Intestinal trichomoniasis

This code represents a parasitic infection of the intestines caused by Trichomonas hominis or other Trichomonas species. While often asymptomatic, it can manifest with gastrointestinal symptoms such as diarrhea, abdominal pain, and flatulence, particularly in immunocompromised individuals.

Apply this code when documentation confirms a diagnosis of trichomoniasis specifically affecting the intestinal tract, typically identified via stool examination. This diagnosis is often made in patients presenting with unexplained chronic diarrhea or other GI disturbances where parasitic causes are being investigated.

• Differentiate from urogenital trichomoniasis (131.0x), which is caused by Trichomonas vaginalis and affects different body systems.
• If the patient is immunocompromised, consider additional codes for the underlying immunocompromised state.
• Ensure the physician's documentation explicitly states "intestinal trichomoniasis" or identifies Trichomonas species found in stool samples.
