What 35632 covers

This open vascular operation reroutes blood from an iliac artery to the celiac artery using a conduit other than vein, commonly a prosthetic graft. Vascular surgeons may perform it for celiac artery occlusive disease affecting blood flow to the upper abdominal organs, including in selected patients with chronic mesenteric ischemia. It is performed in an operating room, not as an endovascular intervention.

The operative report should identify the iliac inflow artery, celiac recipient, conduit material, and indication. Choose a different bypass code when the inflow is the aorta or the graft terminates at another visceral artery. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 receives bilateral payment at 150%. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

35631Aortic bypass
Select 35632 when the bypass begins at an iliac artery and ends at the celiac artery. Select 35631 for aortic inflow to the celiac, mesenteric, or renal arteries.
35633Arterial bypass
Both use iliac inflow, but 35633 identifies a mesenteric artery destination; 35632 identifies the celiac artery.
35634Arterial bypass
Both use iliac inflow, but 35634 identifies a renal artery destination; 35632 identifies the celiac artery.

35632 billing questions

How is this different from 35631?

This code uses an iliac artery as the bypass inflow and the celiac artery as the destination. Code 35631 is for aortic inflow to specified visceral arteries, including the celiac artery.

Does the conduit have to be a prosthetic graft?

The code is for a conduit other than vein. A prosthetic graft is common, but the operative report should establish the conduit used.

What documentation supports this code?

Document the iliac inflow, celiac artery destination, conduit material, and clinical reason for the bypass. The documented target helps distinguish this from iliac-to-mesenteric or iliac-to-renal bypass.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How are other same-session procedures and surgical assistants handled?

For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
