Summary & Overview
CPT 43270: Esophagogastroduodenoscopy with Dilation and Lesion Ablation
CPT code 43270 represents an esophagogastroduodenoscopy (EGD) that includes passage of guidewires, dilation of strictures when necessary, and ablation of one or more lesions. This combination diagnostic and therapeutic upper gastrointestinal procedure is widely used in gastroenterology for evaluation and immediate treatment of mucosal lesions, strictures, and bleeding sources. Nationally, CPT code 43270 is relevant for hospital outpatient departments, ambulatory surgical centers, and specialized endoscopy suites and impacts coding, billing, and utilization protocols across public and private payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context of the procedure, payer coverage considerations, common modifiers in use, and linked billing concepts. The publication provides benchmarks and policy context where available, clarifies sites of service and service type, and outlines the clinical actions represented by the code—visualization, guidewire placement, dilation, and lesion ablation. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 43270 describes an esophagogastroduodenoscopy (EGD) performed with passage of a flexible endoscope through the mouth to visualize the esophagus, stomach, and duodenum. During the procedure, the provider may pass guidewires and dilate narrowed areas as needed and ablate (destroy) one or more lesions.
-
Service type: Diagnostic and therapeutic upper gastrointestinal endoscopy with lesion ablation and possible dilation
-
Typical site of service: Hospital outpatient department or ambulatory surgical center; may also be performed in endoscopy suites within hospital settings
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with progressive dysphagia and weight loss is referred to gastroenterology for diagnostic and therapeutic evaluation. The clinician schedules an esophagogastroduodenoscopy (EGD) with possible dilation and endoscopic ablation of mucosal lesions. On the day of service the patient arrives to an outpatient endoscopy center, is assessed by nursing, and consents for the procedure. Procedural sedation (monitored anesthesia care or conscious sedation) is provided per facility policy. A flexible upper endoscope is advanced through the mouth to inspect the esophagus, stomach, and duodenum. Narrowed segments are traversed with guidewires and dilated if necessary. Visualized lesions (for example Barrett mucosa with dysplasia or isolated nodular lesions) are treated with endoscopic ablation (e.g., radiofrequency ablation or cryoablation) or focal destruction as indicated. Biopsies or specimen retrieval may be performed during the same session. The patient is recovered in the post-anesthesia area and discharged with procedure instructions and follow-up arranged based on findings and pathology results.
