ICD-10 Code K75.0 – Abscess of liver (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K75.0 – Abscess of liver
What it is
K75.0 identifies a localized collection of pus within the liver. It reflects an infectious process that may be bacterial, amebic, or otherwise documented as a liver abscess.
Clinical signs
Clinical features vary; refer to documentation. Common findings include right upper quadrant pain, fever, malaise, and an enlarged or tender liver. Imaging is often used to confirm the abscess.
When to use this code
Use K75.0 when the provider documents a liver abscess, hepatic abscess, or abscess of the liver. Code it when the record supports a true abscess rather than nonspecific liver inflammation or another hepatic lesion. If the type or cause is stated, capture it only if documented and supported by the record.
Do not use for
Do not use this code for hepatitis, liver cysts, or other noninfectious liver masses. If the chart only says “liver lesion” or the diagnosis is unclear, check documentation.
Coding tip
Confirm the provider’s final diagnosis and any stated etiology before assigning K75.0.
