CPT code 34710: Graft extension, delayed, initial vessel2026 Medicare rate & RVUs

Medicare pays $722.46 for 34710 nationally in a facility.

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

What 34710 covers

This service covers a later procedure to place an extension prosthesis after endovascular repair of the infrarenal aorta or an iliac artery. The extension may address a seal problem or endoleak after the original repair. The vascular surgeon uses imaging to assess the target zone, measure the vessel, and guide placement; the code includes associated radiological supervision and interpretation. It is reported for the initial vessel treated in the delayed procedure, not for extension placement performed as part of the original repair.

The operative report should identify the prior endovascular repair, the reason for the delayed extension, the vessel treated, and the imaging and placement performed. Report 34711 for each additional vessel treated. 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 others at 50%. Assistant-at-surgery payment may be made, and co-surgeons are permitted; team surgery is not permitted. The code is not adjusted bilaterally, and modifier 50 is inappropriate.
