Why the plan count can change year to year
The number of Medicare Advantage plans available in a county isn't fixed — carriers enter and exit markets each year as Medicare's payment and Star-Ratings rules change. For 2026 the national Medicare Advantage plan count fell about 9%, and roughly 2.6 million members nationwide had their plan terminated and had to choose again (CMS, 2025). If your plan is non-renewed, you get a Special Enrollment Period — and your doctors and prescriptions may not carry over, so they're worth re-checking.
