In this procedure, the provider performs imaging supervision and interpretation for angiography performed by inserting a catheter through a distal artery into the thoracic aorta and farther into the common carotid artery or cervicocerebral arch. He then injects contrast material to take the X–ray images of intracranial or extracranial arteries or of the cervicocerebral arch to detect any vascular disease. Report this code to represent only imaging supervision and interpretation for this procedure.
