Find, Request and Use CMS Data

CMS appreciates the feedback researchers provided over the past 18 months in response to CMS’ Request for Information and feedback opportunity. Based on this feedback, CMS has decided to delay the requirement to transition all research studies into the CCW VRDC indefinitely. Instead, CMS is implementing updated security requirements to better protect patient information while still meeting researchers’ needs.
