ICD-10 Code K71 – Toxic liver disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71 – Toxic liver disease
What it is
K71 identifies liver injury caused by a toxic substance, including drugs, chemicals, or other harmful exposures. Use it when documentation states toxic hepatitis, toxic liver injury, or similar toxic liver disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include jaundice, abdominal pain, nausea, fatigue, and abnormal liver tests, but the record must support a toxic cause.
When to use this code
Use K71 when the clinician links liver disease or hepatitis to a toxic agent and does not assign a more specific code. It is appropriate when the note names a medication, chemical, or other toxin as the cause. Check documentation for the specific agent and whether additional external cause or poisoning codes are needed.
Do not use for
Do not use K71 for viral hepatitis, alcoholic liver disease, or unspecified liver dysfunction without toxic cause. If the record does not clearly identify toxicity, check documentation.
Coding tip
Always code the toxic agent and the liver condition together when documentation supports both.
