What 37785 covers
This code describes operative treatment of one leg’s varicose vein clusters by ligating, dividing, and/or excising the affected veins. A surgeon, often working in an outpatient setting, may use it when the targeted varicosities are clusters rather than a saphenous trunk treated by stripping. The operative report should identify the leg, the cluster locations, and the work performed.
Report one-leg treatment based on the procedure actually performed; distinguish cluster treatment from stab phlebectomy, for which incision counts guide code selection. 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% multiple-procedure reduction. Modifier 50 identifies bilateral surgery and is paid at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
