Vascular surgery
About 35637: Aorta-to-iliac bypass with non-vein graft
Reports open bypass from the abdominal aorta to one iliac artery using a non-vein graft, typically to restore flow in aortoiliac occlusive disease.
This code describes an open vascular bypass that routes blood from the abdominal aorta to one iliac artery using a conduit other than vein, commonly a prosthetic graft. A vascular surgeon typically performs it in a hospital operating room for significant aortoiliac occlusive disease when direct flow to the iliac circulation needs to be restored. The code is distinguished by the aortic inflow, the iliac outflow, and the non-vein conduit.
Choose the code from the operative report’s documented inflow, outflow, and conduit; a bypass to both iliac arteries or to a femoral artery has a different code. The report should support the treated vessels and graft used. This major operation has a 90-day global period that includes the day-before preoperative visit and related postoperative care during that period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35637 billing questions
How is this code distinguished from 35638?
35637 is for a bypass from the aorta to one iliac artery. 35638 describes the aortic bypass when both iliac arteries are the outflow targets.
Should modifier 50 be reported?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate for its descriptor and anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
What documentation supports code selection?
The operative report should identify the aortic inflow, the iliac outflow target, and use of a conduit other than vein. These details distinguish this service from bypasses to both iliac arteries or to a femoral artery.
How are other same-session procedures paid?
The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to the standard multiple-procedure reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
