The Centers for Medicare & Medicaid Services (CMS) finalized that Medicare Advantage (MA) organizations must submit to CMS, and update as needed, their provider directory data for publication on Medicare Plan Finder, the tool that beneficiaries use to compare and select Medicare Advantage plans. MA organizations must also attest at least annually that the directory information is correct. The intent is to provide Medicare beneficiaries with clear, up-to-date information about which doctors and facilities are in a plan’s network and what care options exist locally.
