Summary & Overview
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.

Service type: Endoscopic esophageal dilation with guidewire-assisted dilators

Typical site of service: Ambulatory endoscopy suite or hospital-based endoscopy unit
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.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician professional component separate from facility (rare for endoscopy). |
52 | Reduced services | Use when the procedure was partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Use when the procedure was started but terminated due to extenuating circumstances (e.g., adverse reaction, poor visualization). |
59 | Distinct procedural service | Use to indicate a separate, distinct procedure performed on the same day when not ordinarily bundled. |
62 | Two surgeons | Use when two surgeons of different specialties are required and both actively participate. |
66 | Surgical team | Use when a surgical team is necessary for the procedure. |
78 | Return to operating room for a related procedure during postoperative period | Use if a complication requires return to OR for related management. |
79 | Unrelated procedure or service by the same physician during postoperative period | Use when an unrelated procedure is performed during the global period. |
73 | Discontinued outpatient hospital/ASC procedure prior to anesthesia | Use when procedure is discontinued prior to anesthesia administration. |
74 | Discontinued outpatient hospital/ASC procedure after anesthesia | Use when discontinued after anesthesia but before completion. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207RC0000X | Gastroenterology | Most common specialty performing therapeutic EGD with esophageal dilation. |
2080S0121X | Thoracic Surgery | May perform dilation when related to complex esophageal surgery or strictures. |
208000000X | General Surgery | General surgeons with endoscopic privileges may perform dilation in some settings. |
363LA2200X | Hospitalist/Internal Medicine (Interventional) | In limited settings where procedural internal medicine performs endoscopy; less common. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
K22.1 | Stricture and stenosis of esophagus | Direct indication for esophageal dilation to relieve obstructive symptoms. |
K20.9 | Esophagitis, unspecified | Inflammatory strictures from chronic esophagitis may require dilation. |
K21.9 | Gastroesophageal reflux disease without esophagitis | Chronic GERD can lead to peptic strictures treated with dilation. |
K25.9 | Gastric ulcer, unspecified as acute or chronic, without hemorrhage or perforation | Ulcer-related scarring near the GE junction may contribute to dysphagia; dilation may be used cautiously. |
K22.8 | Other specified diseases of esophagus | Miscellaneous esophageal conditions causing luminal narrowing amenable to dilation. |
R13.10 | Dysphagia, unspecified | Symptom commonly prompting diagnostic endoscopy and therapeutic dilation. |
C15.9 | Malignant neoplasm of esophagus, unspecified | Malignant strictures may be dilated for palliation; document risks and alternatives. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
43235 | Esophagogastroduodenoscopy, diagnostic, flexible, transoral; with biopsy, single or multiple | Often performed before or during the same encounter to obtain biopsies for stricture etiology (e.g., eosinophilic esophagitis, malignancy). |
43239 | Esophagogastroduodenoscopy, flexible, transoral; with foreign body removal, without anesthesia by intrathoracic approach | May be performed when a retained food bolus or foreign body is present and requires removal prior to or during dilation. |
43249 | Esophagogastroduodenoscopy with insertion of guidewire, dilation; with direct visualization, balloon dilation (separate code for balloon technique) | Represents an alternative dilation technique (balloon) and is billed when balloon dilation is used rather than dilators over a guidewire. |
43255 | Esophagoscopy, rigid or flexible; with dilation, without guidewire (simple bougie dilation) | Billed when dilation is performed without guidewire assistance; differentiates technique from 43248. |
99152 | Moderate sedation services provided by the same physician performing the diagnostic or therapeutic service (initial 15–30 minutes) | Used when the endoscopist also provides moderate sedation services during the procedure; document time and sedation details. |
