Medicare Program; Revisions to Payment Policies Under the
Physician Fee Schedule for Calendar Year 2000

AGENCY: Health Care Financing Administration (HCFA), HHS.

ACTION: Proposed rule.

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

SUMMARY: This proposed rule would make several changes affecting
Medicare Part B payment. The changes include: implementation of
resource-based malpractice insurance relative value units (RVUs);
refinement of resource-based practice expense RVUs; payment for
physician pathology and independent laboratory services, RVUs related
to ventricular assist devices, percutaneous thrombectomy of an
arteriovenous fistula, pulse oximetry, temperature gradient studies,
venous pressure determinations, and pulmonary stress testing;
discontinuous anesthesia time; optometrist services; prostate
screening; diagnostic tests; the use of an operating microscope; use of
CPT modifier -25; qualifications for nurse practitioners; an increase
in the work RVUs for pediatric services; removal of the x-ray as a
prerequisite for chiropractic manipulation; the exclusion of payment
for assisted suicide; adjustments to the practice expense RVUs for
physician interpretation of Pap smears; and revisions to the work RVUs
for new and revised CPT codes for calendar year 1999. In addition,
since we established the physician fee schedule on January 1, 1992, our
experience indicates that some of our Part B payment policies need to
be reconsidered. This proposed rule would correct inequities in
physician payment and solicits public comments on specific proposed
policy changes.

I. Background

A. Legislative History

Since January 1, 1992, Medicare has paid for physician services
under section 1848 of the Social Security Act (the Act), ``Payment for
Physicians'' Services.'' This section contains three major elements:
(1) A fee schedule for the payment of physician services; (2) a
sustainable growth rate for the rates of increase in Medicare
expenditures for physician services; and (3) limits on the amounts that
nonparticipating physicians can charge beneficiaries. 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 because of changes resulting from a review of those 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 this tolerance is exceeded, we must make adjustments to the
conversion factors (CFs) to preserve budget neutrality.

B. Published Changes to the Fee Schedule

We published a final rule on November 25, 1991 (56 FR 59502) to
implement section 1848 of the Act by establishing a fee schedule for
physician services furnished on or after January 1, 1992. In the
November 1991 final rule (56 FR 59511), we stated our intention to
update RVUs for new and revised codes in the American Medical
Association's (AMA's) Physicians' Current Procedural Terminology (CPT)
through an ``interim RVU'' process every year. The updates to the RVUs
and fee schedule policies are as follows:
November 25, 1992, a final notice with comment period on
new and revised RVUs only (57 FR 55914).
December 2, 1993, a final rule with comment period (58 FR
63626) to revise the refinement process used to establish physician
work RVUs and to revise payment policies for specific physician
services and supplies. (We solicited comments on new and revised RVUs
only.)
December 8, 1994, a final rule with comment period (59 FR
63410) to revise the geographic adjustment factor (GAF) values, fee
schedule payment areas, and payment policies for specific physician
services. The final rule also discussed the process for periodic review
and adjustment of RVUs not less frequently than every 5 years as
required by section 1848(c)(2)(B)(i) of the Act.
December 8, 1995, a final rule with comment period (60 FR
63124) to revise various policies affecting payment for physician
services including Medicare payment for physician services in teaching
settings, the RVUs for certain existing procedure codes, and to
establish interim RVUs for new and revised procedure codes. The rule
also included the final revised 1996 geographic practice cost indices
(GPCIs).
November 22, 1996, a final rule with comment period (61 FR
59490) to revise the policy for payment for diagnostic services,
transportation in connection with furnishing diagnostic tests, changes
in geographic payment areas (localities), and changes in the procedure
status codes for a variety of services.
October 31, 1997, a final rule with comment period (62 FR
59048) to revise the geographic practice cost index (GPCI), physician
supervision of diagnostic tests, establishment of independent
diagnostic testing facilities, the methodology used to develop
reasonable compensation equivalent limits, payment to participating and
nonparticipating suppliers, global surgical services, caloric
vestibular testing, and clinical consultations. The final rule also
implemented certain provisions of the Balanced Budget Act of 1997 (the
BBA) (Public Law 105-33), enacted on August 5, 1997, and implemented
the RVUs for certain existing procedure codes and established interim
RVUs for new and revised procedure codes.
November 2, 1998, a final rule with comment period (63 FR
58814) to revise the policy for resource-based practice expense RVUs,
medical direction rules for anesthesia services, and payment for
abnormal Pap smears. Also, we rebased the Medicare Economic Index from
a 1989 base year to a 1996 base year. Under the law, we are required to
develop a resource-based system for determining practice expense RVUs.
The BBA delayed, for 1 year, implementation of the resource-based
practice expense RVUs until January 1, 1999. Also, the BBA revised our
payment policy for nonphysician practitioners, for outpatient
rehabilitation services, and for drugs and biologicals not paid on a
cost or prospective payment basis. In addition, the BBA permits certain
physicians and practitioners to opt out of Medicare and furnish covered
services to Medicare beneficiaries through private contracts and
permits payment for professional consultations via interactive
telecommunication systems. Furthermore, we finalized the 1998 interim
RVUs and issued interim RVUs for new and revised codes for 1999. This
final rule also announced the calendar year 1999 Medicare physician fee
schedule conversion factor under the Medicare Supplementary Medical
Insurance (Part B) program as required by section 1848(d) of the Act.
The 1999 Medicare physician fee schedule conversion factor was
$34.7315.
This proposed rule would affect the regulations set forth at--
Part 410, Supplementary medical insurance benefits;
Part 411, Exclusions from Medicare and limitations on
Medicare payment;
Part 414, Payment for Part B medical and other services;
and

[[Page 39610]]

Part 415, Part B carrier payments for physicians' services
to beneficiaries in providers.

