ICD-11 code 1F61 refers to anisakiasis, a parasitic infection caused by the larvae of certain types of nematodes (worms) found in fish and marine mammals. Ingesting raw or undercooked seafood, such as sushi or ceviche, is a common mode of transmission for this disease. Anisakiasis primarily affects the gastrointestinal tract and can result in symptoms such as abdominal pain, nausea, vomiting, and diarrhea.
The symptoms of anisakiasis can vary in severity depending on the individual’s immune response and the number of larvae ingested. In some cases, the larvae may penetrate the intestinal wall, causing tissue damage and an inflammatory response. Severe cases of anisakiasis may lead to complications such as gastrointestinal bleeding, bowel obstruction, or allergic reactions. Diagnosis of anisakiasis is typically based on a combination of clinical symptoms, imaging studies, and sometimes endoscopy to visualize and remove the larvae from the intestines.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1F61 (Anisakiasis) is 401017004. This code represents a parasitic disease caused by the ingestion of larvae of nematodes belonging to the Anisakidae family. Anisakiasis typically occurs when raw or undercooked seafood contaminated with these larvae is consumed by humans. Symptoms of Anisakiasis include abdominal pain, nausea, vomiting, and occasionally allergic reactions. The SNOMED CT code 401017004 is used to categorize and classify cases of Anisakiasis in electronic health records, facilitating accurate diagnosis and treatment. Healthcare professionals utilize this code to ensure proper documentation and coding of this parasitic infection. Overall, the equivalent SNOMED CT code for ICD-11 code 1F61 plays a crucial role in the healthcare system by enabling standardized communication and management of Anisakiasis cases.
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
Anisakiasis is a parasitic infection caused by consuming raw or undercooked seafood contaminated with Anisakis larvae. Symptoms of Anisakiasis typically manifest within hours of ingestion and include abdominal pain, nausea, vomiting, and diarrhea. These symptoms may be accompanied by a tingling sensation in the throat or coughing.
In severe cases, Anisakiasis can lead to intestinal obstruction or perforation, which may present with symptoms such as severe abdominal pain, fever, and chills. Additionally, allergic reactions to Anisakis larvae proteins can cause symptoms such as hives, shortness of breath, and anaphylaxis. It is important to seek medical attention promptly if any of these symptoms are present after consuming raw or undercooked seafood.
Diagnosis of Anisakiasis is usually based on clinical symptoms, dietary history, and imaging studies such as endoscopy or ultrasound. Treatment typically involves removal of the parasite through endoscopy or surgery, as well as administering medications to alleviate symptoms. Prevention of Anisakiasis includes thorough cooking or freezing of seafood before consumption to kill any parasites present.
🩺 Diagnosis
Diagnosis of 1F61 (Anisakiasis) typically involves a combination of clinical history, physical examination, and laboratory tests. Medical professionals may inquire about recent consumption of raw or undercooked fish, as this is a significant risk factor for developing anisakiasis.
Physical examination may reveal signs of gastrointestinal distress, such as abdominal pain, nausea, vomiting, or diarrhea. These symptoms, in combination with a history of raw fish consumption, may raise suspicion for anisakiasis. However, these findings are nonspecific and may resemble other gastrointestinal disorders, necessitating further diagnostic evaluation.
Laboratory tests are used to confirm the presence of Anisakis larvae in the body. Blood tests may show elevated levels of eosinophils, a type of white blood cell responsible for fighting parasitic infections. Imaging studies, such as ultrasound or endoscopy, may also be used to visualize the larvae in the stomach or intestines. In some cases, a tissue biopsy may be necessary to definitively diagnose anisakiasis.
Ultimately, the diagnosis of anisakiasis requires a high index of suspicion and a thorough evaluation by a healthcare provider. Prompt recognition and treatment of this parasitic infection are crucial to prevent complications and ensure a favorable outcome for the patient.
💊 Treatment & Recovery
Treatment for Anisakiasis typically involves removing the Anisakis larvae from the affected individual. This can be done through endoscopy or surgery, depending on the severity of the infection and the location of the larvae. In some cases, medication such as albendazole or mebendazole may be prescribed to kill the larvae.
Recovery from Anisakiasis can vary depending on the individual and the extent of the infection. Most people experience relief from symptoms shortly after treatment, but it may take some time for the digestive tract to fully heal. It is important for individuals with Anisakiasis to follow their healthcare provider’s recommendations for follow-up care and monitoring.
In some cases, complications such as intestinal obstruction or allergic reactions may occur as a result of Anisakiasis. Individuals experiencing severe symptoms or complications may require more intensive treatment or monitoring. It is essential for individuals to seek prompt medical attention if they suspect they have Anisakiasis to prevent further complications and ensure a full recovery.
🌎 Prevalence & Risk
In the United States, anisakiasis is considered a rare disease, with only a few reported cases each year. The majority of cases are found in states with coastal regions, where people consume raw or undercooked seafood. However, due to better awareness and increased regulations in the food industry, the prevalence of anisakiasis in the US is relatively low.
In Europe, anisakiasis is more commonly reported than in the United States. Countries such as Spain, Italy, and the Netherlands have higher rates of infection due to their consumption of raw and undercooked fish dishes. In these regions, anisakiasis is a recognized public health concern, with healthcare providers regularly monitoring and treating cases of the disease.
In Asia, particularly in countries like Japan and South Korea, anisakiasis is more prevalent than in other parts of the world. This is primarily due to the popularity of raw fish dishes such as sushi and sashimi, which are commonly consumed by the population. As a result, healthcare professionals in these regions are well-versed in diagnosing and treating cases of anisakiasis.
In Africa, the prevalence of anisakiasis is relatively low compared to other continents. This can be attributed to the lower consumption of raw fish in many African countries, as well as the lack of awareness about the disease. However, with increasing globalization and the popularity of international cuisines, it is important for healthcare providers in Africa to be educated about anisakiasis and its symptoms.
😷 Prevention
To prevent 1F61 (Anisakiasis), it is crucial to properly handle and cook raw or undercooked fish and seafood. Thoroughly freezing fish at -20°C for 7 days, or at -35°C for 15 hours, can kill the Anisakis larvae. In addition, consuming only fish that has been properly cooked or treated according to recommended guidelines can greatly reduce the risk of infection.
Furthermore, avoiding consumption of raw or undercooked fish dishes, such as ceviche or sushi, can also help prevent the transmission of Anisakis larvae. Properly inspecting fish before consumption for any visible signs of larvae or parasites can provide an additional layer of protection. It is advisable to source fish and seafood products from reputable suppliers who adhere to strict food safety standards to minimize the risk of Anisakiasis.
