Medicare Hospital And Physician Payments: 

Geographic Cost Adjustments Important to Preserve Beneficiary
Access to Services: 

Statement of William J. Scanlon: 
Director, Health Care Issues: 

GAO-02-968T: 

Madam Chairman and Members of the Subcommittee: 

I am pleased to be here today as you discuss how the Medicare program 
adjusts payments to hospitals and physicians to account for geographic 
differences in costs. Because Medicare's hospital and physician 
payment systems are based on national rates, these geographic cost 
adjustments are essential to account for costs beyond providers' 
control and to ensure that beneficiaries have adequate access to 
services. If these adjustments are not adequate, Medicare could 
financially reward or penalize providers due only to where they are 
located. Over time, this could affect some providers' financial 
stability and their ability or willingness to continue serving 
Medicare patients. 

Some providers contend that Medicare's geographic cost adjustments are 
inadequate. Medicare's payments to hospitals are intended to vary with 
the average wages paid in a hospital's labor market. Yet, some 
hospitals believe that the labor cost adjustment applied to their 
payments does not reflect the average wage they face in their labor 
market area. Hospitals that meet certain criteria can qualify to have 
their payments increased through Medicare's reclassification process. 
But concerns remain about the geographic variation in payments to 
hospitals and disparities in hospital financial performance under 
Medicare's hospital payment system. Similarly, physicians have raised 
concerns about the appropriateness of Medicare's geographic adjustment 
to their fees. 

My comments today are based on our forthcoming report on the Medicare 
program's labor cost adjustment for hospital services and our 
preliminary work on the program's physician payment adjustment. I will 
focus on (1) how Medicare determines the labor cost adjustment for 
hospitals in an area; (2) whether Medicare's labor cost adjustment 
accounts appropriately for geographic variation in wages paid by 
hospitals; (3) the extent to which geographic reclassification 
addresses potential problems with Medicare's labor cost adjustment for 
hospitals; and (4) how Medicare determines geographic adjustments to 
physician fees. My comments are based primarily on our analysis of 
hospital Medicare cost report data and other information, including 
that compiled by the Centers for Medicare and Medicaid Services, the 
agency within the Department of Health and Human Services that 
oversees the Medicare program. 

In summary, Medicare's labor cost adjustment does not adequately 
account for geographic differences in hospital wages in some areas 
because a single adjustment is applied to all hospitals in an area 
even though the area may encompass multiple labor markets or different 
types of communities within which hospitals pay significantly 
different average wages. Geographic reclassification addresses some 
inequities in Medicare's labor cost adjustments by allowing some 
hospitals that pay wages enough above the average in their area to 
receive a higher labor cost adjustment. At the same time, however, 
some hospitals can reclassify even though they pay wages that are 
comparable to the average in their area. To help ensure that 
beneficiaries in all parts of the country have access to services, 
Medicare adjustments its physician fee schedule based on indexes 
designed to reflect cost differences among 92 geographic areas. The 
adjustment is designed to help ensure that the fees paid in a 
geographic area appropriately reflect the cost of living in that area 
and the costs of operating a practice. We are beginning an analysis of 
the methodology and data that Medicare uses to make the adjustment to 
determine whether it appropriately reflects underlying costs and, if 
not, whether beneficiary access to physician services has been 
impaired in certain areas. 

A Hospital's Labor Cost Adjustment Is Based On Average Wages Paid in a 
Geographic Area: 

Medicare's prospective payment system (PPS) provides incentives for 
hospitals to operate efficiently by paying them a predetermined, fixed 
amount for each inpatient hospital stay, regardless of the actual 
costs incurred in providing the care. Although the fixed, or 
standardized, amount is based on national average costs, actual 
hospital payments vary widely across hospitals, primarily because of 
two payment adjustments in PPS. There is an adjustment that accounts 
for cost differences across patients due to their care needs, and a 
labor cost adjustment that accounts for the substantial variation in 
average hospital wages across the country. The fixed amount is 
adjusted for these two sources of cost differences because they are 
largely beyond any individual hospital's ability to control.
The Medicare labor cost adjustment for a geographic area is based on a 
wage index that is computed using data that hospitals submit to 
Medicare. The wage index for an area is the ratio of the average 
hourly hospital wage in the area compared to the national average 
hourly hospital wage. The wage indexes ranged from roughly 0.74 to 1.5 
in 2001.[Footnote 1] Only the portion of the hospital payment that 
reflects labor-related expenses (71 percent) is multiplied by the wage 
index. The rest of the payment, which covers drugs, medical supplies 
and certain other non-labor-related expenses, is uniform nationwide 
because prices for these items are not perceived as varying 
significantly from area to area.[Footnote 2] 

