The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) made many changes to the Medicare program, including changes that increased the incentives for preferred provider organizations (PPOs) to serve broad regions of the country. About 13 percent of Medicare's 42 million beneficiaries currently are enrolled in private health plans; nearly all of those beneficiaries are in health maintenance organizations that primarily serve metropolitan areas. The service areas of regional PPOs generally would be larger than those of private plans that currently participate in Medicare and would include many areas that are not served by those plans.
This paper describes how the Congressional Budget Office (CBO) analyzed the likely effects of the MMA's provisions for regional PPOs. In accordance with CBO's mandate to provide objective, impartial analysis, this paper makes no recommendations.
Lyle Nelson of CBO's Health and Human Resources Division prepared the paper, with contributions from Shawn Bishop, under the general supervision of Steve Lieberman (formerly of CBO). Todd Anderson provided assistance with data and tabulations, and Meenakshi Fernandes fact-checked the paper. James Baumgardner, Tom Bradley, Philip Ellis, Arlene Holen, David Moore, Sven Sinclair, and Bruce Vavrichek, all of CBO, provided thoughtful comments on drafts, as did Joseph Antos of the American Enterprise Institute and William Scanlon, an independent consultant. (The assistance of external reviewers implies no responsibility for the final product, which rests solely with CBO.)
Christine Bogusz edited the paper, and John Skeen and Loretta Lettner proofread it. Maureen Costantino prepared the paper for publication and designed the cover. Lenny Skutnik produced the printed copies of the report, and Annette Kalicki produced the electronic versions for CBO's Web site.
