Vascular intervention
About 37217: Retrograde innominate or thoracic carotid stenting
Reports retrograde endovascular stenting of an innominate artery or intrathoracic common carotid artery lesion, including angioplasty when performed.
This service places an intravascular stent in the innominate artery or intrathoracic portion of the common carotid artery using a retrograde approach. It is typically performed by a vascular surgeon, interventional radiologist, or another appropriately trained endovascular specialist in a hospital setting. Access may be open or percutaneous; the approach proceeds back toward the aortic arch from the target vessel. Angioplasty, when performed, and the procedure’s radiological supervision and interpretation are included.
Report 37217 for the treated vessel and retrograde approach, not for a stent in the cervical carotid artery. The operative report should identify the lesion’s arterial location, access method, direction of treatment, and stent placement. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. 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.

37217 billing questions
How does 37217 differ from 37218?
Both address stenting of the innominate artery or intrathoracic common carotid artery. Use 37217 for the retrograde approach and 37218 for the antegrade approach.
Can angioplasty be billed separately with 37217?
Angioplasty performed as part of the stenting service is included. The code also includes the radiological supervision and interpretation for the intervention.
When is 37217 more appropriate than 37215 or 37216?
37217 is for retrograde stenting in the innominate artery or intrathoracic common carotid artery. Codes 37215 and 37216 address stenting in the extracranial carotid artery and distinguish use of embolic protection.
What documentation supports the retrograde approach?
Document the treated artery and lesion location, access method, direction of catheter treatment, and stent placement. The record should make clear that the target is the innominate artery or intrathoracic common carotid artery.
How does Medicare handle bilateral reporting and multiple procedures?
Bilateral reporting with modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted under the listed CMS rules.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