The geographic area for which a wage index is calculated is supposed 
to represent an area where hospitals pay relatively uniform wages. If 
it does not, the hospitals in the area may receive a labor cost 
adjustment that is higher or lower than the wages paid in their area 
would justify.[Footnote 3] 

The Medicare program uses the Office of Management and Budget's (OMB) 
"metropolitan/non-metropolitan" classification system to define the 
geographic areas used for the labor cost adjustment. Medicare 
calculates labor cost adjustments for 324 metropolitan areas and 49 
"statewide" non-metropolitan areas. Medicare specifies an OMB 
metropolitan statistical area (MSA) as a distinct region within which 
wages are assumed to be relatively uniform.[Footnote 4] Medicare 
specifies the rest of a state-—all the non-MSA counties[Footnote 5]-—
as a single, non-metropolitan area in which hospitals are assumed to 
face similar average wages. These non-metropolitan areas can be quite 
large and not contiguous (see figure 1).

Labor Cost Adjustment Does Not Adequately Account for Wage Differences 
Within Certain Areas: 

The variation in hospital wages within some Medicare geographic areas -
MSAs or the non-metropolitan areas in a state—is systematic across 
different parts of these areas. While wages paid by hospitals are 
expected to vary within a labor market, such systematic variation 
suggests that some Medicare geographic areas include multiple labor 
markets within which hospitals pay different average wages. For 
example, average hospital wages in outlying counties of MSAs tend to 
be lower than average hospital wages in central counties. Average 
wages in non-metropolitan large towns tend to be higher than in other 
non-metropolitan areas within a state. Because the labor cost 
adjustment does not take this kind of systematic variation into 
account, the adjustment sometimes does not appropriately reflect the 
average wages that hospitals pay. 

Medicare Metropolitan Geographic Areas May Encompass Multiple Labor 
Markets With Varying Average Wages: 

Because an MSA may extend over several thousand square miles, the 
hospitals within an MSA may not be competing with each other for the 
same pool of employees. Therefore, these hospitals may need to pay 
varying wages to attract workers. The Washington, D.C. MSA illustrates 
how hospital wages in a large MSA can vary across different counties 
(see figure 2). It includes hospitals located in the central city of 
the District of Columbia and in 18 counties in Maryland, Virginia, and 
West Virginia. Hospital wages averaged $23.70 per hour in fiscal year 
1997 in the District of Columbia and in most adjacent suburban 
Maryland and Virginia counties, but averaged $20.14 per hour in the 
outlying counties. Yet, the labor cost adjustment for hospitals within 
this MSA is based on an average wage of $23.41 per hour and is the 
same for hospitals within all its counties.

Hospitals in central counties of an MSA typically pay higher wages 
than hospitals in outlying counties. Central county hospital wages 
ranged from 7 percent higher than outlying county hospital wages in 
Houston to 38 percent higher in New York City in fiscal year 1997. In 
most of the MSAs with the highest population, the difference was from 
11 to 18 percent in fiscal year 1997. 

Some Medicare Non-metropolitan Geographic Areas Encompass Multiple 
Community Types with Varying Wages: 

Medicare uses the same labor cost adjustment for all hospitals in the 
non-metropolitan areas of a state. The adjustment would be adequate 
for all hospitals in these sometimes vast areas if the hospitals paid 
similar average wages. However, we found wage variation across non-
metropolitan areas that appears to be systematically related to type 
of community. In three-quarters of all states, the average wages paid 
by hospitals in large towns are higher than those paid by hospitals in 
small towns or rural areas. About 38 percent of hospitals in large 
towns paid wages that were at least 5 percent higher than the average 
wage in their area, and 16 percent paid wages that were at least 10 
percent higher than the area average. 

