WIT). A manufacturer of WIT equipment has 
expressed concern that the practice expense inputs currently assigned 
to CPT 53853 underestimate the costs associated with that procedure 
relative to the other two codes. We have compared the inputs of the 
three codes and agree that the WIT procedure has not been assigned many 
of the basic supply and equipment inputs that are included in the CPEP 
inputs for the other two procedures. Therefore, we are proposing to 
add, on an interim basis, the following inputs: Power table, ultrasound 
unit, mayo stand, endoscopy stretcher, light source, chux, sani-wipe, 
patient education book, sterile towel, sterile gloves, specimen cup, 
alcohol swab, gauze, tape, lidocaine, betadine, 10 cc syringe, 30 cc 
syringe, sterile water, leg bag. These inputs would be in addition to 
the thermotherapy unit, treatment catheter, drainage bag, cystopak 
(which contains drapes, syringe, irrigation tubing, surgical lubricant, 
sterile cup, gauze pad and cysto tubing) and minimum visit package for 
each visit (which contains patient gown, unsterile gloves, exam table 
paper, pillow case and thermometer probe cover) that are currently 
assigned as practice expense inputs for this procedure.
    We are also proposing to change on an interim basis the staff type 
for CPT code 53853 from the RN/LPN/MTA blend to RN in order to make the 
staff type consistent among these three similar procedures. In 
addition, we have corrected for all three procedures the minutes 
assigned to each piece of equipment to reflect the intra- and post-
clinical staff times only, rather than the total clinical staff times 
as we do for all services.
    We will request that these three procedures be reexamined by the 
PEAC at the same time in order to ensure that there is a consistent 
approach to the assignment of direct cost inputs.
    We have also received questions regarding the large disparity in 
prices that we have used for the three different thermotherapy 
machines. Currently, the thermotherapy equipment for CPT code 53850 is 
priced at $180,000, code 53852 at $42,995 and code 53853 at $18,500. 
The first two prices were given to us in 1999 and we have been sent 
documentation that indicates that the prices have fallen dramatically 
since that time. This documentation indicates that the current price 
for the thermotherapy equipment for CPT 53580 is somewhere between 
$55,000 and $100,000 and for code 53852 between $25,000 and $30,000. We 
are proposing to set the prices at $60,000 and $30,000, respectively 
and are also requesting that commenters furnish any additional 
available price documentation, particularly invoices for recently 
purchased equipment, so that we can ensure that any differences in 
assigned prices accurately reflect actual differences in costs.
c. Revision to Inputs for Iontophoresis
    It has been brought to our attention that the electrodes assigned 
to the supply list for CPT code 97033, Iontophoresis, are not the type 
of electrodes required for this procedure. We are proposing to 
substitute two electrodes with a medication vesicle as the appropriate 
supply for iontophoresis.
d. Correction to Price for Sterile Water
    The current price of $40.00 for 1000 ml of sterile water that is 
listed in our CPEP supply database is incorrect. We are proposing to 
change this to $3.00.
2. Zero Physician Work Pool for Practice Expense
a. Discussion of Alternatives to the Zero Physician Work Pool
    Within the last year, there have been two reports that have 
addressed the zero physician work pool. The GAO released a report in 
October 2001 that recommended eliminating the zero physician work pool 
(GAO-02-53, page 25). The Lewin Group, under contract with us, provided 
a draft report on June 5, 2001 analyzing the zero physician work pool 
and provided several ideas that we could study as alternatives. As we 
indicated in the November 2, 1998 final rule (63 FR 58821), we created 
the zero physician work pool as an interim measure until we could 
further analyze the effect of the top-down methodology on the Medicare 
payment for services that do not have physician work RVUs. Given our 
interest in finding alternatives to the zero physician work pool, we 
have analyzed the following possible ideas:
     Eliminate the Zero Physician Work Pool.
    The Lewin Group indicated that one idea could be to eliminate the 
zero physician work pool, as recommended by the GAO (the Lewin Group, 
page 19). We do not believe that the zero physician work pool should be 
eliminated at this time. In the absence of a change to the methodology 
or additional data, eliminating the zero physician work pool would 
result in large reductions in payments for some of the specialties 
whose services are included in the pool. The Lewin Group also indicated 
that this idea is not a ``viable alternative to the current zero 
(physician) work pool approach.'' (The Lewin Group, pages 19-20).
     Develop Specialty-Specific Zero Physician Work Pools.
    Under this approach, the Lewin Group report described an idea for 
maintaining the general zero physician work pool approach with 
specialty-specific zero physician work pools (the Lewin Group, page 
20). Since the zero physician work pool is an exception to the basic 
methodology, we are not currently interested in developing another 
exception to replace it. We are interested in finding a single 
methodology that would apply to all physicians' services. While we are 
not adopting this suggestion, we do appreciate the Lewin Group's work 
in developing this and many other ideas for consideration as we make 
refinements to the practice expense methodology.
     Make Technical Component Equal Global Less Professional 
Component RVUs.
    Many of the services that are affected by the zero physician work 
pool are services that have both professional and technical components. 
Under current policy, the technical component practice expense RVU is 
determined in the zero physician work pool. It is added to the practice 
expense RVUs for the professional component determined under the basic 
methodology to determine payment for the global service. This Lewin 
Group idea would change this to make the technical component RVUs equal 
the difference between the global and the professional component RVUs 
while other zero physician work services would be returned to the basic 
methodology (The Lewin Group, page 21).
    If we were to adopt this approach, the zero physician work pool 
would no longer have any effect. The zero physician work pool would not 
have any effect on the professional and technical component services 
since the global service from the basic methodology would be used to 
derive the technical component value. The practice expense RVUs for 
other zero physician work services would be priced under the basic 
methodology. In the absence of a change to the methodology or 
additional data, this idea would result in large reductions in payments 
for some of the specialties whose services are included in the pool.
    As we have indicated above, we are concerned about adopting this 
idea at this time. While we are not currently proposing to adopt this 
idea as an alternative to the zero physician work

[[Page 43850]]

