Schistosomiasis due to schistosoma japonicum

This code identifies an infection caused by the parasitic trematode Schistosoma japonicum, commonly known as Oriental schistosomiasis. This chronic disease primarily affects the liver and intestines, leading to symptoms such as abdominal pain, diarrhea, hepatosplenomegaly, and portal hypertension.

Use this code when documentation explicitly states a diagnosis of schistosomiasis confirmed to be caused by Schistosoma japonicum. This typically follows laboratory identification of S. japonicum eggs in stool or tissue samples, or serological evidence in endemic areas.

• Differentiate from other forms of schistosomiasis; ensure the specific species japonicum is documented.
• Code any associated manifestations or complications, such as portal hypertension or liver fibrosis, as secondary diagnoses.
• Review patient's travel history to endemic regions (e.g., East Asia) as supporting documentation.