As a result, the Medicare labor cost adjustment for non-metropolitan 
areas may be based on average wages that are lower than wages paid by 
large town hospitals and based on average wages that are higher than 
wages paid by hospitals in small towns and rural areas. For example, 
the fiscal year 2001 labor cost adjustment for non-metropolitan 
Nebraska was based on an average hourly wage of $17.65. Yet, Nebraska 
hospitals in large towns had an average wage that year that was 11 
percent higher; small town Nebraska hospitals had an average wage that 
was 5 percent lower; and hospitals in rural areas of the state had an 
average wage that was 16 percent lower. 

Through Reclassification, Some Hospitals Receive a More Appropriate 
Labor Cost Adjustment: 

The administrative process for geographic reclassification allows 
hospitals meeting certain criteria to be paid for Medicare inpatient 
hospital services as if they were located in another geographic area 
with a higher labor cost adjustment.[Footnote 6] The first criterion 
concerns the hospital's proximity to the higher-wage "target" area. 
The proximity requirement is satisfied if the hospital is within a 
specified number of miles of the target area (15 miles for a 
metropolitan hospital and 35 miles for a non-metropolitan hospital) or 
if at least half of the hospital's employees reside in the target 
area. The second criterion pertains to the hospital's wages relative 
to the average wages in its assigned area and in the target area. This 
criterion is satisfied if the hospital's wages are a specified amount 
higher than the average in its assigned area and if its wages are 
comparable to the average wages in the target area.[Footnote 7] 

Rural referral centers (RRC) and sole community hospitals (SCH) can be 
reclassified by meeting less stringent criteria. These hospitals 
receive special treatment from Medicare because of their role in 
preserving access to care for beneficiaries in certain areas. RRCs are 
relatively large rural hospitals providing an array of services and 
treating patients from a wide geographic area. SCHs are small 
hospitals isolated from other hospitals by location, weather, or 
travel conditions.[Footnote 8] RRCs and SCHs do not have to meet the 
proximity requirement to reclassify. RRCs are also exempt from the 
requirement that their wages be higher than those of the average wages 
in their original market. 

Not All Higher-Wage Hospitals Can Be Reclassified: 

Of the 756 hospitals that paid wages high enough to qualify for 
reclassification, only 310, or 41 percent, were reclassified in fiscal 
year 2001. More than one-quarter of these higher-wage hospitals were 
in large towns, and 73 percent of them were reclassified. Higher-wage 
hospitals in large towns are likelier to be reclassified than other 
higher-wage hospitals because many are RRCs, which are exempt from the 
reclassification proximity criterion. 

In contrast to the nearly three-quarters of large town higher-wage 
hospitals that reclassified in fiscal year 2001, about half of higher-
wage hospitals in small towns and rural areas were reclassified. 
Almost 39 percent of the reclassified higher-wage small town and rural 
hospitals were exempt from the proximity criterion because they were 
RRCs or SCHs. Some non-reclassified, higher-wage small town or rural 
hospitals that were SCHs may have opted out of PPS to receive cost-
based payments from Medicare, making reclassification irrelevant. 

Moreover, even though metropolitan area higher-wage hospitals made up 
42 percent of the higher-wage hospitals, only 12 percent of them were 
reclassified in fiscal year 2001—a percentage far lower than that for 
higher-wage hospitals in other areas. Reclassified metropolitan 
hospitals paid wages that were about 10 percent above the average wage 
in their former area; those average wages are equal to the average 
wage in the new areas to which these hospitals were reclassified in 
fiscal year 2001. 

The likely reason that so few metropolitan higher-wage hospitals were 
reclassified is that few are close enough to a higher-wage MSA to meet 
the proximity criterion. More than two-thirds of the metropolitan 
hospital reclassifications in fiscal year 2001 were concentrated in 
two areas—California and a region that includes parts of New York, 
Connecticut, New Jersey and Pennsylvania—where metropolitan areas are 
close enough to each other that more higher-wage hospitals in these 
areas may be able to meet the reclassification proximity requirement. 

Certain Hospitals Can Be Reclassified Without Meeting Wage Criterion: 

While reclassification is designed to increase payments to hospitals 
paying wages significantly above the average for their area, certain 
provisions allow some hospitals that pay lower wages to reclassify. 
For example, an additional 116 hospitals were reclassified for a 
higher wage index in fiscal year 2001, even though they paid wages 
that were too low to meet the wage criterion. Prior to 
reclassification, these non-metropolitan hospitals had average wages 
that were close to the area average. With reclassification, these 
hospitals were assigned to areas with a labor cost adjustment based on 
wages that averaged 8 percent higher than their own. 

