CPT® Code 37215

Transcatheter placement of intravascular stent(s), cervical carotid artery, open or percutaneous, including angioplasty, when performed, and radiological supervision and interpretation; with distal embolic protection

The CPT® Code 37215 refers to the transcatheter placement of intravascular stent(s) specifically in the cervical carotid artery. This procedure can be performed using either an open or percutaneous approach, which involves the insertion of a stent to treat stenosis, or narrowing, of the artery. The procedure includes angioplasty, if performed, and requires radiological supervision and interpretation. A key aspect of this procedure is the use of a distal embolic protection device, which is designed to prevent debris from traveling downstream during the stenting process. This is particularly important in the cervical carotid artery, where the risk of embolization can lead to serious complications, such as stroke. The procedure is typically indicated for patients with significant arterial blockage due to conditions like arteriosclerosis, and it aims to restore normal blood flow while minimizing the risk of embolic events. The detailed steps involved in the procedure ensure that it is performed safely and effectively, with careful consideration of the patient's anatomy and the specific characteristics of the stenosis being treated.