pool, we do believe there is merit in making the technical component 
value equal the difference between the global and professional 
component RVU for services that are unaffected by the zero physician 
work pool. We receive many more bills for the global than the technical 
component only. Since it is far more common to receive a global than a 
technical component only bill, it is far more likely that using the 
global to value the technical component service will result in a 
payment that is more typical of the relative actual practice expense 
associated with the service.
    For this reason, we are proposing to make the technical component 
value equal to the difference between the global and the professional 
component for procedure codes that are not included in the zero 
physician work pool. We will continue to make the global value equal to 
the sum of the professional and the technical component values for 
procedure codes that remain in the zero physician work pool. However, 
we may revisit this decision in the future if we can address issues 
related to the zero physician work pool. We have provided more detail 
on the redistributive impact of this proposal among all physician 
specialties in the impact section of this proposed rule.
     Develop Proxy Physician Work RVUs for Zero Physician Work 
Services.
    Finally, the Lewin Group described an idea that would retain work 
and direct expenses as the basic allocators of indirect costs but 
create proxy physician work values for services that have no physician 
work (the Lewin Group, pages 22-23). The GAO suggests that the basic 
method for allocating indirect expenses does not adequately account for 
the indirect costs associated with services that do not have physician 
work RVUs (GAO-02-53, page 22). We do not believe that the large 
payment reductions that would occur if some zero physician work 
services were priced under the basic methodology are necessarily 
associated with the indirect cost allocation methodology. While the 
zero physician work pool is of benefit to many of the services that 
were originally included, some specialties commented that this 
methodological change negatively affected the particular services they 
provide. As a result, we allowed specialties to request that their 
services be removed from the zero physician work pool (see July 22, 
1999 proposed rule (64 FR 39620)). If there are shortcomings in the 
indirect cost allocation for services that have zero physician work, it 
seems likely that the values for all zero physician work services would 
be adversely affected. However, since many zero physician work services 
are not adversely affected under the top down methodology, it seems 
unlikely that the indirect cost allocation explains the adverse payment 
impact that would result for some services from elimination of the zero 
physician work pool. For this reason, we do not anticipate modifying 
the indirect cost allocation for zero physician work services.
    Based on our analysis of the Lewin suggestions, we do not believe 
that allocation of either direct or indirect expenses explains the 
effect of the top down methodology on zero physician work services. 
Rather, we believe it is likely that a relatively low practice expense 
per hour for some of the specialties included in the zero physician 
work pool explains why their payments are adversely affected by its 
elimination.
    The specialties whose services are affected by the zero physician 
work pool may want to conduct supplemental practice expense surveys if 
they believe there are shortcomings in the practice expense per hour 
information that we use as part of the basic methodology. We have 
published in this issue of the Federal Register, an interim final rule 
with comment that will modify the criteria for acceptance of 
supplemental data. This should make it easier for specialties to 
incorporate new practice expense survey information into the 
methodology. Further, as we indicated previously in the November 1, 
2000 Federal Register (65 FR 65384), we believe that there are 
significant advantages to receiving practice cost information through 
multi-specialty surveys. For this reason, we would welcome a multi-
specialty practice expense survey from all of the specialties that have 
payments affected by the zero physician work pool.
b. Other Proposals for Changes to the Zero Physician Work Pool
(i) Adjustment to Oncology Supplies Practice Expense Per Hour
    In the June 5, 1998 proposed rule (63 FR 30832), we proposed an 
adjustment to the medical supplies practice expense per hour for 
oncology as a result of a concern that their inordinately high practice 
expense per hour included expenses associated with separately payable 
cancer drugs. We proposed to substitute the ``all physician'' average 
for the oncology-specific medical supplies practice expense per hour. 
We received public comments indicating that, even after excluding the 
effect of higher drug expenses, oncologists have higher medical supply 
expenses than the average physician because of high supply costs 
associated with the administration of chemotherapy. These commenters 
suggested alternatives to using the average physician rate. In our 
November 2, 1998 (63 FR 58825) final rule, we made an adjustment to the 
medical supplies practice expense per hour for oncology and indicated 
our belief that oncology medical supply expenses would not necessarily 
exceed those of the average physician. However, the adjustment has 
largely had no effect since the practice expense RVUs for chemotherapy 
administration services are determined in the zero physician work pool.
    In its October 2001 report, the GAO recommended that we examine the 
effect of the adjustment made to oncologists' reported medical supplies 
expenses per hour. GAO did not suggest a specific alternative to the 
adjustment we made (GAO-02-53, pages 24-25). Consistent with the GAO 
recommendation, we have examined this adjustment and its impact on 
Medicare payments to oncologists. Upon further review, we believe that 
there is merit in reconsidering the adjustment that we made to the 
medical supply expenses for oncologists in combination with removing 
chemotherapy administration services from the zero physician work pool.
    At this time, we have no specific information on oncology medical 
supply expenses net of separately payable drugs. However, we have 
established a process that would allow specialties to submit 
supplemental practice expense survey data to us. While the criteria for 
performing a survey require consistency with the SMS, we are amenable 
to modifications to the survey instrument so that it can address 
questions that are of concern to a specific medical specialty. For 
instance, we would allow an oncology survey to request that respondents 
distinguish between drug and other medical supply related expenses. We 
believe that using specific data on this question from a survey would 
be preferable to developing an alternative adjustment that requires us 
to make assumptions about oncology medical supply expenses. However, if 
further survey information is unavailable to us, we are considering 
information that could be used as a reasonable proxy to determine the 
portion of the supplies practice expense per hour that is attributable 
to medical supplies that are not separately payable. Such an idea was 
suggested in the public comments on the June 5, 1998 proposed rule. We 
are considering other alternatives as well. These approaches to the 
supplies

[[Page 43851]]

practice expense per hour would apply if chemotherapy administration 
services were removed from the zero physician work pool.
(ii) Change to Staff Time Used To Create the Pool
    In the November 2, 1998 final rule (63 FR 58841), we indicated that 
average clinical staff time was used in the creation of the zero 
physician work pool. Since the cost pools are created based on 
physician time and, by definition, zero physician work services have no 
physician time, we need to use staff time to create the cost pool. If 
our database indicates that multiple staff types are typically involved 
in the service, we have used an average of the different clinical staff 
times. We are proposing to create the cost pool using the highest staff 
time in place of average staff time. The impact of this proposal is 
shown in the impact section of this proposed rule.
(iii) Removal of Non-Invasive Vascular Diagnostic Study Codes From the 
Zero Physician Work Pool
    We are proposing to remove the non-invasive vascular diagnostic 
study codes (CPT codes 93875-93990) from the zero physician work pool 
based on a request from the American Association for Vascular Surgery 
and the Society for Vascular Surgery. The impact of this proposal is 
also described further in the impact section.
(iv) Removal of Immunization CPT Codes 90471 and 90472 From the Zero 
Physician Work Pool
    As discussed above, in the November 2, 1998 final rule (63 FR 
58841), in response to the many commenters who were concerned about the 
proposed reductions for services with zero physician work RVUs, we 
created a separate practice expense pool for all services with zero 
physician work RVUs. The assignment of services to this zero physician 
work pool was of benefit to most services in this expense pool. 
However, some specialties were negatively affected by this methodology, 
and we have allowed specialties to indicate whether their services 
should be priced in this pool.
    Immunization administration services do not have physician work 
RVUs and have been included in the zero physician work pool. So that 
the direct practice expense resource costs associated with the 
immunization administration services are recognized, we propose 
removing these services from the zero physician work pool methodology 
and treating them like the vast majority of services on the physician 
fee schedule. Using the direct cost practice expense inputs as 
recommended by the AMA's RUC, the proposed practice expense relative 
value units will be 0.22 for CPT code 90471 and 0.09 for CPT code 
90472. This change will nearly double payment for CPT code 90471 and 
slightly reduce payment for CPT code 90472. Procedure CPT code 90471 is 
used for immunization administration and CPT code 90472 is used for 
each additional vaccine. Since CPT code 90472 must be billed in 
conjunction with CPT code 90471, the total payment for these procedures 
will increase when billed together.
    We have not assigned immunization administration physician work 
RVUs because this service does not typically involve a physician. The 
nurse that administers the vaccine typically provides the necessary 
counseling to the patient and this time is accounted for in the 
practice expense RVU.
    In addition, we would note that not all services represented by CPT 
codes 90471 and 90472 are covered by Medicare. For example, medically 
necessary administrations of tetanus toxoid (such as following a severe 
injury) would be covered whereas preventive administration of this 
vaccine would not be covered. Also, we will consider whether the amount 
of counseling of the patient and/or family may be different for 
childhood immunizations than for the typical Medicare service. 
Therefore, we are considering whether coding changes to reflect these 
differences would be appropriate.
3. Utilization Data
    As indicated earlier, Medicare utilization is an important data 
source used in determining the practice expense RVUs. In our final rule 
published on November 2, 1998 (63 FR 58815), we used 1997 Medicare 
utilization data to create the original resource-based practice expense 
RVUs. Based on a public comment, we indicated in our November 2, 1999 
final rule (64 FR 59405) that we would use 1998 Medicare utilization to 
develop the fully implemented RVUs that appear in that final rule. 
Because these data were unavailable to us for the proposed rule, the 
first time we could act on this public comment was in the final rule. 
We have continued our policy of using the latest utilization data to 
develop each successive year's fully implemented practice expense RVUs 
during each year of the transition (see 65 FR 65436, published on 
November 1, 2000, and 66 FR 55322, published on November 1, 2001).
    While substituting the latest year's utilization data into the 
practice expense methodology generally made little difference on total 
Medicare payments per specialty, it had a larger impact on services 
that have values affected by the zero physician work pool. The practice 
expense values for the technical component and other services included 
in the zero physician work pool declined 4 percent in 2002 as a result 
of using the most recent Medicare utilization data. Since the technical 
component is used to derive the global practice expense RVUs for 
professional and technical component services, there was also a 
reduction in the practice expense RVU for the global service.
    The specialties that provide many of the services that are included 
in the zero physician work pool have expressed concern about the impact 
of the most recent data on utilization on values for their services. 
They recently suggested that we use combined utilization data from 1997 
to 2000 to determine the practice expense values. Alternatively, these 
commenters suggested using either the 1997 or 1999 utilization as a 
``base year'' until an alternative to the zero physician work pool can 
be developed. These commenters further indicated that, once an option 
is chosen, we should not use more recent utilization data until 
comprehensive reform of the zero physician work methodology is adopted.
    We believe the suggestion of using multiple years of utilization 
data in the practice expense methodology has merit. Using multiple 
years of data has the potential to minimize the effect of year to year 
case mix changes on practice expense RVUs and improves the stability of 
our payment systems. We are proposing to develop the practice expense 
RVUs using Medicare utilization data from 1997-2000. More information 
on the impact of this proposal can be found in the regulatory impact 
statement of this proposed rule.
    We also agree with the suggestion that the utilization data not 
change annually until the zero physician work pool is eliminated. In 
fact, we are reconsidering whether to continue the practice of using 
the most recent utilization to develop each successive year's practice 
expense RVUs. As we have indicated elsewhere in this and earlier rules, 
we are continuing the refinement process beyond the 1998-2002 
transition period mandated by the BBA. Once the refinement process is 
complete, we believe that the physician community has a reasonable 
expectation that the practice expense RVUs will not change from year to 
year unless further

