Cutaneous strongyloidiasis

This code represents a parasitic skin infection caused by Strongyloides stercoralis larvae migrating through the skin. It typically manifests as a serpiginous, rapidly advancing, pruritic rash, often referred to as larva currens. This condition is a dermatological manifestation of strongyloidiasis.

Use this code when documentation clearly indicates a diagnosis of cutaneous strongyloidiasis, characterized by the distinctive skin lesions caused by larval migration. This diagnosis is often supported by clinical presentation and may be confirmed by identification of larvae in skin biopsies or stool examination for systemic infection.

• Do not confuse with other forms of larva migrans (e.g., cutaneous larva migrans caused by hookworms), which have different ICD-10-CM codes.
• Consider co-coding with codes for systemic strongyloidiasis (e.g., B78.0 for intestinal strongyloidiasis) if the skin manifestation is part of a broader infection.
• Ensure the documentation specifies "cutaneous" strongyloidiasis to accurately assign this code.
