Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 34520 covers

A vascular surgeon creates a vein-graft pathway across the midline to reroute blood from an obstructed lower-extremity venous outflow into the opposite-side venous system. A typical clinical setting is chronic unilateral iliac venous obstruction when a crossover bypass, such as a Palma-Dale-type operation, is selected. The operative record should identify the obstruction, the veins used for inflow and outflow, the graft route, and the anastomoses.

Report this code for the crossover venous graft procedure, not simply for vein harvest or a valve repair. CMS assigns 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 procedure is paid in full and other procedures are subject to the standard 50% reduction. A bilateral procedure reported with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons are paid only with supporting documentation. Team surgery is not permitted.
