ICD-10 Code K72.0 – Acute and subacute hepatic failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K72.0 – Acute and subacute hepatic failure
What it is
K72.0 identifies acute or subacute hepatic failure, a rapid loss of liver function that develops over days to weeks. Use it when documentation shows new, severe liver dysfunction rather than chronic cirrhosis.
Clinical signs
Typical findings include jaundice, encephalopathy, coagulopathy, and marked liver dysfunction. Clinical features vary; refer to documentation for the specific presentation and severity.
When to use this code
Use K72.0 when the record clearly states acute hepatic failure or subacute hepatic failure. It also fits cases described as fulminant liver failure if the provider documents an acute or subacute process. Check documentation when liver failure is mentioned without timing.
Do not use for
Do not use this code for chronic liver failure, cirrhosis, or unspecified hepatic failure unless the provider documents an acute or subacute episode. Do not guess the stage from abnormal liver tests alone.
Coding tip
Look for the provider’s timing language; acute and subacute liver failure are coded only when the record supports a rapid onset.
