Summary & Overview
CPT 38381: Thoracic Duct Repair via Thoracotomy or Sternotomy
CPT code 38381 represents surgical repair of the thoracic duct via a chest approach, typically by sternotomy or thoracotomy. The procedure is most often performed for penetrating chest trauma or other causes of thoracic duct disruption that produce chyle leaks, and it is a specialized thoracic surgical intervention with implications for inpatient surgical workflow and postoperative care. Nationally, thoracic duct repair is an infrequent but clinically significant procedure due to its role in resolving chyle leak–related morbidity and prolonged hospitalization.
Key payers relevant to coverage and reimbursement considerations include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The code is typically billed for hospital-based operative encounters in an operating room setting and is associated with thoracic surgery service lines.
Readers will find a concise summary of the clinical context for the procedure, typical site-of-service expectations, and an outline of common billing modifiers provided in the input. The publication offers benchmarks where available, notes on coding and billing context, and policy or payer considerations that affect coverage and claim adjudication. Data not provided in the input—such as specific ICD-10 diagnosis pairings, payer-specific reimbursement rates, and associated taxonomies—is identified as unavailable.
Billing Code Overview
CPT code 38381 describes repair of the thoracic duct performed through the chest by incising the breastbone (sternotomy) or ribs (thoracotomy). The procedure addresses injuries or disruptions to the thoracic duct, most commonly from penetrating chest trauma, to restore lymphatic continuity and prevent persistent chyle leak.
Service Type: Surgical — thoracic duct repair
Typical Site of Service: Inpatient or operating room within a hospital thoracic surgery setting
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who presents after penetrating thoracic trauma (e.g., stab wound or gunshot) with signs of persistent chylothorax such as milky pleural drainage, increasing chest tube output high in triglycerides, dyspnea, or hemodynamic instability. Initial evaluation includes chest radiography or CT chest and thoracostomy tube placement for pleural drainage. When conservative management (chest tube drainage, nil per os with total parenteral nutrition, or medium-chain triglyceride diet) fails or there is ongoing high-output chyle leak, the patient is taken to the operating room for surgical exploration. The procedure 38381 (repair of thoracic duct via thoracotomy or sternotomy) is performed by a cardiothoracic or thoracic surgeon under general anesthesia. Intraoperative steps include exposure of the mediastinum through incision of the sternum (median sternotomy) or thoracotomy, identification of the injured thoracic duct or lymphatic leak, and definitive repair or ligation of the duct, with attention to hemostasis and possible placement of chest drains. Postoperative workflow includes intensive monitoring of chest tube output, respiratory support as needed, nutritional management to limit chyle production, and coordination with inpatient case management for payer authorization and discharge planning with follow-up imaging or outpatient drainage assessment.
