Cutaneous amebiasis

This code describes an infection of the skin caused by the parasite Entamoeba histolytica. It typically manifests as ulcerative lesions, nodules, or abscesses on the skin, often in perianal, genital, or abdominal regions, resulting from direct inoculation or dissemination from an internal amebic infection.

Use this code when documentation clearly indicates a diagnosis of cutaneous amebiasis, confirmed by biopsy, microscopic examination, or serology. This condition is often seen in patients with underlying intestinal amebiasis or those in endemic areas.

• Differentiate from other skin infections; ensure documentation specifies amebic etiology.
• Consider sequencing this code after a code for intestinal amebiasis (A06.0-A06.9) if the cutaneous manifestation is secondary.
• Look for terms like "amebic skin ulcer," "cutaneous amebic abscess," or "extraintestinal amebiasis of skin."
