ICD-10 Code B17.11 – Acute hepatitis C with hepatic coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B17.11 – Acute hepatitis C with hepatic coma
What it is
B17.11 identifies an acute hepatitis C infection complicated by hepatic coma. Use it when documentation shows sudden hepatitis C with loss of consciousness from severe liver dysfunction.
Clinical signs
Typical findings include acute hepatitis symptoms plus altered mental status consistent with hepatic encephalopathy or coma. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute hepatitis C and specifically links it to hepatic coma. It applies when the coma is part of the acute liver illness, not a separate neurologic diagnosis. Check documentation if the record only notes hepatitis C without coma.
Do not use for
Do not use it for chronic hepatitis C, resolved infection, or hepatitis C without hepatic coma. Do not assign it when coma is documented from another cause.
Coding tip
Confirm that the record clearly links the coma to acute hepatitis C before assigning B17.11.
