Interns and Residents Information System (IRIS) XML Format

Teaching providers: You must submit IRIS data for all interns and residents you claim on your cost reports. For cost reports with fiscal year beginning on or after:

  • October 1, 2021: Use the IRIS XML format to file your data.
  • October 1, 2022: Make sure the total graduate medical education and indirect medical education full time equivalents reported on the IRIS match the total reported on your as-filed cost report. Medicare Administrative Contractors (MACs) will reject the cost report if this information does not match.

See the instruction to your MAC (PDF), which includes a list of software vendors who submitted sample XML IRIS files that meet the new file format requirements. You are not required to use them.
