About contract pages

Why plans are grouped by contract

Medicare plan codes begin with a five-character CMS contract ID such as S3521. A contract can contain multiple plan IDs and service-area segments, so related codes can share the same contract while having different benefits or availability.

The records on this page come from the same official CMS 2026 sources used by Medicare Plan Lookup. Open the individual plan page and confirm final details in current official plan documents before relying on a benefit or cost-sharing amount.
