Code Description

ICD-10 A07 is a used to indicate a diagnosis of other protozoal intestinal diseases.

Key Diagnostic Point:

This code encompasses various intestinal diseases caused by protozoa that do not fall under more specific categories. These diseases can lead to gastrointestinal symptoms such as diarrhea, abdominal pain, and malabsorption.
