CPT 31770 Airway Repair Reimbursement & Policy | OpenPayer

Summary & Overview

CPT 31770: Repair of Airway with Graft or Patch

CPT code 31770 represents surgical repair of an airway using a graft or patch to reconstruct or reinforce the trachea or major airway. This procedure is clinically significant for patients with airway defects, trauma, stenosis, or structural compromise that require operative reconstruction to restore breathing and prevent long-term morbidity. Nationally, airway reconstruction procedures have implications for surgical specialty capacity, hospital resource use, and perioperative care protocols.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how the service is billed, typical sites of service, and the clinical context in which the code is used. The publication outlines reimbursement benchmarks, common billing modifiers, and payer coverage considerations where available. It also summarizes policy updates and coding guidance relevant to airway reconstruction procedures.

This resource is intended for coding professionals, surgical teams, and revenue-cycle staff seeking a national perspective on coding and billing for airway repair with graft or patch. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 31770 describes repair of an airway with a graft or patch. This procedure involves surgical reconstruction or reinforcement of the trachea or major airway using a graft or patch material to restore patency, structural integrity, or function.

Service type: Surgical airway reconstruction using graft or patch
Typical site of service: Hospital operating room or specialized surgical center

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult who presents with symptomatic tracheal or bronchial defect from trauma, tumor resection, stenosis revision, or failed prior airway repair. Example: a 52-year-old male undergoes segmental tracheal resection for a recurrent laryngeal papilloma with a resultant full-thickness airway defect repaired intraoperatively using an autologous graft patch to restore airway integrity. The clinical workflow includes preoperative assessment with airway imaging (CT or bronchoscopy), anesthesia planning for secure airway control (often through endotracheal tube exchange or rigid bronchoscopy), intraoperative exposure of the airway, debridement of nonviable tissue, placement and suturing of the graft or patch to reconstruct the airway wall, leak testing via positive-pressure ventilation and bronchoscopy, and postoperative monitoring in a step-down or ICU setting for airway patency, infection, and respiratory function. Multidisciplinary coordination typically involves thoracic surgery or otolaryngology, anesthesiology, and respiratory therapy.
