Summary & Overview

CPT 43497: Endoscopic Myotomy of Lower Esophagus, Therapeutic

CPT code 43497 covers an endoscopic therapeutic myotomy performed via the mouth to cut muscle tissue in the lower esophagus and relax the lower esophageal sphincter. The procedure is clinically significant for treating disorders of esophageal outflow and can reduce symptoms such as dysphagia and chest pain. Nationally, this code reflects an advanced endoscopic intervention that intersects gastroenterology and surgical services and influences facility resource use and payer coverage decisions.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common sites of service, and the procedural nature of the code. The publication also provides benchmarks and policy-relevant content where available, including coding guidance, utilization trends, and payer coverage patterns. Where specific input data were not provided, the report notes data gaps and focuses on authoritative description and operational implications for billing and service delivery. The content is written for a national audience of clinicians, billing professionals, and policy analysts seeking clear information about the role and implications of CPT code 43497 in practice.

Billing Code Overview

CPT code 43497 describes an endoscopic procedure in which a provider inserts an endoscope through the mouth to cut muscle tissue in the lower esophagus, thereby relaxing the esophageal musculature. This procedure is therapeutic and targets the lower esophageal sphincter to relieve obstructive symptoms related to impaired relaxation.

Service type: Endoscopic therapeutic myotomy of the lower esophagus
Typical site of service: Hospital operating room or ambulatory surgical center

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting with progressive dysphagia to solids and liquids, regurgitation of undigested food, chest pain, and weight loss after conservative therapies. Diagnostic workup includes esophagogastroduodenoscopy (EGD) to exclude mechanical obstruction, high-resolution esophageal manometry confirming achalasia or a related esophageal motility disorder, and barium esophagram demonstrating a narrowed gastroesophageal junction with esophageal dilation. The treatment plan involves a minimally invasive endoscopic myotomy performed under general anesthesia using an endoscope inserted through the mouth to create a submucosal tunnel and selectively cut the lower esophageal circular muscle fibers to relieve outflow obstruction. Typical workflow: preoperative evaluation and consent, anesthesia induction, endoscopic creation of submucosal tunnel, selective myotomy of the lower esophageal sphincter and proximal stomach as indicated, assessment for mucosal integrity, closure of the mucosal entry (usually with endoscopic clips), postoperative observation for complications (bleeding, pneumothorax, mediastinitis, or perforation), swallow study or contrast study as indicated prior to oral intake, and short-term outpatient follow-up to assess symptom improvement and need for further interventions. Usual site of service is an ambulatory surgery center or hospital operating room with endoscopy capability and anesthesiology support.
