ICD-10 Code A06.4 – Amebic liver abscess (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A06.4 – Amebic liver abscess
What it is
A06.4 identifies a liver abscess caused by Entamoeba histolytica infection. Use it when the record documents an amebic cause rather than a pyogenic or unspecified liver abscess.
Clinical signs
Patients may have right upper quadrant pain, fever, hepatomegaly, or tenderness. Clinical features vary; refer to documentation, and confirm the amebic etiology when recorded.
When to use this code
Use this code when the provider documents amebic liver abscess, hepatic amebiasis, or a liver abscess due to Entamoeba histolytica. Apply it for confirmed infection involving the liver, even if intestinal symptoms are not emphasized. Check documentation if the cause is unclear.
Do not use for
Do not use A06.4 for pyogenic liver abscess, nonspecific hepatic abscess, or liver lesions without infectious documentation. If the note does not clearly identify an amebic cause, use the documented diagnosis instead.
Coding tip
Code the amebic source only when the provider explicitly links the abscess to Entamoeba histolytica.