II. Specific Proposals for Calendar Year 1999

A. Resource-Based Malpractice Relative Value Units

1. Current Relative Value Unit System
Section 1848(c)(2)(C) of the Act requires each service paid under
the physician fee schedule be comprised of three components: work,
practice expense, and malpractice. The practice expense and malpractice
expense RVUs equal the product of the base allowed charges and the
practice expense and malpractice percentages for the service. Base
allowed charges are defined as the national average allowed charges for
the service furnished during 1991, as estimated using the most recent
data available. For most services, we used 1989 charge data ``aged'' to
reflect the 1991 payment rules, since those were the most recent data
available for the 1992 fee schedule. The work RVUs have been resource-
based since the inception of the fee schedule in 1992. They are
primarily based on a study of physician work conducted by researchers
at the Harvard School of Public Health. The work values for new and
revised codes added since 1992 are primarily based on the
recommendations of the American Medical Association's Relative Value
Update Committee (RUC). For detailed descriptions of the establishment
of resource-based work RVUs, see the June 5, 1991 proposed rule (56 FR
25792) and the November 25, 1991 final rule (56 FR 59502) on the
original fee schedule and the May 3, 1996 proposed rule (61 FR 19992)
on the five-year refinement of resource-based work RVUs.
The practice expense RVUs were not resource-based but were rather
charge-based from 1992 to 1998. In most cases, the practice expense
RVUs were calculated on a statutory formula. They were derived from the
product of ``base allowed charges'' and service-specific practice
expense percentages. The base allowed charge is the national average
allowed charge for the service furnished in 1991. The service-specific
practice expense percentage is a weighted average of the practice
expense percentages of the specialties performing the service. For new
codes after 1991, the practice expense RVUs were extrapolated from the
values for existing similar codes or from the work RVUs.
Section 121 of the Social Security Act Amendments of 1994 (Public
Law 103-432), enacted on October 31, 1994 and amended by the BBA,
required us to develop a methodology and implement resource-based
practice expense RVUs effective for services furnished in 1998. Section
4505 of the BBA postponed implementation of resource-based practice
expense RVUs until 1999 and provided for a gradual four-year
transition, with resource-based practice expense RVUs becoming fully
effective in 2002. For a detailed explanation of resource-based
practice expense RVUs see the June 5, 1998 proposed rule (63 FR 30818)
and the November 2, 1998 final rule (63 FR 58814) on the fee schedule.
Malpractice RVUs are currently charge-based, using the same
statutory formula discussed above for practice expense RVUs but using
weighted specialty-specific malpractice expense percentages and 1991
average allowed charges. As with practice expense RVUs, malpractice
RVUs for new codes after 1991 were extrapolated from similar existing
codes or from work RVUs. Section 4505(f) of the BBA requires us to
implement resource-based malpractice RVUs for services furnished
beginning in 2000. With the implementation of resource-based
malpractice RVUs and full implementation of resource-based practice
expense RVUs in 2002, all physician fee schedule RVUs will be resource-
based, thus eliminating the last vestiges of payment inequities that
resulted from charges that did not accurately reflect the relative
resources involved in providing a service.
2. Proposed Methodology for Developing Resource-Based Malpractice RVUs
The resource-based malpractice RVUs are based on actual malpractice
premium data and current Medicare payment data on allowed services and
charges, RVUs, and specialty payment percentages. Subjective judgment
is primarily limited to the mapping of Medicare specialties to the
various insurer premium risk groups.
We decided to use malpractice premium data because they represent
the actual malpractice expense to the physician. In addition,
malpractice premium data are widely available. We also considered using
procedure-specific actual malpractice claims paid data as recommended
by the Medicare Payment Advisory Committee (MEDPAC). However, we do not
believe that such an approach is viable because inquiries to
malpractice insurance experts revealed that the data are not available
in sufficient quantity and breadth to be useful. Consultation with
insurers informed us that they do not track malpractice payments on an
individual CPT procedure code basis. If any such data did exist, we
believe that they would likely be limited to a few very high-risk
procedures and not be widely and consistently available on a national
basis. Constructing national RVUs requires consistent national data for
all procedures.
Moreover, even if such data existed on a consistent national basis,
it is virtually impossible to determine which specific procedure
performed in treating an illness produced the adverse outcome leading
to the settlement or award or to accurately apportion the settlement or
award among the procedures. For example, in the case of cancer, a
symptom missed during a visit or a faulty x-ray or MRI could all
contribute to a late diagnosis. Similarly, the cause of the claim could
be the chemotherapy, the radiation therapy, the surgery, or any
combination thereof.
Discussions with the industry lead us to conclude that the primary
determinants of malpractice liability costs are physician specialty,
level of surgical involvement, and the individual physician's
malpractice history.
Actual malpractice premium data were collected for the top 20
Medicare physician specialties measured by dollars of reimbursement.
Premiums were for a $1 million/$3 million mature claims-made-policy (a
policy covering claims made rather than services provided during the
policy term). Data were collected from all 50 States, Washington, D.C.,
and Puerto Rico. Data were collected from commercial and physician-
owned insurers and from joint underwriting associations or JUAs,
typically, State government administered risk pooling insurance
arrangements in areas where commercial insurers have left the market.
Adjustments were made to reflect mandatory patient compensation fund or
PCF (a fund to pay for any claim beyond the statutory amount thereby
limiting an individual physician's liability in cases of a large suit)
surcharges in States where PCF participation is mandatory. The premium
data collected represent at least 50 percent of physician malpractice
premiums paid in each State, with the average being 77 percent.
Malpractice insurers generally use five-digit codes developed by
the Insurance Services Office (ISO), an advisory body serving property
and casualty insurers, to classify physician specialties into different
risk classes for premium rating purposes. ISO codes classify physicians
not only by specialty, but in many cases also by whether or not the
specialty performs

[[Page 39611]]

surgical procedures. A given specialty could thus have two ISO codes,
one for use in rating a member of that specialty who performs surgical
procedures and another for rating a member of that specialty who does
not perform surgery. Medicare uses its own system of specialty
classification for payment and data purposes. It was therefore
necessary to map Medicare specialties to ISO codes and insurer risk
classes. Different insurers, while using ISO codes, have their own risk
class categories. To assure consistency, we used the risk classes of
St. Paul Companies, one of the oldest and largest malpractice insurers.

classes used.

We originally considered two malpractice premium-based alternatives
for resource-based malpractice RVUs. One was based solely on specialty
premium differences and did not reflect differences in risk-of-service
among procedures provided by the specialty. Risk-of-service reflects
how services differ in their contributions to professional malpractice
liability. For example, if a physician often performs a complex,
difficult surgical procedure, this would have a larger effect on the
physician's premium risk classification than a simple office visit. We
realized that if we did not account for risk-of-service differences all
procedures that might be performed exclusively by a given specialty
would have the same resource-based malpractice RVUs, even though they
might vary considerably in effort, difficulty, total payment, and their
contribution to that specialty's malpractice liability.
The alternative which we are proposing, uses the same basic
methodology with one added computation. In order to reflect differences
in risk-of-service, in step (3) below we propose to multiply the
specialty premium-based malpractice RVUs by the procedure's work RVUs.
We believe that time, intensity, and difficulty of services are
correlated with malpractice risk. Since the work RVUs reflect
differences in time, intensity, and difficulty among procedures and are
generally accepted as accurate, we believe that they are the best
available proxy for determining risk-of-service.
Our proposed methodology is as follows:
(1) Compute a national average premium for each specialty.
Insurance rating area malpractice premiums for each specialty were
mapped to the county level. The specialty premium for each county was
then multiplied by the county total RVUs, which had been divided by the
county malpractice geographic practice cost index (GPCI) to normalize
the data for geographical differences. (Since malpractice RVUs are
multiplied by locality malpractice GPCIs in calculating fee schedule
payments, if the locality RVUs are not ``deflated'' by the malpractice
GPCIs, the locality cost differences as reflected by the GPCIs would be
counted twice.) The product of premiums and RVUs was then summed for
all counties by specialty. This number was divided by the total RVUs
for all counties for each specialty. This yields a national average
premium for each specialty.
Table 3 shows the national average premiums for the years 1990-95
for the 20 specialties on which we collected premium data. We used an
average of the 3 most recent years, 1993-95, in our calculation. We
plan to collect more recent data (1996-1998) to use in future
refinement of malpractice RVUs, but do not expect that these more
recent data will result in any significant changes since Table 3 shows
that on a national average basis malpractice premiums have been
remarkably stable in recent years.

(2) Calculate a risk factor for each specialty. Differences among
specialties in malpractice premiums reflect differences in their
malpractice exposure or risk. Relative differences among specialties in
national average malpractice premiums can be expressed as specialty
risk factors. These risk factors are an index calculated by dividing
the national average premium for each specialty by the national average
premium for the specialty with the lowest average premium, psychiatry.

(3) Calculate malpractice RVUs for each code. Resource-based
malpractice RVUs were calculated for each procedure. First, the
percentage of a specific service provided by each specialty was
determined from payment records. This percentage was then multiplied by
the specialty's risk factor. The products for all specialties for the

[[Page 39614]]

