Summary & Overview
CPT 31755: Trachea-to-Pharynx Surgical Connection
CPT code 31755 covers a surgical tracheal procedure performed to create a connection between the trachea and the pharynx. The code captures a complex airway reconstruction that is clinically significant for patients with airway disruption, malignancy, trauma, or congenital anomalies requiring reestablishment of aerodigestive continuity. Nationally, this code represents advanced otolaryngology/thoracic surgical care with implications for hospital resource use, perioperative risk management, and specialized postoperative airway support.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for CPT code 31755, common sites of service, and the types of providers likely to bill the code. The publication summarizes available benchmarks where provided and flags areas where input data is not available. It also outlines policy and billing considerations relevant to high-acuity airway surgeries, including typical service settings and the clinical rationale for coding this procedure.
This executive summary is intended for hospital administrators, coding professionals, and payers seeking a concise national perspective on CPT code 31755 and its role in surgical airway management.
Billing Code Overview
CPT code 31755 describes a surgical procedure on the trachea intended to create a connection between the trachea and the pharynx. This procedure involves surgical reconstruction or anastomosis of the airway to establish or restore communication with the pharyngeal lumen.
-
Service type: Surgical airway reconstruction
-
Typical site of service: Operating room or inpatient surgical setting
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with severe upper airway obstruction or complex laryngotracheal injury who requires creation of a surgical connection between the trachea and pharynx to restore airway patency, enable oral or pharyngeal access, or bypass a high airway lesion. Patients often present with progressive dyspnea, stridor, repeated aspiration events, or failed decannulation after prolonged tracheostomy. Relevant history includes prior neck surgery, radiation, infection (e.g., necrotizing tracheitis), tumor invasion of the laryngotracheal complex, or traumatic tracheal disruption.
The clinical workflow includes preoperative airway evaluation (flexible nasopharyngoscopy, bronchoscopy, imaging such as CT neck), multidisciplinary planning with otolaryngology/head and neck surgery and thoracic surgery as indicated, informed consent addressing airway risk, operative creation of the tracheopharyngeal anastomosis under general anesthesia with possible neck exploration and reconstruction, intraoperative airway management (endotracheal tube or tracheostomy), and postoperative care in a monitored setting for airway edema, anastomotic integrity, aspiration risk, and speech/swallow rehabilitation. Typical site of service is an inpatient operating room within a tertiary or academic medical center; some complex cases require intensive care unit postoperative monitoring.
