CPT code 36482 denotes endovenous chemical adhesive ablation of an incompetent extremity vein and is reported for the first vein treated. The code captures a minimally invasive, catheter-based procedure that delivers a chemical adhesive to close refluxing superficial veins and is an increasingly utilized alternative to thermal ablation and surgical stripping. Nationally, this code matters because it maps to outpatient vascular care, impacts ambulatory surgical workflows, and informs payer coverage and coding guidance for varicose vein management.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for chemical adhesive ablation, typical sites of service, and common modifiers associated with procedural reporting (modifier list provided in the input). The publication summarizes benchmarks and payment considerations where available, highlights coding nuances specific to reporting the first vein treated, and outlines areas where billing practitioners and revenue cycle teams should confirm payer-specific coverage rules.

This national summary provides the clinical framing and coding definition needed by clinicians, billing staff, and policy analysts to understand where CPT code 36482 fits within venous intervention services and how it may influence outpatient procedural coding and reimbursement workflows.