procedure are then summed, yielding a specialty-weighted malpractice
RVU reflecting the weighted malpractice costs across all specialties
for that procedure. This number was then multiplied by the procedure's
work RVUs to account for differences in risk-of-service. We realize
that adjusting for risk-of-service using work RVUs may not exactly
reflect risk-of-service differences because certain procedures with
relatively high work RVUs may have low malpractice claim frequencies
while certain procedures with relatively low work RVUs may have high
malpractice claim frequencies. We were unable to find an acceptable
alternative to work RVUs for determining risk-of-service and would
welcome any suggestions.
As mentioned above, certain specialties may have more than one IOS
rating class and risk factor. The surgical risk factor for a specialty
was used for surgical services and the non-surgical risk factor for
evaluation and management services. Also, for obstetrics/gynecology,
the lower gynecology risk factor was used for all codes except those
obviously surgical services, in which case the higher surgical risk
factor was used.
Certain codes have no physician work RVUs. The overwhelming
majority of these codes are the technical components (TCs) of
diagnostic tests, such as x-rays and cardiac catheterization, that have
a distinctly separate technical component (the taking of an x-ray by a
technician) and professional component (the interpretation of the x-ray
by a physician). Examples of other codes with no work RVUs are
audiology tests and injections and infusions. These codes are usually
done by nonphysicians, for example, audiologists and nurses,
respectively. In many cases, the non-physician or entity furnishing the
TC is distinct and separate from the physician ordering and
interpreting the test. We believe it appropriate for the malpractice
RVUs assigned to TCs to be based on the malpractice costs of the non-
physician or entity, not the professional liability of the physician.
Our proposed methodology, however, would result in zero malpractice
RVUs for codes with no physician work since we propose the use of
physician work RVUs to adjust for risk-of-service, as explained
earlier. We believe that zero malpractice RVUs may be inappropriate
because nonphysician health practitioners and entities such as IDTFs
also have malpractice liability and carry malpractice insurance.
Therefore, we are proposing to retain the current malpractice RVUs for
all services with zero work RVUs. We are open to comments and
suggestions for constructing malpractice RVUs for codes with no
physician work.
(4) Rescale for budget neutrality. The law requires that changes to
fee schedule RVUs be budget neutral. The current malpractice RVUs and
the proposed resource-based malpractice RVUs were constructed using
entirely different methodologies and data and are not directly related
to each other. Thus, the last step is to adjust for budget neutrality
by rescaling the proposed malpractice RVUs so that the total proposed
resource-based malpractice RVUs equals the total current malpractice
RVUs. The new resource-based malpractice RVUs for each procedure were
multiplied by the frequency count for that procedure to determine the
total resource-based malpractice RVUs for each procedure. This was
summed for all procedures to determine the total fee schedule resource-
based malpractice based RVUs. This was compared to the total current
charge-based malpractice RVUs, and the appropriate adjustment was made
to attain budget neutrality. The raw unadjusted resource-based
malpractice RVUs were multiplied by 0.0291 so that the conversion to
resource-based malpractice RVUs maintains the same level of
expenditures for the malpractice component.
The proposed resource-based malpractice RVUs are shown in Addendum
B. These values have been adjusted for budget neutrality on the basis
of the most recent available data. They do not reflect the final budget
neutrality adjustment, which we will make for the final rule on the
basis of more recent data. We do not believe, however, that the values
will change significantly as a result of the final budget-neutrality
adjustment.
Because of the differences in the sizes of the three fee schedule
components, implementation of the resource-based malpractice RVUs will
have much smaller payment effects than the previous implementations of
resource-based work RVUs and resource-based practice expense RVUs. On
average, work represents about 54.5 percent of payment for a procedure
under the fee schedule, practice expense about 42.3 percent, and
malpractice about 3.2 percent. Thus, a 20 percent change in practice
expense or work RVUs would yield a change in payment of about 8 to 11
percent. In contrast, a corresponding 20 percent change in malpractice
values would yield a change in payment of only about 0.6 percent. The
mean frequency-weighted current malpractice RVU is about 0.08 which
equates to about $2.78 in 1999. Estimates of the effects on payment by
specialty and selected high-volume procedures can be found in the
impact section of this rule.
We are requesting comments on our proposed methodology and
resource-based malpractice RVUs.
We are proposing to add a new Sec. 414.22(c)(3) (Relative value
units (RVUs)) to specify that, for services furnished in the year 2000
and subsequent years, the malpractice RVUs are based on the relative
malpractice insurance resources for each service.

B. Resource-Based Practice Expense Relative Value Units

1. Resource-Based Practice Expense Legislation
Section 121 of the Social Security Act Amendments of 1994 (Public
Law 103-432), enacted on October 31, 1994, requires 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 must consider the staff, equipment, and
supplies used in providing medical and surgical services in various
settings.
The legislation specifically requires that, in implementing the new
system of practice expense RVUs, we must apply the same budget-
neutrality provisions that we apply to other adjustments under the
physician fee schedule.
The BBA was enacted on August 5, 1997, before publication of the
October 1997 (62 FR 59103) final rule. Section 4505(a) of the BBA
delayed the effective date of the resource-based practice expense RVUs
until January 1, 1999. In addition, the BBA provided for the following
revisions in the requirements to change from charge-based practice
expense RVUs to resource-based RVUs.
Instead of paying for all services entirely under a resource-based
RVU system in 1999, section 4505(b) of the BBA provided for a 4-year
transition period. The practice expense RVUs for the year 1999 will be
the sum of 75 percent of charge-based RVUs and 25 percent of the
resource-based RVUs. For the year 2000, the percentages will be 50
percent charge-based RVUs and 50 percent resource-based RVUs. For the
year 2001, the percentages will be 25 percent charge-based RVUs and 75
percent resource-based RVUs. For subsequent years, the RVUs will be
totally resource-based.
Section 4505(e) of the BBA provided that, in 1998, the practice
expense RVUs would be adjusted for certain services in anticipation of
the implementation of resource-based practice expenses

[[Page 39615]]

beginning in 1999. Thus, practice expense RVUs for office visits were
increased. For other services whose practice expense RVUs exceeded 110
percent of the work RVUs and which were furnished less than 75 percent
of the time in an office setting, the 1998 practice expense RVUs were
reduced to a number equal to 110 percent of the work RVUs. This
limitation did not apply to services that had proposed resource-based
practice expense RVUs in the June 18, 1997 proposed rule (62 FR 33196)
that increased from their 1997 practice expense RVUs. The procedure
codes affected and the final RVUs for 1998 were published in the
October 31, 1997 final rule (62 FR 59103).
Section 4505(d)(3) also required that a proposed rule be published
by May 1, 1998, with a 90-day comment period. A final rule was
published on November 2, 1998 and the transition began on January 1,
1999.
The BBA also required that we develop new resource-based practice
expense RVUs. In developing these new practice expense RVUs, section
4505(d)(1) required us to--(1) use, to the maximum extent practicable,
generally accepted accounting principles that recognize all staff,
equipment, supplies, and expenses, not just those that can be tied to
specific procedures, and use actual data on equipment use and other key
assumptions; (2) consult with organizations representing physicians
regarding the methodology and data to be used; and (3) develop a
refinement process to be used during each of the four years of the
transition period.
2. Current Methodology for Computing Practice Expense Relative Value
Units
Effective with services furnished after January 1, 1999, we
established a new methodology for computing resource-based practice
expense RVUs that uses 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's)
Socioeconomic Monitoring System (SMS) data. This methodology is based
on an assumption that current aggregate specialty practice costs are a
reasonable basis for establishing initial estimates of relative
resource costs of physicians' services across specialties. It then
allocates these aggregate specialty practice costs to specific
procedures and, thus, can be seen as a ``top-down'' approach. The
following summarizes the general methodology used. (For more specific
information refer to the June 5, 1998 proposed rule (63 FR 30826) and
the November 2, 1998 final rule with comment (63 FR 58816).)

Practice Expense Cost Pools

We used actual practice expense data by specialty, derived from the
1995 through 1997 SMS survey data, to create six cost pools:
administrative labor, clinical labor, medical supplies, medical
equipment, office supplies, and all other expenses. There were three
steps in the creation of the cost pools. They are as follows:
Step (1) We used the AMA's SMS survey of actual cost data to
determine practice expenses per hour by cost category. The practice
expense per hour for each physician respondent's practice was
calculated as the practice expenses for the practice divided by the
total number of hours spent in patient care activities by the
physicians in the practice. The practice expenses per hour for the
specialty are an average of the practice expenses per hour for the
respondent physicians in that specialty.
Step (2) We determined the total number of physician hours, by
specialty, spent treating Medicare patients. This was calculated from
physician time data for each procedure code and the Medicare claims
data. The primary sources for the physician time data were surveys
submitted to the AMA's RUC and surveys performed and developed by a
research team at the Harvard School of Public Health in a cooperative
agreement with us for the initial establishment of the work RVUs.
Step (3) We then calculated the practice expense pools by specialty
and by cost category by multiplying the practice expenses per hour for
each category by the total physician hours.
For services with work RVUs equal to zero (including the TC of
services with PC and TC), we created a separate practice expense pool
using the average clinical staff time from the CPEP data (since these
codes by definition do not have physician time), and the ``all
physicians'' practice expense per hour.

