The Medicare Claims Files contain information collected by Medicare to pay for health care services provided to a Medicare beneficiary. Data are available for each institutional and non-institutional claim type, which each record being a claim. Some of the information contained within these utilization files includes:
- procedure and diagnosis information
- dates of service
- revenue center detail
- payment and charge amounts
- beneficiary demographic information
- limited professional provider and facility data
Researchers working with the Research Identifiable (RIF) versions of the MedPAR or Inpatient and Skilled Nursing Facility (SNF) claims may find records that do not appear to correspond to the year of the file. These instances can usually be explained by how stays or claims are included in the files during file creation.