[[Page 43852]]

refinement is undertaken. Once the initial refinement of practice 
expense RVUs is complete, we expect to make additional refinements at 
least every 5 years as provided for in section 1848(c)(2)(B) of the 
Act. As the refinement process continues, there have been fewer 
widespread changes to Medicare payments and there has been increased 
year-to-year consistency in the practice expense RVUs. We believe this 
stability would improve if we incorpoated the most recent utilization 
data into the practice expense methodology only when we undertake 
substantial refinement as part of a 5-year review. For this reason, we 
are proposing to use the 1997-2000 utilization data to develop the CY 
2003 practice expense RVUs and not further update the utilization data 
to incorporate the 2001 utilization data in this year's final rule. 
Further, we are proposing to continue using the 1997-2000 utilization 
data in the practice expense methodology until we undertake the 5-year 
review of practice expense RVUs. We invite comments on these issues.
4. Site of Service
    As part of our resource-based practice expense methodology, we make 
a distinction between the practice expense RVUs for the non-facility 
and the facility setting.
    This distinction is needed because of the higher resource costs to 
the physician in the non-facility setting when the practitioner 
typically bears the cost of the resources associated with the service. 
In addition, the distinction ensures that we do not make a duplicate 
payment for any of the practice expenses incurred in performing a 
service for a Medicare beneficiary. When the beneficiary is a facility 
patient, we pay the facility for the clinical staff, supplies, and 
equipment needed to care for the patient. A generally lower facility 
practice expense rate is paid to the practitioner. Currently, we have 
designated only hospitals, skilled nursing facilities (SNFs), and 
community mental health centers (CMHCs) as facilities for purposes of 
calculating practice expense. An ambulatory surgical center (ASC) is 
designated as a facility if it is the place of service for a procedure 
on the ASC list. All other places of service are currently considered 
non-facility.
    Several new places of service are now in use for which we need to 
assign a site-of-service designation. Also, we are proposing revisions 
to the site-of-service designation for several existing places of 
service. We are proposing to assign a facility site of service where a 
facility or other payment will be made, in addition to the physician 
fee schedule payment to the practitioner, to reflect the practice 
expenses incurred in providing a service to a Medicare patient. We are 
proposing to designate all other places of service as non-facilities.
    The following is a list of the new places of service, along with 
their place of service numerical codes and their proposed site of 
service designations using the above criteria:

04--Homeless Shelter--

    We are proposing that this be considered a nonfacility setting.

05--Indian Health Service Free-Standing Facility--

    We are proposing that this be considered a nonfacility setting.

06--Indian Health Service Provider-Based Facility--

    We are proposing that this be considered a facility setting.

07--Tribal 638--Free-Standing Facility--

    We are proposing that this be considered a nonfacility setting.

08--Tribal 638--Provider-Based Facility--

    We are proposing that this be considered a facility setting.

15--Mobile Unit

    We are proposing that this be considered a nonfacility setting.
    If a mobile unit provides a service to a facility patient, the 
appropriate place-of-service code for the facility should be used. For 
instance, if a portable X-ray service is provided to a patient in a 
Part A skilled nursing facility stay, the place of service is 31, 
Skilled Nursing Facility. No payment is made under Part B for the 
technical component of a diagnostic test, portable x-ray transportation 
or portable x-ray set up. Payment is made to the SNF for Part A 
services and includes payment for diagnostic services that may be 
needed by the patient. This policy is consistent with recommendations 
made by the Inspector General in a recent report, Review of Improper 
Payments Made by Medicare Part B for Covered Services under the Part A 
Skilled Nursing Facility Prospective Payment System (A-01-00-00538).

20--Urgent Care Facility--
    We are proposing that this be considered a nonfacility setting.
    We are proposing changes in site of service to the following 
current designations:

26--Military Treatment Facility--
    Currently this is designated as a nonfacility. We are proposing 
that this be considered a facility setting.

41--Ambulance-Land
42--Ambulance Air or Water--
    Currently codes 41 and 42 are designated as nonfacility. We would 
propose to designate them as facilities because we make payments for 
ambulance services using the ambulance fee schedule that covers the 
direct practice expense.

52--Psychiatric Facility Partial Hospitalization--
    Currently, this is designated as a nonfacility. We are proposing 
that this be considered a facility setting.

56--Psychiatric Residential Treatment Facility--
    Currently, this is designated as a nonfacility. We are proposing 
that this be considered a facility setting.
    In the chart below is a complete list of all the existing place-of-
service codes along with the appropriate site-of-service designation 
and the descriptor for each. These codes are used on all professional 
claims to specify the entity where services are furnished.

