Summary & Overview

CPT 42900: Closure of Wound or Injury of the Pharynx with Sutures

CPT code 42900 denotes the physician-performed closure of a wound or injury of the pharynx using sutures. This code captures a focused surgical repair of pharyngeal mucosa or deeper tissues and is relevant across hospital and ambulatory surgical settings. Nationally, accurate use of CPT code 42900 affects surgical billing, procedure tracking, and quality measurement for otolaryngology and emergency surgical care involving the oropharyngeal region.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines what clinicians and billing staff need to know about coding context, typical sites of service, and where this code appears in clinical workflows. Readers will find benchmarks for utilization and reimbursement patterns, summaries of relevant policy updates affecting surgical coding and coverage, and clinical context on indications and procedural considerations for pharyngeal wound closure.

The report is written for a national audience and focuses on standard coding application, payer coverage considerations, and operational implications for surgical services. Data not available in the input will be noted where applicable.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult who presents to the Emergency Department or outpatient ENT clinic after sustaining a penetrating or lacerating injury to the oropharynx or hypopharynx (for example, from a toothbrush, bone fragment, glass, or blunt trauma causing mucosal tears). The patient undergoes an initial clinical evaluation including airway assessment, hemodynamic stability check, and focused oropharyngeal examination. Imaging (plain radiographs, CT) is obtained as indicated to exclude retained foreign body, deep space infection, or vascular injury. Local anesthesia with topical spray and/or sedation is administered for comfort. The surgeon performs direct visualization of the pharyngeal wound with a laryngoscope or flexible endoscope, irrigates and debrides devitalized tissue, and closes mucosal and submucosal layers with interrupted sutures to restore integrity and reduce bleeding risk. Hemostasis is confirmed and, if needed, antibiotics and tetanus prophylaxis are provided. Post-procedure instructions include airway precautions, soft diet, analgesia, and follow-up for suture removal or wound re-evaluation.
