ICD-10 Code I85.1 – Secondary esophageal varices (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I85.1 – Secondary esophageal varices
What it is
Secondary esophageal varices are enlarged, fragile veins in the esophagus caused by an underlying condition that increases portal venous pressure. This code identifies the varices as secondary, not primary or unspecified.
Clinical signs
They may be found on endoscopy and can be associated with portal hypertension or other documented underlying disease. Clinical features vary; refer to documentation.
When to use this code
Use I85.1 when the record clearly states secondary esophageal varices, including when the provider links them to an underlying cause. Code it from specialist documentation, discharge summaries, or procedure reports that name the condition. If the record only says esophageal varices without further detail, check documentation.
Do not use for
Do not use this code for primary or unspecified esophageal varices. Do not assign it when varices are mentioned without documentation of a secondary cause.
Coding tip
Confirm the word “secondary” or an explicit underlying cause in the chart before assigning I85.1.
