CPT 32815: Surgical Closure of Bronchial Fistula

CPT code 32815 denotes the surgical closure of a bronchopleural or bronchocutaneous fistula, a thoracic procedure to repair an abnormal communication involving a bronchus and adjacent structures. This code is clinically significant because bronchial fistulae can lead to serious respiratory compromise, infection, and prolonged hospitalization; accurate coding supports appropriate procedural tracking and hospital utilization reporting nationwide. Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for 32815, common sites of service, and the national relevance of coding for complex thoracic surgical procedures. The publication summarizes typical payer coverage patterns and benchmarking considerations where available, highlights policy and reimbursement notes that affect procedural valuation, and details clinical factors that influence coding and billing for fistula closure. Additional sections provide guidance on documentation elements that support coding, common modifiers associated with surgical services (listed separately), and references to related thoracic surgical procedures. Data not available in the input is identified where applicable.

Billing Code Overview

CPT code 32815 describes the surgical closure of a bronchopleural or bronchocutaneous fistula — a large abnormal passage or communicating tract between a bronchus and another structure such as the pleural surface of the lung or the cutaneous surface of the thoracic wall. This procedure involves operative repair to eliminate the pathological connection and restore normal anatomic separation.

Service type: Surgical procedure for fistula repair
Typical site of service: Inpatient or outpatient surgical setting, commonly performed in an operating room with thoracic surgery expertise

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a bronchopleural or bronchocutaneous fistula following pulmonary surgery (e.g., lobectomy) or necrotizing lung infection. The patient presents with persistent air leak, recurrent pneumothorax, empyema, chronic drainage from the chest wall, or respiratory compromise despite conservative measures. Preoperative workflow includes imaging (CT chest), bronchoscopy to localize the fistula, pulmonary and infectious disease evaluation, optimization of comorbidities (pulmonary, cardiac), informed consent, and planning for operative approach under general anesthesia. Intraoperative steps typically involve thoracotomy or thoracoscopic access, identification of the bronchial defect or tract, debridement of infected tissue, closure of the fistula with sutures and buttressing tissue (e.g., muscle or pleural flap), and chest tube placement for postoperative drainage. Postoperative management includes chest tube management, respiratory support, antibiotics as indicated, monitoring for recurrent air leak or infection, and follow-up imaging and pulmonary function assessment.

Coding Specifications
