Identifiable Data Files

Identifiable Data Files contain actual beneficiary-specific and physician-specific information. Identifiable Files require a formal request to be submitted to CMS for approval.

The Centers for Medicare & Medicaid Services (CMS) is responsible for administering the Medicare, Medicaid and State Children's Health Insurance Programs, as well as a number of health oversight programs. CMS gathers and formats data to support the agency's operations. Information about Medicare beneficiaries, Medicare claims, Medicare providers, clinical data, and Medicaid eligibility and claims is included. This data is made available to the public, subject to privacy release approvals and the availability of computing resources.

All requests for identifiable data must be developed and reviewed with the assistance of the Research Data Assistance Center (ResDAC), who may be contacted via web - or via email -

Once your data request has been reviewed by ResDAC, the final request can be sent to CMS as directed by ResDAC.

NOTE:  Please read the CMS Data Disclaimer - User Agreement - Privacy Protected Data (Downloads below) which contains important information regarding time frame for obtaining data.
