What 35602 covers
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.
