CPT® Code 37217

Transcatheter placement of intravascular stent(s), intrathoracic common carotid artery or innominate artery by retrograde treatment, open ipsilateral cervical carotid artery exposure, including angioplasty, when performed, and radiological supervision and interpretation

The CPT® Code 37217 refers to the transcatheter placement of intravascular stent(s) specifically in the intrathoracic common carotid artery or the innominate artery. This procedure is performed using a retrograde approach, which involves accessing the artery from the same side (ipsilateral) through an incision in the cervical region. The procedure includes the exposure of the cervical carotid artery, allowing for the insertion of an introducer sheath. Following this, a guidewire is introduced and advanced retrograde into the targeted artery. The use of angioplasty may be incorporated into the procedure to dilate any stenosed areas before the stent is placed. Radiological supervision and interpretation are integral components of this procedure, ensuring accurate placement and assessment of the stent. The overall goal of this intervention is to restore proper blood flow through the affected arteries, addressing conditions such as stenosis that may impede circulation. The procedure is comprehensive, involving multiple steps to ensure the successful deployment of the stent and the subsequent closure of the surgical site.
