Ask Dr. Z

What catheter and imaging codes would you use for the following? Code 36226 doesn't seem appropriate since the catheter wasn't in the vertebral artery, and code 75710 doesn't apply since there are no findings for the subclavian.

"Through the sheath, a 4 French catheter was navigated over a guidewire into the following vessels: right common carotid artery, right internal carotid artery, right subclavian artery (adjacent to the right vertebral artery origin), and left common carotid artery.

Right subclavian artery: There is a stent seen in the right vertebral artery origin with no evidence of residual or recurrent stenosis within the stent or narrowing within the remainder of the right vertebral artery. The basilar artery and its branches are well visualized and normal in appearance. There is no posterior circulation, vascular anomaly, or stenosis."
