Data Available to CMS Contractors

CMS Contractors may require access to CMS data to conduct their contracted work. Access to data containing controlled unclassified information by CMS Contractors requires a data use agreement (DUA) with CMS. The DUA ensures contractor compliance with various laws, regulations, and CMS policies. It also creates a traceable record of the data files being accessed by each CMS Contractor. 

 

Contractor DUA requests are submitted via CMS’ data disclosure tracking system, EPPE. CMS Contractors must adhere to all policies in the Contractor DUA Terms and Conditions (PDF) at all times. 

 

CMS CORs and contractors may submit questions about Contractor DUAs or the process for requesting files to datauseagreement@cms.hhs.gov. 

How to get started submitting a Contractor DUA: 

  1. CMS COR registers for the CMS Contact (COR) role in the EPPE system. See more information in the “Register for EPPE” section below. 

  2. CMS Contractor registers for the “DUA Requester” role in the EPPE system. See more information in the “Register for EPPE” section below. 

  3. CMS Contractor completes the required forms. See more information in the “Forms” section below.  

  4. CMS Contractor (DUA Requester) creates and submits the DUA Request in EPPE. Use the training modules below for assistance with this step.  

  5. CMS COR reviews and approves the DUA Request. Use the training modules below for assistance with this step.  

  6. CMS DUA Management Team reviews the DUA Request and provides a response within 3 business days.
