Statement of Mark E. Miller, Ph.D., Executive Director, Medicare Payment Advisory Commission
U.S. House of Representatives
Subcommittee on Health, Committee on Energy and Commerce July 25, 2006 Medicare payment to physicians
Medicare expenditures for physician services are growing rapidly. In 2005 spending on physician services increased 8.5 percent, while the number of beneficiaries in FFS Medicare increased only 0.3 percent. To get good value for the Medicare program, the payment system should set the relative prices for services accurately. Providing incentives to control unnecessary growth in volume and intensity would be desirable, but it is much more difficult.
Measuring physician resource use
For Medicare beneficiaries living in regions of the country where physicians and hospitals deliver many more health care services there is no clear relationship with better quality of care or outcomes. Moreover, they do not report greater satisfaction with care than beneficiaries living in other regions. This finding, and others by researchers such as Wennberg and Fisher, are provocative. They suggest that the nation could spend less on health care, without sacrificing quality, if physicians whose practice styles are more resource intensive moderated the intensity of their practice.
MedPAC recommends that Medicare measure physicians’ resource use over time, and feed back the results to physicians. Physicians could then start to assess their practice styles, and evaluate whether they tend to use more resources than their peers. Moreover, when physicians are able to use this information with information on their quality of care, it will provide a foundation for them to improve the efficiency of the care they and others provide to beneficiaries. Once greater experience and confidence in this information is gained, Medicare might begin to use the results in payment, for example as a component of a pay-for-performance program.
Creating new incentives in the physician payment system
MedPAC has consistently raised concerns about the SGR as a volume control mechanism and recommended its elimination. We believe that the other changes discussed previously-pay for performance, encouraging use of IT, measuring resource use, setting quality standards for imaging services, and improving payment accuracy-can help Medicare beneficiaries receive high-quality, appropriate services and help improve the value of the program. Although the Commission’s preference is to directly target policy solutions to the source of inappropriate volume increases, we recognize that the Congress may wish to retain some budget mechanism linked to volume. An ideal volume control mechanism would overcome the incentive under fee-for-service to increase volume and instead create incentives for physicians to practice in ways that improve care coordination and quality while prudently husbanding Medicare resources. The Congress has tasked the Commission to evaluate several alternative volume control mechanisms including differing levels of application such as group practice, hospital medical staff, type of service, geographic areas, and outliers. We will report on these alternatives in March 2007.

By Don McCanne, MD
One of the most important features of a well-functioning national health insurance program is that it can use budgets to slow the growth in health care costs to a level closer to the growth in GDP. But what a nightmare that creates.
In a predominantly fee-for-service system, physicians respond to a slowing of rate increases by increasing the frequency and intensity of services provided (volume of services). To maintain a growth rate near that of the GDP, the rate per unit of service must be decreased to offset the increases in the number of units of services provided. This is the flaw in MedPAC’s SGR formula (sustainable growth rate). Medicare’s fee per unit of service must be reduced to slow the growth rate to a “sustainable” level.
What has been the source of the volume increase? Part of it has been that patients are brought back for return visits more frequently, and the levels of services have been increased from basic to moderate complexity. Another very important component has been the increased utilization of high-tech services, especially medical imaging. The explosion of spending in imaging has pulled a significant amount of funds away from physicians, especially family physicians and general internists just at a time that we are trying to reinforce the primary care infrastructure.
Virtually everyone agrees that the current rate of growth is not sustainable indefinitely. Costs will not be controlled without controlling volume. How do you do that? One possibility presented in this testimony is to identify the non-beneficial excesses and then educate physicians who, in response, would likely modify their practice patterns. This can be effective as has been demonstrated by the decline in the use of antibiotics in childhood viral respiratory infections once physicians were convinced that they were of no value. That approach will help, but it alone likely will not be sufficient. New innovations will continue to present new challenges.
MedPAC is currently evaluating several volume control mechanisms and will report their findings to Congress in March, 2007. Volume will be controlled, but how will they do that, and can we live with it? This is a process that requires intensive citizen oversight by the policy community. Heads up!
