Medicare Advantage and Part D plan exits threaten 2027 coverage stability

CMS-based reporting says 4.3 million beneficiaries will have MA or standalone Part D plans terminated at year-end: 3.1 million in MA-PD plans and 1.2 million in PDPs. A separate estimate says 7.8 million face broader plan disruptions; the measures are not equivalent. Beneficiaries should check exact plan, provider, and drug coverage and verify SEP and Medigap rights.
