Unspecified protozoal disease

This code signifies a protozoal infection where the specific type of protozoan causing the disease has not been identified or documented. It indicates the presence of a parasitic infection caused by a single-celled eukaryotic organism, but without further diagnostic specificity.

This code is appropriate when documentation confirms a protozoal disease but lacks information to classify it to a more specific code within categories B50-B64. It should be used only when the causative protozoan cannot be determined, even after reviewing all available clinical information.

• Avoid using this code if a more specific protozoal infection (e.g., malaria, leishmaniasis, toxoplasmosis) can be identified from the medical record.
• Query the provider for clarification if "protozoal infection" is documented without further detail, to ascertain if a more specific diagnosis is known.
• This code should be a last resort when no other specific protozoal disease code can be assigned.
