Can you tell me what code you would use for an extracranial angioplasty of internal carotid artery. No stent was placed and this is a Medicare patient. I didn't know if I should use 37799 and how do you feel about using GZ modifier since it is a non-covered procedure.

From a coding perspective, many experts advise that carotid angioplasty should reflect that it is angioplasty of a brachiocephalic branch (e.g., 35475, 75962-26). But this Dr. Z presentation for AAPC indicates CMS says 75962 is inappropriate because the carotid artery is not a peripheral artery. The advice given is to check with your payer and consider 37799-GY.
