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.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Normal or uncomplicated procedure | Use for a standard EGD when no unusual circumstances exist. |
22 | Increased procedural services | Use when the EGD requires substantially greater effort or time due to complexity (extensive lysis of adhesions, prolonged ablation session). |
23 | Unusual anesthesia | Use if general anesthesia is medically necessary for the EGD rather than usual sedation. |
52 | Reduced services | Use when the EGD is started but discontinued for clinical reasons and reduced in scope. |
53 | Discontinued procedure | Use when the EGD is aborted and terminated prior to completion for patient safety. |
59 | Distinct procedural service | Use to indicate a separate, distinct EGD-related service when multiple procedures are reported on the same day and not normally bundled. |
62 | Two surgeons | Use when two physicians of the same specialty perform the EGD together and both meet documentation requirements. |
76 | Repeat procedure by same physician | Data not provided in input. |
78 | Return to OR for related procedure during postoperative period | Use if patient requires an unplanned return to an operative setting for a complication of the EGD. |
79 | Unrelated procedure during postoperative period | Use when an unrelated procedure is performed during the global period. |
GC | Services performed by resident under teaching physician | Use when a resident performs the EGD with appropriate teaching physician involvement. |
QK | Medical direction of 2-4 anesthesia professionals | Use when the reporting physician directs multiple CRNAs for anesthesia during the EGD. |
QX | CRNA service with medical direction | Use when a CRNA furnishes anesthesia under physician direction during the procedure. |
QY | Medical direction of one CRNA by anesthesiologist | Use for physician-directed anesthesia for the EGD. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use when an advanced practice provider performs or assists in the EGD per payer rules. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207RH0000X | Gastroenterology | Core specialty performing diagnostic and therapeutic EGD. |
| 207RC0000X | General Surgery | General surgeons perform operative endoscopy, dilation, or lesion ablation in some settings. |
| 207RN0300X | Pulmonology | Mentioned rarely for upper airway/endoscopic overlap; primarily included when multidisciplinary airway management is needed. |
| 363LA2200X | Anesthesiology | Provides monitored anesthesia care or general anesthesia for complex EGDs when required. |
| 363LM0800X | Nurse Anesthetist | CRNA supervision and billing roles for procedural sedation/anesthesia. |
