Questions
What counts as a plan exit?
A prior-year Medicare Advantage plan no longer offered in a county on January 1: terminated or non-renewed in the CMS crosswalk, or a service area reduction.
Why are some member counts zero?
CMS suppresses enrollment counts of 10 or fewer, so totals are a floor.
Where are the preliminary 2027 changes?
See the 2027 Medicare Advantage plan changes by county page.
