ICD-10 Code B60 – Other protozoal diseases, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B60 – Other protozoal diseases, not elsewhere classified
What it is
B60 identifies protozoal infections that do not fit a more specific ICD-10-CM code. Use it when the record documents an unspecified or other protozoal disease and no narrower category applies.
Clinical signs
Clinical features vary; refer to documentation. Protozoal infections may present with systemic or organ-specific symptoms, depending on the organism and site involved.
When to use this code
Use B60 when the provider documents a protozoal infection but does not name a specific protozoal disease that has its own code. It may also apply when the chart states “other protozoal disease” or similar wording. Check documentation carefully before assigning this code.
Do not use for
Do not use B60 if the organism is identified and a more specific ICD-10-CM code exists. Do not use it for non-protozoal parasitic infections or when the record does not support a protozoal diagnosis.
Coding tip
Query for the exact protozoal organism or disease name whenever possible; B60 is a catch-all code and should be used only when specificity is unavailable.
