Ask Dr. Z

I am reading in your example #2 under the AV shunt interventions chapter. It reads "2) Patient with clotted left leg dialysis graft undergoes cross catheter technique (36147, 36148) with shuntogram (included) and declot utilizing a thrombectomy catheter (36870). An arterial inflow stenosis in the native iliac artery 8 cm proximal to the arterial anastomosis is ballooned (36245, 37220) as is a common iliac vein stenosis (35476, 75978)." my question is concerning the 36245 coded with 37220. Wouldn't 36245 bundled with 37220? I would think that you would only be able to capture 37220 and not the cath placement code. What is your reasoning for add both 36245 and 37220? I have a similar situation AV shunt in lower leg venous outflow stenoses treated with stent deployment. I thought I should code with 36147, 37221.
