ICD-11 code 1F64 refers to Dracunculiasis, also known as guinea worm disease. This parasitic infection is caused by the roundworm Dracunculus medinensis. It is transmitted through contaminated water sources and affects primarily rural communities in Africa.
Symptoms of Dracunculiasis include fever, swelling, and a painful blister containing the worm. The worm emerges slowly through the skin, causing excruciating pain and disability. This disease has been eradicated from many countries through public health efforts focused on improving water sanitation and implementing preventive measures.
Treatment for Dracunculiasis involves slowly extracting the worm from the blister without breaking it. This process can take weeks or even months to complete. Prevention strategies include filtering drinking water and educating communities about the importance of avoiding contaminated water sources.

#️⃣ Coding Considerations
According to the latest version of the International Classification of Diseases, 11th Revision (ICD-11), the code 1F64 corresponds to Dracunculiasis, a parasitic disease caused by the nematode Dracunculus medinensis. This infection primarily occurs in sub-Saharan Africa and is acquired through drinking water contaminated with copepods carrying the larvae of the nematode. The disease manifests as painful blisters, ulcers, and inflammation in the skin as the female worm emerges from the body. The World Health Organization has been leading efforts to eradicate Dracunculiasis through interventions such as water filtration and education on preventing contamination. By implementing coordinated control measures, affected countries have made significant progress in reducing the incidence of this debilitating 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 1F64 (Dracunculiasis) typically manifest after a one-year incubation period following the ingestion of contaminated water. One of the hallmark symptoms involves the development of a painful blister, usually on the lower extremities, through which the adult female nematode, Dracunculus medinensis, emerges slowly. This blister can cause intense burning pain and may be accompanied by swelling and redness of the surrounding skin.
As the worm emerges from the blister, patients may experience a tingling or burning sensation along the affected area. In some cases, the worm can reach lengths of up to 3 feet, causing further discomfort and pain. As the worm continues to emerge from the blister, the affected individual may experience fever, nausea, vomiting, and dizziness.
Complications of 1F64 (Dracunculiasis) can include secondary bacterial infections at the site of the emerging worm, leading to abscess formation and cellulitis. Additionally, the presence of the worm can hinder mobility and impede the performance of daily tasks for affected individuals. In severe cases, secondary complications such as septicemia or tetanus may arise, further exacerbating the patient’s condition.
🩺 Diagnosis
Diagnosis of Dracunculiasis (1F64) typically involves a combination of clinical symptoms, patient history, and laboratory testing. In areas endemic for Dracunculiasis, patients presenting with symptoms such as blister formation, localized swelling, or skin ulcers may be suspected of having the disease. Additionally, a history of ingesting contaminated water sources, such as ponds or lakes, can help in the diagnosis of Dracunculiasis.
Laboratory testing is essential for confirming a diagnosis of Dracunculiasis. The gold standard diagnostic method is identifying the characteristic larvae of the parasite Dracunculus medinensis in a skin blister or ulcer. This can be done by gently extracting the worm from the lesion and examining it under a microscope. The presence of larvae in the extracted specimen confirms the diagnosis of Dracunculiasis.
In cases where identifying the parasite larvae is challenging, serological tests may be used to detect antibodies against Dracunculus medinensis in the patient’s blood. Enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assays are commonly used serological tests for diagnosing Dracunculiasis. These tests can provide additional diagnostic information in cases where direct visualization of the parasite is not feasible.
💊 Treatment & Recovery
Treatment for Dracunculiasis, also known as Guinea worm disease, focuses on removing the worm from the body. This is typically done by slowly and carefully winding the worm around a piece of gauze or a stick. The process can take several days to weeks, as the worm must be extracted little by little to avoid breaking it.
In addition to physical removal of the worm, patients may also be given medications to help manage symptoms such as pain and inflammation. Antibiotics may be prescribed to prevent secondary bacterial infections. It is important for patients to keep the wound clean and covered to prevent further complications.
Recovery from Dracunculiasis can be a slow process, as the wound where the worm emerged may take weeks to heal. Patients may experience pain, swelling, and itching during this time. It is important for patients to follow their healthcare provider’s instructions for wound care to prevent infection and promote healing. With proper treatment and care, most patients make a full recovery from the disease.
🌎 Prevalence & Risk
In the United States, Dracunculiasis, also known as Guinea worm disease, is no longer considered endemic. The last reported case in the US was in 1993, and the disease has been successfully eradicated through public health interventions and surveillance programs. Despite this, occasional imported cases have been reported among travelers returning from endemic areas.
In Europe, Dracunculiasis is extremely rare and sporadic. Cases are typically imported by travelers returning from endemic countries in Africa and Asia. European countries have implemented strict surveillance measures to prevent the reintroduction and transmission of the disease within their borders. As a result, the risk of local transmission in Europe is considered very low.
In Asia, Dracunculiasis remains endemic in certain countries, particularly in sub-Saharan Africa. The disease is most prevalent in rural communities with limited access to clean water sources. Efforts to eradicate Dracunculiasis in Asia have been ongoing, with significant progress made in reducing the number of cases. However, challenges such as political instability and conflict in some regions continue to hinder eradication efforts.
In Africa, Dracunculiasis is the most prevalent, with the majority of cases reported in sub-Saharan countries. Endemic countries in Africa have made significant strides in eliminating the disease through improved access to clean water sources, health education programs, and increased surveillance efforts. Despite progress, challenges such as conflict, limited resources, and political instability remain obstacles to achieving complete eradication of Dracunculiasis in the region.
😷 Prevention
To prevent Dracunculiasis, also known as Guinea worm disease, it is important to focus on preventing the consumption of contaminated water. This can be achieved by promoting safe drinking water practices, such as filtering or boiling water before consumption. Additionally, educating individuals in endemic regions about the risks associated with drinking untreated water can help prevent the transmission of the disease.
Another important aspect of preventing Dracunculiasis is controlling the populations of copepods, which serve as intermediate hosts for the Guinea worm larvae. This can be done by implementing vector control measures, such as the application of larvicides to water sources where copepods thrive. Furthermore, efforts to improve water sanitation and hygiene practices in endemic areas can help reduce the transmission of Guinea worm disease.
Promoting community-based interventions, such as the distribution of cloth filters for water filtration and the use of protective footwear to prevent contact with contaminated water sources, can also play a key role in preventing Dracunculiasis. By empowering communities to take ownership of their health and implementing sustainable prevention strategies, the incidence of Guinea worm disease can be significantly reduced.
