Vascular surgery

About 35633: Ilio-mesenteric bypass graft

Reports open bypass using a non-vein graft from an iliac artery to a mesenteric artery to restore blood flow in mesenteric occlusive disease.

This code describes open arterial revascularization using a graft other than vein to carry blood from an iliac artery to a mesenteric artery, commonly the superior mesenteric artery. Vascular surgeons may perform it for mesenteric arterial occlusive disease when an open bypass is selected. The operative report should establish the inflow artery, mesenteric outflow target, conduit, and indication for revascularization.

Choose this code for the iliac-to-mesenteric route; a different inflow or outflow site points to a different bypass code. Document the graft path and each bypass performed during the session. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 applies to a bilateral procedure, paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
