Indirect Medical Education (IME) Adjustment

What it means

This code isn't a denial — it indicates that the payment amount was adjusted because the billed amount included an Indirect Medical Education adjustment, which is a Medicare add-on payment for teaching hospitals that train medical residents. The adjustment reflects additional costs these hospitals incur due to their teaching mission and typically appears on institutional claims from Medicare-certified teaching facilities.

Common causes

Claim submitted by a teaching hospital with an approved IME adjustment factor on file with CMS
Inpatient hospital claim where Medicare applies DRG-based payment plus the IME add-on
Facility's IME adjustment factor changed due to updated resident-to-bed ratios
Claim processed under a Medicare Advantage plan that mirrors traditional Medicare's IME methodology

How to fix it

Confirm the facility is a recognized teaching hospital with a valid IME adjustment percentage on file
Review the remittance advice to verify the IME adjustment amount aligns with the facility's current CMS-approved factor
Check that the claim was coded with the correct DRG, since IME is calculated as a percentage add-on to the DRG base payment
If the adjustment seems incorrect or missing, contact your Medicare Administrative Contractor (MAC) to verify the facility's IME status and calculation
Cross-check your cost report data and resident counts if the adjustment amount seems inconsistent with prior periods

Appeal / resubmit

Since CARC 74 reflects an informational payment adjustment rather than a denial, there is typically nothing to appeal unless the adjustment amount appears to be calculated incorrectly. If you believe the IME percentage or payment amount is wrong, contact your MAC with your hospital's current CMS Medicare cost report and IME adjustment factor documentation to request a recalculation.

Primarily teaching hospitals with CMS-approved Indirect Medical Education adjustment factors, since this payment is designed to offset the higher costs of training medical residents.
