The MedPAR file contains information about inpatient (IP) hospital and skilled nursing facility (SNF) stays that were covered by Medicare.  MedPAR records are created by rolling up information for a single stay from individual IP and SNF claims. The data on these claims was originally submitted on the CMS 1450 or UB04.

This file includes (variable highlights)

  • diagnosis (ICD diagnosis),
  • procedure (ICD procedure code)
  • admission, discharge dates or end date of covered benefits
  • charge amounts, total and assigned to specific departments
  • FFS reimbursement amount
  • hospital provider identification number 
  • some dummy records for Medicare managed care coverage of IP stays
