ICD-11 code 1F86.4 refers to cercarial dermatitis, also known as “swimmers itch.” This condition is a skin rash caused by an allergic reaction to certain parasites found in freshwater bodies, such as lakes and ponds. Cercarial dermatitis is commonly contracted by individuals who swim or wade in infested waters.
Symptoms of cercarial dermatitis typically include itching, redness, and small bumps or blisters on the skin. These symptoms can appear within a few hours of exposure to contaminated water and may last for a few days. In some cases, individuals may also experience a burning sensation or swelling at the site of infection.
While cercarial dermatitis is not a serious condition and usually resolves on its own, individuals may seek relief from symptoms through over-the-counter anti-itch creams or antihistamines. It is important to avoid scratching the affected area to prevent infection. If symptoms persist or worsen, medical attention may be necessary to rule out other skin conditions or infections.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1F86.4 for cercarial dermatitis is 72235003. Cercarial dermatitis, commonly known as swimmer’s itch, is a rash caused by an allergic reaction to parasites found in contaminated water. The SNOMED CT code provides a standardized way for healthcare professionals to accurately classify and track cases of cercarial dermatitis. By using this code, medical professionals can ensure consistency in reporting and data analysis for this specific condition. This simplifies communication across different healthcare settings and allows for more accurate monitoring of outbreaks and treatment outcomes. Overall, the SNOMED CT code 72235003 serves as a valuable tool in the management of cercarial dermatitis cases on a global scale.
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 1F86.4, also known as Cercarial dermatitis, typically manifest within hours after exposure to contaminated water. Affected individuals may experience itching, tingling, or burning sensations on the skin, particularly in areas that were in contact with the contaminated water. The skin may also develop a rash or red, raised bumps resembling hives.
As the condition progresses, the itching and discomfort may intensify, leading to the formation of small fluid-filled blisters on the skin. These blisters can be painful and may ooze or crust over. In some cases, individuals may also experience fever, headache, and fatigue as the body mounts an immune response to the parasites responsible for the condition.
The symptoms of Cercarial dermatitis can vary in severity depending on the individual’s immune response and the extent of exposure to contaminated water. While the skin rash and blisters are typically confined to the areas of skin that came into contact with the parasites, more widespread symptoms such as fever and fatigue can affect the entire body. If left untreated, the symptoms of Cercarial dermatitis may persist for several weeks before gradually improving on their own.
🩺 Diagnosis
Diagnosis of 1F86.4 (Cercarial dermatitis) typically involves a thorough physical examination of the affected areas of skin. The dermatologist will assess the appearance of the skin rash, looking for characteristic patterns and features commonly associated with cercarial dermatitis. The patient will also be asked about recent activities that may have exposed them to contaminated freshwater sources, such as swimming or wading in ponds or lakes.
In some cases, a skin biopsy may be performed to rule out other possible causes of the skin rash. During a skin biopsy, a small sample of skin tissue is collected and examined under a microscope for signs of inflammation or infection. This can help confirm the diagnosis of cercarial dermatitis and ensure that appropriate treatment is provided to the patient.
Laboratory tests are rarely used for diagnosing 1F86.4, as the condition is typically diagnosed based on clinical presentation and a history of exposure to contaminated water. However, in rare cases where the diagnosis is unclear, blood tests to check for elevated levels of eosinophils (a type of white blood cell associated with allergic reactions) may be performed. These tests can help support the diagnosis of cercarial dermatitis and guide treatment decisions for the patient.
💊 Treatment & Recovery
Treatment for 1F86.4, Cercarial dermatitis, typically involves topical corticosteroids to reduce inflammation and itching. In more severe cases, oral antihistamines may be prescribed to alleviate itching and discomfort. Over-the-counter anti-itch creams and lotions can also provide relief from symptoms.
In addition to medication, self-care measures can help with recovery from cercarial dermatitis. Avoiding further exposure to contaminated water sources is crucial to prevent reinfection. Keeping the affected skin clean and dry, as well as applying cool compresses, can help to soothe irritation and promote healing.
Recovery from cercarial dermatitis is usually rapid and uncomplicated with proper treatment and self-care strategies. Most cases of this condition resolve within a few weeks without any long-term complications. However, in rare instances where symptoms persist or become severe, it is recommended to seek medical attention for further evaluation and management.
🌎 Prevalence & Risk
In the United States, cercarial dermatitis, also known as swimmer’s itch, is relatively common, especially in areas with freshwater bodies such as lakes and ponds. The prevalence of 1F86.4 in the United States is estimated to be higher in the summer months when people are more likely to engage in water activities. Despite being a nuisance, cercarial dermatitis is generally not considered a serious health threat and tends to resolve on its own within a few days.
In Europe, cercarial dermatitis is also a known phenomenon, especially in countries with a significant number of freshwater lakes and rivers. The prevalence of 1F86.4 in Europe may vary depending on the region and the climate, with warmer and more humid areas potentially seeing higher rates of infection. Public health authorities in Europe typically advise avoiding swimming in stagnant or shallow water to reduce the risk of contracting cercarial dermatitis.
In Asia, cercarial dermatitis is not as widely reported as in the United States and Europe, but cases have been documented in countries with freshwater bodies such as lakes, rivers, and ponds. The prevalence of 1F86.4 in Asia may be underreported due to the lack of surveillance and diagnostic capabilities in some regions. As in other parts of the world, prevention measures such as avoiding swimming in areas with known snail populations and wearing protective clothing can help reduce the risk of cercarial dermatitis in Asia.
In Africa, cercarial dermatitis is less studied compared to other continents, but cases have been reported in regions with freshwater bodies. The prevalence of 1F86.4 in Africa may be influenced by factors such as climate, geography, and human behaviors related to water activities. More research is needed to better understand the scope of cercarial dermatitis in Africa and to develop targeted prevention and control strategies.
😷 Prevention
Preventing 1F86.4 (Cercarial dermatitis) can be achieved by taking certain precautions while engaging in activities that may expose individuals to the causative parasites. One important measure is to avoid swimming or wading in freshwater bodies where snails, the intermediate hosts of the parasites, are known to be present. Additionally, individuals can reduce the risk of infection by refraining from sitting or standing in the shallows of lakes, ponds, or rivers, where cercariae are more likely to be present in the water column.
Furthermore, wearing protective clothing, such as long pants and shirts, while engaging in water activities can act as a physical barrier against cercariae and reduce the likelihood of skin contact with the parasites. Showering or rinsing off immediately after leaving freshwater bodies is also recommended, as this can help to remove any parasites that may be present on the skin before they have a chance to burrow in and cause infection. Lastly, applying insect repellent with DEET to exposed skin can deter cercariae from penetrating the skin and thus reduce the risk of infection.
