What 36223 covers

A physician selectively places a catheter in a common carotid artery or the innominate artery and images the ipsilateral intracranial carotid circulation. The service includes angiography of the extracranial carotid or cervical circulation when performed, along with the associated radiological supervision and interpretation. Interventional radiologists, neurointerventionalists, and other physicians performing diagnostic cervicocerebral angiography commonly report it in a hospital angiography suite or catheterization lab, such as during evaluation of carotid disease or a suspected intracranial vascular lesion.

Report the code for each unilateral service when the catheter position and imaged territory meet these criteria. The report should identify the catheterized vessel, side, angiographic territory, and physician interpretation. Catheter placement and the associated imaging supervision and interpretation are included. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
