Accessing CMS Data

HRS data are linked to detailed information about health care utilization from records maintained by the Centers for Medicare & Medicaid Services (CMS). Available data include:

CMS Research Files Documentation Available Years
Parts A and B Claims and Summary Files 1991-2015
Part D Drug Event Files Data Dictionary (.xlsx) 2006-2015
Minimum Data Set (MDS) Assessment and Summary Files Data Dictionary 1999-2015
Outcomes and Assessment Information Set (OASIS) Assessment and Summary Files 1999-2015
Medicaid Analytic Extracts (MAX) and Summary Files 1999-2012

Unlike other HRS restricted data, the HRS linked CMS data are created and supplied by others. The Medicare & Medicaid Resource Information Center (MedRIC) creates and supplies the linked data and the Research Data Assistance Center (ResDAC) provides authorization. So while HRS is your first step in applying for the HRS linked CMS data, you will have two more application processes to request and obtain the data through these organizations. HRS only provides cross-reference files that summarize the linkages to HRS data.

Read the MedRIC Documentation for HRS Data Requestors for descriptions of the summary and claims files.

View this graphic for an overview of the entire application process.

Step 4. Data Access

  • If you applied through the VDI, you will be contacted by HRS staff with the details you need to login to the enclave from your computer through the VDI.
  • If you applied through the Traditional License, you will receive data files from MedRIC, and cross-reference files from HRS.
