ICD-10 Code K71.1 – Toxic liver disease with hepatic necrosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.1 – Toxic liver disease with hepatic necrosis
What it is
K71.1 identifies liver injury caused by a toxic substance, with documented necrosis of liver tissue. Use it when the record shows toxic hepatitis or drug-related liver damage with hepatic cell death.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may describe acute liver injury, jaundice, abdominal discomfort, or laboratory evidence of hepatocellular damage with necrosis.
When to use this code
Use K71.1 when the provider links liver necrosis to a toxic agent, including medication, chemical, or other toxin exposure. It should be supported by documentation of toxic liver disease and hepatic necrosis, not just abnormal liver tests.
If the record names the causative substance, code that exposure as well when appropriate. Check documentation for whether the injury is acute, chronic, or due to an adverse drug effect.
Do not use for
Do not use this code for nonspecific liver dysfunction without necrosis, or for liver disease from causes other than a toxin. Check documentation if the chart does not clearly support hepatic necrosis.
Coding tip
Verify both the toxic cause and the presence of hepatic necrosis before assigning K71.1.
