Disseminated strongyloidiasis

This code represents a severe, life-threatening form of strongyloidiasis where the Strongyloides stercoralis parasite disseminates beyond the typical gastrointestinal and pulmonary systems. It involves widespread larval migration to organs such as the central nervous system, liver, heart, or endocrine glands, often leading to sepsis and multi-organ failure. This condition typically occurs in immunocompromised individuals.

Use this code when documentation clearly indicates systemic dissemination of Strongyloides larvae to multiple organs beyond the usual migratory pathways. This diagnosis is often supported by identification of larvae in normally sterile sites (e.g., CSF, ascites, pleural fluid) or biopsy of affected organs. It is crucial to differentiate from uncomplicated strongyloidiasis or hyperinfection syndrome, which have distinct clinical presentations and coding.

• Ensure documentation explicitly states "disseminated" strongyloidiasis or describes widespread organ involvement beyond the GI tract and lungs.
• Do not confuse with B78.1 (Cutaneous strongyloidiasis) or B78.0 (Intestinal strongyloidiasis) which represent less severe forms.
• Always code any associated manifestations or complications, such as sepsis (A41.9), meningitis (G00.9), or pneumonia (J18.9), as additional diagnoses.
