ICD-11 code 1G02 refers to external hirudiniasis, a medical term used to describe the infestation of the skin with leeches. Leeches are blood-sucking parasites that can attach themselves to humans while swimming or wading in water.
External hirudiniasis can lead to symptoms such as localized itching, rash, and sometimes bleeding at the site of attachment. Leeches secrete a natural anticoagulant called hirudin, which prevents blood from clotting, allowing them to feed more easily.
Treatment for external hirudiniasis typically involves removing the leeches from the skin, disinfecting the affected area, and monitoring for any signs of infection. In some cases, antibiotics may be prescribed to prevent secondary infections.

#️⃣ Coding Considerations
In the realm of medical coding, the SNOMED CT code equivalent to the ICD-11 code 1G02 (External hirudiniasis) is 75873003. This particular code refers to the infestation of leeches on the external parts of the body, which can lead to inflammation and discomfort for the affected individual. SNOMED CT codes are used for more detailed and granular descriptions of medical conditions compared to ICD codes, which are primarily used for billing and administrative purposes. By using the SNOMED CT code 75873003 for External hirudiniasis, healthcare professionals can accurately document and track this specific condition in electronic health records. This streamlined system of medical coding ensures that patients receive proper treatment and care, while also facilitating research and data analysis in the healthcare industry.
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
The primary symptom of 1G02 (External hirudiniasis) is the presence of leeches attached to the skin. These blood-sucking parasites are commonly found in freshwater environments and can attach themselves to human hosts while swimming or wading in infested waters. Leech bites typically leave small, round wounds on the skin that may bleed and become itchy or swollen.
In addition to the physical presence of leeches on the skin, individuals with external hirudiniasis may experience symptoms such as localized pain or discomfort at the site of the leech bite. The saliva of leeches contains anticoagulant compounds that prevent blood from clotting, allowing the parasite to feed on its host’s blood for an extended period of time. This can lead to prolonged bleeding and irritation at the site of attachment.
In some cases, individuals with external hirudiniasis may also develop allergic reactions to leech saliva. Symptoms of an allergic reaction may include redness, swelling, and itching at the site of the leech bite, as well as more severe reactions such as hives, difficulty breathing, or anaphylaxis. It is important for individuals with known allergies to leeches or other parasites to seek medical attention if they suspect they have been bitten by a leech.
🩺 Diagnosis
Diagnosis methods for 1G02, External hirudiniasis, typically involve a thorough physical examination of the affected area. This may include visually inspecting the skin for any evidence of leech attachment or bite marks. Additionally, clinicians may inquire about recent exposure to freshwater bodies where leeches are commonly found.
In some cases, diagnostic tests such as blood tests may be conducted to rule out any systemic infections that could potentially be transmitted by leech bites. If a leech is found attached to the skin, it may be carefully removed and preserved for further identification.
Histopathological examination of skin lesions caused by leech bites may also provide valuable insights into the diagnosis of External hirudiniasis. This can help confirm the presence of leech saliva components in the affected tissues and aid in the definitive diagnosis of the condition.
💊 Treatment & Recovery
Treatment and recovery methods for 1G02, also known as External hirudiniasis, typically involve the removal of the leeches from the affected area. This can be done manually by gently pulling the leech off the skin or by using salt or other irritants to encourage the leech to detach. In some cases, medical professionals may need to intervene to remove the leech safely and effectively.
After the leeches have been removed, it is important to clean the affected area thoroughly to prevent infection. Antibiotic ointments or creams may be prescribed to reduce the risk of infection and promote healing. It is also advisable to keep the affected area clean and dry to facilitate the healing process.
In severe cases of External hirudiniasis, where multiple leech bites have occurred or complications have arisen, hospitalization may be necessary. In such instances, intravenous antibiotics or other medications may be administered to address any systemic infections or other complications. Close monitoring and follow-up care may also be required to ensure a full and speedy recovery for the patient.
🌎 Prevalence & Risk
In the United States, external hirudiniasis, also known as leech infestation, is a relatively rare occurrence. It is typically seen in individuals who engage in outdoor activities such as swimming, fishing, or hiking in freshwater environments where leeches are present. Cases of external hirudiniasis are more commonly reported in states with a higher prevalence of freshwater bodies.
In Europe, the prevalence of external hirudiniasis varies by region. Leech infestations are more commonly reported in countries with abundant freshwater habitats, such as the UK, Germany, and France. Outdoor enthusiasts and individuals involved in recreational water activities are at a higher risk of encountering leeches and developing external hirudiniasis.
In Asia, external hirudiniasis is more prevalent compared to Western countries. Countries with tropical climates and dense forested areas, such as Malaysia, Vietnam, and Indonesia, have a higher incidence of leech infestations. Local populations and travelers exploring rural or jungle environments are more likely to come into contact with leeches and experience external hirudiniasis.
In Africa, external hirudiniasis is also common in regions with tropical climates and abundant freshwater sources. Countries with extensive rainforests, such as the Congo Basin and the Amazon Rainforest, have a higher prevalence of leech infestations. Indigenous populations and travelers venturing into these remote areas are at a higher risk of encountering leeches and developing external hirudiniasis.
😷 Prevention
To prevent 1G02 (External hirudiniasis), it is essential to take measures to avoid exposure to leeches. When engaging in outdoor activities in areas where leeches are prevalent, such as freshwater bodies or muddy terrain, wearing protective clothing can help prevent leech attachment. This includes wearing long sleeves and pants, as well as tucking pant legs into socks or boots to minimize skin exposure.
Furthermore, applying insect repellent containing DEET to exposed skin can act as a deterrent for leeches. It is important to reapply repellent as directed, especially after swimming or sweating. Additionally, regularly inspecting your body and clothing for leeches can aid in early detection and removal, reducing the risk of external hirudiniasis.
In areas where leeches are known to be prevalent, avoiding wading, swimming, or standing in stagnant water can help prevent leech attachment. Leeches are often found in bodies of water with low flow or in moist, shaded areas, so being cautious in these environments can reduce the risk of contracting external hirudiniasis. Taking these preventative measures can help individuals minimize their risk of encountering leeches and developing 1G02.
🦠 Similar Diseases
One disease similar to 1G02 (External hirudiniasis) is 1G04 (Internal hirudiniasis). Internal hirudiniasis occurs when leeches are ingested and attach themselves internally, leading to symptoms such as abdominal pain, vomiting, and bloody stools. This condition is coded similarly to external hirudiniasis due to the presence of leech infestation, but the location of the leeches within the body distinguishes the two diseases.
Another related disease is B88.1 (Leishmaniasis). Leishmaniasis is a parasitic disease caused by protozoa of the genus Leishmania and transmitted by the bite of a sandfly. While the etiology of leishmaniasis differs from hirudiniasis, both conditions involve parasitic infestation which can cause skin lesions and inflammation. The distinction lies in the specific parasite involved and the mode of transmission.
Furthermore, a condition akin to external hirudiniasis is B85.2 (Pediculosis due to Pediculus humanus corporis [body louse]), which refers to infestation with body lice. Like hirudiniasis, pediculosis can lead to itching, skin irritation, and the presence of visible parasites on the skin. Both conditions require proper identification and treatment to eliminate the infestation and alleviate symptoms.
