ICD-10 Code B19.0 – Unspecified viral hepatitis with hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B19.0 – Unspecified viral hepatitis with hepatic coma
What it is
This code identifies viral hepatitis that is not otherwise specified and is complicated by hepatic coma. Use it when the record confirms viral hepatitis, but the exact virus is not documented.
Clinical signs
Clinical features vary; refer to documentation. Hepatic coma implies severe liver dysfunction with altered mental status or unresponsiveness in the setting of hepatitis.
When to use this code
Use B19.0 when the provider documents unspecified viral hepatitis and clearly links it to hepatic coma. It fits cases where the viral type is not stated, but the coma is attributed to liver failure from hepatitis.
If the record names a specific viral hepatitis type, code that specific diagnosis instead. Check documentation when coma is present but the cause is unclear.
Do not use for
Do not use this code for viral hepatitis without hepatic coma. Also avoid it when a more specific hepatitis code is documented or when coma is due to another cause.
Coding tip
Code the hepatitis type first if it is documented; otherwise, use B19.0 only when the record supports unspecified viral hepatitis with hepatic coma.
