CPT code 35045 denotes open surgical repair of an aneurysm or pseudoaneurysm of the radial or ulnar artery via a forearm incision, with direct arterial repair or graft placement. This code is clinically important because it captures a targeted vascular reconstruction procedure for upper-extremity arterial pathology that can affect limb perfusion and limb-sparing decision-making. Accurate coding supports appropriate payment for vascular surgeons and surgical teams and informs utilization tracking for peripheral vascular repair.

Key payers in this national overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and which payer populations are addressed. The publication summarizes expected service line placement, common procedural modifiers where applicable, and comparisons to related vascular repair services when available.

This report helps billing managers, vascular surgeons, and policy analysts understand where CPT code 35045 fits within vascular surgery coding, what clinical situations trigger its use, and which payers underlie national coverage and reimbursement patterns. Data not available in the input is noted where relevant, and the focus remains on clinical and billing context rather than individualized clinical guidance.
