CMS’s Virtual Research Data Center (VRDC)
Provided by the Center for Medicare and Medicaid Services (CMS), the VRDC now carries 17 years of Parts A and B claims data including diagnoses, procedures and medications dispensed in offices (mostly injectable), and vital status derived from Social Security death records. Since late 2006, it also contains Part D medication prescription claims (dispensed by community pharmacies). Very recently the cause of death (captured by CDC), has become available (1999-2016).
