Vascular surgery
About 37615: Major artery ligation in the neck
Reports surgical interruption of a major artery in the neck, such as for hemorrhage control or vascular control during a neck operation.
A surgeon exposes and ties off a major artery in the neck to stop or deliberately interrupt blood flow. The service may be performed in an operating room for control of bleeding after injury or during treatment of a neck condition. Vascular, trauma, or head-and-neck surgeons may perform it. The specific artery and operative purpose matter: carotid ligation services have more specific codes when the procedure matches those descriptions.
Report this code when the documented procedure is major-artery ligation in the neck and a more specific carotid ligation code does not describe the service. The operative report should identify the vessel, the site and extent of ligation, and the clinical reason. This major surgery has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

37615 billing questions
When should this code be chosen over a carotid ligation code?
Use this code for a major-artery ligation in the neck when the operation is not captured by a more specific carotid ligation service. Check the documented vessel and whether the procedure includes occlusion.
What operative details should the record include?
Document the artery ligated, the location and extent of the ligation, the reason for interrupting flow, and the operative work performed.
Does the 90-day global period include related postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be reported for ligation on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.
How are assistant and co-surgeon services handled?
An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
What happens if another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
