What 37765 covers
A surgeon removes superficial varicose tributary veins through small skin incisions, commonly using a hook to deliver and extract the vein segments. Vascular surgeons and other surgeons who treat venous disease perform the procedure for symptomatic or otherwise clinically treated varicosities, often in an office procedure room or outpatient operating setting. The code covers one leg when 10–20 incisions are used; the incision count, rather than the number of vein segments removed, distinguishes it from the higher-count sibling.
Document the treated leg, the varicose tributaries addressed, and the number of incisions. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeons require supporting documentation, and team surgery is not permitted.
