ICD-10 Code K71.7 – Toxic liver disease with fibrosis and cirrhosis of liver (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K71.7 – Toxic liver disease with fibrosis and cirrhosis of liver
What it is
This code identifies liver damage caused by a toxic substance, with both fibrosis and cirrhosis documented. Use it when the record shows chronic toxic injury that has already led to scarring and cirrhotic change.
Clinical signs
Clinical features vary; refer to documentation. You may see signs of chronic liver disease, such as hepatomegaly, portal hypertension, jaundice, ascites, or other evidence of long-standing hepatic scarring.
When to use this code
Use K71.7 when the provider documents toxic liver disease and specifically states fibrosis and cirrhosis. The toxic cause may be medication, chemical exposure, or another hepatotoxic agent, but the record must link the injury to toxicity.
Assign this code only when cirrhosis is part of the diagnosis, not when liver injury is acute or fibrosis is absent. Check documentation if the cause, chronicity, or extent of liver damage is unclear.
Do not use for
Do not use this code for cirrhosis from alcohol, viral hepatitis, or other non-toxic causes. Do not use it for uncomplicated toxic hepatitis, fatty liver, or isolated fibrosis without cirrhosis.
Coding tip
Look for explicit provider wording that confirms both toxic etiology and cirrhosis before assigning K71.7.
