How these numbers are made
- Members are visible members: CMS suppresses any plan-county cell of ten or fewer, so small counties undercount. Market share excludes employer group plans.
- Enrollment is Oct 2026; the twelve months run Nov 2025 to Oct 2026; the election step compares December 2025 with January 2026.
- Plan fates are the ones assigned for contract year 2027; benefit design is the 2027 filing; the rating is the 2027 overall Star Rating of each carrier's contracts, weighted by members in Alabama.
- A carrier is a parent organization; its brands in Alabama may carry other names. The rank 1st to 8th counts every parent with visible members in 2026.
- Every figure comes from public CMS data as Livmor reads it, and the page is rebuilt when a new month posts. Livmor Carrier Command, public CMS data.
