Diseases Due To Trematodes – Definitions & ICD 11 Codes

Clonorchiasis

Definition of Clonorchiasis: A condition caused by an infection with the parasitic worm Clonorchis sinensis. This condition commonly presents with inflammation and obstruction of the biliary ducts. This condition may also present with abdominal pain, nausea, or diarrhoea. Transmission is commonly by ingestion of undercooked fish infected with parasitic cysts. Confirmation is by identification of Clonorchis sinensis eggs in a faecal sample.

ICD 11 Code For Clonorchiasis

 1F80  Clonorchiasis

Inclusions:

  • Chinese liver fluke disease
  • Oriental liver fluke disease

Dicrocoeliasis

Definition of Dicrocoeliasis: A disease caused by an infection with the parasitic worm Dicrocoelium dendriticum. This disease is commonly asymptomatic. This disease may present with cholecystitis, liver abscesses, or upper abdominal pain. Transmission is by ingestion of infected ants. Confirmation is by identification of Dicrocoelium dendriticum eggs in a faecal sample or duodenal fluid.

ICD 11 Code For Dicrocoeliasis

  1F81  Dicrocoeliasis

Inclusions:

  • Lancet fluke infection

Fascioliasis

Definition of Fascioliasis: A disease of the hepatic system, caused by an infection with the parasitic worm Fasciola. In the acute phase, this disease is characterised by upper abdominal pain, fever, urticaria, shortness of breath, nausea, or vomiting due to migration of the parasite from the intestines to the liver. In the chronic phase, this disease is characterised by cholestasis, cholangitis, pancreatitis, or gallstones. This disease may be asymptomatic. Transmission is by ingestion of undercooked contaminated aquatic plants or contaminated water. Confirmation is commonly by identification of Fasciola eggs in a faecal sample (after the individual has followed a liver-free diet prior to testing), or detection of antibodies against Fasciola.

  1F82  Fascioliasis

Inclusions:

  • Sheep liver fluke disease

Fasciolopsiasis

Definition of Fasciolopsiasis: A disease caused by an infection with the parasitic worm Fasciolopsis buski. This disease is characterised by abdominal pain or diarrhoea, or may be asymptomatic. This disease may also present with oedema of the face, abdomen, or legs, vomiting, anorexia, or intestinal obstruction. Transmission is by ingestion of undercooked contaminated aquatic plants. Confirmation is by identification of Fasciolopsis buski eggs in a faecal sample.

  1F83  Fasciolopsiasis

Opisthorchiasis

Definition of Opisthorchiasis: A disease caused by an infection with the parasitic worm Opisthorchis. This disease is commonly asymptomatic. In mild cases, this disease may present with dyspepsia, abdominal pain, diarrhoea, or constipation; in severe cases, this disease may present with hepatomegaly and malnutrition; in rare cases, this disease may present with cholangitis, cholecystitis, and cholangiocarcinoma. Transmission is by ingestion of infected undercooked freshwater fish. Confirmation is by identification Opisthorchis in a faecal sample.

ICD 11 Code For Opisthorchiasis

  1F84  Opisthorchiasis

Paragonimiasis

Definition of Paragonimiasis: A disease caused by an infection with the parasitic worm Paragonimus. This disease is characterised by cough or haemoptysis, or may be asymptomatic. This disease may present with other symptoms depending on the site where the parasite migrates to. Transmission is commonly by ingestion of undercooked contaminated crustaceans (crab or crayfish). Confirmation is commonly by identification of Paragonimus eggs in a sputum or faecal sample.

ICD 11 Code For Paragonimiasis

  1F85  Paragonimiasis

Inclusions:

  • lung fluke disease
  • infection due to paragonimus species
  • Infestation due to Paragonimus species

Schistosomiasis

Definition of Schistosomiasis: An infestation caused by helminths of the genus Schistosoma. The clinical features vary according to the species involved but the principal organs affected are the gastrointestinal tract and bladder.

ICD 11 Code For Schistosomiasis

  1F86  Schistosomiasis

Inclusions:

  • snail fever

1F86.0 Schistosomiasis due to Schistosoma haematobium

Definition of Schistosomiasis due to Schistosoma haematobium: A disease caused by an infection with the parasitic worm Schistosoma haematobium. This disease is characterised by haematuria, scarring, calcification, or squamous cell carcinoma. This disease may also present with embolic egg granulomas in the brain or spinal cord. Transmission is by direct contact with freshwater that has been contaminated with Schistosoma haematobium eggs or snails that carry Schistosoma haematobium.

1F86.1 Schistosomiasis due to Schistosoma mansoni

Definition of Schistosomiasis due to Schistosoma mansoni: A disease caused by an infection with the parasitic worm Schistosoma mansoni. This disease commonly presents with Katayama fever, hepatic perisinusoidal egg granulomas, Symmers’ pipe stem periportal fibrosis, or portal hypertension. This disease may also present with embolic egg granulomas in the brain or spinal cord. Transmission is by direct contact with freshwater that has been contaminated with Schistosoma mansoni eggs or snails that carry Schistosoma mansoni. Confirmation is by identification of the Schistosoma mansoni eggs in a faecal sample.

1F86.2 Schistosomiasis due to Schistosoma japonicum

Definition of Schistosomiasis due to Schistosoma japonicum: A disease caused by an infection with the parasitic worm Schistosoma japonicum. This disease is characterised by Katayama fever, hepatic perisinusoidal egg granulomas, Symmers’ pipe stem periportal fibrosis, or portal hypertension. This disease may also present with embolic egg granulomas in the brain or spinal cord. Transmission is by direct contact with freshwater that has been contaminated with Schistosoma japonicum eggs or snails that carry Schistosoma japonicum. Confirmation is by identification of the Schistosoma japonicum eggs in a faecal sample.

Inclusions:

  • Asiatic schistosomiasis

1F86.3 Other schistosomiases

1F86.4 Cercarial dermatitis

Definition of Cercarial dermatitis: A disease caused by an infection with the parasitic worm Schistosoma. This disease is characterised by tingling, burning, itching of the skin, small reddish pimples, or small blisters. Transmission is by direct contact with contaminated water. Confirmation is by identification of Schistosoma eggs in a faecal, urine, or blood sample.
