About 35563: Iliac-to-iliac vein bypass graft

Reports an open arterial bypass using a vein conduit to route blood between iliac arteries when the native iliac pathway is unusable.

Code 35563 represents an open arterial bypass using a vein conduit, with the connection running from one iliac artery to another. Vascular surgeons perform this operation in an operating room to route blood around diseased, obstructed, or otherwise unusable iliac arterial segments. The operative report should identify the donor and recipient iliac vessels, the bypass route, and the vein conduit; a connection from the aorta or to a femoral artery is a different route.

Select the code from the actual inflow and outflow vessels and the conduit used, not from the diagnosis alone. CMS assigns this major surgery a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. A bilateral procedure reported with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

35563 billing questions

When is 35563 the right bypass code?

Use it when the bypass connects one iliac artery to another and uses a vein conduit. Identify both vessels and the conduit in the operative report.

How does 35563 differ from 35663?

The route is iliac-to-iliac for both, but 35563 is for a vein conduit; 35663 is used for a conduit other than vein.

Would an aorta-to-iliac bypass be reported with 35563?

No. 35563 describes an iliac-to-iliac route; a bypass involving the aorta and iliac artery is represented by a different route-specific code.

What postoperative care is included in the global period?

The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

How are multiple procedures and bilateral reporting handled?

For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. A bilateral procedure reported with modifier 50 is paid at 150%.
