CMS revised its Medicare Advantage star ratings methodology in a way that lifted ratings for large insurers, according to Modern Healthcare. The star system directly controls bonus payments — plans rated four stars or above receive significantly higher per-member payments from the federal government.
CMS's Star Ratings Overhaul Rescues the Biggest Medicare Advantage Insurers — For Now
A methodology reset lifts quality bonus payments for UnitedHealth, Humana, and CVS Health at a moment when all three badly needed the relief.

| UNH | UnitedHealth | +20.3% |
For Humana, a star ratings rescue from CMS isn't a tailwind — it's a lifeline. Bonus payments can swing billions in annual revenue.
Who cashes in: UnitedHealth Group UNH is the largest MA insurer by enrollment and the biggest dollar beneficiary of any ratings improvement. Humana HUM, which has been under severe earnings pressure from elevated medical costs, gets a lifeline — higher star ratings mean more bonus revenue to offset claims. CVS Health CVS, through its Aetna subsidiary, is the third major beneficiary. For Humana in particular, this is not a minor tailwind; the company has been warning investors about MA profitability for several quarters, and bonus payments can represent billions in annual revenue.
Who's exposed: Smaller regional MA plans that didn't benefit from the methodology change face a competitive disadvantage — the big three can price more aggressively with higher bonus revenue. Hospitals and health systems that negotiate rates with MA plans may find insurers using the bonus windfall to resist rate increases rather than passing it through.
What to watch next: Humana's next earnings call guidance update and whether management raises its MA margin outlook. If HUM lifts guidance citing star ratings improvement, the thesis is confirmed. Also watch for any legal challenges from plans that lost ratings under the new methodology.
