About 35602: Carotid-to-contralateral carotid bypass
Open bypass connecting carotid arteries across the neck to restore or maintain cerebral blood flow in selected carotid occlusive or reconstructive cases.
Code 35602 represents open bypass reconstruction that carries arterial blood from a carotid artery on one side of the neck to a carotid artery on the opposite side through an interposed conduit. Vascular surgeons perform it in the operating room when a cross-neck route is selected to restore or maintain cerebral inflow, including selected complex carotid occlusive or reconstructive cases. The operation establishes a new path between the vessels; it differs from removing plaque from a carotid artery or connecting a carotid to a subclavian or vertebral artery.
Report the code when the operative note documents the donor and recipient carotid arteries and the completed contralateral bypass, not merely vessel exposure or a planned graft. Documentation should identify the indication, conduit, and anastomoses, along with any additional procedures performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35602 billing questions
How does 35602 differ from 35601?
35602 connects carotid arteries on opposite sides of the neck. 35601 describes a bypass from a common carotid artery to the internal carotid artery on the same side.
When is modifier 50 appropriate?
Do not append modifier 50 to 35602. CMS identifies bilateral adjustment as inappropriate for this code.
What operative details support reporting 35602?
Document the carotid donor and recipient vessels, the contralateral route, the conduit and anastomoses, and the clinical reason for the 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.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
