“Leaving” means present in the CY2026 landscape and absent in the CY2027 landscape for this geography. It is not an official termination: a plan can leave a county through a service-area reduction or be renumbered. Only a CMS crosswalk or non-renewal file says why.

Source & method

Geography: United States
Source: CMS Medicare Advantage and Part D Landscape files, CY2027 (CY2027_Landscape_202609.zip) and CY2026 (CY2026_Landscape_202609.zip); CY2027 data last updated by CMS September 22, 2026; ingested October 1, 2026
Plan: Contract ID + plan ID; segments count as one plan. Health plans are MA, MA-PD, SNP and 1876 cost plan rows; PDPs are counted by state and PDP region.
$0 premium: Monthly consolidated premium (Part C + D) of $0; for MA-only and cost plans without Part D, the Part C premium
Averages: Unweighted means across plan offerings. The landscape carries no enrollment, so they are not what members pay on average.
