About 37605: Internal or common carotid artery ligation
Surgical ligation of an internal or common carotid artery is reported when the surgeon ties off the vessel for a selected vascular or bleeding problem.
The surgeon exposes and ties off an internal or common carotid artery, interrupting flow through the treated vessel. This uncommon open neck operation may be performed for selected carotid injury, uncontrolled bleeding, or an aneurysm when vessel ligation is the intended treatment. Vascular, trauma, or head-and-neck surgeons may perform it in an operating room, generally in a facility setting.
Report 37605 when the operative note supports ligation of the internal or common carotid artery; document the specific artery and the procedure performed. Distinguish the external carotid ligation code and the related carotid code whose descriptor specifies occlusion. The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate for this descriptor and anatomy. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

37605 billing questions
How is 37605 distinguished from 37600?
37605 is for ligation of the internal or common carotid artery. Use 37600 when the external carotid artery is the vessel ligated.
When should 37606 be considered instead?
The 37606 descriptor specifies occlusion with internal or common carotid artery ligation. Select it only when the operative documentation supports that added descriptor detail.
Can modifier 50 be reported for both sides?
No. The descriptor and anatomy make modifier 50 inappropriate for bilateral adjustment.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