Of the 116 hospitals that reclassified for a higher wage index in 
fiscal year 2001, but failed to meet the wage criterion, 89 were RRCs 
(see table 1). About 42 percent of these had wage costs below their 
statewide non-metropolitan average. The other hospitals that 
reclassified, but did not pay wages that met the wage criterion, 
include those that were part of countywide reclassifications and those 
reclassified through legislation. 

Table 1: Reclassified Hospitals That Did Not Satisfy the Wage 
Criterion, by Reclassification Category, Fiscal Year 2001: 

Reclassification Category: RRCs; 
Hospitals with average wages too low to satisfy the wage criterion: 89;

Physician Fees Are Adjusted for Cost-of-Living, Practice Expense and 
Malpractice Premium Differences: 

Medicare's physician fee schedule, which specifies the amount that 
Medicare will pay for each physician service, includes an adjustment 
to help ensure that the fees paid in a geographic area appropriately 
reflect the cost of living in that area and the costs associated with 
the operation of a practice. This geographic adjustment is a critical 
component of the physician payment system. An adjustment that is too 
low can impair beneficiary access to physician services, while one 
that is too high adds unnecessary financial burdens to Medicare. 
Although much attention in recent months has focused on the method 
used to annually update the physician fee schedule, concerns have also 
been voiced about the appropriateness of the geographic adjustments. 
[Footnote 9] H.R. 4954, the Medicare Modernization and Prescription 
Drug Act of 2002, would require us to evaluate the methodology and 
data that Medicare uses to geographically adjust physician payments. 
[Footnote 10] We are beginning an analysis of the methodology and the 
available data to determine whether Medicare's geographic adjustment 
appropriately reflects underlying costs and whether beneficiary access 
to physician services has changed in certain areas. 

In adjusting 2002 fees for physician services, Medicare has delineated 
92 separate geographic areas. In some instances, these areas consist 
of an entire state. For example, physician fees are uniform across 
Connecticut. In other cases, a large city or group of cities within a 
state is classified into one geographic area and the rest of the state 
is classified into another. Maryland illustrates this case: Baltimore 
and surrounding counties are classified into one geographic area, and 
the rest of Maryland is classified as another. Finally, some large 
metropolitan areas, such as New York City and its suburban counties, 
are split into multiple geographic areas. 

Medicare's geographic adjustments for physician fees are based on 
indexes that are designed to reflect cost differences among the 92 
areas. There are three separate indexes, known as geographic practice 
cost indexes (GPCI), that correspond to the three components that 
comprise Medicare's payment for a specific service: (1) the work 
component, reflecting the amount of physician time, skill, and 
intensity; (2) the practice expense component, reflecting expenses, 
such as office rents and employee wages; and (3) the malpractice 
insurance component, reflecting the cost of personal liability 
insurance premiums. The overall geographic adjustment for each service 
is a weighted average of the three GPCIs where the weights represent 
the relative importance of the components for that service. Across all 
physician services in 1999, the average weights were approximately 55 
percent for the work component, 42 percent for the practice expense 
component, and 3 percent for the malpractice insurance component. 

The GPCIs are calculated from a variety of data sources. The work GPCI 
is based on a sample of median hourly earnings of workers in six 
professional categories. Physician earnings are not used because some 
physicians derive much of their income from Medicare payments, and an 
index based on physician earnings would be affected by Medicare's 
existing geographic adjustments. The work GPCI is a weighted average 
of the median earnings of these professions in the area and their 
median earnings nationwide.[Footnote 11] If the work GPCI was based 
solely on the median earnings in each area, physician payments would 
likely increase in large metropolitan areas and decrease in rural 
areas. The practice expense GPCI is based on wage data for various 
classes of workers, office rent estimates, and other information. The 
malpractice insurance GPCI is based on average premiums for personal 
liability insurance. 

