How To Use CPT Code 37215

CPT 37215 describes the placement of an intravascular stent in the cervical carotid artery, either through an open incision or percutaneously, with the use of distal embolic protection. This article will provide an overview of CPT code 37215, including its official description, the procedure involved, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples.

1. What is CPT Code 37215?

CPT 37215 is used to describe the placement of an intravascular stent in the cervical carotid artery. This procedure can be performed either through an open incision or percutaneously, depending on the provider’s preference and the patient’s specific condition. The placement of the stent is guided by imaging techniques, and an embolic protection device is used to prevent any detached blood clots from causing further complications. The purpose of this procedure is to treat carotid artery stenosis, which is the narrowing of the artery.

2. Official Description

The official description of CPT code 37215 is: ‘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.’

3. Procedure

1. The provider begins by preparing the patient and administering anesthesia, ensuring their comfort and safety throughout the procedure.
2. There are two approaches that the provider can choose from: an open incision or a percutaneous approach. The choice depends on the provider’s preference and the patient’s specific condition.
3. Using imaging guidance, the provider inserts a guide wire through the incision or puncture site and navigates it to the cervical carotid artery.
4. An embolic protection device is then placed through a catheter and positioned beyond the site of stenosis to capture any detached blood clots.
5. The provider may perform an angioplasty, which involves removing plaque from the lining of the artery or widening the vessel lumen using a balloon or laser.
6. Once the stenosis has been addressed, the provider places the intravascular stent across the narrowed portion of the cervical carotid artery.
7. Confirmation of the stent’s position is done using angiography or other imaging techniques.
8. The catheter is removed, and the puncture site is closed either by compression or sutures, depending on the approach used.
9. The patient’s vital signs and stability are monitored post-procedure.
