Ask Dr. Z

For iliac artery stent procedures, we understand the coding is first based on pathology and then based on the type of endograft used to treat the pathology. For an iliac artery dissection (not stated for occlusive disease), should we use code 37236 or 34707 when a Cook Zilver 8 mm x 60 mm stent is used? Would this type of stent qualify for the ilio-iliac tube endograft code 34707, or would this be considered a “regular" stent code 37236? If the dissection was caused during a lower extremity revascularization procedure, is the iliac artery dissection stenting still codeable?
