CPT® Code 36222

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

The CPT® Code 36222 refers to a specific medical procedure known as selective catheter placement in the common carotid or innominate artery. This procedure is performed unilaterally, meaning it is conducted on one side of the body, and can be approached through various methods, including percutaneous access via the femoral, axillary, brachial, or radial arteries. The primary goal of this procedure is to facilitate angiography of the ipsilateral extracranial carotid circulation, which involves imaging the blood vessels supplying the head and neck on the same side as the catheter placement. Additionally, this code encompasses all associated radiological supervision and interpretation necessary for the procedure, ensuring that the imaging is accurately conducted and analyzed. When performed, the procedure may also include angiography of the cervicocerebral arch, which is the area where the carotid arteries branch off to supply blood to the brain. This comprehensive approach allows for detailed visualization of the vascular structures, aiding in the diagnosis and management of various vascular conditions.
