HCPCS 36222

Selective catheter placement, common carotid or cervical vertebral artery, unilateral, any approach, with angiography of the ipsilateral head and neck carotid circulation, including all selective arch arteriography and neck angiography; with angiography of extracranial carotid system

AI EXPLANATION: A carotid angiogram is an imaging procedure that examines the blood vessels in the neck leading to the brain. A doctor inserts a thin, flexible tube called a catheter into an artery, guides it toward the neck, and releases a special dye. X-ray images are then taken to show blood flow and check for narrowing, blockages, or abnormalities in the carotid arteries.
