Unspecified protozoal intestinal disease

This code represents an intestinal infection caused by protozoa where the specific type of protozoal organism is not identified in the medical record. It indicates a confirmed protozoal etiology for an intestinal disease, but lacks further specificity regarding the pathogen.

Apply this code when documentation clearly indicates a protozoal intestinal infection, but the physician's diagnosis or lab results do not specify the exact protozoal species (e.g., amoebiasis, giardiasis, cryptosporidiosis). This is a diagnosis of exclusion when more specific protozoal codes cannot be supported.

• Always seek clarification from the provider if a more specific protozoal organism is suspected or known, as more precise codes exist.
• Do not use this code if the intestinal disease is known to be caused by bacteria, viruses, or other non-protozoal pathogens.
• Ensure documentation supports an intestinal manifestation; other protozoal infections affecting different body systems would use different codes.
