Change in Medicare-Match Process and Procedures – Please Note:
Medicare-Match data are only available for EVAR, OAAA, PVI, TEVAR, CAS, INFRA and SUPRA datasets. Please see the new process here.
- Timescales: access to Medicare-Match is provided in order of request and investigators should allow at least 3-6 months after the National Arterial 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.
- 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.
- Requests for analyses of 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 volume of requests for VQI-Medicare analyses is substantial and some projects requesting Medicare-match are not possible due to limitations in the Medicare-match datasets, or may not benefit from Medicare-match data, the VISION Data Core will review projects and assign priority based on the following additional criteria:
- Clear need for Medicare-derived outcomes in order to meet project goals.
- Feasibility and clarity of analytic plan
- Late Outcomes Descriptive Memo
- Survival Reintervention and Surveillance (SRS) Report FAQs
- Process for Requesting Analyses
