The Medicare Advantage program gives commercial health insurers and managed care companies a chance to provide the an alternative to what CMS calls “Original Medicare” coverage.
Some Medicare enrollees use Medicare supplement insurance to fill in the gaps in Original Medicare programs. Other people use Medicaid; sign up for new or experimental programs, such as PACE plans; or have no protect against health care costs other than Original Medicare itself.
We compared the latest data with the year-earlier data and created a map showing where the Medicare Advantage program’s share of all Medicare-eligible people grew, shrank or held steady in the 50 states. You can see the map above. In states with big, bright green dots, Medicare Advantage plans increased their share of those state’s Medicare-eligible residents more than about 2%.
In states with bigger, darker red dots, Medicare Advantage plan issuers reported weak enrollee share growth, or a small drop in enrollee share.
For data on all 50 states, see the table below.
