About 35331: Aortoiliac artery endarterectomy
Open aortoiliac endarterectomy removes obstructive plaque from the aorta and iliac artery to restore blood flow in symptomatic occlusive disease.
A vascular surgeon performs this open operation to remove atherosclerotic material obstructing the aortoiliac arterial pathway. It is used for selected patients with aortoiliac occlusive disease causing symptoms such as limiting claudication or limb-threatening ischemia. The surgeon may use a patch to widen the treated vessel; that possibility is included in the procedure. The service is generally performed in a hospital operating room, rather than an office setting.
Report the code when the operative work is an endarterectomy involving the aortoiliac segment. The operative note should identify the treated artery or arteries, laterality, extent of plaque removal, and any patch repair. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the 90 days after surgery. 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. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
