Vascular surgery
About 37660: Common iliac vein ligation
Reports operative ligation of a common iliac vein when the surgeon intentionally interrupts flow through that major pelvic vein.
This service involves surgically identifying and tying off a common iliac vein to stop or intentionally interrupt venous flow. It may arise during vascular, trauma, or complex pelvic surgery, such as when the vein must be controlled for bleeding or another operative indication. Vascular, trauma, or other surgeons performing the operation report the service based on the vessel actually ligated, not merely the location of the incision.
The operative report should identify the common iliac vein, document the reason for ligation, and describe the procedure and side; document both sides when bilateral. This major surgery code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be allowed; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
