Medicare Advantage Enrollment in Alaska

Alaska had 2,586 Medicare Advantage members in July 2026, by the CMS county file, which includes employer group plans. That is down 0.4% from Jul 2025. CMS's county file has no Alaska rows after July 2026, so the figures here are for July 2026. A missing row does not mean enrollment fell to zero. The contract file still lists Alaska with 2,273 members in September 2026.

Aetna/CVS leads with 47.7% of members who have a carrier label (contract file, September 2026).

Data as ofLast month in the county file

  • These totals include employer and union group plans.
    Why this matters

    The CMS contract and county files count group plans that retirees get through a former employer. They are not plans you can pick on your own. Counts here are larger than the individual-plan counts on county pages.

  • No Alaska rows in the county file after July 2026.
    Why this matters

    CMS's county file has no Alaska rows after July 2026, so the figures here are for July 2026. A missing row does not mean enrollment fell to zero. The contract file still lists Alaska with 2,273 members in September 2026.

  • Some months are missing from the source.
    Why this matters

    CMS did not publish every month. Lines break at a missing month instead of guessing a value. A dotted line, where shown, only joins the two sides.

Insurer not assigned in CMS data: 1.8% of all members in Sep 2026, 2.5% in Sep 2025. Shares leave these members out. Contract IDs are renumbered each January, so this page follows carriers, not contracts. A contract that serves several states carries one carrier label, so a carrier can appear in a state where it is not a local plan. See the carrier view for the whole nation.
