ICD-10 Code K71.11 – Toxic liver disease with hepatic necrosis, with coma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.11 – Toxic liver disease with hepatic necrosis, with coma
What it is
K71.11 identifies toxic liver disease caused by a harmful substance, with liver cell death and associated coma. Use it when documentation clearly links the liver injury to a toxin and notes coma.
Clinical signs
Clinical features may include acute liver dysfunction, encephalopathy, and decreased consciousness progressing to coma. Clinical features vary; refer to documentation for the specific toxin, severity, and whether hepatic necrosis is stated.
When to use this code
Use this code when the record documents toxic liver injury with hepatic necrosis and coma, not just altered mental status. You should also confirm that the cause is toxic or drug-related and that the provider attributes the coma to the liver condition.
Do not use for
Do not use K71.11 if hepatic necrosis or coma is not documented, or if the liver disease is not toxic in origin. Check documentation when the chart only mentions hepatitis, liver failure, or encephalopathy without clear necrosis.
Coding tip
Verify the toxic agent and the linkage between coma and liver disease before assigning K71.11.
