Tracking Medicare Health and Prescription Drug Plans Monthly Reports
These briefs present monthly data on Medicare Advantage participation, enrollment, and penetration. They also summarize activities by the Centers for Medicare and Medicaid Services (CMS), participating health plans, and the research community pertaining to the Medicare Advantage program and prescription drug plans that began serving the Medicare population in January 2006. Because of funding constraints, as of June 2010 only the monthly summary enrollment table will be circulated.

Please note that these are January 2011 data, which often provide a very incomplete and often misleading profile of changes that occurred in the open enrollment season. We expect enrollment figures for February and March to provide a more complete picture of how 2011 enrollment was affected by changes in MA offerings resulting from MIPPA and other annual changes.
