Losing your Medicare Advantage plan keeps happening in the same states

Losing your Medicare Advantage plan keeps happening in the same states.

We mapped three years of it, state by state: the share of Medicare Advantage members whose plan was not offered in their county the next year, and who were not moved into another plan by their insurer. 2025 and 2026 are counted from CMS files. 2027 is our estimate from the 2027 Landscape file CMS released this week.

Nine states lost 10% or more of their members all three years: New York, Washington, Iowa, Maryland, Idaho, New Hampshire, South Dakota, North Dakota and Wyoming.

Some states get hit in waves. Idaho was 52% for 2026. Minnesota was 3% for 2025, then 31% for 2026, and our estimate for 2027 is 52%.

Nationally it was 2.0 million people for 2025 and 3.0 million for 2026, and the 2027 file points to about 3 million again. Before 2025, no year topped 1.1 million.

If you help people with Medicare in one of these states, a letter saying their plan is ending is now a normal part of the fall, not a rare event.

CMS confirms 2027 when it posts the crosswalk in October. The 2027 file is live in our MCP, so you can check any state or county yourself: vladahealth.com/data-access
