Ask Dr. Z

What is the code for this new procedure? "The patient had a severely calcified SFA and was going to be treated with lithotripsy at this intervention. Patient was given 10,000 units bolus of heparin, and then shockwave lithotripsy was performed with a 5mm balloon at the SFA. There were two tandem lesions separated by 6 mm. These were treated first with inflations of 4 atmospheres and then 6 atmospheres with shockwave therapy at each inflation. Then the balloon was carried more proximally and was treated in a similar fashion. There was a mildly resistant area in the SFA, which was treated with two more cycles. There was a nice angiographic result. I obtained a 5.5 shockwave balloon and treated the proximal SFA lesion and the common femoral artery. I treated the proximal lesion at 4 atmospheres, retrieving the balloon into the common femoral and inflating this to 6 and then 8 atmospheres, and treated with 2 more cycles. Follow-up angio revealed persistent disease, which was successfully treated once at 4 atmospheres." Would this new technology be reported with an unlisted code, or would I use current codes?
