Fascioliasis

Fascioliasis is a parasitic infection caused by liver flukes, primarily Fasciola hepatica or Fasciola gigantica. The infection typically occurs after ingesting metacercariae on contaminated aquatic plants, leading to inflammation and damage in the liver and bile ducts. Symptoms can range from acute abdominal pain, fever, and hepatomegaly to chronic biliary obstruction and cholangitis.

This code is used when documentation confirms a diagnosis of fascioliasis, often through serological tests, stool examination for eggs, or imaging studies showing liver lesions or biliary abnormalities consistent with fluke infection. It applies to both acute and chronic presentations of the disease.

• Ensure documentation specifies fascioliasis to differentiate from other helminthic infections.
• Consider co-occurring conditions such as cholangitis or liver abscess, which may require additional codes.
• Review the patient's travel history and dietary habits, as these can support the diagnosis.
