Source and interpretation
CMS Medicare Monthly Enrollment, June 2026, published 2026-09-23. “MA & Other” retains the official combined CMS field label.
- 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.
