Claims contain Information on patient demographic characteristics, diagnoses, procedures, and cost for each use of health service. Part D drug data are also available since 2007 and can be linked to the claims data. Researchers can use these data to conduct studies on health outcomes, health care access, and health disparities. The Research Data Assistance Center (ResDAC) ( provides free technical support on how to use these data. Information on other related datasets and workshop schedule is also available on the ResDAC website. Under the contract with CMS, ResDAC handles all the requests for using these data.
