Clonorchiasis

This code represents an infection caused by the liver fluke Clonorchis sinensis, also known as the Chinese liver fluke. The parasite primarily infects the bile ducts, gallbladder, and pancreatic ducts, leading to inflammation and various gastrointestinal and hepatobiliary symptoms.

Use this code when documentation confirms a diagnosis of clonorchiasis, typically identified through microscopic examination of stool samples for ova or molecular diagnostic tests. It is appropriate for both acute and chronic presentations of the infection.

• Ensure documentation specifies Clonorchis sinensis to differentiate from other trematode infections.
• Code any associated complications, such as cholangitis, cholelithiasis, or cholangiocarcinoma, in addition to the clonorchiasis.
• Verify the geographic origin or dietary history (e.g., consumption of raw freshwater fish) if available, as this can support the diagnosis.
