About 35533: Axillary-femoral-femoral vein bypass
Reports an axillary-to-bilateral femoral arterial bypass using a vein graft, often to restore lower-extremity blood flow when aortic reconstruction is unsuitable.
Code 35533 describes an extra-anatomic bypass that carries blood from an axillary artery to a femoral artery and across to the opposite femoral artery, using a vein graft. Vascular surgeons may perform this reconstruction for severe aortoiliac occlusive disease when direct aortic reconstruction is not appropriate. The operative report should establish the axillary inflow, both femoral targets, and vein conduit used.
Select this code for the complete axillary-femoral-femoral route, rather than a single axillary-femoral bypass or a femoral-femoral bypass alone. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. When bilateral reporting with modifier 50 is appropriate, CMS pays at 150%. Assistant-at-surgery services may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

35533 billing questions
How does 35533 differ from 35521?
35533 covers an axillary inflow with a bypass continuing to both femoral arteries. 35521 describes an axillary-to-femoral bypass with a single femoral target.
Does the code describe a vein graft?
Yes. The bypass uses a vein conduit; the operative report should identify the conduit and the full bypass route.
Is 35533 the right code for a femoral-femoral bypass alone?
No. A femoral-femoral bypass without the axillary inflow is a different route; 35558 is the related vein-graft code to compare.
What should the operative report document?
Document the axillary artery used for inflow, both femoral anastomosis sites, and the vein conduit. These details distinguish the full route from a single-limb bypass.
What postoperative care is included?
The 90-day global period 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-surgeons are paid only with supporting documentation; team surgery is not permitted.
