CPT® Code 36223

Selective catheter placement, common carotid or innominate artery, unilateral, any approach, with angiography of the ipsilateral intracranial carotid circulation and all associated radiological supervision and interpretation, includes angiography of the extracranial carotid and cervicocerebral arch, when performed

The CPT® Code 36223 refers to a specific medical procedure known as selective catheter placement in the common carotid or innominate artery, performed unilaterally through any approach. This procedure is accompanied by angiography of the ipsilateral intracranial carotid circulation, as well as all associated radiological supervision and interpretation. Additionally, it includes angiography of the extracranial carotid and cervicocerebral arch when these are performed. The common carotid artery is a major blood vessel that supplies blood to the head and neck, and the innominate artery (also known as the brachiocephalic artery) branches off to supply the right arm and head. The selective catheter placement allows for targeted access to these arteries, facilitating diagnostic imaging and potential therapeutic interventions. The procedure typically involves the use of fluoroscopic guidance to ensure accurate placement of the catheter, which is essential for obtaining high-quality angiographic images that can assist in diagnosing various vascular conditions. The use of radiopaque contrast media during the angiography enhances the visibility of the blood vessels, allowing for detailed assessment of the arterial structures and blood flow.