Cost Allocation Methodology

For each specialty, we separated the six practice expense pools
into two groups, direct costs and indirect costs, and used a different
allocation basis for each group.
For direct costs, which include clinical labor, medical
supplies, and medical equipment, we used the CPEP data as the
allocation basis. The CPEP data for clinical labor, medical supplies,
and medical equipment were used to allocate the clinical labor, medical
supplies, and medical equipment cost pools, respectively.
For the separate practice expense pool for services with work RVUs
equal to zero, we are using, as an interim measure, 1998 practice
expense RVUs to allocate the direct cost pools (clinical labor, medical
supplies and medical equipment).
Also, for all radiology services that are assigned work RVUS, we
used the 1998 practice expense RVUs as an interim measure to allocate
the direct practice expense cost pool for the specialty of radiology.
For all other specialties that perform radiology services that are
assigned work RVUs, we used the CPEP data for radiology services in the
allocation of that specialty's direct practice expense cost pools.
For indirect costs, which include administrative labor,
office expenses, and all other expenses, we used the total direct costs
or the 1998 practice expense RVUs, as described above, in combination
with the physician fee schedule work RVUs, to allocate the cost pools.
We converted the work RVUs to dollars using the Medicare CF (expressed
in 1995 dollars for consistency with the SMS survey years).
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.

Other Methodological Issues

Global Practice Expense Relative Value Units.
For services with the PC and TC paid under the physician fee
schedule, the global practice expense RVUs are set equal to the sum of
the PC and TC.
Practice Expenses per Hour Adjustments and Specialty
Crosswalks
Since many specialties identified in our claims data did not
correspond exactly to the specialties included in the practice expenses
tables from the SMS survey data, it was necessary to crosswalk these
specialties to the most appropriate SMS specialty category. We also
made the following adjustments to the practice expense per hour data
(For the rationale for these adjustments, see the November 2, 1998
proposed rule):
+ We set the medical materials and supplies practice expenses per
hour for the specialty of ``oncology'' equal to the ``all physician''
medical materials and supplies practice expenses per hour.
+ We based the administrative payroll, office, and other practice
expenses per hour for the specialties of ``physical therapy'' and
``occupational therapy'' on data used to develop the salary equivalency
guidelines for these

[[Page 39616]]

specialties. We set the practice expense per hour for the direct cost
categories equal to the ``all physicians'' practice expense per hour
from the SMS survey data.
+ Due to uncertainty concerning the appropriate crosswalk and time
data for the nonphysician specialty ``audiologist,'' we derived the
resource-based practice expense RVUs for codes performed by
audiologists from the practice expenses per hour of the other
specialties that perform these codes.
+ For the specialty ``emergency medicine'' we used the ``all
physician'' practice expense per hour to create practice expense cost
pools for the categories ``clerical payroll'' and ``other expenses.''
+ For the specialty ``podiatry'' we used the ``all physician''
practice expenses per hour to create the practice expense pool.
+ For the specialty ``pathology'' we removed the supervision and
autopsy hours reimbursed through Part A of the Medicare program from
the practice expense per hour calculation.
+ For the specialty ``maxillofacial prosthetics'' we used the ``all
physician'' practice expenses per hour to create practice expense cost
pools and, as an interim measure, allocated these pools using the 1998
practice expense RVUs.
+ We split the specialty ``radiology'' practice expense per hour
into ``radiation oncology'' practice expense per hour and ``radiology
other than radiation oncology'' practice expense per hour and used this
split practice expense per hour to create practice expense cost pools
for these specialties.
+ Time Associated with the Work Relative Value Units.
The time data resulting from the refinement of the work RVUs have
been, on the average, 25 percent greater than the time data obtained by
the Harvard research team for the same services. We increased the
Harvard research team's time data to ensure consistency between these
data sources.
For services with no assigned physician times, such as dialysis,
physical therapy, psychology and many radiology and other diagnostic
services, we calculated estimated total physician times based on work
RVUs, maximum clinical staff time for each service as shown in the CPEP
data, or the judgment of our clinical staff.
We calculated the time for the anesthesia CPT codes 00100 through
01996 using the base and time units from the anesthesia fee schedule
and the Medicare allowed claims data.
3. Refinement

Background

Section 4505(d)(1)(C) of the BBA requires us to develop a
refinement process to be used during each of the four years of the
transition period. In the June 1998 proposed rule, (63 FR 30823), we
did not propose a specific long-term refinement process. Rather, we set
out the parameters for an acceptable refinement process for practice
expense RVUs and solicited comments on our proposed process. Most of
the approximately 14,000 comments we received on the proposed rule
approved of our general ``top down'' approach to the calculation of
practice expense RVUs. However, many concerns were raised regarding the
specific steps in our methodology, the practice expense per hour data,
and detailed code level data. In response to these comments, we made
adjustments for those situations in which we were convinced an
adjustment was appropriate without the need for further data or input
(see the November 2, 1998 (63 FR 58818) final rule). We also indicated
that we would consider other comments for possible future refinement
and that RVUs for all codes would be considered interim for 1999 and
for future years during the transition period.
As part of the initial refinement process, in the November 2, 1998
final rule, page 58818, we outlined the steps we are undertaking to
resolve the outstanding general methodological issues. These steps
include--the establishment of a mechanism to receive additional
technical advice for dealing with these broad practice expense RVU
methodological issues; evaluation of any additional recommendations
from the GAO, MEDPAC, and the Practicing Physicians Advisory Council;
and consultation with physicians' and other groups about these issues.
In addition, we solicited comments and suggestions about methodology
from organizations that have a broad range of interest and expertise in
practice expense and survey issues. We especially encouraged
organizations that represent a broad range of physician, practitioner,
and provider groups (for example, groups that represent both
specialties receiving increases and those receiving decreases in
Medicare payments) with expertise in practice cost issues to make
specific recommendations regarding such issues as criteria for using
alternative survey data, methods for validating data collected in the
future, and possible alternatives for the allocation of indirect
expenses.
We also discussed a proposal submitted by the RUC, which was
supported by almost every medical specialty society, for the
establishment of a Practice Expense Advisory Committee (PEAC), to
review comments and make recommendations on the code-specific CPEP data
(that is, the clinical staff types and times, medical supplies, and
medical equipment needed for each procedure) during this refinement
period. This committee would report to the RUC, which would make final
recommendations to us.
Current Status of Refinement Activities
As stated above, one of our main strategies for resolving the
outstanding practice expense methodological issues was to seek a
mechanism for obtaining expert advice and technical support. To this
end we have awarded a contract beginning in May 1999 to obtain this
assistance in evaluating various aspects of our practice expense
methodology. As also discussed above, the RUC, through the PEAC, will
give us recommendations on the refinement of procedure-specific inputs.
The PEAC held its organizing meeting in February 1999 and met again in
April to begin the task of refining the code-specific CPEP data.
We believe that the awarding of the methodological support contract
and the establishment of the PEAC represent important steps in our
refinement process. However, at this time, our contractor has just
begun the task of assisting us with the major methodological issues
that we face in refining the resource-based practice expense RVUs. In
addition, the PEAC's recommendations on changes to the code-level
inputs have not yet been forwarded by the RUC. Therefore, we are able
to propose only a few changes in our practice expense methodology or in
the code-specific inputs in this proposed rule. However, we will
consider additional changes for the final rule, based on any
recommendations we receive from the RUC or PEAC or other commenters.
These changes, if accepted, would be established as interim values and
would be effective January 1, 2000. The following discusses more
specifically the status of refinement activities and the specific
changes we are proposing for the various aspects of our practice
expense methodology.

Top-Down Methodology

As we have already discussed, we now have a contractor to assist us
in refining our practice expense methodology. This support will help us
to pinpoint weaknesses in our top-down methodology and will also aid us
in generating alternative solutions to the identified problems. Among
the

[[Page 39617]]

activities we have requested the contractor to undertake are:
The evaluation of the validity and reliability of SMS data
for the specialty and subspecialty groups.
The identification and evaluation of alternative and
supplementary data sources from specialty and multi-specialty
societies.
The development of options for validating the Harvard and
RUC physician procedure time data.
The evaluation of the indirect cost allocation
methodology.
The development of options for the five-year review of
practice expense RVUs.
We intend to keep the medical community informed about all of these
activities and to seek their input.

