What 36222 covers

An interventional radiologist, vascular surgeon, or neurointerventional specialist selectively places a catheter in one common carotid artery or the innominate artery and images the ipsilateral extracranial carotid circulation. The service is typically performed in an angiography suite to assess cervical carotid anatomy, such as suspected stenosis. Aortic arch imaging is included when performed; this code’s imaging territory is extracranial rather than intracranial.

Report one unit for the unilateral service and document the catheterized artery, side, clinical indication, and angiographic territory. The code includes the selective catheter placement and the associated angiography; do not separately report those same elements as though they were distinct services. It has a 0-day global period, so same-day preoperative and postoperative care is included. With other procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction. Modifier 50 identifies bilateral performance and CMS pays the bilateral procedure 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.