Concerns have been raised that the current geographic adjustments for 
physician fees do not appropriately reflect the underlying geographic 
variation in physicians' costs and that, as a result, beneficiary 
access to services may be impaired in certain areas. Unfortunately, 
information on physicians' willingness to see Medicare patients is 
dated—although it does not indicate access problems. Data from the 
1990s show that virtually all physicians were treating Medicare 
beneficiaries and, if they were accepting new patients, accepted those 
covered by Medicare. A 1999 survey conducted by the Medicare Payment 
Advisory Commission (MedPAC) from that year found that 93 percent of 
physicians who had been accepting new patients were continuing to do 
so. It is unclear whether the situation has deteriorated since 1999. 
MedPAC is updating its survey, and the new results may shed light on 
this issue. However, MedPAC's survey results may not be able to 
identify access problems if they occur only in certain areas. As I 
said in my testimony before this Subcommittee in February, it is 
important to identify beneficiary access problems quickly and take 
appropriate action when warranted. As part of the work we are 
beginning on access to physician care, we will examine Medicare claims 
data to get the most up-to-date picture possible of access by area, by 
specialty, and for new versus established patients. 

Concluding Observations: 

Medicare's PPS for inpatient services provides incentives to hospitals 
to deliver care efficiently by allowing them to keep Medicare payment 
amounts that exceed their costs, while making hospitals responsible 
for costs that exceed their Medicare payments. To ensure that PPS 
rewards hospitals because they are efficient, rather than because they 
operate in favorable circumstances, payment adjustments are made to 
account for cost differences across hospitals that are beyond any 
individual hospital's control. If these payment adjustments do not 
adequately account for cost differences, hospitals are inappropriately 
rewarded or face undue fiscal pressure. The adjustment used to account 
for wage differences—the labor cost adjustment—does not do so 
adequately because many of the geographic areas that Medicare uses to 
define labor markets are too large. 

Geographic reclassification provides relief to some hospitals that pay 
wages that are higher than the average in their area. Yet, other 
hospitals paying higher wages cannot be reclassified. Still other 
hospitals get a higher labor cost adjustment than is warranted by the 
wages they pay, and many are in rural areas and may be facing 
financial problems. Their labor cost adjustment, however, is not 
necessarily the cause of these problems. Therefore, reclassification 
may not be the most effective mechanism to address the financial 
pressure faced by these rural hospitals. 

Madam Chairman, this concludes my prepared statement. I would be happy 
to answer any questions you or other Members of the Subcommittee may 
have.

from Medicare cost reports—which hospitals submit annually to Medicare. 

[2] For hospitals in Alaska and Hawaii, the non-labor portion of the 
payment is subject to a cost-of-living adjustment. 

[3] In addition to being affected by wage differences, the wage index 
is affected by differences in the occupational mix of hospital 
employees across geographic areas: The wage index can be higher in 
areas with a concentration of hospitals employing a more skilled (and 
more expensive) mix of staff, and lower in areas where hospitals 
employ a less skilled mix of staff. The Congress has required the 
Secretary of Health and Human Services to take into account the 
effects of occupational mix on the wage index beginning October 1, 
2004. 

[4] In general, MSAs are groups of counties containing a core 
population of at least 50,000, together with adjacent areas having a 
high degree of economic and social integration with that core. OMB 
defines the central county or counties of an MSA as those containing 
the largest city or urbanized area. An outlying county or counties 
qualify for inclusion in a metropolitan area based on commuting ties 
with the central counties and other specified measures of metropolitan 
character. The current geographic areas may change when OMB updates 
MSA boundaries in 2003 using population data from the most recent 
decennial census and revised OMB standards for including counties in 
an MSA. 

[5] In New England, the MSAs are defined in terms of cities and towns, 
rather than counties. 

[6] This discussion pertains only to the reclassification option to be 
paid based on a higher wage index. Other, less common reclassification 
options, such as county-wide reclassifications, are available. 

[7] A metropolitan hospital's average wage must be at least 8 percent 
higher than the average in its assigned area and at least 84 percent 
of its target area's average wage. A non-metropolitan hospital's 
average wage must be at least 6 percent higher than the average in its 
assigned area and at least 82 percent of its target area's average 
wage. 

[8] In general, SCHs may elect to be paid based on their own hospital-
specific costs or the applicable PPS payment amount. SCHs electing 
payments under PPS may qualify to be reclassified. Payments to SCHs

adjustment. See U.S. General Accounting Office, Medicare's Rural
