Summary & Overview
CPT 43425: Closure of Esophagostomy or Esophageal Fistula
Headline: CPT code 43425 — Surgical closure of esophagostomy or esophageal fistula. Lead: CPT code 43425 denotes the definitive surgical closure of a previously placed esophagostomy or fistula via a transthoracic or midline abdominal incision when the underlying condition has healed and tube feeding is no longer required. This code captures an important transitional procedure that restores alimentary continuity and closes an external esophageal access site.
Why it matters: Nationally, procedures that reverse temporary enteral access have implications for surgical quality, postoperative care pathways, and facility resource use. Accurate use of CPT code 43425 affects clinical documentation, claims processing, and longitudinal patient records for those recovering from esophageal injury or surgical interventions.
Payers covered: This summary addresses common national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication provides clinical context for when CPT code 43425 is appropriate, the typical surgical setting and service type, and payer coverage considerations. It includes benchmarks and policy-relevant notes where available, coding guidance for claim preparation, and links to related procedural codes and postoperative care considerations. Data not available in the input will be identified as such, and the piece focuses on national practice and payer patterns rather than state-specific rules.
Billing Code Overview
CPT code 43425 describes the surgical closure of a previously placed esophagostomy or fistula through a transthoracic or midline abdominal incision. The procedure is performed when the underlying wound or injury that required the esophagostomy has healed and the patient no longer requires enteral feeding via the external esophagostomy tube.

Service type: Surgical procedure to close an esophagostomy or esophageal fistula
-
Typical site of service: Inpatient or outpatient surgical setting, performed via transthoracic or midline abdominal incision
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who previously underwent placement of an esophagostomy tube for temporary enteral nutrition following head and neck cancer resection, severe oropharyngeal trauma, or prolonged aspiration risk. After interval healing of the primary disease or recovery of swallowing function, the patient presents for elective removal and closure of the mature esophagostomy or fistula. Preoperative evaluation includes confirmation of healed tract (clinical exam, imaging if indicated), review of nutrition status, anesthesia assessment, and informed consent. The procedure is usually performed in an operating room under general anesthesia or monitored anesthesia care with a midline abdominal or transthoracic incision to excise the tract and close the fistulous opening to the esophagus. Intraoperative steps include identification of the tract, mobilization, debridement of scar tissue, layered closure of the esophageal and soft-tissue defects, and layered skin closure. Postoperative workflow includes short-term inpatient observation for airway and swallowing function, pain control, wound care, return-to-oral-intake assessment, and documentation of tube removal and definitive closure in operative and discharge notes. Typical sites of service are the hospital main OR or ambulatory surgical center when patient comorbidities permit outpatient management. Typical service type: open surgical closure (definitive wound/fistula closure) of a previously placed esophagostomy.
