How should the use of DFR be coded in the facility setting?
DFR, or diastolic flow reserve, is a method of coronary flow reserve measurement that does not utilize the administration of a hyperaemic agent in order to measure the functional severity of coronary lesion. At this time in Q2 of 2023, for facility coding, per AHA coding clinic for HCPCS Third Quarter 2022 page 11, non-hyperemic pressure measurement (iFR, DFR, RFR) should be coded with unlisted procedure code 93799. Professional fee coding of DFR and other non-hyperemic flow reserve measurements may continue to be reported with 93571 and/or 93572 with modifier -52 applied per CPT® Assistant May 2015 Vol 25 Issue 5 page 10 instruction.
