ICD-10 Code K71.5 – Toxic liver disease with chronic active hepatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.5 – Toxic liver disease with chronic active hepatitis
What it is
K71.5 identifies liver injury caused by a toxic substance, with a chronic active hepatitis pattern. Use it when documentation links the hepatitis to a drug, chemical, or other toxin.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe persistent hepatitis, ongoing liver inflammation, and evidence that the injury is toxin-related rather than viral or autoimmune.
When to use this code
Use this code when the provider documents toxic liver disease with chronic active hepatitis. It may appear in assessments, discharge diagnoses, or pathology/imaging reports that clearly attribute chronic active hepatitis to a toxic exposure. If the cause is not stated, check documentation.
Do not use for
Do not use it for unspecified hepatitis, acute toxic hepatitis, or liver disease without a documented chronic active hepatitis pattern. Do not assign it when the record does not link the condition to a toxic cause.
Coding tip
Confirm both elements in the chart: toxic liver disease and chronic active hepatitis.
