About 35515: Subclavian-to-vertebral arterial bypass
Reports an open bypass routing blood from the subclavian artery to a vertebral artery to address compromised vertebral circulation.
Code 35515 represents an open bypass that routes arterial blood from the subclavian artery to a vertebral artery, creating an alternate pathway around an obstructed or inadequate segment. Vascular surgeons perform it in the operating room for selected patients with compromised vertebral circulation, including cases associated with subclavian steal physiology. The defining feature is the named inflow and outflow vessels, not simply treatment of arm ischemia or any operation near the neck.
Report this code when operative documentation supports the subclavian-to-vertebral bypass; distinguish it from bypasses whose outflow is the carotid, axillary, or another vessel. Document laterality, anastomotic endpoints, indication, and the bypass performed. The 90-day global includes the day-before preoperative visit and related postoperative care through day 90. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral work, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

35515 billing questions
How do I distinguish 35515 from a carotid-to-vertebral bypass?
Choose 35515 when the bypass runs from the subclavian artery to the vertebral artery. A carotid-to-vertebral bypass has a different inflow vessel and is represented by 35508.
Which operative details support reporting 35515?
The operative report should identify the subclavian inflow, vertebral outflow, laterality, and the bypass performed. The named vessel endpoints distinguish this service from nearby bypass procedures.
How does the 90-day global affect postoperative reporting?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How is 35515 handled when other procedures occur in the same session?
The highest-valued procedure is paid in full, and other procedures are paid at 50%. For bilateral work, modifier 50 is paid at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
