Enrollment by state and territory
Select a geography for its county table. Percentages use total Medicare beneficiaries in the same CMS row as the denominator. The national CMS row is 569,113 beneficiaries higher than the sum of the listed geographies because CMS also includes Foreign and Other Outlying Areas plus a suppressed Unknown row in the national total.

Source and caveats
Source: CMS Medicare Monthly Enrollment, published 2026-09-23. The collector discovers the latest API distribution from the CMS public data catalog before requesting the reporting month.
- CMS suppresses some small counts with an asterisk; suppressed values remain null in this snapshot.
- Medicare Advantage and Other Health Plans is the CMS-published combined measure and is not limited to Medicare Advantage alone.
- Enrollment counts describe a reporting month and do not compare plan benefits, provider networks, quality, or personal costs.
This page reports enrollment, not plan price, quality, benefits, provider access, or personal eligibility. CMS landscape cost files remain a separate next-phase join.
