Centene Maintains Leadership in Managed Medicaid Segment as Redetermination Metrics Settle


April 30, 2024



  • With pandemic protections ended and redeterminations returning to normal, Centene leads the Managed Medicaid market with over 13.1 million members in 4Q23, down by over 1.7 million, compared to 4Q22, or about 11.6%.
  • Elevance’s Medicaid membership shrunk by 12%, or about 1.1 million members, from 2022 to 2023.
  • UnitedHealth lost 700,000 (10.6%), with total 4Q23 Medicaid enrollment figures at 5.9 million, based on NAIC filings.
  • Molina’s 2023 year-end enrollment stood at 4.3 million, a decrease of 5.4% from 4Q22.
  • Independence Blue Cross (IBX) saw the smallest percentage drop of the top insurers, falling by 5%, or just over 131,000 members. IBX’s decline in Medicaid enrollment was counterbalanced by recent expansions in its state-specific AmeriHealth Caritas plans: 35,000 enrollees via expanded coverage in North Carolina and over 112,000 in new enrollees in Ohio.

About the Data

The data used in this brief was obtained from Mark Farrah Associates' Health Coverage Portal™ database, including information from the National Association of Insurance Commissioners (NAIC) and the California Department of Managed Health Care (CA DMHC).

Please note: There are differences in reported Medicaid membership between the NAIC and U.S. Securities and Exchange Commission (SEC) filings due to segment definitions, state laws, and other causes. This analysis is focused on the Managed Medicaid market as reported to the NAIC. In 2023 annual SEC 10K reports, Medicaid membership for Centene was 14.5 million, Elevance reported 10.5 million, UnitedHealth reported approximately 7.8 million, and Molina mentioned nearly 4.5 million. Independence Blue Cross does not file with the SEC.
