What 35341 covers
A vascular surgeon opens an abdominal branch artery, removes obstructive material from its inner wall, and may use a patch to restore the vessel’s lumen. The code covers endarterectomy of arteries such as the renal or visceral branches of the aorta. These operations are generally performed in a hospital operating room for selected patients with significant arterial obstruction, including cases involving impaired blood flow to an abdominal organ.
Report the code when the operative documentation supports endarterectomy of an abdominal aortic branch; the named artery, operative approach, and work performed should be clear. A patch graft, when used as part of the endarterectomy, is included in the service. The procedure has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

Is a patch graft separately reported?
A patch used as part of the endarterectomy is included in the service. The operative report should describe the artery treated and the endarterectomy performed.
What documentation supports reporting 35341?
