## Highlights

Medicare Advantage (MA) plans are an alternative to the original Medicare fee-for-service (FFS) program. Private fee-for-service (PFFS) plans--one type of MA plan--give beneficiaries an option that is more like Medicare FFS than other MA plans, with a wider choice of providers and less plan management of services and providers. PFFS enrollment increased from about 35,000 beneficiaries in June 2004 to about 2.3 million in June 2008. This report compares PFFS plans to other MA plans and Medicare FFS in three areas: (1) characteristics of beneficiaries, (2) financial risks for beneficiaries who do not contact their plans before receiving services, and (3) disenrollment rates. To do this work, GAO reviewed materials from a selected sample of nine PFFS plan sponsors, analyzed Medicare data, and interviewed officials from CMS, which administers the Medicare program, and other organizations.
