Quality ratings hit to key Medicare plan shakes Humana stock

Shares of Humana tumbled early Wednesday after the health insurer said a Medicare Advantage quality rating drop will hurt future bonus payments the company receives. The insurer said the number of customers currently enrolled in plans rated four stars or higher for 2025 is down 94% from this year. Humana said the rating on a large, national insurance plan that contains 45% of Humana’s enrollment fell a point to 3.5 points. Humana said it was talking to federal officials about the reduction. The company said it also is focused on improving its performance to regain its star rating.
