CPT code 37615 denotes surgical ligation of a ruptured arterial vessel in the neck due to injury or trauma. It captures a time-sensitive, high-acuity vascular operation performed to control life-threatening hemorrhage and stabilize patients. Nationally, correct coding for this intervention affects hospital and surgical reporting, trauma registry records, and high-acuity reimbursement pathways.

Key payers examined include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise outline of the clinical context for the procedure, typical sites of service, and the types of documentation elements that support coding and claim submission. The publication also summarizes benchmark considerations, common billing modifiers encountered in practice, and potential policy implications for payers and providers handling emergency vascular trauma care.

This analysis is intended for hospital coding managers, trauma surgeons, revenue cycle staff, and policy analysts seeking a clear, national-level briefing on CPT code 37615 — what it represents clinically, why it matters for coding and billing, and where to focus documentation and administrative attention when this emergent procedure is performed.
