Amebic lung abscess

This code represents a pulmonary infection caused by the parasite Entamoeba histolytica, leading to the formation of an abscess within the lung tissue. It typically occurs as a complication of amebic dysentery or hepatic amebiasis, where the parasites spread hematogenously to the lungs.

Use this code when documentation clearly indicates a lung abscess specifically attributed to amebic infection. Supporting documentation should include positive serology for Entamoeba histolytica, identification of trophozoites in sputum or lung aspirate, or a clinical picture consistent with amebic lung involvement following gastrointestinal or liver amebiasis.

• Always look for documentation of the causative organism (Entamoeba histolytica) to differentiate from bacterial or fungal lung abscesses.
• Consider sequencing this code after codes for amebic dysentery (A06.0-A06.3) or amebic liver abscess (A06.4) if the lung abscess is a direct complication.
• Do not confuse with non-amebic lung abscesses (J85.2) or other parasitic lung diseases.
