DUA Extension and Closure Policy

All DUAs, regardless of how the data is accessed, must be extended annually or closed if you are no longer using the data. DUAs that are not closed or extended within 30 days after the expiration date are in violation of the terms of the DUA and will be forced to close and the data destroyed. An expired DUA is a violation of the agreement and prevents any action on all DUAs for your organization.

Important Research Data Request & Access Policy Changes

(Updated 09/20/24): In February 2024, CMS announced planned changes to our research data access policy to help protect sensitive beneficiary information from increasing security risks. These changes included transitioning most research studies to the Chronic Conditions Warehouse Virtual Research Data Center (CCW VRDC) and increasing physical data fees to cover growing costs associated with physical data provisioning. CMS released a Request for Information (RFI) to gather feedback from researchers on these changes. 

New Enrollee-level EDGE Data Now Available for Research

DUA Extension and VRDC Access Renewal Reminder

Reminder: Data Use Agreements (DUAs) and Virtual Research Data Center (VRDC) access needs to be extended or renewed annually. These are two separate actions with separate expiration dates. ResDAC recommends creating a calendar reminder 60 days before the expiration to begin the process of extending the DUA or VRDC access. Missing an email reminder is not an acceptable explanation for missing a renewal deadline.
