A06.4

What This Code Means

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.

Coding Tips

• •Verify documentation confirms amebic etiology (caused by Entamoeba histolytica) rather than other causes of liver abscess, as this distinction is critical for accurate coding
• •Ensure the abscess is specifically documented as hepatic/liver involvement; if amebic infection affects other sites (intestine, lung, etc.), those would require separate codes
