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.

Where HCSC/BCBS has members

States where HCSC/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.

Holds 20% or more: Vermont.
