ICD-11 code 1F91 refers to the diagnosis of diphyllobothriasis and sparganosis, two parasitic infections caused by tapeworms and flatworms, respectively. These infections typically affect the gastrointestinal system in humans, causing symptoms such as abdominal pain, diarrhea, and weight loss.
Diphyllobothriasis is caused by a type of tapeworm found in raw or undercooked fish. Infections often result from consuming contaminated fish or water sources. Symptoms of diphyllobothriasis may include abdominal discomfort, weakness, and a deficiency of vitamin B12, leading to anemia.
Sparganosis, on the other hand, is caused by a flatworm larvae known as sparganum. This parasite can infect various organs in the human body, leading to symptoms such as pain, swelling, and migration of the parasite under the skin. Sparganosis is often linked to eating raw or undercooked animals, especially frogs or snakes.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1F91 for diphyllobothriasis and sparganosis is 425909008. SNOMED CT, the Systematized Nomenclature of Medicine Clinical Terms, is a standardized medical vocabulary used by healthcare professionals worldwide to ensure consistency in electronic health records and information exchange. This specific code allows for accurate identification and communication of the diagnoses of diphyllobothriasis and sparganosis, which are parasitic infections caused by tapeworms. By utilizing the SNOMED CT code 425909008, healthcare providers can easily document and track the treatment and outcomes of patients with these conditions, enabling better patient care and facilitating research and data analysis in the medical field. The use of standardized codes like SNOMED CT promotes interoperability and enhances the efficiency and accuracy of healthcare information management.
In the United States, ICD-11 is not yet in use. The U.S. is currently using ICD-10-CM (Clinical Modification), which has been adapted from the WHO’s ICD-10 to better suit the American healthcare system’s requirements for billing and clinical purposes. The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Diphyllobothriasis is caused by infection with Diphyllobothrium tapeworms, specifically Diphyllobothrium latum and Diphyllobothrium nihonkaiense. The most common symptom is the passage of proglottids in the stool, which may be accompanied by abdominal pain, diarrhea, and weight loss. Some individuals may also experience vitamin B12 deficiency and megaloblastic anemia due to the tapeworm’s absorption of this essential nutrient.
In more severe cases of diphyllobothriasis, patients may present with symptoms such as intestinal obstruction, bile duct obstruction, or cholangitis. Rarely, migration of tapeworm larvae to extraintestinal sites such as the liver, spleen, or pancreas can cause localized tissue damage and inflammation. Diagnosis of diphyllobothriasis is typically made through the identification of tapeworm eggs or proglottids in the stool, although serologic tests and imaging studies may be necessary in certain cases.
Sparganosis is a rare parasitic infection caused by the larvae of Spirometra tapeworms, specifically Spirometra mansoni and Spirometra mansonoides. Symptoms of sparganosis vary depending on the location of the parasite larvae in the body. Cutaneous sparganosis presents with subcutaneous nodules or swelling, while ocular sparganosis can cause visual disturbances or inflammation of the eye.
In cases of visceral sparganosis, patients may experience abdominal pain, nausea, or symptoms related to organ dysfunction. Sparganosis can also affect the central nervous system, leading to symptoms such as headache, seizures, or neurologic deficits. Diagnosis of sparganosis is challenging and may involve histologic examination of biopsy specimens, serologic tests, or imaging studies to identify the presence of Spirometra larvae in the affected tissues.
🩺 Diagnosis
Diagnosis of 1F91 (Diphyllobothriasis and sparganosis) often involves a combination of clinical evaluation, imaging studies, and laboratory tests. Patients presenting with symptoms such as abdominal pain, diarrhea, or weight loss may prompt further investigation for parasitic infections. A thorough history of travel, dietary habits, and possible exposure to contaminated water sources can help guide the diagnostic process.
Imaging studies such as ultrasound, computed tomography (CT) scans, or magnetic resonance imaging (MRI) can be used to detect the presence of parasites, cysts, or lesions in various organs. These studies can help identify the location and extent of the infection, aiding in treatment planning and monitoring the response to therapy. Additionally, endoscopy or colonoscopy may be performed to visualize the gastrointestinal tract and collect tissue samples for further analysis.
