ICD-11 code 1F6A.1 refers to onchocerciasis of the skin, a parasitic infection caused by the filarial worm Onchocerca volvulus. This condition is transmitted through the bites of infected blackflies and can lead to chronic itching, skin lesions, and visual impairment if left untreated.
Onchocerciasis is a neglected tropical disease found primarily in sub-Saharan Africa, Latin America, and Yemen. The disease is characterized by the presence of nodules under the skin containing adult worms, as well as microfilariae circulating in the blood and skin tissues.
Early diagnosis and treatment with antiparasitic medications can help control the symptoms of onchocerciasis and prevent long-term complications. Public health efforts, such as mass drug administration campaigns and vector control interventions, are crucial in reducing the burden of this disease in endemic regions.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 1F6A.1, which represents Onchocerciasis of the skin, is 23650009. This code specifically identifies the condition where the skin is affected by the parasitic worm Onchocerca volvulus. SNOMED CT codes are used to standardize terminology in the healthcare industry, allowing for consistency in recording and reporting medical conditions.
Onchocerciasis is commonly known as river blindness and is a neglected tropical disease prevalent in parts of Africa, Latin America, and Yemen. The use of SNOMED CT codes facilitates accurate communication among healthcare professionals worldwide, aiding in the diagnosis and treatment of various diseases. By assigning a unique code to each medical condition, healthcare providers can quickly access information about the disease and its characteristics, leading to better patient care and outcomes.
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 1F6A.1 (Onchocerciasis of the skin) typically manifest as a result of the body’s immune response to the presence of the microscopic worm Onchocerca volvulus. Common indicators of this condition include itching and skin rashes. These symptoms are often localized to the areas where the adult worms reside in the subcutaneous tissues.
In addition to itching and skin rashes, individuals affected by Onchocerciasis of the skin may also experience the formation of nodules beneath the skin. These nodules are caused by the body’s reaction to the presence of the worms and are typically firm to the touch. The nodules are a hallmark symptom of this condition and may be found in various locations on the body.
As the disease progresses, individuals with Onchocerciasis of the skin may develop skin depigmentation. This condition, known as leopard skin, results in patchy areas of lighter-colored skin due to the damage caused by the body’s immune response to the worms. Skin depigmentation can have significant cosmetic implications for affected individuals and may contribute to social stigmatization.
🩺 Diagnosis
Diagnosis of 1F6A.1, also known as Onchocerciasis of the Skin, typically involves a combination of clinical evaluation, imaging tests, and laboratory techniques.
Clinical evaluation may include a physical examination to look for characteristic skin changes associated with onchocerciasis, such as nodules, depigmented patches, or thickened and darkened skin. In some cases, a physician may also inquire about symptoms such as itching, rash, or vision problems that can occur with the disease.
Imaging tests, such as ultrasound or MRI, may be used to visualize the presence of onchocerca worms beneath the skin or in subcutaneous tissues. These tests can help confirm the diagnosis and assess the extent of the infection, especially in cases where nodules or lesions are not easily visible.
Laboratory techniques, including skin snips or blood tests, may be performed to detect the presence of microfilariae in the skin or circulating antibodies against the parasite. These tests can provide definitive evidence of onchocerciasis and help guide treatment decisions. Additional diagnostic tools, such as polymerase chain reaction (PCR) or serologic tests, may also be utilized in certain cases to confirm the diagnosis of 1F6A.1.
💊 Treatment & Recovery
Treatment for Onchocerciasis of the skin (1F6A.1) typically involves the use of anti-parasitic medications, such as ivermectin. This medication helps to kill off the parasitic worms responsible for the infection.
In some cases, antibiotics may also be prescribed to treat secondary infections that may develop as a result of scratching the affected areas. These infections can exacerbate the symptoms of the condition and prolong the recovery process.
Regular monitoring by a healthcare provider is important to ensure that the treatment is effective and to address any potential complications that may arise. It is also recommended to practice good hygiene, avoid scratching the affected areas, and wear protective clothing to prevent further transmission of the disease.
Recovery from Onchocerciasis of the skin depends on early detection and prompt initiation of treatment. In most cases, with proper medical care and adherence to prescribed medications, individuals can experience significant improvement in their symptoms and ultimately achieve full recovery.
Follow-up appointments with a healthcare provider are essential to monitor progress and address any lingering symptoms or complications. In some cases, additional treatment may be necessary to fully eradicate the parasites from the body and prevent future outbreaks of the disease.
🌎 Prevalence & Risk
Onchocerciasis of the skin, coded as 1F6A.1 in the International Classification of Diseases (ICD-10), is a relatively rare parasitic infection caused by the filarial nematode Onchocerca volvulus. The prevalence of onchocerciasis varies by region, with the highest burden found in sub-Saharan Africa where it is endemic. In these regions, mass drug administration programs have been implemented to control the spread of the disease.
In the United States, onchocerciasis is considered rare, with only a few sporadic cases reported each year. Most cases in the U.S. are imported from endemic regions through travel or migration. Due to the low prevalence, onchocerciasis is not considered a major public health concern in the country.
In Europe, onchocerciasis is also rare, with only occasional cases reported in travelers returning from endemic regions. The risk of transmission within Europe is low, as the vector responsible for transmitting Onchocerca volvulus is not present in most European countries. Surveillance and control measures are in place to prevent the introduction and spread of the disease in Europe.
In Asia, onchocerciasis of the skin is extremely rare, with very few documented cases reported in certain countries such as Yemen and Saudi Arabia. The distribution of the disease in Asia is limited to specific localities where the parasite and its vector are present. Due to the low prevalence and limited transmission, onchocerciasis is not a significant public health issue in most Asian countries.
😷 Prevention
Preventing Onchocerciasis of the skin (1F6A.1) involves various measures aimed at controlling the transmission of the disease. One of the key strategies is the mass administration of ivermectin, a medication that kills the larvae of the parasite responsible for the disease. This approach, known as mass drug administration, has been successful in reducing the prevalence of onchocerciasis in many endemic areas.
In addition to mass drug administration, vector control plays a crucial role in preventing onchocerciasis of the skin. The black fly, which transmits the parasite from person to person, breeds in fast-flowing rivers and streams. By implementing measures to control the breeding sites of black flies, such as larviciding or environmental modifications, the transmission of onchocerciasis can be significantly reduced.
Another important aspect of preventing onchocerciasis of the skin is community participation and education. Community members should be educated about the importance of taking ivermectin regularly, as well as ways to protect themselves from black fly bites. Community-based interventions, such as health education campaigns and involvement in treatment programs, can help increase awareness and compliance with preventive measures. By addressing these various components of prevention, efforts to control and ultimately eliminate onchocerciasis of the skin can be more effective.
🦠 Similar Diseases
An analogous code to Onchocerciasis of the skin, 1F6A.1, is 1F6A.2, which refers to Onchocerciasis of the eye. Onchocerciasis, also known as river blindness, is a parasitic disease caused by the worm Onchocerca volvulus. While the skin is a common site of infection, the eyes can also be affected, leading to inflammation, itching, and ultimately blindness if left untreated.
Another pertinent disease code is 1F6A.3, which corresponds to Onchocercal lymphadenitis. This condition involves the inflammation of lymph nodes due to onchocerciasis infection.
