About 37765: Stab phlebectomy of leg veins
Reports removal of varicose tributary veins from one leg by stab phlebectomy when the procedure uses 10–20 incisions.
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.

37765 billing questions
How do I choose between 37765 and 37766?
Use 37765 for 10–20 incisions on one leg and 37766 when more than 20 incisions are used. Count incisions, not the number of vein segments removed.
Can I report this code for both legs?
The code describes treatment of one leg. For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%.
Are postoperative visits separately payable?
Related postoperative visits during the 10-day global period are included in the procedure.
How does the multiple-procedure reduction affect another same-session procedure?
When procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.
Can an assistant or co-surgeon be reported?
An assistant at surgery is not paid under the statutory restriction. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
