Source and scope

How this county directory is built

This page uses the CMS Contract Year 2027 PBP benefits, Landscape, and aligned MA service-area data. County identity comes from exact contract, plan, and segment geography; stable FIPS or SSA values are used only for source-backed identity and route disambiguation.

Contract-level geography and standalone Part D geography remain available through state, carrier, and contract directories rather than being presented as exact county plan cards. Medicare Plan Lookup is an independent quick-reference tool.
