CPT code 35694 represents a surgical arterial bypass that exposes and divides the subclavian artery and anastomoses it to the carotid artery to circumvent arterial obstruction and improve blood flow. This complex vascular reconstruction is nationally relevant due to its role in limb and cerebral perfusion management, implications for surgical resource use, and interactions with payer coverage policies for vascular surgery.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, typical sites of service, and the kinds of benchmarks and policy guidance commonly associated with high-complexity vascular surgical codes. The publication outlines common modifiers used with the code and highlights the clinical scenarios that drive utilization.

The analysis provides national-level context for clinicians, coding professionals, and policy analysts: clinical indications and service setting expectations, benchmarking considerations for use and reimbursement, and areas where payer policies and prior authorization practices frequently apply. Data not provided in the input are noted as unavailable where relevant; the focus remains on clarifying the code's clinical meaning and administrative attributes for stakeholders working with vascular surgery claims.
