What 35612 covers
This operation creates a graft connection between the right and left subclavian arteries to route blood around an obstructed or otherwise unusable segment. Vascular surgeons may perform it for selected patients with subclavian artery occlusive disease when revascularization from the opposite subclavian artery is appropriate. The graft uses a conduit other than vein, commonly a prosthetic graft. The operative report should identify both arterial endpoints and describe the bypass performed.
Report this code when the bypass connects the subclavian artery on one side to the subclavian artery on the other, rather than using a carotid, axillary, or vertebral endpoint. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. A bilateral procedure reported with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose
- 35606Arterial bypassCarotid to subclavian
- Use 35606 when the bypass runs between a carotid artery and a subclavian artery. This code requires subclavian arteries on both sides as the endpoints.
- 35616Arterial bypassSubclavian to axillary
- Use 35616 when the bypass connects a subclavian artery to an axillary artery, not the two subclavian arteries.
- 35650Arterial bypassAxillary to axillary
- Use 35650 for a bypass between the axillary arteries. This code identifies a subclavian-to-subclavian connection.
- 35645Arterial bypassSubclavian to vertebral
- Use 35645 when a subclavian artery is connected to a vertebral artery; it is not a subclavian-to-subclavian bypass.
35612 billing questions
How is this different from a carotid-to-subclavian bypass?
This code is for a graft connecting the right and left subclavian arteries. A bypass using a carotid artery as one endpoint is coded to the code for that endpoint configuration.
Does the bypass use a vein graft?
No. This code describes a bypass using a conduit other than vein. The operative report should support the conduit used.
What documentation supports reporting this code?
Document the indication, the conduit, and the subclavian artery on each side as the bypass endpoints. The operative report should make clear that the graft connects the two subclavian arteries.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period. The surgeon's related routine follow-up is not separately reported as another service.
How are multiple procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction. A bilateral procedure reported with modifier 50 is paid at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeons are paid only when supporting documentation is submitted; 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.
