Amebic brain abscess

This code represents a severe, localized infection of the brain parenchyma caused by Entamoeba histolytica, an intestinal parasite. It signifies a serious extraintestinal manifestation of amebiasis, characterized by necrotic lesions within the brain tissue.

Apply this code when documentation clearly indicates a diagnosis of amebic brain abscess, typically confirmed by imaging (CT/MRI) showing a brain lesion in conjunction with serological tests or identification of E. histolytica. This diagnosis often follows a history of amebic dysentery or liver abscess.

• Ensure documentation specifies "brain" to differentiate from other amebic abscesses (e.g., liver, lung).
• Code any underlying or co-existing amebiasis (e.g., intestinal, hepatic) separately.
• Do not confuse with bacterial or fungal brain abscesses; the etiology must be explicitly amebic.
