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.

35341 billing questions

How is 35341 distinguished from 35331?

35341 is for endarterectomy of an abdominal renal, visceral, or aortic branch artery. 35331 is for endarterectomy of the aorta itself.

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?

Document the specific abdominal branch artery, the obstructive disease treated, and the operative work. The record should make clear that the surgeon performed an endarterectomy rather than another revascularization method.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period. The global period is tied to the operation, not just the date of surgery.

Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

How is bilateral 35341 reported?