B. Anesthesia Issues

1. Five-Year Review of Anesthesia Work
    Medical and surgical services paid under the physician fee schedule 
have three separate relative value components, a work RVU, a practice 
expense RVU and a malpractice RVU. Physician anesthesia services are 
paid under the physician fee schedule, but the payment method is 
different than the payment method for physician medical and surgical 
services. Payment for anesthesia services is based on the sum of base 
units and anesthesia time units multiplied by an anesthesia CF that is 
different from the physician fee schedule CF for medical and surgical 
services.
    The law requires that we review RVUs no less than every 5 years. 
The first 5-year review of work RVUs was completed and the revised work 
RVUs were implemented in 1997. The second 5-year review (with the 
exception of anesthesia services) was completed and the revised work 
RVUs implemented in CY 2002.
    In the first 5-year review of work RVUs, we accepted the American 
Medical Association's (AMA's) Relative Value Update Committee's (RUC's) 
recommendation that the work of anesthesia services was undervalued by 
approximately 23 percent. Since anesthesia services do not have 
individual work RVUs per code, the adjustment in anesthesia work was 
made to the anesthesia CF and not to the anesthesia codes themselves. 
This resulted in a 16-percent increase in the anesthesia CF. Budget 
neutrality was maintained by making an adjustment to the general 
physician fee schedule.
    For the second 5-year review, the American Society of 
Anesthesiologists (ASA) submitted comments to us contending that the 
work of anesthesia services is still undervalued by almost 31 percent. 
The Society subsequently reduced this to a request for a 26-percent 
increase in work based on additional discussions with the RUC.
    We can impute an anesthesia work value from the current allowed 
charge for an anesthesia service. This work value can be compared to 
the work value for anesthesia services that is derived from a building 
block approach. Under the building block approach, uniform individual 
components of the anesthesia service are identified and the work value 
of each component is estimated on the basis of a comparable physician 
medical or surgical service. The ASA derived a work value for an 
anesthesia code by dividing the anesthesia service into five uniform 
components and compared the work of each component to a comparable 
medical or surgical service. The five components are--preoperative 
evaluation, equipment and supply preparation, induction period, 
postinduction period, and postoperative care and visits. Using this 
method, the ASA proposed work values for 19 high volume anesthesia 
codes. The 19 codes represent a reasonable variety of surgical 
procedure types, including general surgery, vascular surgery, 
neurosurgery, urology, orthopedics, cardiac surgery, and ophthalmology. 
The base units of the 19 anesthesia codes reviewed range from three to 
twenty units.
    During this second 5-year review of work, four RUC workgroups have 
reviewed the ASA comments and received supplemental information through 
presentations from the ASA. Most of these workgroups have expressed 
concerns about some of the intensity values that ASA assigned to the 
individual anesthesia components, most notably, the induction and 
postinduction time periods. Each of these workgroups expressed serious 
concern about extrapolating the imputed work undervaluation from the 19 
survey codes to all anesthesia service codes, even though these 19 
codes account for more than 40 percent of all anesthesia associated 
with surgical services.
    Despite the efforts of its workgroups, the RUC furnished no 
recommendation to us on whether the work of anesthesia services is 
over-or undervalued. In the November 1, 2001 physician fee schedule 
final rule, we stated that:
    The RUC has informed us that it will continue to look at anesthesia 
work beginning at its first meeting in CY 2002. We will review the RUC 
recommendation and address anesthesia work in next year's proposed 
physician fee schedule rule.
    The RUC recently presented us with the analysis and findings of its 
April 2002 anesthesia workgroup. Despite its detailed analysis and 
laborious discussions of this issue, the RUC concluded that it was 
unable to make a recommendation regarding modification to the physician 
work valuation of anesthesia codes. Specifically, the RUC indicated the 
following:
    ``The RUC, having carefully considered the information presented, 
and having a reasonable level of confidence in the data which was 
presented and developed by the RUC, is unable to make a recommendation 
to CMS regarding modification to the physician work valuation of 
anesthesia codes.''
    At the April 2002 meeting, the RUC anesthesia workgroup reviewed 
the postinduction intensity values for the 19 anesthesia codes. The 
group also

[[Page 43856]]

reviewed each anesthesia code, the benchmark surgical code, and the 
five codes mapped to that anesthesia code that accounted for the 
largest percentage of total volume. The group considered the extent to 
which the anesthesia work of the benchmark surgical code is 
representative of other surgical codes that would be covered by the 
anesthesia code.
    We will review the information forwarded by the RUC and all 
comments we receive during the comment period to determine if an 
appropriate adjustment can be made to anesthesia work. We would note 
that any such adjustment would also require an adjustment to the 
conversion factor for all physicians' services, as required by section 
1848(c)(2)(B)(ii) of the Act. For example, a 26 percent increase in 
anesthesia work, an amount which was requested last year, would require 
a reduction of about 0.4 percent in the conversion factor for all 
services. We welcome comments on these issues.
2. Add-on Anesthesia Codes
Current Policy
    As we discuss above, payment for anesthesia services is based on 
the sum of an anesthesia code-specific base unit value plus anesthesia 
time units multiplied by an anesthesia CF. If the physician is involved 
in multiple anesthesia services for the same patient during the same 
operative session, payment is based on the base unit assigned to the 
anesthesia service having the highest base unit value and anesthesia 
time that encompasses the multiple services. This policy was adopted at 
the start of the physician fee schedule in 1992 and is incorporated in 
Sec. 414.48(g).
    Claims processing manuals instruct the carrier on the method for 
handling anesthesia associated with multiple or bilateral surgical 
procedures. Under Medicare Carrier Manual (MCM) 4830 D, the carrier 
instructs the physician to report the anesthesia procedure with the 
highest base unit value with the multiple procedures modifier, ``51'', 
and to report total time across all surgical procedures. Thus, the 
carrier is recognizing payment for one anesthesia code, despite the 
billing of multiple surgical codes by a surgeon.
Proposed Policy for Add-on Codes
    In 2001 and 2002, the CPT has added new anesthesia codes, some of 
which are add-on codes. The objective is that the add-on code would be 
billed with a primary code and the base unit of each code would be 
allowed.
    In the burn area, CPT code 01953 (1 base unit) is used in 
conjunction with CPT code 01952 (5 base units). In the obstetrical 
area, CPT code 01968 (2 base units) is used in conjunction with CPT 
code 01967 (5 base units) and CPT code 01969 (5 base units) is used in 
conjunction with CPT code 01967 (5 base units).
    The application of the multiple anesthesia service policy means 
that the base units of the add-on codes would never be recognized. Only 
the base units of the primary code would be allowed. We believe that 
anesthesia add-on codes should be priced differently than other 
multiple anesthesia codes. As a result, we are proposing to revise the 
regulations in Sec. 414.46(g) to include an exception to the usual 
multiple anesthesia services policy for add-on codes.

C. Changes to the Physician Fee Schedule Update Calculation and the 
Sustainable Growth Rate (SGR)

1. Medicare Economic Index Productivity Adjustment
    In its March 2002 Report to Congress, MedPAC recommended that ``The 
Secretary should revise the productivity adjustment for physicians' 
services and make it a multifactor instead of labor-only adjustment.'' 
In this section, we review the history of the Medicare Economic Index 
(MEI) productivity adjustment, describe the current MEI productivity 
adjustment, and identify and evaluate possible alternative MEI 
productivity adjustments based on the individual contributions we 
solicited from experts on this topic. We conclude by proposing that the 
MEI productivity adjustment be changed to reflect an economy-wide 
multifactor productivity adjustment.
a. History of MEI Productivity Adjustment
    The MEI is based on the fourth sentence of section 1842(b)(3) of 
the Act that states that prevailing charge levels beginning after June 
30, 1973 may not exceed the level from the previous year except to the 
extent that the Secretary finds, on the basis of appropriate economic 
index data, that such higher level is justified by year-to-year 
economic changes. S. Rept. No. 92-1230 at 191 (1972) provides slightly 
more detail on that index, stating that:

    Initially, the Secretary would be expected to base the proposed 
economic indexes on presently available information on changes in 
expenses of practice and general earnings levels combined in a 
matter consistent with available data on the ratio of the expenses 
of practice to income from practice occurring among self-employed 
physicians as a group.

