Description

The Centers for Medicare and Medicaid Services (CMS) Virtual Research Data Center (VRDC) collection contains populated claim forms and administrative meta data describing individual providers, facilities, patients, care plans and transactions known to CMS. The data is sourced from Medicare, Medicaid, Child Health Insurance Program (CHIP) and Social Security Disability Insurance (SSDI) encounters among others. Third party data integration (National Death Index, Social Security Death Index) punctuates the product as well. Medicare includes Parts A, B, C and D. Medicaid includes both MAX(Y1999-Y2015) and TAF(Y2014-Ongoing) era claims. The VRDC provides ‘Research Identifiable Files’ (RIF) to authorized users. These RIF files contain complex clinical and financial information about individuals over time.
