A07.9

What This Code Means

This code describes an infection of the intestines caused by parasitic organisms called protozoa, but the specific type of protozoa has not been identified or documented. Common symptoms include diarrhea, abdominal pain, and nausea.

Coding Tips

• •Use this code only when the specific protozoal organism cannot be determined; if the organism is identified (such as giardia, cryptosporidium, or entamoeba), use the more specific A07.0-A07.8 codes instead
• •Document any associated symptoms like diarrhea (A09) or dehydration to provide a complete clinical picture, and query the provider if additional diagnostic testing results become available