    Based on this legislative intent, in 1975, we determined that the 
MEI would be based on a broad wage measure reflecting overall earnings 
growth, rather than direct inclusion of physicians' net income. We used 
average weekly earnings of nonagricultural production (nonsupervisory) 
workers, net of worker's productivity, as the wage proxy in the initial 
MEI. We included the productivity adjustment because it avoided double 
counting of gains in earnings resulting from growth in productivity and 
produced a MEI that approximated an economy-wide output price index 
like the Consumer Price Index (CPI). The productivity adjustment we 
used was the annual change in economy-wide private nonfarm business 
labor productivity, applied only to the physicians' earnings portion of 
the MEI (then 60 percent).
    As noted, the productivity adjustment in the MEI serves to avoid 
the double counting of productivity gains. Absent the adjustment, 
productivity gains from producing additional outputs (procedures) with 
a given amount of inputs would be included in both the earnings 
component of the MEI (reflecting growth in overall economy-wide 
productivity) and in the additional procedures that are billed 
(reflecting physicians' own productivity gains). Therefore, general 
economic labor productivity growth is removed from the labor portion of 
the price update.
    The basic structure of the MEI remained relatively unchanged from 
its effective date (July 1, 1975) to 1992, although its weights were 
updated periodically and a component was added for professional 
liability insurance. Section 9331 of the Omnibus Budget Reconciliation 
Act of 1986 (Pub. L. 99-509) (OBRA) mandated a study of the MEI and a 
notice and opportunity for public comment before revision of the 
methodology for calculating the MEI. Based on this requirement, we held 
a workshop with experts on the MEI in March 1987 to discuss topics 
ranging from the specific type of index to use (Laspeyres versus 
Paasche) to revising the method of reflecting productivity changes. 
Participants in the meeting included the Federal government, the 
Physician Payment Review Commission (PPRC), the Congressional Budget 
Office, the American Medical Association (AMA), and several consulting 
firms. The meeting participants concluded that a productivity 
adjustment was appropriate and that an acceptable measure of physician-
specific productivity did not exist. Many alternative approaches were 
discussed,

[[Page 43857]]

including the use of a policy-based ``target'' measure and several 
existing economic productivity measures.
    Using recommendations from the meeting participants, we revised the 
MEI and the productivity adjustment with the implementation of the 
physician fee schedule as discussed in the November 1992 final rule (57 
FR 55896). While we retained an adjustment for economy-wide labor 
productivity, it was applied to all of the direct labor categories of 
the MEI (70.448 percent), not just physicians' earnings, and was based 
on the 10-year moving average percent change (instead of annual percent 
changes). This form of the index has been used since that time, and was 
most recently discussed in the November 1998 final rule (63 FR 58845) 
when the MEI weights were rebased to a 1996 base year.
    The Balanced Budget Act replaced the Medicare Volume Performance 
Standard (MVPS) with a Sustainable Growth Rate (SGR). Section 1848(f) 
of the Act specifies the formula for establishing yearly SGR target for 
physicians' services under Medicare. The use of SGR targets is intended 
to control the actual growth in aggregate Medicare expenditures for 
physicians' services. The SGR targets are not limits on expenditures. 
Payments for services are not withheld if the SGR target is exceeded by 
actual expenditures. Rather, the appropriate fee schedule update, as 
specified in section 1848(d)(3) of the Act, is adjusted to reflect the 
success or failure in meeting the SGR target. If expenditures are less 
than the target, the update is increased. If expenditures exceed the 
target, the update is reduced. Specifically, expenditures are allowed 
to increase by fee-for-service Medicare enrollment growth, physician 
fee increases, increases in real per capita Gross Domestic Product 
(GDP), and changes in laws or regulations. Consequently, the statute 
links allowable increases in the volume of services resulting from 
physician productivity gains--together with volume and intensity 
increases due to technology and other factors--to the real per capita 
GDP.
    When the SGR was enacted, the Congress specified continued use of 
the MEI. By 1997, this index, including its productivity adjustment, 
had been used in updating Medicare payments to physicians for over 
twenty years. We did not propose any changes to the productivity 
adjustment used in the MEI because its continued use was consistent 
with the newly mandated SGR. If we did not make the adjustment in the 
MEI, general economic productivity gains would be reflected in two of 
the SGR factors, the MEI and real per-capita GDP (which reflects real 
GDP per hour worked, or labor productivity, and hours worked per 
person). We believe it is reasonable to remove the effect of general 
economic productivity from one of these factors (the MEI) to avoid 
double counting.
b. Current MEI Productivity Adjustment
    The current MEI productivity adjustment is based on the 10-year 
moving average percent change in private nonfarm business (referred to 
hereafter as ``economy-wide'') labor productivity, published by the 
Bureau of Labor Statistics (BLS) on a quarterly basis. A 10-year moving 
average is used to limit the impact of cyclical fluctuations in 
productivity. The productivity adjustment is applied only to the direct 
labor portions of the MEI (currently estimated at 71.272 percent). 
Therefore, the MEI is not reduced by the full change in labor 
productivity, but instead by only a portion of the change.
    In addition, the most recently available historical data are used 
for the update for the upcoming calendar year (for example, data 
available through the second quarter of CY 2001 was used for the CY 
2002 update).
    Under this method, the current estimate of the existing MEI for the 
CY 2003 fee schedule update would be 2.3 percent. The 10-year moving 
average percent change in economy-wide labor productivity for the CY 
2003 update is estimated to be 2.1 percent. However, since this 
adjustment is applied only to the direct labor portion of the MEI, the 
actual adjustment would be 1.5 percent. By comparison, the most recent 
forecast by DRI-WEFA, a Global Insight Company, of the CPI for all 
items for this same period is 1.6 percent.
    As noted previously, since its original development, the MEI 
productivity adjustment has been based on economy-wide productivity 
changes. This practice arose from the fact that the physicians' 
compensation portion of the MEI is proxied to grow at the same rate as 
general earnings in the overall economy, which reflect growth in 
overall economy-wide productivity. Removing labor productivity growth 
reflected in general earnings from the labor portion of the MEI 
produces an index that is consistent with other economy-wide output 
price indexes, like the CPI. Although some commenters have argued that 
use of a physician-specific productivity measure would be more 
appropriate, no such published measure existed at the time of the MEI's 
development; nor does one exist today.
c. Research on Alternative MEI Productivity Adjustments
    We conducted a number of research activities to evaluate whether 
the current productivity adjustment is still the most appropriate 
adjustment to use in the MEI. First, we evaluated the currently 
available productivity estimates that are produced by the BLS to 
develop a better understanding of the strengths and weaknesses of these 
measures. We also reviewed the theoretical foundation of the MEI to 
understand how labor and multifactor productivity relate to the current 
physician payment system. Then we studied the limited publicly 
available data to begin to develop preliminary estimates of trends in 
physician-specific productivity to better understand the current market 
conditions facing physicians. Finally, we solicited the individual 
contributions of academic and other professional economic experts on 
prices and productivity. They included experts from MedPAC, AMA, OMB, 
Dr. Uwe Reinhardt from Princeton University, Dr. Joe Newhouse from 
Harvard University, Dr. Ernst Berndt from MIT, and Dr. Joel Popkin from 
Joel Popkin and Company (former Assistant Commissioner of Prices at 
BLS). Based on the information we gathered during these research 
efforts, we evaluated six possible options for a productivity 
adjustment to the MEI. Our findings on each of the options we 
investigated are summarized below:
     Option 1--Using a physician-specific productivity 
adjustment.
    This option would entail using an estimate of physician-specific 
productivity to adjust the MEI. This option may have some theoretical 
attractiveness, but there are major problems obtaining accurate 
measures of physician-specific productivity. First, no published 
measure of physician-specific productivity is available. The Federal 
agency that produces the official government statistics on 
productivity, BLS, does not calculate or publish productivity measures 
for any health sector. Nor are there alternative measures of physician-
specific productivity that incorporate the BLS methodology of measuring 
productivity and that would meet the BLS standard of publication. 
Second, it is not clear that using physician-specific productivity 
within the current structure of the MEI would be appropriate. Because 
we believe the MEI appropriately uses an economy-wide wage measure as 
the proxy for physician wages, using physician specific productivity 
could overstate or

