Diphyllobothriasis
ICD-10 B70.1 is a billable code used to indicate a diagnosis of diphyllobothriasis.
Diphyllobothriasis is a helminthic infection caused by the ingestion of the larval form of the tapeworm Diphyllobothrium latum, commonly found in freshwater fish. This parasitic disease is prevalent in regions where raw or undercooked fish is consumed, particularly in parts of Europe, Asia, and North America. The adult tapeworm resides in the intestines of humans and can grow up to 10 meters in length. Symptoms may include abdominal discomfort, diarrhea, and weight loss, although many infected individuals remain asymptomatic. The infection can lead to vitamin B12 deficiency and subsequent megaloblastic anemia due to the tapeworm's ability to absorb vitamin B12 from the host. Diagnosis is typically confirmed through stool examination for eggs or proglottids. Treatment involves the administration of antiparasitic medications such as praziquantel or niclosamide, which are effective in eliminating the adult tapeworm from the host. Preventive measures include proper cooking of fish and avoiding consumption of raw or undercooked fish dishes.
Detailed patient history, including dietary habits and symptomatology, along with laboratory results confirming the presence of the parasite.
Patients presenting with gastrointestinal symptoms after consuming raw fish, or those with unexplained anemia.
Consideration of co-infections and the need for comprehensive treatment plans.
Endoscopic findings, imaging studies, and laboratory results that support the diagnosis of diphyllobothriasis.
Patients with chronic gastrointestinal symptoms and unexplained weight loss.
Documentation of any concurrent gastrointestinal disorders that may complicate the diagnosis.
Used when stool tests are performed to confirm the presence of Diphyllobothrium latum.
Documentation of symptoms and rationale for testing.
Infectious disease specialists should ensure comprehensive testing for other potential infections.
Common symptoms include abdominal pain, diarrhea, weight loss, and in some cases, vitamin B12 deficiency leading to anemia.
Diagnosis is typically made through stool examination to identify eggs or proglottids of the tapeworm.
Antiparasitic medications such as praziquantel or niclosamide are commonly used to treat diphyllobothriasis.
