The Medicare Physician Identification and Eligibility Records (MPIER) file contains one record for each practice setting for a physician. Thus, a physician will have multiple records in this file depending on the number of practice locations, specialties and affiliations (solo or group) they have. This file includes:

  • physician UPIN number,
  • name,
  • date of birth and death,
  • medical school and year of graduation,
  • state license number, 
  • primary and secondary specialties,
  • billing and business zipcodes,
  • affiliations (solo practitioner or member of a group practice)

This file was discontinued with the implementation of the National Provider Identifier (NPI).  The data is now found within the downloadable NPI database found from this website
