MA Star Ratings Drama: Humana Gets Bad News, UnitedHealth Sues CMS

“Truly shocking” and “huge setback” were just two of a flood of analyst reactions to Humana Inc.’s Oct. 2 disclosure that its percentage of Medicare Advantage members in plans with 4 or more stars will plummet to 25% next year. That’s down from an estimated 94% for 2024 and is largely the result of a decline in Star Ratings for its largest contract, according to a new filing from Humana.

Although the full set of Star Ratings data won’t be released until next week, this development confirmed industry fears that rising cut points will diminish ratings — and related revenue. UnitedHealthcare, meanwhile, has already filed a complaint over CMS's scoring of one measure, which industry observers predict could be followed by similar challenges.
