Medicare Advantage
Humana leads Medicare Advantage in nine states, including Florida, Kentucky, Louisiana, North Carolina and Virginia, and is second in 12 more, according to the AMA’s 2024 data. It grew by 1.3 million members in 2026 as competitors cut plans.
Its star ratings rebounded sharply. For 2027, 95% of Humana’s Medicare Advantage members are in plans rated 4 stars or higher, up from about 20% for 2026, the company said (source). Higher ratings bring federal bonus payments, which Humana expects to lift results in 2028. It is still exiting plans covering about 600,000 members for 2027 (source).
Prior authorization is the trade-off to watch. A federal audit found Humana denied 72.3% of requests for long-term care hospital stays in June 2024; see our Prior Authorization Report Card and our Medigap vs Medicare Advantage guide.
Medicaid
Humana’s Medicaid business focuses on people eligible for both Medicare and Medicaid. Its 10-K lists Medicaid contracts in 10 states; the company counts 13 when newer contracts are included. It won a statewide HealthChoice Illinois contract that begins in January 2027 (source).
