Vascular intervention
About 37218: Antegrade intrathoracic carotid stenting
Reports antegrade stent placement in the intrathoracic common carotid or innominate artery, including angioplasty when performed during treatment.
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.

37218 billing questions
How does 37218 differ from 37217?
The distinction is the direction of treatment: 37218 is for an antegrade approach, while 37217 is for a retrograde approach to the specified proximal vessel.
Is angioplasty of the treated vessel reported separately?
Angioplasty performed as part of the stent treatment is included in 37218.
When should 37215 or 37216 be considered instead?
Those codes describe stenting in the cervical carotid artery. Use 37218 for antegrade treatment of the intrathoracic common carotid or innominate artery.
What documentation supports reporting 37218?
Document the treated vessel and lesion, the antegrade approach, and the stent placement; also describe angioplasty if performed.
Can an assistant-at-surgery be paid for this procedure?
CMS assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