Laboratory tests play a crucial role in confirming the diagnosis of 1F91. Stool samples can be examined for the presence of parasite eggs or larvae using microscopy techniques. Serologic tests, such as enzyme-linked immunosorbent assays (ELISA) or polymerase chain reaction (PCR) tests, can detect specific antibodies or genetic material of the parasites in the blood. These tests can provide definitive evidence of infection and help differentiate between different parasitic species causing similar symptoms. Collaborative efforts between physicians, radiologists, and laboratory technicians are essential in achieving an accurate and timely diagnosis of diphyllobothriasis and sparganosis.
💊 Treatment & Recovery
Treatment for Diphyllobothriasis involves the administration of antihelminthic medications such as praziquantel and niclosamide. These drugs are effective in killing the tapeworms in the intestines. In some cases, a repeat dose may be necessary to ensure complete eradication of the parasite.
In cases of sparganosis, the treatment involves surgical removal of the larvae. This may require the expertise of a surgeon to ensure that all infected tissue is removed. In some cases, antiparasitic medications may be prescribed to help kill any remaining parasites in the body.
Recovery from Diphyllobothriasis and sparganosis involves monitoring for any signs of relapse. Patients are typically advised to follow up with their healthcare provider to ensure that the infection has been completely cleared. In cases where surgical removal was necessary, patients may need to undergo post-operative care to minimize the risk of complications. Follow-up testing may also be recommended to confirm successful treatment.
🌎 Prevalence & Risk
In the United States, 1F91 (Diphyllobothriasis and sparganosis) is considered rare, with sporadic cases reported mainly in travelers returning from endemic regions. The prevalence of Diphyllobothriasis is estimated to be less than 1% in the general population, with most cases occurring in immigrants or individuals consuming raw fish. Sparganosis is even rarer, with only a few documented cases in the United States.
In Europe, the prevalence of 1F91 (Diphyllobothriasis and sparganosis) varies depending on the region. In countries with a tradition of consuming raw or undercooked fish, such as Scandinavian countries, the prevalence of Diphyllobothriasis is higher. Sparganosis, on the other hand, is extremely rare in Europe, with only isolated cases reported in countries like Spain and France.
In Asia, 1F91 (Diphyllobothriasis and sparganosis) are more commonly reported, particularly in countries where raw fish is a dietary staple. In Japan, for example, Diphyllobothriasis is a well-known parasitic infection, with a prevalence of around 5% in certain regions. Sparganosis is also more common in Asia, with cases reported in countries like China, Korea, and Thailand.
In Africa, the prevalence of 1F91 (Diphyllobothriasis and sparganosis) is not well-documented, as these parasitic infections are often overshadowed by other more prevalent diseases. However, sporadic cases of Diphyllobothriasis have been reported in countries like South Africa and Egypt. Sparganosis, on the other hand, is rarely reported in Africa, with only a few isolated cases documented.
😷 Prevention
To prevent 1F91 (Diphyllobothriasis), proper sanitation and hygiene practices are essential. Cooking fish thoroughly and avoiding the consumption of raw or undercooked fish can help prevent infection. Additionally, avoiding the consumption of contaminated water sources and properly washing fruits and vegetables before consumption can reduce the risk of contracting Diphyllobothriasis. It is also important to avoid ingesting raw or undercooked meat from potentially infected animals.
Sparganosis, on the other hand, can be prevented by avoiding the consumption of raw or undercooked frog, snake, or bird meat which may be contaminated with spargana larvae. Similarly, drinking clean, filtered water and avoiding contact with potentially contaminated water sources can help lower the risk of sparganosis infection. Proper sanitation practices, such as washing hands before handling food and avoiding the use of potentially contaminated utensils, can also help prevent the spread of spargana larvae. Overall, maintaining good personal hygiene and being cautious about the sources of food and water can greatly reduce the risk of contracting sparganosis.
🦠 Similar Diseases
