Chronic intestinal amebiasis

This code signifies a persistent parasitic infection of the intestines caused by Entamoeba histolytica, characterized by long-term symptoms such as recurrent diarrhea, abdominal pain, and weight loss. Unlike acute amebiasis, chronic forms often involve less severe but ongoing inflammation and ulceration of the colon.

Assign this code when documentation clearly indicates a diagnosis of chronic intestinal amebiasis, often supported by stool microscopy identifying E. histolytica cysts or trophozoites, or serological tests. It is appropriate for patients presenting with a history of recurrent gastrointestinal symptoms consistent with amebiasis that have persisted over an extended period.

• Differentiate from acute intestinal amebiasis (A06.0) based on the chronicity of symptoms and diagnostic findings.
• Ensure documentation specifies "chronic" to support the use of this subcategory.
• Code any associated complications, such as amebic liver abscess (A06.4) or other extraintestinal manifestations, in addition to this code.
