Summary & Overview
CPT 43400: Esophageal Variceal Ligation to Prevent Bleeding
CPT code 43400 represents endoscopic ligation of dilated esophageal veins (variceal ligation), a procedure used to prevent or control potentially life-threatening upper gastrointestinal bleeding. Nationally, this code is important for acute gastroenterology and hepatology care, inpatient and outpatient endoscopy services, and hospital revenue for bleeding management. It also intersects with emergency care pathways when patients present with acute variceal hemorrhage.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing overview of the procedure, common places of service, and the typical service type. The publication outlines benchmarks and payment context where available, summarizes relevant policy and coverage considerations for major payers, and provides clinical context for when ligation is performed. When data elements were not provided in the input, the report notes that information is not available for those specific fields.
This national summary is intended to inform clinical administrators, coding and billing professionals, and policy analysts about the clinical role of CPT code 43400, the typical settings in which it is billed, and the payer landscape relevant to coverage and reimbursement discussions.
Billing Code Overview
CPT code 43400 describes the ligation of dilated (variceal) blood vessels in the esophagus to prevent rupture and bleeding. This procedure is an endoscopic intervention in which the provider ties off widened esophageal veins to control or prevent hemorrhage.
-
Service type: Endoscopic variceal ligation
-
Typical site of service: Ambulatory endoscopy suite or hospital-based endoscopy unit
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with portal hypertension due to cirrhosis who presents with signs of acute upper gastrointestinal bleeding (hematemesis or melena), or with known large esophageal varices identified on surveillance endoscopy requiring definitive endoscopic variceal ligation. The clinical workflow begins in the emergency department or endoscopy suite: initial hemodynamic stabilization (IV access, fluids/blood transfusion as needed, vasoactive medications such as octreotide), airway assessment and possible intubation for massive bleeding, and informed consent for endoscopic therapy. The patient is taken to the procedure room where an upper endoscope is advanced into the esophagus; the endoscopist identifies dilated varices and performs endoscopic variceal ligation (banding) by placing elastic bands around variceal columns to reduce the risk of rupture and control active bleeding. Post-procedure care includes monitoring for rebleeding, pain control, proton pump inhibitor therapy, and planning for repeat surveillance ligation sessions or referral for secondary prophylaxis (nonselective beta-blocker therapy or interventional radiology procedures if needed). Typical sites of service are the hospital operating room, endoscopy suite, or intensive care unit for unstable patients. Common patient scenarios include acute variceal hemorrhage, prophylactic treatment for high-risk varices, or bleeding refractory to medical therapy.
