VQI Medicare Matched Blinded Datasets

Change in Medicare-Match Process and Procedures – Please Note:

  • Timescales: access to Medicare-Match is provided in order of request and investigators should allow an additional 3-6 months after the National RAC approval
  • Use of the Medicare-matched data are governed by a Data Use Agreement (DUA) between Weill Cornell Medical College and the Center for Medicaid and Medicare Services (CMS). Data are kept on a secure server at Weill Cornell Medical College, Science and Infrastructure Center.
  • Requests for access to Medicare-Matched data will be reviewed and administered by the VISION team once a National RAC submission is approved. Detailed instructions will be provided to PIs after approval.
  • As the Medicare individual level data are subject to Data Use Agreements (DUAs) with the Centers for Medicare and Medicaid Services (CMS), no individual level data can be shared.

Please review the Vascular Implant Surveillance and Interventional Outcomes Network (VISION) policy that will govern access to these data going forward:
