CMS data use is restricted to specific researchers to complete specific research projects only. ResDAC provides the required assistance in preparing documents for data requests, and CMS evaluates the requests. If CMS approves a data use request for medicare claims data, the approval is for a specific researcher to do a specific research project only. The CMS Medicare datasets below may be available for reuse by an NBER affiliate, or for NIA-sponsored projects by other researchers. Making an extract of CMS data takes time. CMS very rarely approves reuse of 100% files. Instead, they require researchers to select only the variables and cases necessary for the study.

Visit the ResDAC website for the latest instructions on how to make a reuse request, descriptions of datasets, and for assistance in preparing requests.

Please note that CMS constantly updates the requirements for making a request. All requests of any kind for CMS data must go through ResDAC to be considered by CMS. So please consult ResDAC for the correct information on how to reuse CMS data. Only ResDAC can provide current and correct advice.

One of the documents needed for a reuse request is a Letter of Support from the Original Requestor. The original requestor info and datasets are available below. Once this letter is fully and completely ready for David Wise's signature, please email an electronic copy plus the research protocol to Jean Roth. If eligible, she will provide information needed for a letter of support.

Datasets Available for Reuse

MCBS, NLTCS, and MPIER data at this time do not require extracts, so a non-NBER or NIA-supported researcher may request reuse of these files following ResDAC procedures.

E-mail Jean Roth with questions.
