About 37606: Common or internal carotid ligation with occlusion
Reports surgical ligation or banding that occludes the common or internal carotid artery, such as for selected bleeding control or planned vessel sacrifice.
Code 37606 describes open surgical ligation or banding of the common or internal carotid artery when the operation closes the vessel. Vascular or head-and-neck surgeons may perform it in an operating room to control difficult carotid bleeding or injury, or as planned vessel sacrifice in selected tumor-related care. It is distinct from procedures on the external carotid artery and from ligation or banding that does not occlude the vessel.
Choose the code from the operative report: it should identify the common or internal carotid artery and document ligation or banding with occlusion. The 90-day global includes 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 other procedures are subject to the standard 50% reduction. Do not append modifier 50; a bilateral adjustment is not used. CMS allows payment for an assistant at surgery, but does not permit co-surgeons or team surgery.

37606 billing questions
How is 37606 different from 37605?
Use 37606 when the documented ligation or banding occludes the common or internal carotid artery. Code 37605 describes the related service without occlusion.
What operative documentation supports 37606?
The report should identify the common or internal carotid artery and describe the ligation or banding and resulting occlusion. It should also explain the clinical reason for the procedure.
Should modifier 50 be used for bilateral work?
No. CMS does not apply a bilateral adjustment to this code, and modifier 50 is inappropriate.
Can an assistant surgeon be paid for this procedure?
CMS permits payment for an assistant at surgery. Co-surgeons and team surgery are not permitted for this code.
How does the multiple-procedure reduction affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction.
What postoperative care is included in the global period?
The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.
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.
