ICD-10 Code B17.2 – Acute hepatitis E (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B17.2 – Acute hepatitis E
What it is
B17.2 identifies an acute hepatitis E infection, a short-term viral inflammation of the liver caused by the hepatitis E virus. Use it when the record documents acute hepatitis E or HEV infection.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include jaundice, fatigue, nausea, abdominal discomfort, and elevated liver enzymes consistent with acute viral hepatitis.
When to use this code
Use B17.2 when the provider clearly documents acute hepatitis E, hepatitis E virus infection, or acute HEV hepatitis. It fits confirmed or clinically diagnosed acute cases in outpatient, inpatient, or emergency settings. If the note only says “hepatitis” without type, check documentation.
Do not use for
Do not use this code for chronic hepatitis, other viral hepatitis types, or nonspecific liver inflammation without hepatitis E confirmation. Check documentation if the record does not distinguish acute from other forms.
Coding tip
Code B17.2 only when hepatitis E is specifically identified; otherwise, query for the viral type and acuity.