SMS Data

Background

We received comments from a large number of medical specialty
societies, both on our June 1998 proposed rule and our November 2, 1998
final rule, which expressed concern that their specialty or
subspecialty was not adequately represented in the SMS survey data used
to compute their practice expense per hour. In addition, several
specialties, primarily nonphysician groups, were not included in the
SMS data, making it necessary for us to crosswalk their practice
expense per hour to an included specialty. A large number of these
specialties either have submitted supplementary data or have expressed
a desire to collect new data that they believe would more accurately
reflect the practice expense per hour for their specialty.
While we appreciate the effort that these organizations have
expended or are willing to expend, we are not yet in a position to use
this supplementary or new data in our practice expense calculations. It
is important to understand that, given the budget neutrality
restrictions under which we are working, any increase in one
specialty's practice expense pool will lead to a decrease for other
specialties. Therefore, until we have developed reliable and
standardized criteria for accepting and validating additional
specialty-specific data, it would be inequitable to make any
significant changes based on these data.
We recognize that this delay in indicating what additional data
would be acceptable might be frustrating to those groups that believe
that the SMS data does not accurately account for all of their costs.
For that reason, we are ensuring that a priority of the technical
contractor discussed above is to determine (1) the circumstances, if
any, under which we should consider use of survey data other than the
SMS data; (2) the appropriate form of these surveys; and (3) how these
surveys or future SMS surveys can be appropriately validated for our
use. We hope to be in a position to discuss this in more detail in the
final rule to be published this fall.
Adjustment to Direct Patient Care Hours for Pathology
In the November 1998 final rule, we made adjustments to the direct
patient care hours for pathologists to account for the fact that the
time spent performing autopsies and supervising technicians are Part A
services. The pathologists, supported by the AMA, also requested that
we eliminate some of the time for ``personally performing nonsurgical
laboratory procedures including reports'' because this time also
includes some Part A services. We did not make this latter adjustment
in the final rule because we did not have the data on what precise
adjustment to make. We now have information to propose this adjustment
as well. The SMS survey shows that pathologists reported 6.77 hours per
week in personally performing nonsurgical laboratory procedures
including time writing reports. The College of American Pathologists
recommended that 45 percent of the 6.77 hours, which represents three
hours, be removed from total patient care hours. The pathologists argue
that they are providing specific services to attending physicians, but
we will not allow separate payment because the attending physician does
not request a consultation. This problem is unique to this specialty
and, as this change will have no discernible negative impact on any
other specialty, we are proposing to remove these three hours from the
total patient care hours for pathologists.

CPEP Data

RUC Recommendations
As we stated above, the PEAC is beginning to review the procedure-
specific CPEP inputs. Because most major physician specialties are
represented on the PEAC and they will determine which codes are
discussed at each meeting, we plan to wait until we receive
recommendations from the RUC before making significant changes to most
code-specific inputs. However, there are a number of egregious errors
or anomalies that were pointed out in the public comments we received
on the June 1998 proposed rule and the November 1998 final rule that we
intend to address in the final rule this fall.

Physicians' Clinical Staff in the Facility Setting

In some of the original CPEP panels and in subsequent meetings,
various specialties have argued that the physician's own clinical staff
performs certain services for a hospital patient. In our initial
``bottom-up'' practice expense proposal in the June 1997 proposed rule,
we edited out all of the clinical staff time in the facility setting.
It was our contention then, and still is now, that Medicare already
pays for services performed for a facility patient through some other
mechanism, that these services are not typically performed by a
physician's own staff and that recognizing these inputs is arguably
inconsistent with the law and with our regulations. However, in our
1998 ``top-down'' proposal we used the raw CPEP inputs without applying
edits to any of the data, and the clinical staff time in the facility
setting was therefore included.
We are proposing to exclude from the raw CPEP data all staff time
allotted to the use of clinical staff in the facility setting. This
CPEP data is used in our methodology solely to allocate the specialty-
specific practice expense pools to the individual codes. We would not
make an adjustment to the SMS data because we cannot separately
identify the costs related to physicians' clinical staff time in
hospitals and we do not believe that these costs are typically
incurred. We propose to make this adjustment now before extensive
refinement efforts are undertaken. We are also soliciting comments,
information and data regarding situations where the recognition of
costs associated with the use of a physician's clinical staff in a
facility would be appropriate. We will consider these responses for the
final rule.
There are several arguments to be made for excluding the costs of
clinical staff in the facility setting from the raw CPEP data used in
calculating the practice expense payment for any service:
1. Medicare should not pay twice for the same service.
Many specialties argue that their clinical staff performs various
duties for the hospital patient, examples of which are presented below;
all these and other facility clinical staff services are already paid
for by Medicare through a mechanism other than physician practice
expense.

--Assistant at Surgery--Medicare will make a separate payment for a
physician assistant, nurse practitioner or clinical nurse specialist
acting as assistant at surgery. Therefore, their

[[Page 39618]]

time cannot also be counted as a practice expense input in the CPEP
data.
--Scrub Nurse--Medicare already pays the hospital for all nursing
services provided to a hospital patient, including scrub nurse
services, either through the DRG payment or on a cost basis.
--Monitoring Patients Undergoing Conscious Sedation--In order to meet
accreditation standards, all hospitals must already have staff
available to monitor these patients. Medicare pays the hospital for
this service or makes separate payment for a certified registered nurse
anesthetist. To include staff time in the CPEP data for this service
would result in a duplicate payment.
--Reviewing Charts, Making Patient Rounds, Pulling Chest Tubes--These
activities are physicians' services that are paid for through the
physician work RVUs. Physicians may choose to delegate some of their
work to their clinical staff. However, unless the work RVUs are
commensurately reduced, it would be inappropriate to also include this
staff time in the practice expense calculations.
--Making Phone Calls from the Physician's Office--Phone calls
concerning the patient made to the family or the facility are
considered an administrative cost. The staff time for these services is
paid for under our indirect practice expense allocation.

Unless we were to reduce the DRG payment made to hospitals or the
work RVUs used to determine physician payment, the inclusion of the
costs of any of this clinical staff time in the calculation of
procedure-specific practice expenses would essentially lead to a
duplication of Medicare payment. We welcome comments from hospitals,
physicians, and others on this issue.
2. It is not a typical practice for most specialties to use their
own staff in the facility setting.
While physician practice patterns may vary by specialty, by
practice size and configuration and by individual practitioner, we pay
only one rate, with the exception of a geographic adjuster, for a given
site for any specific service. Therefore, the CPEP inputs for each
service cannot reflect all variations in practice patterns, but are
rather meant to represent the clinical staff times, supplies, and
equipment that are used for the typical patient receiving that service.
We have not seen sufficient data to convince us that the use of the
physician's clinical staff in the facility setting is a typical
practice. The American Hospital Association performed a survey of a
sample of their members which indicated that this practice occurred
only occasionally. Because we do not believe that physicians typically
incur costs for bringing their staff into the facility setting, the
aggregate SMS data should contain few costs for such services.
Therefore, we are not proposing to eliminate any clinical staff
expenses from the surgical specialties' aggregate SMS practice expense
data.
3. Inclusion of these costs is arguably inconsistent with both the
law and Medicare regulations.

--Section 1862(a)(14) of the Act, which discusses exclusions from
coverage, states that,

``Notwithstanding any other provision of this title, no payment may
be made under part A or part B * * * for any expenses incurred for
items or services which are other than physicians' services (as defined
in regulations promulgated specifically for purposes of this paragraph)
* * * and which are furnished to an individual who is a patient of a
hospital * * * by an entity other than the hospital * * * unless the
services are furnished under arrangements. * * *''

(This section also exempts services of physician assistants, nurse
practitioners, clinical nurse specialists, certified nurse-midwife
services, qualified psychologist services, and services of certified
registered nurse anesthetists from the above exclusion.)

