Fasciolopsiasis

Fasciolopsiasis is a parasitic infection caused by the trematode Fasciolopsis buski, commonly known as the giant intestinal fluke. This infection primarily affects the small intestine, leading to symptoms such as abdominal pain, diarrhea, malabsorption, and in severe cases, intestinal obstruction and edema. It is acquired through the ingestion of metacercariae on aquatic plants, particularly water caltrop or water chestnut.

Use this code for documented cases of Fasciolopsis buski infection confirmed by stool examination identifying eggs or adult flukes, or by clinical presentation in endemic areas with a history of consuming contaminated aquatic plants. This code is appropriate when the patient exhibits signs and symptoms consistent with fasciolopsiasis.

• Ensure documentation specifies Fasciolopsis buski to differentiate from other fluke infections.
• Do not confuse with fascioliasis (liver fluke infection), which is caused by Fasciola hepatica or Fasciola gigantica and coded elsewhere.
• Consider co-occurring nutritional deficiencies or secondary infections as additional diagnoses if documented.
