Interns and Residents Information System XML Format: Updated Vendor List

Teaching providers: You must submit Interns and Residents Information System (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 doesn’t match.

We updated the instruction to your MAC (PDF) to correct the name of a software vendor.
