Dicroceliasis

This code represents an infection caused by the liver fluke Dicrocoelium dendriticum, commonly known as the lancet fluke. The parasite resides in the bile ducts of the definitive host, leading to inflammation and potential obstruction.

Use this code when documentation confirms a diagnosis of dicroceliasis, typically identified through the presence of Dicrocoelium dendriticum eggs in stool or duodenal aspirate samples. This diagnosis is often made in patients with a history of consuming raw or undercooked infected ants, which serve as the second intermediate host.

• Ensure the documentation specifically identifies Dicrocoelium dendriticum to differentiate from other trematode infections.
• Consider co-occurring conditions such as cholangitis or cholelithiasis, which may be complications of chronic dicroceliasis.
• Do not confuse with other helminthic infections of the biliary tract, such as fascioliasis (liver fluke) or clonorchiasis (Chinese liver fluke).
