ICD-10 Code K71.3 – Toxic liver disease with chronic persistent hepatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.3 – Toxic liver disease with chronic persistent hepatitis
What it is
K71.3 identifies liver injury caused by a toxic substance, with a chronic persistent hepatitis pattern. Use it when documentation links ongoing hepatitis to a drug, chemical, or other toxin.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include persistent hepatic inflammation, abnormal liver tests, and a history of exposure to the suspected toxic agent.
When to use this code
Use K71.3 when the provider documents toxic liver disease and specifies chronic persistent hepatitis. It is appropriate when the record attributes the hepatitis to medication, toxin, or chemical exposure and does not describe a different toxic liver pattern.
Do not use for
Do not use this code for viral, autoimmune, or alcoholic hepatitis unless the record clearly states toxic causation. Check documentation if the liver injury type is unspecified or another toxic hepatitis subtype is named.
Coding tip
Confirm both the toxic cause and the chronic persistent hepatitis wording before assigning K71.3.
