The posted figure
Read with
- Counts individual-market Medicare Advantage plans; employer group plans are not included.
- CMS hides plan-county cells under 11 members, so counts are slight undercounts.
- Like-for-like compares filed benefits only; doctors, pharmacies and drug lists are not in the comparison.
- A plan's members are split evenly across its segments within a county; CMS does not publish enrollment by segment.
