HCPCS Modifier Q3

Published 07/16/2020

Live kidney donor surgery and related services.

Guidelines and Instructions
Submit this modifier on services provided to a live kidney donor to indicate that the services are related to a kidney transplant.
  • All donor services must be submitted using the beneficiary's name (kidney recipient) and Medicare number 
  • It's very important to submit this modifier so recipient and kidney donor services can be distinguished from each other
  • For services rendered on/after October 1, 2015, we also suggest submitting ICD-10-CM code Z52.4 as a primary diagnosis
