Vascular surgery
About 35538: Aortobi-iliac vein bypass graft
Reports an aortobi-iliac arterial bypass using a vein conduit to route blood from the aorta to both iliac arteries.
A vascular surgeon performs this open bypass by connecting a vein conduit between the aorta and both iliac arteries, creating a route around diseased or obstructed aortoiliac segments. The operation is performed in a surgical setting and may be considered for aortoiliac occlusive disease when revascularization to both iliac targets is needed. The bilateral iliac destination distinguishes this reconstruction from bypasses ending at one iliac or at the femoral arteries.
Report the code for the aorta-to-both-iliac vein bypass actually performed; the operative report should identify the conduit and both distal target arteries. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and related postoperative care. For other procedures performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate because bilateral anatomy is inherent. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35538 billing questions
How is this different from an aortobifemoral bypass?
This reconstruction terminates at both iliac arteries. An aortobifemoral bypass has distal targets in both femoral arteries.
Does the code describe a vein conduit?
Yes. This code is in the vein-graft bypass series; the operative report should support the conduit used.
Should modifier 50 be appended?
No. The code describes the bypass to both iliac arteries, so the bilateral anatomy is built into the service.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% multiple-procedure reduction.
