Humana soars, Alignment plummets in 2027 Medicare Advantage star ratings
Humana's Medicare Advantage star ratings improved significantly in 2027, with 93% of its members in 4+ star plans, up from 41% in 2026. This could generate $3B+ in extra revenue in 2028, according to TD Cowen. Alignment Healthcare saw a major decline, with only 25% of members in 4+ star plans in 2027, down from 98%. The CMS methodology changes made it harder for insurers to achieve higher ratings, with the average star rating falling to 3.99.
