MedPAR consolidates Inpatient Hospital or Skilled Nursing Facility (SNF) claims data from the National Claims History (NCH) files into stay level records. The accumulation of claims submitted for the period commencing on a beneficiary's date of admission to an inpatient hospital or SNF and ending on the beneficiary’s date of discharge from that hospital or SNF represents one stay. In the case of a SNF stay where the beneficiary has not yet been discharged and remains a patient, the claims submitted between the admission date to the SNF through the time of the MedPAR file creation, represent one stay. A stay record may represent one or more final action claims.
NOTE: Any given MedPAR file represents a static snapshot of a specific stay at the time the data was sourced from NCH. As such, any given stay record on a specific update of MedPAR DOES NOT NECESSARILY represent the final coding and/or payment information for that stay because if subsequent adjustments to the claims that comprise the stay occur after MedPAR is run, they will not be reflected on the file.
This file is identical to the Expanded Modified MEDPAR - Skilled Nursing Facility (SNF)
This file is stripped of most data elements that will permit identification of beneficiaries. The SNF is identified by the six position Medicare billing number. The file contains records for 100% of Medicare beneficiaries who use SNF services. The file is available to persons qualifying under the terms of the Routine Use Act as outlined in the December 24, 1984, "Federal Register" and amended by the July 2, 1985, Notice.
The Final Rule is published in the "Federal Register" usually by the first week of September. This file is derived from the MEDPAR file with a cutoff of six months after the end of the fiscal year (March update file).
