ICD-10 Code K76.0 – Fatty (change of) liver, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K76.0 – Fatty (change of) liver, not elsewhere classified
What it is
K76.0 identifies fatty change in the liver, also called hepatic steatosis, when it is not classified elsewhere. It means excess fat has accumulated in liver cells, based on clinical or imaging documentation.
Clinical signs
Clinical features vary; refer to documentation. Many patients have no symptoms, while others may have right upper quadrant discomfort, mild liver enlargement, or incidental imaging findings consistent with fatty liver.
When to use this code
Use K76.0 when the record documents fatty liver, hepatic steatosis, or fatty change of the liver without a more specific liver diagnosis. Assign it for incidental imaging findings or provider-documented nonalcoholic fatty liver when no alternate code is specified. Do not infer the cause.
Do not use for
Do not use this code for alcoholic liver disease or other specified liver disorders. If documentation names a different etiology or condition, check documentation and code the more specific diagnosis instead.
Coding tip
Confirm the provider’s exact wording; “fatty liver” alone usually supports K76.0 only when no other liver condition is documented.
