ICD-11 code 1G05 corresponds to Tungiasis, a parasitic skin infection caused by the female sand flea Tunga penetrans. This condition primarily affects individuals in tropical and subtropical regions, where the sand flea is prevalent. Tungiasis is characterized by the presence of a small, red-brown lesion on the skin, which can cause itching, pain, and inflammation.
The female sand flea burrows into the skin, typically in areas such as the feet, toes, and hands, to lay eggs. This can lead to the formation of a distinct, black-colored “jigger” or “chigoe” embedded in the skin. If left untreated, Tungiasis can result in secondary bacterial infections, abscess formation, and ulceration.
Treatment for Tungiasis involves removing the embedded sand flea through surgical extraction or application of topical medications. Proper hygiene practices, such as keeping the skin clean and dry, can help prevent Tungiasis. In severe cases, where secondary infections have occurred, antibiotics may be necessary to treat the condition effectively.

#️⃣ Coding Considerations
The SNOMED CT code for ICD-11 code 1G05, which corresponds to Tungiasis, is 35005001. Tungiasis is a parasitic skin disease caused by the female sand flea Tunga penetrans, commonly found in tropical and subtropical regions. The SNOMED CT code provides a standardized way to classify and document this specific condition in electronic health records. Health care professionals can use this code to accurately identify and treat cases of Tungiasis, streamlining communication and ensuring proper documentation of the disease. By using the SNOMED CT code 35005001 for Tungiasis, healthcare providers can contribute to improved data exchange and interoperability across different healthcare systems, ultimately benefiting 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 Tungiasis (1G05) typically include intense itching, redness, and swelling at the site of penetration by the sand flea. The affected area may become painful and tender to the touch as the flea continues to burrow into the skin. A small, white papule may eventually form at the site of the penetration.
As the infestation progresses, the papule may develop into a larger lesion with a black dot at its center, indicating the presence of the sand flea. This lesion may be accompanied by the formation of a blister filled with fluid, which can be painful and may become infected if not properly treated. In severe cases, multiple lesions may develop on different parts of the body, leading to significant discomfort and distress for the affected individual.
In addition to the physical symptoms, individuals with tungiasis may also experience psychological distress due to the presence of the parasites in their skin. This can manifest as anxiety, depression, and social isolation, particularly if the infestation is visible or causes significant pain and discomfort. Proper diagnosis and treatment of tungiasis are essential to alleviate symptoms and prevent complications associated with the condition.
🩺 Diagnosis
Diagnosis of tungiasis can typically be made based on clinical presentation and physical examination findings. The presence of a black dot at the site of penetration by the sand flea is a hallmark sign of infection. In addition, symptoms such as itching, pain, and inflammation at the site of penetration may also aid in diagnosis.
Laboratory tests may be performed to confirm the diagnosis of tungiasis, particularly in cases where clinical presentation is unclear. Microscopic examination of skin scrapings from the affected area can help identify the presence of the flea. In some cases, histopathological examination of skin biopsies may also be necessary to confirm the diagnosis.
Imaging studies such as ultrasound may be used to assess the extent of tissue involvement and to detect any complications related to tungiasis. For example, ultrasound can help identify the presence of inflammatory reactions, abscess formation, or secondary infections. These imaging studies can provide valuable information for guiding treatment decisions and monitoring the progress of the infection.
💊 Treatment & Recovery
Treatment for tungiasis mainly involves the removal of the embedded sand flea from the skin. Various methods can be used to achieve this, including surgical extraction, cryotherapy, application of adhesive tape, or the use of a sterile needle to pierce the skin and extract the flea. In some cases, antibiotics may be prescribed to prevent infection of the wound post-extraction.
Surgical extraction is often the most effective method of removing the embedded sand flea, especially for cases where the flea has tunneled deep into the skin. This procedure is typically performed under local anesthesia to minimize pain and discomfort for the patient. The use of sterile instruments and proper wound care post-extraction are crucial to prevent secondary infections.
Cryotherapy, which involves freezing the lesion with liquid nitrogen to destroy the flea, is another treatment option for tungiasis. This method is quick, minimally invasive, and can be performed in an outpatient setting. However, cryotherapy may not be as effective for cases where the flea has burrowed deep into the skin or when multiple lesions are present. Adhesive tape can also be used to suffocate the flea by covering the lesion tightly and leaving it in place for a few hours before removing it.
🌎 Prevalence & Risk
In the United States, tungiasis is considered extremely rare, with only sporadic cases reported in travelers returning from endemic areas. Due to the limited presence of the sand flea vector in the country, the risk of contracting tungiasis within the US is low. However, cases of imported tungiasis have been documented in individuals who have traveled to endemic regions.
In Europe, tungiasis is also uncommon, with few cases reported each year. The risk of contracting the disease is generally low, as the sand flea vector responsible for transmitting tungiasis is not commonly found in European countries. Most cases of tungiasis in Europe are imported by travelers returning from endemic areas, such as parts of Africa, the Caribbean, and South America.
In Asia, tungiasis is more prevalent in certain regions where the sand flea vector is endemic. Countries such as India, Nigeria, and Cameroon have reported a higher incidence of tungiasis cases compared to other Asian countries. In these areas, individuals living in impoverished communities and lacking access to adequate housing and sanitation are at greater risk of contracting tungiasis.
In Africa, tungiasis is considered a significant public health concern, particularly in countries where the sand flea vector is endemic. The disease is prevalent in rural areas with poor living conditions, where individuals are more likely to come into contact with contaminated soil. Tungiasis is endemic in many sub-Saharan African countries, with high rates of infection reported in regions such as Uganda, Tanzania, and Kenya.
😷 Prevention
To prevent Tungiasis (1G05), also known as sand flea infestation, individuals can take several precautionary measures. The primary method of prevention is to avoid walking barefoot in sandy or infested areas where sand fleas are prevalent. Wearing protective footwear, such as closed shoes or sandals, can significantly reduce the risk of Tungiasis infection. Additionally, using insect repellents containing DEET or wearing clothing that covers the feet and legs can further prevent sand flea infestation.
Furthermore, practicing good hygiene and regularly washing and inspecting the feet can help detect and remove any sand fleas before they embed into the skin. Removing any signs of sand fleas as soon as possible can prevent the development of Tungiasis-related symptoms. In cases where individuals are at risk of Tungiasis due to environmental exposure, applying a thin layer of petroleum jelly or insect repellent around the feet and ankles can act as a barrier against sand fleas. These preventive measures can help reduce the incidence of Tungiasis and minimize the discomfort associated with this parasitic infection.
