Medicare and Medicaid Patient Data are available in the National COVID Cohort Collaborative (N3C) Enclave!
Centers for Medicare and Medicaid Services (CMS) Medicare data in its original Claims format (i.e. not converted to OMOP (Observational Medical Outcomes Partnership)) linked to N3C Electronic Health Record (EHR) data via privacy preserving record linkage (PPRL) are now available in the Data Catalog. N3C is making these data available in their original vendor-derived claims format for those with experience in claims data analysis, and to increase collaboration between researchers familiar with claims and EHR-sourced data.
CMS Medicaid data in OMOP format are now available in the Data Enclave. These data, along with the Medicare OMOP data added last fall, provide researchers a more complete picture of patients’ medical histories. With 16 data partners currently linking to CMS data, these resources provide additional information on 173k Medicare patients and 38k Medicaid patients, including visits, procedures, diagnoses, drugs, and other information.
Researchers may access CMS data by filing a Data Use Request with the ‘CMS’ PPRL External Dataset option. For documentation, webinars, and guidance about these data, see the PPRL Module in the N3C Training Portal.
