The Centers for Medicare and Medicaid Services has appealed UnitedHealthcare’s win over its Medicare Advantage star ratings score.

CMS filed the appeal on Tuesday in federal court for the Eastern District of Texas. 

It is appealing the November 22, 2024 order mandating CMS recalculate the MA 2025 star ratings without consideration of a secret shopper call used to determine UnitedHealth’s score.

CMS gave no reason for the appeal in the court filing.
