Amebic skin ulceration

This code describes cutaneous manifestations of amebiasis, specifically ulcerations of the skin caused by Entamoeba histolytica. These lesions typically present as painful, progressive ulcers with raised, indurated borders, often occurring in perianal, perineal, or abdominal regions due to direct extension from intestinal amebiasis or hematogenous spread.

Apply this code when documentation clearly indicates a diagnosis of amebic skin ulceration, often confirmed by biopsy showing trophozoites of E. histolytica. This typically occurs in patients with a history of intestinal amebiasis or those residing in endemic areas.

• Differentiate from other causes of skin ulceration; physician documentation must specify "amebic."
• Consider sequencing with an intestinal amebiasis code (e.g., 006.0-006.3) if the skin lesion is a complication of an active intestinal infection.
• Ensure the documentation specifies "ulceration" to support this code, as other amebic skin conditions may exist.
