Can imaging of the arch (36221) be reported with the codes for carotid or vertebral angiography?


No, the codes for carotid and vertebral angiography include imaging of the arch. 36221 should not also be reported. 36221 should only be reported for a true arch study (an examination of the carotid and vertebral arteries from a non-selective catheterization of the thoracic aorta) when this is the only procedure performed.
