ICD-10 Code B65.8 – Other schistosomiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B65.8 – Other schistosomiasis
What it is
B65.8 identifies schistosomiasis caused by species or presentations not classified elsewhere. Use it when the record documents schistosomiasis, but the specific type does not match another listed code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have findings consistent with parasitic infection, but the exact organ involvement or species should be confirmed before coding.
When to use this code
Use B65.8 when the provider documents other schistosomiasis, schistosomiasis NOS, or an unspecified schistosomal infection that is not assigned to a more specific code. It is appropriate when the chart supports schistosomiasis but does not identify a different indexed category. Check documentation if the species is named.
Do not use for
Do not use this code when the record clearly identifies another schistosomiasis code or a different parasitic disease. If the documentation is vague, confirm the diagnosis rather than assuming B65.8.
Coding tip
Match the code to the documented species or subtype first; if that detail is missing, verify whether B65.8 is the best available choice.
