Summary & Overview
CPT 43420: Closure of Esophagostomy or Esophageal Fistula, Cervical Approach
CPT code 43420 denotes surgical closure of a previously placed esophagostomy or esophageal fistula through a cervical approach. This procedure indicates resolution of the underlying esophageal injury or disease and removal of the need for neck-based enteral feeding. Nationally, the code is relevant to surgical, otolaryngology, and thoracic practice patterns where airway and swallowing restoration is achieved following recovery.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, common modifiers associated with surgical billing, and how this service is categorized for procedural reporting. The publication also outlines expected care settings and the procedural intent—definitive closure of a healed esophagostomy/fistula via a neck incision.
This summary prepares clinicians, coding professionals, and payer policy analysts to understand where CPT code 43420 fits within surgical service lines and billing workflows. Data not available in the input will be identified explicitly in relevant sections of the full publication, while the main clinical and procedural elements of the code are detailed here for national application.
Billing Code Overview
CPT code 43420 describes closure of a previously placed esophagostomy or fistula via a cervical (neck) approach. The procedure is performed when the underlying wound or condition that necessitated the esophagostomy has healed and the patient no longer requires enteral feeding through the neck tube.
Service type: Surgical procedure — closure of esophagostomy/fistula
Typical site of service: Operating room or ambulatory surgical center, performed via a cervical/neck incision
Clinical & Coding Specifications
Clinical Context
A 62-year-old male who previously required an esophagostomy for long-term enteral feeding after traumatic cervical spine injury now presents for planned closure of the healed esophagostomy. The patient has demonstrated adequate oral intake and swallowing function on speech-language pathology evaluation and no evidence of local infection or fistula persistence. Preoperative evaluation by the surgeon confirms healed cervical soft tissues and absence of ongoing nutritional needs via tube. The procedure is scheduled in an outpatient surgical facility with general endotracheal anesthesia. Intraoperative steps typically include incision along the previous stoma tract in the neck, careful dissection to mobilize the esophageal and cutaneous edges, closure of the esophageal defect in layers, and layered closure of the cervical soft tissues and skin. Postoperative workflow includes short observation for airway compromise, pain control, swallowing assessment prior to oral intake, and discharge instructions with follow-up to monitor wound healing.
