Medicare Advantage · Plan year 2027 · CMS data
3.15M people must pick a new Medicare Advantage plan for 2027. Here is where they live.
CMS released the 2027 plan landscape on September 28 and the plan crosswalk on October 1. This page turns both into one map: which plans were pulled, where premiums moved, what drug plans cost, and how many members in each state and county have a plan that ends on January 1.
Members who must pick a new plan
Medicare Advantage members whose 2026 plan is ending, or is leaving their county, on January 1, 2027. They are not moved to another plan automatically.
Source: CMS CY2027 Plan Crosswalk (October 1, 2026) matched to CMS September 2026 enrollment by plan and county. Individual MA plans only.
Who has to pick a new plan
The crosswalk says what happens to every 2026 plan. Members of a terminated plan, or of a plan that continues but drops their county, get a non-renewal letter by October 2 and are not enrolled anywhere automatically. They have until December 7 to choose, with a special enrollment period running through February 28, 2027.
By what happened to the plan
90% of affected members are in regular, non-SNP plans. 8% are in D-SNPs.

Which carriers are sending members shopping
Members in a terminated plan or a dropped county, by parent company. The five largest account for 58% of the total.

How these numbers were built
Plan counts, premiums, access and drug plan figures come from the CMS 2027 Medicare Advantage and Part D Landscape state-by-state fact sheets published September 28, 2026. Plan counts are statewide totals; a plan sold in more than one state is counted once per state, and any single county sees far fewer plans. Premium averages are CMS’s simple average across all plans offered in the state, not weighted by enrollment.
Members who must pick a new plan come from the CMS CY2027 Part C and D Plan Crosswalk (October 1, 2026) matched to CMS Monthly Enrollment by Contract, Plan, State and County for September 2026. Individual plans only (Local and Regional CCP, PFFS, MSA); employer group, Cost and PACE plans are excluded. A member is counted when the crosswalk shows no successor plan (terminated), or when the successor plan’s 2027 service area in the CY2027 landscape file does not include the member’s county (dropped county). A plan listed as both terminated and consolidated is treated as consolidated, and its members are counted only if their county is dropped. CMS suppresses county cells with 10 or fewer members, so true totals run slightly higher.
Most expensive drug plan was pulled from Medicare.gov Plan Finder on October 1, 2026, using one ZIP code in each state’s largest metro. Stand-alone drug plan regions are statewide, so the result holds for the whole state.
