Summary & Overview
CPT 43279: Laparoscopic Esophagomyotomy, With or Without Fundoplasty
CPT code 43279 represents a laparoscopic esophagomyotomy, a minimally invasive foregut surgery that involves cutting the esophageal muscle and may include a fundoplasty to reduce gastroesophageal reflux. Nationally, this procedure is an important surgical option for patients with achalasia and other obstructive esophageal motility disorders; it influences surgical practice patterns, facility utilization, and payer coverage policies across hospital and ambulatory surgery settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for the procedure, common settings where the service is delivered, and the types of benchmarks and policy issues typically examined for surgical foregut procedures, including utilization metrics, site-of-service considerations, and coverage criteria. The publication also outlines common modifier usage and payer-specific administrative considerations when available.
This summary is intended for a national audience of policy analysts, billing managers, and clinical administrators who need concise clinical and billing context for CPT code 43279. Data not provided in the input are noted explicitly where relevant.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A typical patient is a 35–60-year-old adult presenting with progressive dysphagia to solids and liquids, regurgitation, chest pain, and weight loss. Diagnostic workup includes esophageal manometry confirming achalasia, upper endoscopy to exclude mechanical obstruction or malignancy, and barium esophagram demonstrating a bird’s-beak narrowing of the distal esophagus with esophageal dilation. After failure of conservative management (pneumatic dilation, botulinum toxin) or when durable symptomatic relief is desired, the patient is scheduled for a 43279 — laparoscopic Heller esophagomyotomy with or without partial fundoplication.
The typical clinical workflow: preoperative evaluation by the surgical team and anesthesia, informed consent addressing risks (esophageal perforation, GERD), perioperative antibiotics as indicated, general endotracheal anesthesia, laparoscopic transverse trocars placement, creation of a cardiomyotomy extending onto the gastric cardia, optional partial fundoplication (e.g., Dor or Toupet) to reduce postoperative reflux, intraoperative endoscopy or leak test as needed, postoperative recovery with a contrast swallow study when indicated, diet advancement from liquids to soft foods, and outpatient follow-up for symptom assessment and manometric or radiographic reassessment if symptoms persist or recur.
Typical site of service: Hospital outpatient surgery center or inpatient hospital operating room depending on patient comorbidities and local practice. Service type: Surgical — minimally invasive laparoscopic foregut procedure.
