Other specified protozoal diseases

This code signifies protozoal infections that are not specifically classified elsewhere in the ICD-10-CM system. It covers a range of parasitic diseases caused by single-celled eukaryotic organisms, excluding those with dedicated codes. Examples might include less common or newly identified protozoal pathogens.

Use this code when the medical record clearly documents a protozoal infection, but the specific type of protozoa does not have a more precise ICD-10-CM code. This typically applies when the physician's diagnosis specifies a protozoal disease that falls outside of categories like malaria, leishmaniasis, trypanosomiasis, or toxoplasmosis. Documentation should identify the protozoal etiology.

• Always attempt to code to the highest level of specificity; only use this code when a more precise protozoal disease code is unavailable.
• Review documentation for the specific protozoal organism identified to ensure no more specific code exists within B50-B64.
• Consider sequencing this code after any associated manifestations or complications of the protozoal infection, if applicable.