--In Sec. 411.15, (Particular Services Excluded from Coverage)
subparagraph (m)(1), we paraphrase the above provision for hospital
inpatients and add that ``services subject to exclusion under this
paragraph include * * * services incident to physicians' services.''
Section 411.15(m)(2) implements the exceptions to this exclusion, among
them ``physician services that meet the criteria of Sec. 415.102(a) of
this chapter for payment on a reasonable charge or fee schedule
basis.''
--Section 415.102(a) contains the definition of physicians' services
required by section 1862(a)(14) of the Act and the criteria referred to
in Sec. 411.15(m) above: ``If the physician furnishes services to
beneficiaries in providers, the carrier pays on a fee schedule basis
provided the following requirements are met: (1) The services are
personally furnished for an individual beneficiary by a physician. (2)
The services contribute directly to the diagnosis or treatment of an
individual beneficiary. (3) The services ordinarily require performance
by a physician.''
--On September 8, 1998, we published a proposed rule on a prospective
payment system for hospital outpatient services (63 FR 47552). This
rule proposes to add Sec. 410.39 which embodies in regulation for the
hospital outpatient setting the exclusion in Sec. 411.15 described
above. Section 410.39(c) would exempt from the exclusion physicians'
services that meet the requirements of Sec. 415.102(a) as described
above, physician assistant, nurse practitioner, clinical nurse
specialist, certified nurse midwife, and qualified psychologist
services, as well as services of an anesthetist.

A reading of all of the above suggests that no payment should be
made under the physician fee schedule for the costs of physicians'
clinical staff used in the hospital setting. Services performed by non-
physician clinical staff do not fulfill the definition of services
personally furnished by a physician, and, therefore, the exception to
the exclusion created by section 1862(a)(14) of the Act does not apply.
In addition, nursing services, such as those performed by a scrub nurse
working for a physician, do not ordinarily require performance by a
physician and, thus, are not physicians' services for the purpose of
section 1862(a)(14) of the Act. Finally, services ``incident to a
physician's service'' are explicitly excluded from coverage in the
hospital setting by Sec. 411.15(m)(1).
Table 5, ``Impact on Total Allowed Charges by Specialty of
Excluding the Cost of Clinical Staff in the Facility Setting,'' shows
the impact of the proposed changes on each major specialty's total
allowed charges. As can be seen from this table, anesthesia and cardiac
surgery face a decrease of 8 percent over the transition period, while
thoracic surgery has a decrease of 6 percent over the same period. No
other specialty has a decrease of more than 2 percent. The increases
are spread throughout the specialties, with rheumatology standing to
gain the most with a 5 percent increase, followed by orthopedic
surgery, obstetrics and gynecology and podiatry each with a 3 percent
increase.
It is not surprising that the practice expenses for cardiac and
thoracic surgery and anesthesiology would decrease if clinical staff in
the facility is excluded given the clinical staff time in the CPEP
data. The raw CPEP data for the cardiac and thoracic codes contain up
to 57 hours of clinical staff time in the hospital for a given
procedure. For example, the total facility clinical staff

[[Page 39619]]

time of 24 hours for CPT code 33771 (repair of great vessels defect)
includes nearly seven hours for a physician assistant to act as
assistant at surgery, which can be billed separately, and over six
hours for a scrub nurse that we pay the hospital to provide.
The anesthesia CPEP panel also added inputs of up to 195 minutes
clinical staff time per procedure in the facility setting, which is
particularly inexplicable for such a hospital-based specialty. This
time is divided between a registered nurse, physician assistant, and an
anesthesia technician. It is in no way clear for what purposes an
anesthesiologist would employ a nurse or a physician assistant, but in
any case we pay the hospital for all nursing care and we make separate
payment for a physician assistant.
We welcome comments on this entire issue and particularly solicit
information about any possible appropriate use of physicians' clinical
staff in the facility setting that we should consider for our final
rule.

Physician Time

Background

Under the ``top down'' methodology we are using to calculate the
resource-based practice expense for physicians' services, the physician
time attributed to each service has now become a significant factor in
determining the RVUs assigned to that service. Therefore, it is vital
that there is confidence in the accuracy of these times. As we
discussed above, we have a contract to assist us in resolving many of
the outstanding methodological issues we face in refining our ``top
down'' approach. One of the tasks this contractor will undertake is to
develop options for validating the 1992 Harvard research team study and
the AMA/RUC physician time data.
Pediatric Surgery Physician Time Data
In its comments on the June 1998 proposed rule, the American
College of Surgeons stated that the physician time assigned to
pediatric surgery codes was based on erroneously low physician time
data from the original Harvard study, rather than on later data from
the study of pediatric services performed by the same Harvard study
team for the American Pediatric Surgical Association in 1992. The
comment further stated that the latter data were used as the basis for
the work RVUs assigned to these 48 pediatric surgical services. We
responded in the final rule that such inaccuracies in the physician
time data would be considered during the refinement process. We are
currently analyzing the data needed to make the appropriate corrections
and will update the physician times for these 48 pediatric surgical
services in the final rule.
Physical Therapy and Occupational Therapy Times
In the November 1998 final rule we did not use the RUC physician
time data for the physical therapy codes (CPT 97001 through 97770) as
we believed these times to be inaccurate. Instead, we set the time for
these procedures using the judgment of our clinical staff. In its
comments on the final rule, the American Physical Therapy Association
(APTA) stated that the times that we used were too low because it
appeared that we used only intra-service time. The American
Occupational Therapy Association, in its comments on the proposed rule,
also objected to our reduction in times for outpatient rehabilitation
codes. While APTA conceded that the RUC survey data on the times for
these services could cause confusion, APTA also argued that we should
recognize some preservice and postservice times for physical therapy
services. APTA made specific recommendations that included such
preservice and postservice times, while acknowledging that, because
multiple procedures are often performed at the same session, there
could be overlap in these times. We agree that it is appropriate to
include some preservice and postservice times for these procedures and
have adjusted the total code-specific times used to create the practice
expense pools as shown in Table 6, ``Revised Times for CPT codes 97001
through 97770.''

RUC Time Database
The primary sources for the physician time data used in creating
the specialty-specific practice expense pools are the surveys done for
the initial establishment of the work RVUs and the surveys submitted to
the AMA's RUC. We have been informed by the AMA that some of the RUC
times we used for the November 1998 final rule differed from the times
found in the official RUC database. The AMA also conveyed to us that
the RUC is currently verifying their database with the relevant
specialties and plans to send it to us in time for its use in the final
rule.

Crosswalk Issues

Physical and Occupational Therapy Indirect Costs
We currently crosswalk physical and occupational therapy services
to the ``all physician'' practice expense per hour for direct costs.
However, for indirect costs we believed that the crosswalk to ``all
physicians'' would overstate the actual practice expense for therapy
services. Instead we used the data used to develop the therapy salary
equivalency guidelines to create the practice expense per hour for
these costs. These guidelines, which were developed for therapists
working under contract for a facility, assume a required space of 250
square feet per therapist. Organizations representing both physical and
occupational therapists objected that this estimate of 250 square feet
was insufficient to reflect expenses for therapists in private
practice. After further consideration of these comments and after
consultation with industry representatives, we agree that these space
requirements may not be representative of the actual space needed by
independent therapists. Based on our analysis of the available data, we
have increased the space requirements to 500 square feet.
Vascular Surgery
The SMS survey sample of 10 vascular surgeons is too small for us
to calculate accurately a practice expense per hour for this specialty.
In the 1998 proposed and final rules, we combined their data with that
of the cardiac and thoracic surgeons to create a combined practice
expense pool for all three specialties. The Society for Vascular
Surgery commented that this crosswalk understated the actual practice
expense for their specialty because vascular surgery services generally
involved patients with more co-morbidities, included more evaluation
and management services and thus were more office-based. We agree that
the current crosswalk might not appropriately approximate the
specialty's costs, and we are proposing to change vascular surgery's
crosswalk to the ``all physician'' practice expense per hour.
Calculation of Practice Expense Pools--Other Issues
In the November 2, 1998 final rule, in response to the many
commenters that objected to the reductions published in the June 5,
1998 proposed rule for services with no work RVUS, we created, as an
interim solution, a separate practice expense pool for all services
with zero work RVUs. We used the ``all physicians'' category for the
practice expense per hour for this pool and, instead of allocating this
pool by the CPEP data, we used the 1998 RVUs as the allocator.
This was of benefit to most of the services included in this
expense pool, but some specialties, such as sleep medicine, neurology,
ophthalmology, and pathology that had not commented on problems with
their services with no work RVUs were negatively affected by this
methodological change relative to the June 5, 1998 proposal. We have
subsequently received comments from societies for these specialties
requesting that these services be taken out of this special pool and be
treated like the vast majority of codes. As many of these services are
provided by other specialties as well and such a change could have an
impact across specialties, we are seeking comments both on such an
adjustment in general and on specific services that should either be
included or excluded from the adjustment. However, if we do remove
codes from the zero work RVU pool in our final rule, we plan to do it
in a uniform manner across families or categories of codes, instead of
allowing individual services to be placed in or out of the ``zero work
RVU'' practice expense pool depending on which method yields the
highest RVUs.
Table 7, ``Approximate Additional Changes in the Practice Expense
RVUs for Codes That Might Be Removed from the Zero Work Pool,'' shows
the list of codes that we are considering removing from the ``zero work
RVU'' pool, and Table 8, ``Additional Impact on Total Allowed Charges
by Specialty of Removing Selected Codes from the Zero Work Pool,''
shows the impact of this change by specialty.

