Schistosomiasis due to Schistosoma mansoni

This code identifies an infection caused by the parasitic flatworm Schistosoma mansoni, specifically affecting the intestines. This helminthic infection, commonly known as intestinal schistosomiasis, results from the parasite's eggs lodging in the bowel wall, leading to inflammation and various gastrointestinal symptoms.

Use this code when documentation confirms a diagnosis of schistosomiasis, and laboratory testing (e.g., stool examination for ova and parasites, serology) specifically identifies Schistosoma mansoni as the causative agent. This code is appropriate for both acute and chronic presentations of intestinal schistosomiasis.

• Ensure the documentation explicitly states Schistosoma mansoni to differentiate from other schistosome species.
• Code any associated manifestations or complications (e.g., portal hypertension, hepatosplenomegaly) separately.
• Do not confuse with schistosomiasis affecting other organ systems, which are classified under different codes.
