Medicare Enrollment by Age Group and FFS Status, 2005 - 2014

Description: The majority of Medicare beneficiaries are enrolled in fee-for-service (FFS) rather than managed care (i.e., Medicare Advantage [MA]plans). Beginning in 2005, there is a shift toward managed care enrollment, which is more pronounced each year. This is likely due to the implementation of the Medicare Part D prescription drug benefit. Medicare enrollees who were 65-74 years of age were the most likely group to select MA over FFS Medicare, although the majority of beneficiaries were still FFS by 2014.

Technical Notes: Full or nearly full fee-for-service (FFS) coverage = 11 or 12 months during the year with Medicare A or B coverage, but without HMO (i.e., Medicare Advantage) any of the months.

Technical Notes: Full or nearly full fee-for-service (FFS) coverage = 11 or 12 months during the year with Medicare Part A or B coverage, but without HMO any of the months. American Indian, Native American, Other, and Unknown races are grouped together due to small cell sizes. An additional Race classification variable is available from 2006 forward, called RTI Race – which more accurately captures the proportion of Hispanics.