[[Page 43858]]

understate the appropriate wage increase in the MEI.
    We do believe, however, that it is important to understand the rate 
of change in physician-specific productivity. Toward this end, we have 
performed our own preliminary analysis of physician-specific 
productivity, using the limited publicly available data on physician 
outputs and inputs. Our analysis attempted to simulate the methodology 
the BLS would use to measure productivity. While this information 
cannot be interpreted as an official measure of productivity, we do 
believe it is a rough indication of the current market conditions 
facing physicians. We used this information to help form our 
determination of the most appropriate productivity adjustment to 
incorporate in the MEI, fully recognizing its preliminary nature and 
other limitations. The results of our preliminary analysis suggest that 
long-run physician-specific productivity growth is currently at 
approximately the same level as economy-wide multifactor productivity 
growth. Prior to the recent period, however, our preliminary estimates 
suggested that physician productivity gains were generally 
significantly greater than general economy-wide multifactor 
productivity gains.
    As we have emphasized, our rough estimates are inadequate for 
establishing a formal basis for the productivity adjustment to the MEI. 
Nor is the underlying economic theory sufficiently compelling, at this 
time, to adopt a physician-specific productivity measure, even if a 
suitable one were available. We conclude, however, that economy-wide 
multifactor productivity growth appears to be roughly comparable to 
current physician-specific productivity growth.
     Option 2--Retaining the current productivity adjustment.
    We investigated retaining the current productivity adjustment, that 
is, applying the 10-year moving average percent change in economy-wide 
labor productivity to the labor portion of the MEI. We have applied 
economy-wide labor productivity to a portion of the index in some form 
since the inception of the MEI in 1975. This current form has been used 
since the last major revision to the index in 1992 and was developed 
from the contributions of the 1987 expert panel. That panel concluded 
that using labor productivity applied to the labor portion of the index 
was a technically sound way to account for productivity in the 
physician update. This method makes optimal use of the available data 
since labor productivity data were, and are, available on a more timely 
basis than economy-wide multifactor productivity. By applying this 
measure to the labor portion of the index, the mix of physician-
specific labor and nonlabor inputs is reflected. Also, the use of a 10-
year moving average percentage change reduces the volatility of annual 
labor productivity changes.
    Our research, however, has indicated that using multifactor 
productivity applied to the entire index is superior to using an 
economy-wide labor productivity measure applied only to the labor 
portion of the index. The experts with whom we consulted believed it 
was more appropriate to reflect the explicit contribution to output 
from all inputs. The current measure explicitly reflects the changes in 
economy-wide labor inputs but does not reflect the actual change in 
nonlabor inputs. Instead, it implicitly assumes that nonlabor inputs 
would grow at the rate necessary to produce an economy-wide multifactor 
measure that is equivalent to the current MEI productivity adjustment. 
That implicit assumption is less precise than a direct, explicit 
calculation.
    In addition, while the implicit approach produced an MEI 
productivity adjustment in most years that was reasonably consistent 
with overall multifactor productivity growth, it now appears less 
consistent with the actual change in nonlabor inputs in the economy. In 
recent years, economy-wide labor productivity has grown very rapidly. 
This acceleration is partly the result of major investments in 
computers (a nonlabor input) that have helped create a more productive 
work force. Also, the Bureau of Economic Analysis (BEA) has adopted 
methodological changes in accounting for computer software purchases in 
measuring GDP. These changes have significantly increased the measured 
historical growth rates in real GDP and labor productivity. As a result 
of these developments, the MEI productivity adjustment based on labor 
productivity applied only to the labor portion of the MEI has increased 
very rapidly. Since the multifactor definition is an explicit 
calculation of the change in economic output relative to the change in 
both labor and nonlabor inputs, it better reflects the trend changes.
    Finally, as noted previously, our preliminary estimates of 
physician-specific productivity suggest a current growth pattern that 
is similar to growth in multifactor productivity in the economy 
overall. In consideration of the economic theory underlying 
productivity measurement, especially in view of the recent developments 
in labor versus nonlabor economic input growth trends, we concluded 
that using a multifactor productivity adjustment is superior to the 
current methodology for adjustment for productivity in the MEI.
     Option 3--Changing to using economy-wide multifactor 
productivity.
    One option for adjusting for productivity gains in the MEI would be 
to continue to use an economy-wide productivity measure, but to use 
multifactor productivity applied to the entire index, instead of labor 
productivity applied to the labor portion of the MEI. As noted 
previously, this approach was recommended by MedPAC in its March 2002 
Report to the Congress. This option would better satisfy the 
theoretical requirements of an output price, in this case the MEI, by 
explicitly reflecting the productivity gains from all inputs. In 
addition, the use of economy-wide multifactor productivity would still 
be consistent with the MEI's use of economy-wide wages as a proxy for 
physician earnings. While annual multifactor productivity can fluctuate 
considerably, though usually less than labor productivity, using a 
moving-average would produce a relatively stable and predictable 
adjustment.
    Each expert with whom we consulted believed that using a 
multifactor productivity measure was theoretically superior to the 
existing method because it reflected the actual changes in nonlabor 
inputs instead of reflecting an implicit assumption. They also believed 
that the lack of timely data on multifactor productivity was not as 
important as would have appeared initially. Instead, the experts 
believed it was more appropriate that the adjustment be based on a 
long-run average that was stable and predictable rather than on annual 
changes in productivity. Thus, if a long-run average were used, the 
increased lag time associated with the availability of published data 
on multifactor productivity would become less significant. Finally, one 
expert believed that changing to economy-wide multifactor productivity 
applied to the entire MEI would make it easier to understand the 
magnitude of the productivity adjustment.
    Use of multifactor productivity to adjust the MEI poses two 
concerns. First, multifactor productivity is much harder to measure 
than labor productivity. Economic inputs other than labor hours can be 
very difficult to identify and calculate properly. The experts at BLS, 
however, have adequately overcome these difficulties, and we are 
satisfied that their official published measurements are sound for

