Ask Dr. Z

I think I have read all of the Q&A's regarding coding catheterization with the lower extremity revascularization codes and haven't seen this one. Pt has catheter access into left common femoral artery with advancement to the abdominal aorta for lower extremity run-off = 75716 (abd angio was not done). Catheter is advanced into the aortic arch for arch angiogram = 75650 then pulled down into the left common iliac for insertion of stent = 37221. My question, can 36200 be billed since the catheter was inserted into the aortic arch from the same access site? I know that if the catheter is inserted into the carotid, renals etc I would be able to bill for the selective cath and if the catheter were only advanced into the abdominal aorta then I wouldn't bill for it. I'm just not sure about the non-selective cath into the aortic arch since the angiogram is of the carotids and subclavians. Thanks for your help.
