ICD-10 Code B19.11 – Unspecified viral hepatitis B with hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B19.11 – Unspecified viral hepatitis B with hepatic coma
What it is
This code identifies an unspecified viral hepatitis B infection complicated by hepatic coma. Use it when the record documents hepatitis B with coma from liver failure, but does not specify a more detailed type.
Clinical signs
Clinical features vary; refer to documentation. Hepatic coma usually reflects severe liver dysfunction with altered mental status, confusion, or reduced responsiveness in the setting of hepatitis B.
When to use this code
Use this code when the provider documents viral hepatitis B and hepatic coma, but the chart does not identify a more specific hepatitis B category. It is appropriate for inpatient or emergency records where coma is clearly linked to the hepatitis B illness. Check documentation if the cause of coma is uncertain or another liver condition is documented instead.
Do not use for
Do not use this code for hepatitis B without coma, or for coma from causes unrelated to viral hepatitis B. If the record specifies a different hepatitis B form, code that more specific diagnosis instead.
Coding tip
Verify that the provider explicitly connects hepatic coma to hepatitis B before assigning B19.11.
