Data as ofCMS contract file
- These totals include employer and union group plans.
Why this matters
Carrier shares: all Medicare Advantage contracts, including employer group, from the CMS contract file. Share is of members with a carrier label. This file and the state file give different totals, so these shares do not apply to state or county member counts.
- Some months are missing from the source.
Why this matters
Missing months: July 2023 and December 2023 are absent from the state and county file; July 2023 is absent from the contract file. Lines break at a gap. Nothing is filled or averaged across it. Year-over-year changes compare the same calendar month, so July 2023 and December 2023 cannot be compared.
- Some contracts have no carrier name.
Why this matters
Insurer not assigned in CMS data: 0.6% of members in September 2026 (225,918), against 10.7% in January 2023. These are mostly retired contracts with no carrier label. Shares divide by members with a label so old and new months compare. When the unassigned bucket is above 3% in either month, treat share changes as rough.
- Shares jump each January. Compare same months.
Why this matters
Counts and shares step at each January, when plan-year contracts and annual elections take effect. A 12-month change is mostly one January step plus drift. CMS posts January counts late, so compare November with February or March, not January alone.

Most of the drop came in one month, January 2026 (−0.87 points). Contract numbers and plan years reset each January, so a carrier's share can jump in that month. Compare same months, or November with February or March, and not January alone.

Areas where Elevance/Anthem/BCBS had the most labelled members, September 2026
Where Elevance/Anthem/BCBS has members
States where Elevance/Anthem/BCBS has 1,000 or more members, largest first. Share is of that state's labelled members in September 2026. Change is in percentage points since September 2025. States where a carrier is small may be missing: the data keeps each state's ten largest carriers and any carrier above 1%. A contract that serves several states carries one carrier label, so a carrier can show members in a state where it is not a local plan.