Site-of-Service Differential

Clarification of Site-of-Service Policy
We wish to clarify the circumstances under which either the non-
facility or facility RVUs are used to calculate payment for a service.
In the November 2, 1998 final rule, we defined hospitals, skilled
nursing facilities (SNFs), and ambulatory surgical centers (ASCs) as
facilities for practice expense purposes. For the purposes of the
physician practice expense calculation, all other sites-of-service are
considered non-facility. The distinction between the non-facility and
facility setting takes into account the higher expenses of the
practitioner in the non-facility setting, where the practitioner
typically bears the cost of the resources--clinical staff, supplies,
and equipment--associated with the service.
The major purpose of the site-of-service distinction is to ensure
that Medicare does not make a duplicate payment for any of the practice
expenses incurred in performing a service for a Medicare patient. When
the beneficiary is a hospital, SNF, or ASC patient, the facility itself
is paid for the clinical staff, supplies, and equipment needed to take
care of that patient, and the lower facility rate should be paid to the
practitioner. Therefore, if the patient is a facility patient or a
facility will bill for the service, the practitioner must bill using
the facility site-of-service designation. We are modifying the language
in Sec. 414.22(b)(5)(i) in order to clarify this policy. There are also
three further clarifications that need to be made with respect to this
policy.
(1) When a procedure is performed in an ASC that is not on the
Medicare approved list of ASC procedures, we do

[[Page 39623]]

not make a facility payment to the ASC. In this situation, the ASC is
considered a physician's office and the non-facility RVUs would be
used.
(2) Because of the hospital bundling requirement, only the hospital
can bill for therapy services provided to hospital patients. In
addition, through PM-AB-98-63, ``Prospective Payment System for
Outpatient Rehabilitation Services and Application of Financial
Limitations,'' dated October 1998 and our final rule of November 2,
1998, we advised our fiscal intermediaries to require SNFs to bill
Medicare directly for all outpatient therapy services provided to their
SNF residents in a noncovered Part A stay and to their nonresidents
covered under Part B. Because only the facility can bill for therapy
services provided to hospital and SNF patients, the payment for the
full practice expense must be reflected in the facility payment.
Therefore, the higher non-facility RVUs are used to pay for therapy
services even in the facility setting.
(3) While a SNF is considered a facility, a nursing home is not.
Many are mixed facilities with a combination of nursing home and SNF
patients. Practitioners, such as podiatrists, have commented that it is
not always easy to determine into which category the patient falls. We
are clarifying our policy to state that practitioners, such as
podiatrists, should designate their service as a facility service,
unless they verify that no Part A claim will be made for the service,
in which case the ``non-facility'' designation can be used. However, we
note that there might be lower per patient costs in a mixed facility or
a nursing home setting, where multiple patients can be seen in a single
visit to the site, than in the office setting. We welcome comments on
ways to examine the relative costs of treating patients in these
different settings, so that we can determine whether an adjustment to
certain non-facility practice expense payments is appropriate.
Limitation on Facility RVUs
The non-facility RVUs would be expected to be higher than the
facility RVUs for a given service, because the practitioner bears the
costs of the necessary clinical staff, supplies, and equipment. Because
of anomalies in our calculations, generally due to the different mix of
specialties delivering the service in the two settings, for some codes
the facility RVUs are higher than the non-facility RVUs. We are
proposing to limit the facility rate so that it cannot be higher than
the non-facility rate for any given code. Because of budget neutrality,
any decrease in the facility RVUs will be offset by a corresponding
increase in RVUs spread throughout the physician fee schedule. This
change has negligible impact on any specialty.

C. Practice Expense Relative Value Units for a Physician's
Interpretation of Abnormal Papanicolaou Smears

In the November 1998 final rule (63 FR 58814), we revised the codes
for a physician's interpretation of an abnormal Papanicolaou (Pap)
smear to include three HCPCS level II codes (P3001, G0124, and G0141)
in addition to the CPT code 88141. We included the HCPCS level II codes
to accommodate differences in Pap smear technology. We evaluated the
practice expense RVUs for each of these three codes in a slightly
different manner for the 1999 physician fee schedule. We now believe
that it would be more appropriate to evaluate the work, practice
expense, and malpractice RVUs for these codes identically and
comparable to the values for CPT code 88141. We are proposing to make
the practice expense RVUs identical for these codes since there are no
significant differences between them.

D. Physician Pathology Services and Independent Laboratories

Physician pathology services consist of a technical component and a
professional component. The technical component refers to the slide
preparation, staining, and other duties performed by the laboratory
technologist. The professional component refers to the physician's
interpretation.
A hospital laboratory may furnish the technical component of the
physician pathology service directly to its patients or it may have an
independent laboratory furnish the service. Before the implementation
of the hospital inpatient prospective payment system (PPS), the
independent laboratory had two payment options:
It could make an arrangement with the hospital and have
the hospital bill the intermediary, and the hospital could be paid on a
reasonable cost basis for the service.
It could bill the carrier directly for the service and be
paid on a reasonable charge basis.
In most cases, the independent laboratory furnished a service that
combined the technical and professional components and billed the
carrier for the complete physician pathology service.
When developing PPS, we considered requiring the hospital to
include in its costs the technical component of the physician pathology
service to a patient by an independent laboratory. This would have been
consistent with our general policy of including the cost of hospital
services to hospital inpatients by outside suppliers in the diagnosis-
related group (DRG) payment. Instead, we decided to allow the
independent laboratory to continue to bill the carrier for the complete
service. The rationale, based on discussions with the College of
American Pathologists, was that the technical component was an
incidental service to the physician pathology service. At that time it
was not treated as a service in and of itself, and the independent
laboratory usually billed for the complete service. It was believed
that requiring the separation and identification of the technical
component service would have been disruptive to traditional billing
practices for independent laboratories.
When PPS began, hospitals that furnished the technical component of
the physician pathology service directly included that cost in their
base period cost report. This cost was used to calculate the
standardized amounts that are the basis for payment under PPS.
Therefore, hospitals are paid for providing the technical component of
the service through the standardized amounts. It was our understanding
that most hospital laboratories furnished the technical component
service directly to its patients. Even though the hospital that
contracted out its physician pathology services did not include any of
the cost of technical component services in its base period cost, when
PPS was fully implemented, this hospital would have been paid the same
PPS rate as that paid to other hospitals that had included technical
component costs.
Currently, under the physician fee schedule, an independent
laboratory can bill and receive payment for the technical component of
physician pathology services for a hospital inpatient. We believe this
is in conflict with the hospital rebundling provision in section
1862(a)(14) of the Act and has created a perverse incentive for the
type of activity that the bundling provision was intended to prevent.
Based on the way PPS rates are constructed, we believe that we are
paying for the technical component twice; once to the hospital through
the PPS payment and again to the independent laboratory through the
physician fee schedule.
Generally, historically larger hospitals used independent
laboratories on an ``as needed'' basis and smaller hospitals contracted
with independent laboratories for their physician pathology service.
Recently, though, we have become aware that more hospitals are
considering contracting their in-