[[Page 43859]]

the purpose at hand. Moreover, use of a 10-year moving average increase 
helps to mitigate any remaining measurement variation from year to 
year.
    The second concern relates to the timeliness of the data. BLS 
publishes multifactor productivity levels and changes only annually (as 
opposed to the quarterly release of labor productivity data) and with 
an extended time lag (about 1\1/2\ years). These timeframes arise 
unavoidably from the difficulties of measurement mentioned above, but 
imply that the timeframe of data used to adjust the MEI would not match 
that of the historical data on wages and prices underlying the MEI. For 
the CY 2003 physician payment update, for example, we would use data on 
wages and prices through the second quarter of CY 2002, but would have 
to use multifactor productivity data only through CY 2000. Although the 
misalignment of data periods is a concern, we believe it is a 
reasonable trade-off in view of the improvement offered by the explicit 
measurement of nonlabor inputs. Also, since use of a 10-year moving 
average is intended to reduce fluctuations and provide a more stable 
level of the productivity adjustment, availability of the most recent 
data is of less importance.
    The 10-year moving average percent change in economy-wide 
multifactor productivity that would be used for the CY 2003 update 
(historical data through CY 2000) is currently estimated at 0.8 
percent. Our preliminary internal analysis of physician-specific 
productivity gains suggests that these economy-wide multifactor 
measures are somewhat consistent with those trends. Thus, using 
economy-wide multifactor productivity for MEI productivity adjustment 
theoretically would be superior to using labor productivity growth 
applied to the labor portion of the MEI. In addition, the use of a 10-
year moving average would help alleviate the lag in the availability of 
the data. Lastly, the current 10-year moving average growth in economy-
wide multifactor productivity appears to be within the range we have 
estimated for physician-specific multifactor productivity. One possible 
weakness of using economy-wide multifactor productivity is that it does 
not reflect physician-specific measures, whereas the existing 
methodology reflects the distribution of labor and nonlabor inputs used 
in the production of physician services. In practice, however, the 
balance between these factors of production is not substantially 
different for physician practices versus the overall economy.
     Option 4--Changing to using economy-wide multifactor 
productivity with physician-specific input weights.
    Another option we explored was using economy-wide labor and capital 
productivity measures (which, when weighted together, produce 
multifactor productivity), but with physician-specific input weights. 
This method would better reflect the proportion of labor and capital 
inputs used by physicians, yet still reflect the explicit contribution 
to productivity of labor and nonlabor inputs. The experts with whom we 
discussed this option thought it was theoretically consistent with a 
measure of multifactor productivity, even though different productivity 
measures would be applied to different components of the MEI.
    As noted above, the labor and capital shares for the overall 
economy do not appear to vary enough from the physician-specific shares 
in the MEI to result in a significantly different measure. A weakness 
of this method is that the BLS capital productivity series is not 
widely used or cited; therefore, we are unsure of the accuracy and 
reliability of this measure. This method also adds another layer of 
complexity to the formula, however, making it more difficult to 
understand the adjustment. We would prefer that any method we choose be 
straightforward so that everyone can readily understand the adjustment. 
Overall, we believe that this method does not provide enough of a 
technical improvement to justify the added complexity that would be 
required to implement it.
     Option 5--Adjusting productivity using a ``Policy 
Standard''.
    In its March 2002 Report to the Congress, MedPAC suggested 
establishing a policy target for the productivity adjustment. Under 
this methodology, the level of the policy target would be based on the 
productivity gains that we believe physicians could attain. This level 
would be set through policy and would likely be based on a long-run 
average of either economy-wide labor or multifactor productivity (but 
could reflect other, possibly judgmental, factors). Generally, the 
level of the policy standard would remain constant for several years; 
periodically, the policy target would be reviewed, and possibly 
adjusted.
    Some of the experts we consulted believed that a policy target 
would lessen the volatility of the adjustment since the target would 
not be changed often. Conversely, others noted the large, abrupt 
changes that could result if actual economic performance deviated from 
the policy standard requiring subsequent adjustments to the standard. 
Some believed that this method adjusts for the problem of precisely 
measuring productivity. If we used a policy standard we could avoid 
having to develop an exact measure. Using a policy target, however, may 
appear arbitrary without a theoretical basis to support its use.
    The policy target recommended by MedPAC was 0.5 percentage points 
per year. Its justification for this number was the fact that the long-
run average of economy-wide multifactor productivity was close to 0.5 
percent (the most recent 10-year average is now 0.8 percent). We do not 
believe this is a preferred option for adjusting the MEI for 
productivity improvements. Our preference is to use a long-term data-
based approach that will produce results that are not inconsistent with 
a policy standard and that will automatically reflect changes in actual 
economic performance over time, and not through abrupt periodic large 
adjustments. Thus, we conclude that a policy target does not provide an 
improvement over any of the data-based methodologies.
     Option 6--Eliminate Productivity Adjustment from the MEI.
    Questions are raised occasionally as to the possibility of 
eliminating the productivity adjustment from the MEI. We did not 
consider this to be a viable option. Our research concluded that 
adjusting for productivity in the MEI is necessary to have a 
technically correct measure of an output price increase, free of 
double-counting the impact of productivity. Every expert with whom we 
consulted agreed that a productivity adjustment was appropriate. They 
believed that the important question is which adjustment is the most 
appropriate. Therefore, we conclude, again, that it is not acceptable 
for the productivity adjustment to be removed from the MEI.
d. Use of a Forecasted MEI and Productivity Adjustment
    MedPAC, in its March 2002 Report to the Congress, recommended the 
use of a forecasted MEI value, rather than the current historical 
increase. However, implementation of this option raises several legal 
as well as practical issues. The 1972 Senate Finance Committee report 
language reflects Congress' intent that the MEI should ``follow rather 
than lead'' overall inflation. Because of this, updates to the 
physician fee schedule have always been based on historical, rather 
than forecasted, MEI data. In this way, increases in the MEI do not 
lead the current measures of inflation but follow them based on 
historical trends. Furthermore, at the time of

[[Page 43860]]

implementation of the SGR system, the Congress specified that the SGR 
system should use the MEI that existed at that time, which was based on 
historical data measures. The law did not recommend or specify a change 
in the MEI methodology; the assumption is that the Congress was 
satisfied that the MEI was functioning as designed.
    If we were to change to a forecasted MEI and productivity 
adjustment, there are also several practical issues that would need to 
be addressed. One is that changing from a historical-based MEI to a 
projected MEI would cause transitional problems because there would be 
a period of data that would not be accounted for in the year of 
implementation. For example, the CY 2002 MEI update was based on 
historical data through the second quarter of 2001. If we were to use a 
forecasted MEI in the update for CY 2003, the changes between the 
second quarter of 2001 and the first quarter of 2003 would not be 
accounted for in the update. Finally, changing to a forecasted MEI and 
productivity adjustment raises additional questions about correcting 
for forecast errors. Based on these problems, we will continue to use 
historical data to make updates under the physician fee schedule.
e. Proposed Productivity Adjustment to the MEI
    Based on the research we conducted on this issue, we are proposing 
to change the methodology for adjusting for productivity in the MEI. We 
propose that the MEI used for the CY 2003 physician payment update 
reflect changes in the 10-year moving average of private nonfarm 
business (economy-wide) multifactor productivity applied to the entire 
index. The current method accounts for productivity by adjusting the 
labor portion of the MEI by the 10-year moving average change in 
private nonfarm business (economy-wide) labor productivity.
    We propose to make this change because: (1) It is theoretically 
more appropriate to explicitly reflect the productivity gains 
associated with all inputs (both labor and nonlabor); (2) the recent 
growth rate in economy-wide multifactor productivity appears more 
consistent with the current market conditions facing physicians; and 
(3) the MEI still uses economy-wide wage changes as a proxy for 
physician wage changes. We believe that using a 10-year moving average 
change in economy-wide multifactor productivity produces a stable and 
predictable adjustment and is consistent with the moving-average 
methodology used in the existing MEI. We propose that the adjustment be 
based on the latest available actual historical economy-wide 
multifactor productivity data, as measured by BLS. Based on these 
proposed changes, we currently estimate the MEI to increase 3.0 percent 
for CY 2003. This is the result of a 3.8-percent increase in the price 
portion of the MEI, adjusted downward by a 0.8-percent increase in the 
10-year moving average change in economy-wide multifactor productivity. 
Table 1 shows the detailed cost categories of the proposed MEI update 
for CY 2003. Since the current estimate of the MEI increase for CY 2003 
is based on incomplete historical data, it may change slightly before 
we announce the final MEI no later than November 1, 2002.

