Reforming and Refining Medicare Payments
Absent reform, the Medicare program remains on a path that is fiscally unsustainable over the long term. This fiscal pressure heightens the need for the Centers for Medicare & Medicaid (CMS) to improve Medicare’s payment methods to achieve efficiency and savings.
- Since January 2009, CMS has implemented payment reforms for many parts of the program, such as Medicare Advantage, inpatient hospital, home health, and end-stage renal disease services. The agency has also begun to provide feedback to physicians on their resource use and is developing a value-based payment method for physician services that accounts for the quality and cost of care. Efforts to provide feedback and encourage efficiency are crucial because physician influence on the use of other services is estimated to account for up to 90 percent of health care spending.

- In addition, CMS has taken steps to ensure that some physician fees recognize efficiencies when certain services are furnished together, but the agency has not targeted the services with the greatest potential for savings. Under the budget neutrality requirement, the savings that have been generated have been redistributed to increase physician fees for other services. Therefore, GAO recommended in 2009 that Congress consider exempting savings from adjusting physician fees to recognize efficiencies from budget neutrality to ensure that Medicare realizes these savings.

- GAO’s work has also shown that payment for imaging services may benefit from refinements. Specifically, CMS could add more front-end approaches to better ensure appropriate payments, such as requiring physicians to obtain prior authorization from Medicare before ordering an imaging service.
Highlights of GAO-08-402 (PDF)
- CMS also has opportunities to improve the way it adjusts physician payments to account for geographical differences in the costs of providing care in different localities. GAO has recommended that the agency examine and revise the physician payment localities it uses for this purpose by using an approach that is uniformly applied to all states and based on the most current data. CMS agreed to consider the recommendation, but was concerned about its redistributive effects. The agency subsequently initiated a study of physician payment locality adjustments. The study is ongoing and CMS has not implemented any change.

Another major Medicare payment challenge involves the Medicare Advantage program (MA—or Medicare Part C), in which private health plans provide health care coverage to Medicare beneficiaries. Private health plans were originally introduced into Medicare as a potential cost-saving measure, but the Medicare Payment Advisory Commission estimates that in 2009, Medicare payments to MA organizations will amount to $12 billion more than would have paid if these beneficiaries were served in Medicare's traditional fee-for-service program. GAO's work has shown that MA plans have spent less of their total revenue on providing care than originally projected and that some beneficiaries can have higher out-of-pocket costs in MA plans than in the traditional Medicare program

Our examination of payment rates for home oxygen found that although these rates have been reduced or limited several times, further savings are possible. As we reported in January 2011, if Medicare used the methodologies and payment rates of the lowest-paying private insurer of eight private insurers studied, it could have saved about $670 million of the estimated $2.15 billion it spent on home oxygen in 2009. Additionally, we found that Medicare bundles its stationary equipment rate payment for oxygen refills, but refills are required only for certain types of equipment, so a supplier may still receive payment for refills even if the equipment does not require them.

Beginning in 2011, CMS is required to use a single payment to pay for end-stage renal disease (ESRD) dialysis and related services, which include injectable ESRD drugs. Questions have been raised about this new payment system's effects on the access to and quality of dialysis care for certain groups. As required by law, CMS's proposed design for the new payment system includes two payment mechanisms to address differences across beneficiaries in their expected cost of dialysis care. The agency's preliminary plans for monitoring the effects of the new payment system build on existing initiatives, but it is unclear whether CMS will monitor the effects on the quality of and access to services for various groups of beneficiaries.

CMS should take further actions to refine Medicare's payment methods and the collection of data used as a basis for setting payment rates and assessing their effects, such as
- reducing home oxygen payment rates and removing payment for portable oxygen refills from the payment for stationary equipment.
Highlights of GAO-11-56 (PDF)
- establishing and implementing a formal plan to monitor the expanded home dialysis bundled payment system to determine whether home dialysis utilization rates increase as CMS expects and begin monitoring access to and quality of dialysis care for certain beneficiary groups as soon as possible after implementation of new payment system,

- enhancing its new profiling system that identifies individual physicians with inefficient practice patterns by including in its system empirically-based standards that set the parameters of efficiency and financial or other incentives for individual physicians to improve the efficiency of the care they provide, and by developing methods for measuring the impact of physician profiling on Medicare spending, and use the results to improve the efficiency of care financed by Medicare, seeking legislation as necessary

- improving management of approval of payment for imaging services; and

- systematically reviewing services commonly furnished together and capturing those efficiencies in payments, focusing on those service pairs that have the greatest impact on Medicare spending.
In addition, Congress should consider exempting savings realized from payment changes for services commonly furnished together from budget neutrality, so that savings accrue to Medicare.