[[Page 39624]]

house technical component physician pathology services to an outside
laboratory if our policy remained unchanged. The hospital could
continue to be paid for the technical component service under the PPS,
and the independent laboratory could bill its carrier for the same TC
under the physician fee schedule.
Because we believe that a hospital patient's technical component is
already included in payment under PPS, we are proposing to revise our
regulations to end payments to independent laboratories under the
physician fee schedule for technical component services furnished to
hospital inpatients. Specifically, we propose to revise Sec. 415.130(c)
to state that, after December 31, 1999, we would only pay hospitals for
their inpatients' technical component services.
Section 4104(c) of OBRA 1990 (Public Law 101-508) instructed HCFA,
in establishing ancillary policies under the physician fee schedule, to
``consider an appropriate adjustment to reflect the technical component
of furnishing physician pathology services through a laboratory that is
independent of a hospital and separate from an attending or consulting
physician's office.'' We considered this issue when we implemented the
physician fee schedule and established a separate payment for the
technical component of physician pathology services furnished both to
hospital patients and non-hospital patients.
However, we have now reconsidered this policy with respect to
hospital inpatients because it seems inconsistent with the hospital
rebundling provision and we believe it creates an incentive to shift
the location where the services are provided, thereby conflicting with
the purpose of the hospital rebundling provision. We have anecdotal
information that hospitals are having a pathologist establish an
``independent'' laboratory near the hospital, intending that the new
laboratory perform the technical components of physician pathology
services and bill for those technical components and that there would
be no reduction in PPS payment to the hospital. We believe our proposal
is necessary in order for Medicare to avoid making double payment in
such circumstances. We believe that the language of section 4104(c) of
OBRA 1990 provides sufficient authority for us to determine that, in
the case of hospital patients, it is not appropriate for us to provide
for independent laboratories to bill the TC of pathology services
directly.
Under our proposal, independent laboratories would still be able to
bill and receive payment from their Medicare carrier for the technical
component of a physician pathology service furnished to beneficiaries
who are not hospital inpatients. For the technical component of
physician pathology services provided by an independent laboratory to a
hospital inpatient, the independent laboratory would have to make
arrangements with a hospital to receive payment.
The physician fee schedule regulations would continue to allow the
independent laboratory to bill and receive payment under the physician
fee schedule for the technical component of physician pathology
services to hospital outpatients. Of course, the hospital could, if it
chose instead, make an arrangement with the independent laboratory and
be paid on a reasonable cost basis for this service. However, payment
is made under only one method and only to one of these entities.
Since we will be publishing final regulations to implement the
outpatient prospective payment system and have received comments and
concerns about the outpatient technical component of physician
pathology services, we will address that issue in context of those
regulations.

E. Discontinuous Anesthesia Time

Payment for anesthesia services is based on the sum of base units
plus time units multiplied by a locality-specific anesthesia conversion
factor. Under the current regulations at Sec. 414.46(a)(1) (Additional
rules for payment of anesthesia services), the base unit is the value
for each anesthesia code reflecting all activities other than
anesthesia time. These activities include preoperative and
postoperative visits, the administration of fluids or blood incident to
anesthesia care, and monitoring services.
Anesthesia time, as defined under Sec. 414.46(a)(2), starts when
the anesthesiologist or certified register nurse anesthetist (CRNA)
begins to prepare the patient for anesthesia care and ends when the
anesthesiologist or CRNA is no longer in personal attendance; that is,
when the patient may be placed safely under postoperative care. Time
units are computed by the carrier based on the reported anesthesia
time. (For purposes of this section and as described in section
1861(bb) of the Act, the term CRNA includes an anesthesiologist
assistant (AA)).
In the normal course of the administration of an anesthetic, the
following events occur:
Establishment of venous access.
Acquisition of initial monitoring information (blood
pressure, oximetry, electrocardiogram).
Induction of anesthesia (general, regional, block,
monitored anesthesia care).
Maintenance of anesthesia during the surgical procedure.
Conclusion of anesthesia attendance.
In many situations, once the anesthesiologist or CRNA is in
attendance he or she remains continuously with the patient for all five
events. This represents continuous anesthesia time.
There may be instances, however, when there is a break in the
continuous presence of the anesthesiologist or CRNA in the events
listed above. Discontinuous anesthesia time could occur when a regional
or block technique is used, resulting in a break between the induction
of the anesthesia and the maintenance of the anesthesia. For example, a
patient may receive an upper extremity block for hand or arm surgery in
a location other than the operating room, and there may be a time
period following the start of the anesthetic and prior to moving the
patient to the operating room during which the patient can be safely
observed by non-anesthesia personnel.
A break in anesthesia time could also occur between the periods
when the anesthesiologist or CRNA obtains initial monitoring
information and induces anesthesia. This usually occurs when a patient
is being prepared in the operating room for induction of anesthesia
and, for some reason, the surgeon is delayed or unavailable. In this
instance, the anesthesiologist or CRNA may leave the patient under the
observation of the operating room nurse until it is appropriate to
proceed with the induction of the anesthesia.
Discontinuous anesthesia time could also occur in facilities that
use anesthesia ``induction'' rooms where anesthesiologists or CRNAs may
start IVs, thereby increasing efficiency in the use of operating room
time. In these cases, there could be breaks at any point in the time
periods between the establishment of the venous access, acquisition of
the initial monitoring information, and induction of the anesthesia.
We are proposing to revise our regulations to allow
anesthesiologists and CRNAs to sum up blocks of time around a break in
continuous anesthesia care as long as there is continuous monitoring of
the patient within the blocks of time. We propose to revise our
regulations in Sec. 414.46 to include this exception to the general
requirement.

[[Page 39625]]

The current regulations on anesthesia time units refer to
anesthesiologists and medically-directed CRNAs. However, the
calculation of anesthesia time units also applies to claims for
services submitted by CRNAs who are not medically-directed. Thus, we
are proposing to revise the regulation text at Sec. 414.60 (Payment for
the services of CRNAs) to clarify this issue. These revisions are
necessary to link the payment methodology for CRNA services to the
payment methodology for physician anesthesia services.
These revisions would not alter the fundamental principle that
anesthesia time represents a continuous block of time when a patient is
under the care of an anesthesiologist or CRNA. Nor would this proposal
alter our policy that an anesthesiologist or CRNA may not bill time
units for the pre-anesthesia examination and evaluation; these services
will continue to be included as part of the base unit component.

F. Optometrist Services

Before 1987, the services of optometrists were covered only if
related to the condition of aphakia. Effective April 1, 1987, section
9336 of the Omnibus Budget Reconciliation Act of 1986 (OBRA 1986)
(Public Law 99-509), enacted on October 21, 1986, amended section
1861(r)(4) of the Act to expand coverage of optometrists services.
Thus, coverage has been expanded to include services otherwise covered
by Medicare that an optometrist is legally authorized to perform as a
doctor of optometry by the State in which the optometrist performs
them.
We are conforming Sec. 410.23 (Limitations on services of an
optometrist) of the regulations to be consistent with the statutory
provision that has been implemented through manual provisions. The
regulations would specify that Medicare Part B pays for the services of
a doctor of optometry, acting within the scope of his or her license,
if the services would be covered as physicians' services when performed
by a doctor of medicine or osteopathy.

G. Assisted Suicide

Section 9 of Public Law 105-12 (The Assisted Suicide Funding
Restriction Act of 1997) added section 1862(a)(16) of the Act. Public
Law 105-12 prohibits the use of Federal funds to furnish or pay for any
health care service or health benefit coverage for the purpose of
causing, or assisting to cause, the death of any individual. The
prohibition does not apply to withholding or withdrawing medical
treatment, nutrition, or hydration. In addition, the prohibition does
not apply to furnishing a service to alleviate pain, even if doing so
may increase the risk of death, as long as the purpose is not to cause
or assist in causing death. The list of programs to which
