Vascular surgery

About 35631: Aortic bypass to visceral and renal arteries

Reports open aortic bypass grafting to the celiac, mesenteric, and renal arteries when all three visceral and renal territories are revascularized.

A vascular surgeon performs an open bypass from the aorta to the celiac, mesenteric, and renal arteries using graft material other than vein. The operation may be used for complex occlusive disease affecting these arterial territories. It is typically performed in a hospital operating room, with the operative report identifying the aortic inflow, each distal target, and the graft material and configuration used.

Report this code when the documented bypass includes all three named target territories; a bypass from the aorta to only one of them is represented by a different code. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are reduced to 50%. For a bilateral service reported with modifier 50, payment is 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

35631 billing questions

When should this code be selected instead of an aortic bypass to one artery?

Use it when the operation documents bypass from the aorta to the celiac, mesenteric, and renal arteries. A bypass to only one of those targets is not this full three-territory service.

What operative details support reporting this code?

The operative report should identify the aorta as the inflow and document each of the three distal arterial target territories, along with the graft material and configuration.

Does the code represent the bypass to all three target territories?

Yes. The code represents the aortic bypass service involving the celiac, mesenteric, and renal arteries; the report should substantiate all three targets.

How is this code paid when other procedures are performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

Can assistant or co-surgeon services be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
