A06.4 ICD-10-CM Code: Amebic liver abscess

A06.4 is the ICD-10-CM diagnosis code for amebic liver abscess. A liver abscess (a collection of pus in the liver) caused by a parasitic infection from Entamoeba histolytica, a microscopic organism typically acquired through contaminated food or water. This is a serious complication of amebic infection that requires medical treatment. A06.4 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering intestinal infectious diseases (a00-a09).

A06.4 has no mapping under the CMS-HCC V28 or V24 community payment models. A06.4 also appears in the HHS-HCC commercial risk model (HCC 035_1 (HHS-HCC 035_1 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

Verify documentation confirms amebic etiology (caused by Entamoeba histolytica) rather than other causes of liver abscess, as this distinction is critical for accurate coding.
