Q & A with Dr. Z: Facility Coding for Coronary IVL (Shockwave)

by David Zielske, MD, CIRCC, COC, CCVTC, CCC, CCS, RCC

How would you recommend the facility coding for coronary intravascular lithotripsy (Shockwave) with a drug-eluting stent? We would bill C9600 for the stent, but how can we capture the intravascular lithotripsy (IL)? We are being told to add modifier 22 to C9600, but I thought this modifier was for professional use only.

There is no code for IVL in the coronary arteries at this time. The procedure was just FDA approved and, hopefully, they are working on new codes for us. We are not recommending any change in coding at this time.
