What 37218 covers

This service treats a lesion in the intrathoracic common carotid or innominate artery by placing an intravascular stent in an antegrade direction. Angioplasty of the treated vessel is included when performed. Vascular surgeons and interventional specialists typically perform the procedure in a hospital setting, using catheter-based imaging to guide treatment of a proximal supra-aortic vessel lesion.

Select this code when the treated vessel and antegrade approach meet its scope; distinguish it from retrograde treatment and stenting of the cervical carotid artery. The operative report should identify the target vessel, approach, lesion, stent placement, and any angioplasty performed. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
