ICD-10 Code I86.4 – Gastric varices (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I86.4 – Gastric varices
What it is
Gastric varices are enlarged, twisted veins in the stomach. This code identifies the diagnosis of gastric varices, usually related to portal venous pressure changes.
Clinical signs
Clinical features vary; refer to documentation. They may be found on endoscopy or imaging and can be associated with upper gastrointestinal bleeding, anemia, or signs of portal hypertension.
When to use this code
Use I86.4 when the provider documents gastric varices as an active diagnosis, whether found incidentally or during evaluation of bleeding. Code it when the record specifically identifies varices in the stomach and not just esophageal varices or general portal hypertension.
Do not use for
Do not use this code for esophageal varices, gastric ulcer bleeding, or nonspecific upper GI hemorrhage without documented gastric varices. Check documentation if the site of varices is unclear.
Coding tip
Verify the anatomic site in the report; stomach varices and esophageal varices are coded separately.
