ICD-11 code 1F66.1 refers to Mansonelliasis, which is a parasitic disease caused by infection with the Mansonella worm. This disease is prevalent in certain tropical regions of Africa and Latin America, typically affecting individuals who reside in rural areas.
Mansonelliasis is transmitted to humans through the bite of infected blackflies or midges. The symptoms of Mansonelliasis can vary but commonly include skin rashes, itching, and swelling of lymph nodes. In some cases, individuals with Mansonelliasis may also experience joint pain and eye problems.
Diagnosis of Mansonelliasis is typically confirmed through laboratory tests that detect the presence of Mansonella worms in blood samples. Treatment options for Mansonelliasis may include antiparasitic medications such as ivermectin or albendazole. Preventive measures such as wearing protective clothing and using insect repellent can help reduce the risk of Mansonelliasis infection.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1F66.1, which represents Mansonelliasis, is 44611003. This code specifically refers to a parasitic disease caused by Mansonella species, transmitted to humans through the bites of infected blackflies. Patients infected with Mansonelliasis may experience symptoms such as fever, joint pain, and skin rashes. The disease is commonly found in regions with heavy blackfly populations, including parts of Africa, South America, and the Caribbean. Diagnosis of Mansonelliasis typically involves microscopic examination of blood samples to detect the presence of microfilariae. Treatment may involve the use of antiparasitic medications to eliminate the parasites from the body and alleviate symptoms. Early detection and management of Mansonelliasis are important in preventing further complications and spread of the disease.
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
Symptoms of Mansonelliasis, caused by infection with Mansonella parasites, vary depending on the species involved and the individual’s immune response. Common symptoms include itching, skin rashes, and occasional joint pain. These symptoms typically occur months to years after infection and can be chronic in nature.
Additionally, individuals with Mansonelliasis may experience eye symptoms such as redness, swelling, and blurry vision. In some cases, the presence of adult worms in the eye can lead to more severe manifestations such as cataracts or glaucoma. Eye symptoms may persist for long periods, affecting the individual’s quality of life and potentially leading to vision impairment.
In severe cases of Mansonelliasis, individuals may experience systemic symptoms such as fever, fatigue, and weight loss. These symptoms can be indicative of a more widespread infection or complications arising from the presence of the parasites in the body. Systemic symptoms often prompt individuals to seek medical attention and may require more aggressive treatment approaches to manage the condition effectively.
🩺 Diagnosis
Diagnosis of 1F66.1 (Mansonelliasis) typically involves a combination of clinical symptoms, physical examination, and laboratory tests. Patients with Mansonelliasis may present with symptoms such as itching, rash, and swelling in the affected areas. However, these symptoms are not specific to Mansonelliasis and can be seen in other parasitic infections as well.
During the physical examination, healthcare providers may look for characteristic findings such as nodules under the skin that contain adult worms. These nodules are typically painless and can be felt under the skin of the affected individual. However, not all patients with Mansonelliasis may have detectable nodules during the examination.
Laboratory tests are essential for confirming the diagnosis of Mansonelliasis. Blood samples may be taken from the patient and examined under a microscope for the presence of microfilariae, which are the larval form of the parasite. The timing of the blood sample collection is crucial, as the microfilariae may not be present in the blood at all times but may have periodic patterns of circulation. Apart from blood samples, other diagnostic tests such as skin biopsies or polymerase chain reaction (PCR) testing may also be performed to confirm the diagnosis of Mansonelliasis.
💊 Treatment & Recovery
Treatment for 1F66.1 (Mansonelliasis) typically involves prescription medications to target the parasites causing the infection. Commonly used medications include ivermectin and albendazole, which are effective in reducing the number of parasites in the bloodstream. These medications may need to be taken for several days to weeks, depending on the severity of the infection.
In some cases, individuals with Mansonelliasis may experience symptoms such as itching, swelling, and skin rash. These symptoms can be managed with over-the-counter antihistamines or topical corticosteroids to reduce discomfort. It is important to consult with a healthcare provider before using any medications to ensure they are safe and effective for the specific individual.
Recovery from Mansonelliasis can vary depending on the individual’s immune response and overall health. In most cases, symptoms of the infection will improve with proper treatment and rest. It is essential to follow the prescribed treatment regimen and attend follow-up appointments with a healthcare provider to monitor progress and ensure the infection is fully cleared. Additionally, individuals should take preventive measures to avoid re-infection, such as using insect repellent and wearing long clothing to prevent mosquito bites.
🌎 Prevalence & Risk
In the United States, Mansonelliasis is considered a rare tropical disease, with only a few reported cases each year. The majority of cases in the U.S. are typically found in individuals who have traveled to endemic regions in Africa or Central and South America. Due to the limited presence of the disease in the country, Mansonelliasis is not routinely tested for or included in health statistics.
In Europe, Mansonelliasis is virtually nonexistent, with only sporadic cases reported in individuals who have traveled to endemic areas. The low prevalence of the disease in Europe can be attributed to the absence of the primary vectors responsible for transmitting Mansonella spp. parasites to humans. Health authorities in European countries typically do not consider Mansonelliasis a significant public health concern.
In Asia, Mansonelliasis is more prevalent in certain regions, particularly in tropical and subtropical areas where the primary vectors of the disease, such as biting midges and blackflies, are abundant. Countries in Southeast Asia, including Thailand, Indonesia, and the Philippines, have reported cases of Mansonelliasis among both locals and travelers. The prevalence of Mansonelliasis in Asia varies depending on factors such as climate, geography, and vector populations.
In Africa, Mansonelliasis is endemic in several countries, particularly in regions with dense rainforests and high populations of blackflies and biting midges. Countries in Central and West Africa, such as Nigeria, Cameroon, and the Democratic Republic of the Congo, have reported high rates of Mansonelliasis cases. The prevalence of Mansonelliasis in Africa is influenced by factors such as poverty, lack of access to healthcare, and limited vector control measures.
😷 Prevention
To prevent 1F66.1 (Mansonelliasis), it is important to take preventive measures to reduce the risk of infection. One of the most effective ways to prevent Mansonelliasis is to avoid being bitten by infected flies. This can be achieved by wearing long sleeves and pants, using insect repellent, and sleeping under a mosquito net in areas where Mansonelliasis is prevalent.
Additionally, avoiding areas where Mansonelliasis is common, such as tropical regions, can help reduce the risk of infection. Travelers to these regions should take extra precautions to protect themselves from insect bites and should be aware of the symptoms of Mansonelliasis in case of exposure.
Furthermore, community-wide efforts to control the population of biting flies, such as spraying insecticides and draining standing water where the flies breed, can help reduce the prevalence of Mansonelliasis. Educating the public about the risks of the disease and promoting preventive measures can also play a crucial role in preventing the spread of Mansonelliasis.
