Summary & Overview
CPT 38382: Thoracic Duct Repair via Abdominal Approach
CPT code 38382 identifies surgical repair of the thoracic duct via an abdominal approach, commonly performed to control chyle leakage after penetrating thoracic trauma. This procedure is clinically important for preventing ongoing chylous drainage, nutritional depletion, and infection risk following thoracic duct injury. Nationally, correct coding for this operation supports accurate surgical case capture, outcomes tracking, and appropriate reimbursement for complex thoracic and vascular-surgical care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when CPT code 38382 is used, the typical site of service, and common billing considerations. The publication also outlines benchmark expectations and policy-relevant points that affect coverage and claims adjudication for thoracic duct repair procedures. Clinical teams, coding professionals, and policy analysts will gain a clearer view of how CPT code 38382 fits into surgical service lines and what areas warrant attention for documentation and payer discussions.

Billing Code Overview
CPT code 38382 describes a surgical procedure to repair the thoracic duct through an abdominal incision. The procedure typically involves identifying the thoracic duct and either suturing the injured duct or ligating it to stop chyle leakage. The most common clinical indication is penetrating chest trauma that damages the thoracic duct.
Service type: Invasive surgical repair of the thoracic duct
Typical site of service: Operating room or surgical suite, accessed via an abdominal incision (inpatient or outpatient surgical setting as clinically indicated)
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who presents after penetrating thoracic trauma (e.g., stab or gunshot wound) with chylothorax or active chyle leak identified on imaging or chest tube output. The patient is evaluated in the emergency department and admitted to a trauma or thoracic surgery service. Initial management includes hemodynamic stabilization, chest tube placement for pleural drainage, chest imaging (CT chest), and laboratory assessment. When conservative measures (drainage, dietary modification, medium‑chain triglyceride diet or NPO with total parenteral nutrition) fail or when the leak is large/continuous or associated with ongoing bleeding from the thoracic duct injury, the thoracic surgery team schedules operative repair.
In the operating room under general anesthesia, the surgeon gains abdominal access with an upper abdominal incision to approach the thoracic duct at the diaphragmatic hiatus or retroperitoneal/transdiaphragmatic route. The duct is identified, and repair is performed by suture ligation or complete ligation/tying off of the duct to stop chyle flow. Intraoperative adjuncts may include lymphangiography or use of fatty meal to enhance leak visualization. Postoperatively the patient is monitored in a surgical unit with chest tube management, dietary restrictions, and serial evaluation for resolution of chyle leak. Typical payors involved in authorization and claims include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
