CMS Releases 2027 Medicare Advantage Star Ratings

CMS released its 2027 Medicare Advantage star ratings on Oct. 8, according to Becker's Hospital Review, offering a clearer picture of plan quality than insurers' own marketing materials.

Each MA contract receives an annual rating from one to five stars. The scores help beneficiaries compare plans during enrollment, but they carry far bigger financial stakes for insurers. Ratings determine quality bonus payments, which plans use to fund extra benefits and stay competitive. Four stars is the critical threshold: contracts that hit it qualify for bonus dollars, while those that fall short lose a major revenue stream.

The release matters because star ratings sit at the center of MA economics. Strong ratings let plans offer richer benefits and attract more members, creating a reinforcing advantage. Weak ratings squeeze margins and limit what insurers can put in front of seniors. For an industry already navigating tighter reimbursement and rising medical costs, the 2027 scores will shape benefit designs, marketing, and bottom lines heading into next year's enrollment cycle.
