Summary & Overview
CPT 43266: Endoscopic Esophageal Stent Placement
CPT code 43266 represents endoscopic placement of an esophageal stent, including endoscopic examination of the esophagus, stomach, and duodenum with stent deployment and optional guidewire-assisted dilation. The procedure is an important therapeutic option for patients with esophageal strictures, malignant obstruction, or other causes of luminal narrowing that impair swallowing. Nationally, this code captures resource use for interventional upper gastrointestinal endoscopy and informs facility and professional billing across outpatient and ambulatory surgical settings.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides readers with clinical context for when stent placement is coded, an overview of typical sites of service, and what to expect in billing practice. It also summarizes common modifier usage where available and highlights areas where coding guidance or payer policy may affect reimbursement and claim adjudication.
Readers will learn the clinical indication and service scope tied to CPT code 43266, the payer mix typically involved in national billing, and the types of benchmarks and policy considerations that commonly influence coverage and payment. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 43266 describes an upper endoscopic procedure in which a thin, flexible, lighted endoscope is inserted through the mouth to examine the esophagus, stomach, and duodenum. During the procedure a stent is inserted through the endoscope into a narrowed segment of the esophagus; a guidewire may be placed before and after stent deployment and dilators may be passed over the guidewire to widen the esophagus as needed.

Service type: Endoscopic esophageal stent placement with possible guidewire-assisted dilation
-
Typical site of service: Hospital outpatient department or ambulatory endoscopy center (procedural suite for upper GI endoscopy)
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with progressive dysphagia and unintentional weight loss is referred to gastroenterology after an upper endoscopy shows a malignant-appearing stricture of the mid‑esophagus. The patient arrives to the ambulatory endoscopy suite fasting, has pre-procedure consent and pre-anesthesia screening, and receives monitored anesthesia care. The gastroenterologist performs an upper endoscopy (esophagogastroduodenoscopy) using a thin, flexible, lighted endoscope to inspect the esophagus, stomach, and duodenum. After visualizing the obstructing lesion and confirming a tight malignant stricture, the endoscopist passes a guidewire across the narrowed segment and may perform graded dilation with dilators or balloon catheters. Through the working channel of the endoscope, the physician deploys an esophageal stent to restore luminal patency. The procedure may include fluoroscopic confirmation of stent position, endoscopic biopsy, lavage, or aspiration management as needed. Post-procedure, the patient is observed in recovery, given diet and discharge instructions, and scheduled for follow-up and potential stent surveillance or exchange.