\1\ The rates of historical change are estimated for the 12-month period
  ending June 30, 2002, which is the period used for computing the
  calendar year 2003 update. The price proxy values are based upon the
  latest available Bureau of Labor Statistics data as of April 2002.
\2\ The weights shown for the MEI components are the 1996 base-year
  weights, which may not sum to subtotals or totals because of rounding.
  The MEI is a fixed-weight, Laspeyres-type input price index whose
  category weights indicate the distribution of expenditures among the
  inputs to physicians' services for calendar year 1996. To determine
  the MEI level for a given year, the price proxy level for each
  component is multiplied by its 1996 weight. The sum of these products
  (weights multiplied by the price index levels) over all cost
  categories yields the composite MEI level for a given year. The annual
  percent change in the MEI levels is an estimate of price change over
  time for a fixed market basket of inputs to physicians' services.
\3\ The measures of productivity, average hourly earnings, Employment
  Cost Indexes, as well as the various Producer and Consumer Price
  Indexes can be found on the Bureau of Labor Statistics website--http://
  stats.bls.gov.
\4\ Derived from a CMS survey of several major insurers (the latest
  available historical percent change data are for the period ending

n/a Productivity is factored into the MEI compensation categories as an
  adjustment to the price variables; therefore, no explicit weight
  exists for productivity in the MEI.

2. Sustainable Growth Rate (SGR)
    Section 1848(f)(2) of the Act specifies a formula for calculating 
annual SGR targets for Medicare physicians' services. The formula 
includes four factors. Section 1848(f)(2)(A) of the Act specifies that 
the first factor is the Secretary's estimate of weighted average 
percentage increase in fees for all physicians' services. We have 
calculated this factor as a weighted average of the CY 2002 fee 
increases that apply for the different types of services included in 
the definition of physicians' services for the SGR. (For a complete 
list of these services see the November 1, 2001 Federal Register (66 FR 
55316).) Drugs furnished in a physician's office that are not usually 
self-administered are generally covered ``incident to'' a physician's 
service under section 1861(s)(2)(A) of the Act and included in the SGR. 
In the past, we have used the MEI as an approximation of the drug price 
increase. In the final revisions we make to the CY 2001 SGR later this 
year, we will account for drug price growth using a refined methodology 
that uses growth in drug prices instead of the MEI as a proxy. In 
addition, we will account for drug price growth using this refined 
methodology in the SGRs for CY 2002 and subsequent years.
    Under section 1848(d) of the Act, the update for any year is equal 
to the MEI increased or decreased by an update adjustment factor 
determined using a statutory formula. The statute limits the update 
adjustment factor to +3.0 and -7.0 percentage points. On March 1, 2002, 
we provided our estimate of the CY 2003 physician fee schedule update 
to the Medicare Payment Advisory Committee (MedPAC) and made this 
information available to the public. We estimated the update adjustment 
factor would be -13.1 percent. If the only change to our March 2002 
estimate was accounting for drug price growth in the SGR, we estimate 
the update adjustment factor would be -12.8 percent. Since the statute 
limits the update adjustment factor to -7.0 percent, we expect the CY 
2002 physician fee schedule update to equal the MEI reduced by 7.0 
percentage points.

D. Pricing of Technical Components (TC) for Positron Emission 
Tomography (PET) Scans

    Currently all components of HCPCS code G0125, Lung image PET scan, 
are nationally priced. However, the technical component (TC) and global 
value for all other PET scans are carrier priced. To keep pricing 
consistent with other PET scans, we propose to have the carriers price 
the TC and global values of HCPCS code G0125.

E. Enrollment of Physical and Occupational Therapists as Therapists in 
Private Practice

    In the November 2, 1998 final rule (63 FR 58814), we defined 
private practice for physical therapists (PTs) or occupational 
therapists (OTs) to include a therapist whose practice is in an--
     Unincorporated solo practice;
     Unincorporated partnership; or
     Unincorporated group practice.
    Private practice also includes an individual who is furnishing 
therapy as an employee of one of the above, a professional corporation, 
or other incorporated therapy practice. Some carriers and fiscal 
intermediaries have interpreted the regulation to mean that 
occupational and physical therapists employed by physicians cannot be 
enrolled as therapists in private practice. In these carrier areas, 
therapy services provided in a physician's office must instead be 
billed as incident to a physician's service.
    A specialty society representing occupational therapists has 
requested that carriers be able to enroll OTs in physician-directed 
groups as occupational therapists in private practice. A group 
representing PTs believes that provider numbers should be issued only 
to PTs working as employees in practices owned and operated by 
therapists.
    We are proposing to clarify national policy--we would allow 
carriers to enroll therapists as physical or occupational therapists in 
private practice when they are employed by physician groups. We believe 
that this would reflect actual practice patterns and would permit more 
flexible employment opportunities for therapists. We also believe that 
this would increase beneficiaries' access to therapy services, 
particularly in rural areas. Therefore, we would revise Secs. 410.59 
and 410.60 to reflect this change.

F. Clinical Social Worker Services

    Currently, Sec. 410.73(b)(2)(ii) states that, for purposes of 
billing Medicare Part B, clinical social worker (CSW) services do not 
include services furnished by a CSW to an inpatient of a Medicare-
participating skilled nursing facility (SNF). Under this rule, CSWs 
cannot receive Medicare Part B payment for diagnostic and therapeutic 
mental health services when the services are furnished to patients in 
participating SNFs, but they can receive payment for these same mental 
health services when furnished in most other settings. Additionally, 
clinical psychologists (CPs) may receive Medicare Part B payment for 
these same diagnostic and therapeutic mental health services when 
furnished to patients in participating SNFs. The effective date of the 
rule that precluded Medicare Part B payment to CSWs for services 
furnished to patients in participating SNFs was June 22, 1998. However, 
the provisions under this rule were suspended for two years beyond the 
effective date. Accordingly, these provisions that terminated payment 
for CSW services in the SNF setting were delayed until June 22, 2000. 
Announcement of the two-year suspension of the provisions was made in a 
letter signed by the Administrator to the National Association of 
Social Workers rather than publishing it in the Federal Register.
    In order to redress this issue, on October 19, 2000, we published a 
notice of proposed rulemaking in the Federal Register (65 FR 62681), in 
which we proposed to pay CSWs for CPT psychiatry codes 90801, 90802, 
90816, 90818, 90821, 90823, 90826, 90828, 90846, 90847, 90853, and 
90857 when furnished to patients in participating SNFs who are not in a 
covered Part A stay. At this time, we are reprinting our proposal to 
allow CSWs to bill for the listed CPT psychiatry codes when furnished 
to patients in participating SNFs who are
