ICD-10 Code B65.2 – Schistosomiasis due to Schistosoma japonicum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B65.2 – Schistosomiasis due to Schistosoma japonicum
What it is
B65.2 identifies schistosomiasis caused by Schistosoma japonicum, a parasitic infection acquired from contaminated freshwater exposure. Use it when documentation names this specific species.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include abdominal pain, diarrhea, fever, or signs of chronic hepatosplenic disease in established infection.
When to use this code
Use B65.2 when the provider documents Schistosoma japonicum infection, schistosomiasis due to that species, or a confirmed species-specific diagnosis. It is appropriate for active infection and for encounters where the diagnosis is being managed or evaluated.
If the record only says schistosomiasis without species, check documentation before coding this specific code. You need clear linkage to Schistosoma japonicum to avoid miscoding.
Do not use for
Do not use this code for other schistosoma species, such as S. mansoni or S. haematobium. Check documentation when the species is unspecified or when another parasitic disease is recorded.
Coding tip
Code B65.2 only when the organism is explicitly documented; otherwise, query the record for species confirmation.
