Data File Exchanges

CMS provides state Medicaid agencies with multiple data exchanges to support coordination and program operations for people who are dually eligible for Medicare and Medicaid.

These data exchanges include:

  • Enrollment Database (EDB) File

  • Medicare Prescription Drug, Improvement, and Modernization Act (MMA) File

  • Territory Beneficiary Query (TBQ) File

  • Buy-In File Exchange

These data exchanges are covered by an Information Exchange Agreement (IEA) and accompanying Data Request and Attestation (DRA) form. For more information on these agreements, please visit the Data Agreement Page.

CMS is modernizing Medicare Enrollment & Premium Payment Systems legacy applications to a modern, cloud-based architecture. These changes will improve the quality of services to Medicare beneficiaries, improve information security, reduce costs, and improve operational efficiencies. Part of this effort includes a shift from the Enrollment Database (EDB) State File Exchange to the Territory & State Beneficiary Query File (TBQ) by June of 2022. To aid in this transition, CMS hosted  a webinar to discuss the retirement and transition process and next steps.
