Summary & Overview

CPT 43195: Rigid Endoscope Esophageal Balloon Dilation

CPT code 43195 represents rigid endoscope–assisted esophageal balloon dilation with balloon expansion to less than 30 mm. This endoscopic therapeutic procedure is used to widen focal esophageal strictures and is performed in ambulatory surgical centers or hospital outpatient departments. The code matters nationally because esophageal dilation is a common intervention across gastroenterology and thoracic surgery practices for symptom relief and to reduce complication risk from progressive dysphagia.

Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, common sites of service, and a summary of payer coverage considerations. The publication provides benchmarks and policy-relevant details that support coding accuracy, payer negotiation, and operational planning for facilities and providers. Data not available in the input is noted where specific payer policies, reimbursement rates, associated taxonomies, and ICD-10 diagnosis pairings would normally be summarized.

Billing Code Overview

CPT code 43195 describes a procedure in which a provider introduces a rigid endoscope through the mouth into the esophagus and advances a balloon through the scope. The balloon is then expanded to less than 30 mm to dilate a narrowed segment of the esophagus.

Service type: Endoscopic esophageal balloon dilation
Typical site of service: Ambulatory surgical center or hospital outpatient department; procedure is performed via the oral route into the esophagus.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting with progressive dysphagia to solids (and possibly liquids), intermittent regurgitation, and weight loss. Symptoms follow a prolonged history of gastroesophageal reflux disease or prior caustic injury, or occur after esophageal surgery or radiation. Initial evaluation includes history, physical exam, and diagnostic endoscopy with biopsy and/or contrast esophagram. When a focal benign or postsurgical esophageal stricture is identified that is resistant to medical therapy, the provider performs rigid esophagoscopy under general anesthesia, advances a rigid endoscope through the mouth into the esophagus, and introduces a balloon dilator through the scope. The balloon is inflated to less than 30 mm to perform controlled radial dilation to widen the narrowed segment. The procedure is commonly performed in an operating room or ambulatory surgery center with anesthesia monitoring; fluoroscopy may be used for guidance in select cases. Typical peri-procedural workflow includes preoperative consent and assessment, anesthesia induction, esophagoscopy with dilation, hemostasis if needed, post-anesthesia recovery, and discharge with diet and follow-up instructions. Documentation must include indication, findings, balloon size(s), number of inflations, maximum dilation diameter (confirming <30 mm), any immediate complications, and provider identity for accurate billing of 43195.

208000000X	General Surgery	General surgeons perform esophageal dilations, especially when associated with foregut disorders or surgical complications.
207RH0000X	Gastroenterology	Gastroenterologists perform esophageal dilations, though rigid dilations are more often by surgeons or in OR settings.
2086S0123X	Thoracic Surgery	Thoracic surgeons perform dilations in complex strictures related to esophageal disease or after thoracic procedures.
207L00000X	Oral and Maxillofacial Surgery	OMFS may be involved when access or oral structures require specialized management.

ICD-10 Code	Description	Clinical Relevance
`K22.2`	Diverticulum of esophagus	Structural abnormalities causing dysphagia and localized narrowing may require dilation.
`K22.0`	Achalasia of cardia	Motility disorder causing functional obstruction; dilation may be performed as therapeutic palliation.
