Summary & Overview
CPT 43226: Esophagoscopy with Dilation Using Flexible Endoscope
CPT code 43226 denotes a flexible esophagoscopy with dilation using dilators passed over a guidewire to treat esophageal strictures. This endoscopic therapeutic procedure is widely performed to relieve dysphagia and restore luminal patency, making it an important code for gastroenterology, otolaryngology, and surgical practices. Nationally, accurate coding of 43226 matters for clinical documentation, appropriate site-of-service reporting, and alignment with payer coverage policies.
Key payers considered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context and typical sites of service, plus a summary of what to expect in payer coverage and billing practice: common utilization settings, potential documentation elements that support medical necessity, and related coding considerations. Data specific to benchmarks, modifiers, taxonomies, ICD-10 links, and payer-specific reimbursement details are noted as available or missing where applicable.
This publication provides a national-level reference on the clinical purpose and billing context for 43226, helping billing staff, clinicians, and policy analysts understand the code’s role in esophageal therapeutic care and administrative workflows.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with progressive dysphagia to solids presents after an upper endoscopy that identified a short-segment esophageal stricture secondary to chronic gastroesophageal reflux disease. The patient is scheduled for an outpatient flexible esophagoscopy with dilation. The clinical workflow includes pre-procedure assessment (consent, NPO status, medication reconciliation, anesthesia evaluation), administration of moderate sedation or monitored anesthesia care, passage of a flexible endoscope through the oral cavity to the esophagus for direct visualization, placement of a guidewire across the narrowing, and sequential dilatation using bougie or balloon dilators to restore luminal diameter. Post-procedure monitoring in the recovery area includes assessment for perforation, bleeding, and adequate return of airway protective reflexes before discharge with instructions and follow-up to monitor symptom response and potential need for repeat dilation or further evaluation.
