Protozoal intestinal disease, unspecified

This code signifies an intestinal infection caused by a protozoan parasite when the specific type of protozoa is not identified. It indicates a general diagnosis of a parasitic gastrointestinal illness without further pathogen specification.

This code is appropriate when a patient presents with symptoms of a protozoal intestinal infection (e.g., diarrhea, abdominal pain, nausea) and diagnostic testing confirms a protozoal etiology, but the specific organism (e.g., Giardia, Cryptosporidium, Entamoeba) is not documented or is pending. It should be used when the provider's documentation explicitly states "protozoal intestinal disease, unspecified" or similar language indicating an unconfirmed specific protozoal agent.

• Avoid using this code if a more specific protozoal infection is documented (e.g., giardiasis, cryptosporidiosis).
• Query the provider for a more specific diagnosis if possible, especially if laboratory results are available.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter and no other definitive diagnosis is established.
