CPT 43248: Endoscopic Esophageal Dilation with Guidewire-Assisted Dilators
CPT code 43248 represents endoscopic esophageal dilation performed via a flexible endoscope inserted orally, with a guidewire passed through the scope and dilators advanced over the wire. This procedure addresses esophageal strictures and obstructive lesions and is an important, commonly billed therapeutic endoscopic service across outpatient and hospital settings. Nationally, accurate coding for 43248 affects quality measurement, utilization tracking, and payment for digestive disease care.
Key payers reviewed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for esophageal dilation, typical sites of service, and the relevance of the code to procedural workflows. The publication presents benchmarks for utilization and payment where available, highlights relevant coding considerations, and summarizes recent policy or coverage developments that influence how payers handle endoscopic dilation claims.
The content is intended to inform coding professionals, practice managers, and policy analysts about the clinical and billing contours of 43248, the settings in which it is performed, and the payer landscape that governs coverage and reimbursement. Data not available in the input will be noted explicitly in relevant sections of the full publication.
Billing Code Overview
CPT code 43248 describes upper gastrointestinal endoscopy with esophageal dilation using a guidewire and graduated dilators passed through a flexible endoscope inserted orally. The procedure involves advancing a flexible endoscope through the mouth into the esophagus, stomach, and duodenum and then passing a guidewire through the scope over which esophageal dilators are introduced.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with progressive dysphagia and known esophageal stricture presents for therapeutic endoscopy. The patient reports solid-food dysphagia over several months with intermittent regurgitation and weight loss. Pre-procedure evaluation includes history, focused physical exam, informed consent, and review of prior imaging (barium swallow or prior endoscopy) and pathology if available. The procedure is performed in an endoscopy suite or ambulatory surgery center under moderate sedation or monitored anesthesia care. A flexible upper endoscope (esophagogastroduodenoscope) is passed orally into the esophagus and stomach; a guidewire is advanced across the stricture under direct visualization, and progressively larger dilators (bougie or balloon dilators passed over the guidewire) are used to restore luminal diameter. Post-procedure monitoring includes recovery from sedation, assessment for bleeding or perforation, diet advancement instructions, and documentation of dilation size, number of dilators, guidewire use, and any immediate complications. Typical providers include gastroenterologists or thoracic surgeons with endoscopic privileges. Billing applies to therapeutic endoscopic esophageal dilation using a guidewire and dilators as described by 43248.
