ICD-10 Code K75.3 – Granulomatous hepatitis, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K75.3 – Granulomatous hepatitis, not elsewhere classified
What it is
K75.3 identifies granulomatous hepatitis, a liver condition marked by granuloma formation in hepatic tissue. Use it when the record specifically documents this diagnosis and no more specific cause is named.
Clinical signs
Clinical features vary; refer to documentation. Patients may have abnormal liver findings or imaging, and diagnosis is often confirmed by biopsy showing granulomas in the liver.
When to use this code
Use K75.3 when the clinician documents granulomatous hepatitis without naming a more specific underlying disease. It may also apply when the condition is listed as idiopathic or otherwise not classified. If the note identifies an infectious, autoimmune, or drug-related cause, code the documented cause instead.
Do not use for
Do not use this code for general hepatitis without granulomas, or for liver disease with a clearly documented alternate etiology. Check documentation if the record only mentions granulomas elsewhere in the body.
Coding tip
Confirm that the provider links granulomas to the liver and does not specify a more exact diagnosis before assigning K75.3.
