CMS’s October 8, 2026 fact sheet outlines the 2027 Star Ratings for Medicare Advantage and Part D plans, a key quality measure used by beneficiaries when comparing coverage options. The update is distinct from prior posts because it focuses on plan performance ratings rather than drug price negotiation, ACO participation, or payment models. For Medicare enrollees, the ratings can affect plan choice during enrollment and reflect how plans performed on quality and service measures.
