HCPCS 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

AI EXPLANATION: Carotid artery stent placement is a minimally invasive procedure to open narrowed arteries in the neck that supply blood to the brain. A physician guides a thin tube called a catheter to the blockage, gently expands the artery—often using a small balloon—and inserts a permanent mesh tube, known as a stent, to hold the vessel open. A specialized temporary filter device is also deployed during the procedure to capture loose particles and help protect the brain.
