Checking for 2027
Medicare Annual Enrollment Period runs October 15 through December 7. Florida Marketplace open enrollment runs November 1 through January 15. What controls access is each plan’s 2027 provider directory, formulary, and pharmacy network for the exact plan ID—even if you plan to keep your current coverage, recheck doctors and prescriptions against those updated lists.
As of October 9, 2026: CMS’s Medicare Plan Finder updates describe replacing third-party sourced provider directory data in Plan Finder with 2027 data supplied by Medicare Advantage organizations and validated by CMS—each plan’s own directory for that transition, not one outside directory shared across all plans.
