ICD-10 Code B78.7 – Disseminated strongyloidiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B78.7 – Disseminated strongyloidiasis
What it is
B78.7 identifies disseminated strongyloidiasis, a severe infection caused by Strongyloides stercoralis spreading beyond the usual intestinal or skin-limited disease. Use it when documentation describes widespread or hyperinfection-type involvement.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include severe gastrointestinal symptoms, pulmonary involvement, and signs of systemic illness in an immunocompromised patient.
When to use this code
Use this code when the provider documents disseminated strongyloidiasis, hyperinfection, or widespread Strongyloides infection. It may also apply when multiple organ systems are involved and the record clearly supports dissemination. If the note only states strongyloidiasis without extent, check documentation.
Do not use for
Do not use B78.7 for uncomplicated intestinal strongyloidiasis or for nonspecific parasitic infection. If dissemination is not documented, choose the more specific code supported by the record.
Coding tip
Code B78.7 only when the chart clearly documents dissemination or hyperinfection; otherwise, verify the infection extent before assigning it.
