What 35533 covers
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.

How to choose
- 35521Arterial bypass
- Use 35521 for an axillary-to-femoral bypass with one femoral target. 35533 includes the additional crossover to the opposite femoral artery.
- 35558Arterial bypass
- 35558 describes a femoral-femoral vein-graft bypass without axillary inflow. Choose 35533 when the bypass originates at the axillary artery and supplies both femoral arteries.
- 35633Arterial bypass
- The route is the same, but 35633 is for a graft made from material other than vein; 35533 is the vein-graft code.
- 35621Arterial bypass
- 35621 describes an other-than-vein axillary-to-single-femoral bypass. It differs from 35533 in both conduit type and the second femoral target.
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.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
