ICD-10 Code K72.9 – Hepatic failure, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K72.9 – Hepatic failure, unspecified
What it is
K72.9 identifies hepatic failure when the record does not specify the cause or whether it is acute, chronic, or acute-on-chronic. Use it for documented liver failure without further detail.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include jaundice, confusion, coagulopathy, and signs of impaired liver function, but the chart must support hepatic failure rather than simple liver disease.
When to use this code
Use K72.9 when the provider documents hepatic failure, liver failure, or fulminant liver failure without additional specification. It also fits when the note confirms failure but does not state the underlying cause or acuity. If the record gives more detail, code that more specific option instead.
Do not use for
Do not use this code for uncomplicated hepatitis, cirrhosis, or abnormal liver tests alone. Check documentation if the provider describes acute, chronic, or toxic liver failure, because a more specific code may apply.
Coding tip
Query for acuity and cause whenever the note only says “liver failure,” because specificity can change the code selection.
