About 37780: Revision of previously treated leg veins
Reports surgical revision of previously treated leg veins, typically for recurrent or residual varicosities after an earlier vein ligation.
This service involves surgically revising a previously treated vein in the leg, often when varicosities recur or persist after prior ligation. A vascular surgeon or other qualified surgeon may identify and revise the affected vein, with ligation, division, or excision as needed. These procedures are generally performed in an operating-room setting; the operative report should identify the prior treatment and the vein or recurrent disease addressed.
Report the code for revision of the previously treated leg vein, rather than for primary treatment of a new varicose-vein cluster. Documentation should support the recurrent or residual condition and describe the revision performed. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is barred; co-surgeons require supporting documentation, and team surgery is not permitted.
