ICD-11 code 1F6B represents Strongyloidiasis, a parasitic infection caused by the roundworm Strongyloides stercoralis. This condition is predominantly found in tropical and subtropical regions, where poor sanitation and overcrowding contribute to its transmission. Strongyloidiasis can be acquired through skin contact with contaminated soil or water, making it a significant health concern in developing countries.
Symptoms of Strongyloidiasis can vary widely, from mild gastrointestinal discomfort to severe systemic infections in immunocompromised individuals. Chronic infections can lead to malnutrition, weight loss, anemia, and even life-threatening complications such as septicemia. The diagnosis of Strongyloidiasis often relies on a combination of clinical presentation, stool examination for parasites, and specific serological tests to detect antibodies against Strongyloides stercoralis.
Treatment for Strongyloidiasis typically involves anti-parasitic medications such as ivermectin or albendazole, which can effectively eliminate the parasite from the body. However, repeated or prolonged courses of treatment may be necessary to completely eradicate the infection and prevent recurrence. In severe cases of disseminated Strongyloidiasis, additional therapies such as corticosteroids may be required to manage the immune response and reduce organ damage.

#️⃣ Coding Considerations
SNOMED CT code 62421001 corresponds to ICD-11 code 1F6B, which represents the medical condition known as Strongyloidiasis. Strongyloidiasis is a parasitic infection caused by the roundworm Strongyloides stercoralis. This infection is particularly prevalent in tropical and subtropical regions, with transmission typically occurring through contact with contaminated soil or water. Symptoms of Strongyloidiasis can range from mild gastrointestinal issues to more severe complications, such as hyperinfection syndrome and disseminated disease. Diagnosis of Strongyloidiasis is often challenging due to the non-specific nature of symptoms and the need for specialized testing methods. Treatment typically involves the use of anti-parasitic drugs, such as ivermectin or albendazole, with follow-up monitoring to ensure complete eradication of the parasite from the body. Early detection and prompt treatment are crucial in managing Strongyloidiasis and preventing potential complications.
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 Strongyloidiasis, caused by the nematode Strongyloides stercoralis, can range from mild to severe. Infections can lead to gastrointestinal symptoms such as abdominal pain, diarrhea, and bloating. Some individuals may also experience skin manifestations, such as itching and rash, due to larval migration through the skin.
Respiratory symptoms, including cough, wheezing, and shortness of breath, can occur in cases of hyperinfection syndrome. This syndrome, typically seen in immunocompromised individuals, can lead to disseminated strongyloidiasis with potentially life-threatening complications. In severe cases, there may be systemic symptoms such as fever, weight loss, and malaise.
Neurological symptoms, such as meningitis or encephalitis, can also occur in rare cases of disseminated strongyloidiasis. Additionally, eosinophilia may be present in blood tests, though this is not specific to Strongyloidiasis and can occur in a variety of parasitic infections. It is essential for healthcare providers to consider the possibility of Strongyloidiasis in individuals with compatible symptoms, especially those with a history of travel to endemic regions or risk factors for infection.
🩺 Diagnosis
Diagnosis of 1F6B (Strongyloidiasis) typically involves several methods to confirm the presence of the parasite in the body. One common approach is through stool examinations, where samples are collected and analyzed for the presence of Strongyloides larvae. Multiple stool samples may be required over a period of days to increase the chances of detecting the parasite.
In cases where stool examinations may not yield definitive results, serologic tests can be conducted to detect specific antibodies against Strongyloides. These blood tests can help confirm the presence of the infection, especially in individuals with chronic or disseminated strongyloidiasis. Serologic testing is generally more sensitive than stool examinations, but may not always be conclusive on its own.
In some instances, imaging studies such as chest X-rays or CT scans may be necessary to detect complications associated with strongyloidiasis, such as intestinal blockages or pulmonary involvement. These studies can provide valuable information on the extent of the infection and help guide treatment decisions. Additionally, biopsies of affected tissues may be performed to directly visualize the presence of Strongyloides larvae. These methods collectively contribute to a more accurate diagnosis of 1F6B (Strongyloidiasis).
💊 Treatment & Recovery
Treatment for Strongyloidiasis, caused by the parasitic nematode Strongyloides stercoralis, involves the use of anthelminthic medications such as ivermectin or albendazole. These drugs work by killing the adult worms and larvae in the body, leading to a reduction in the number of parasites. Treatment duration typically ranges from one to three days, depending on the severity of the infection and the individual’s overall health.
In cases of disseminated strongyloidiasis or hyperinfection syndrome, where the parasite has spread to other organs and tissues or there is a high parasite burden, more aggressive treatment with higher doses of anthelminthic medications may be necessary. Patients with severe symptoms may also require supportive measures such as corticosteroids to manage inflammation and antibiotics to prevent secondary bacterial infections.
After completing the initial course of treatment, patients with strongyloidiasis should undergo repeat stool examinations to confirm the eradication of the parasite. Follow-up testing is crucial to ensure that no residual worms or larvae remain in the body, as untreated or inadequately treated infections can lead to chronic complications or re-infection. Education on proper hygiene practices, including handwashing and proper disposal of feces, is also essential in preventing the transmission of Strongyloides stercoralis and reducing the risk of future infections.
🌎 Prevalence & Risk
In the United States, Strongyloidiasis is considered to be a rare infection with a prevalence that is difficult to determine due to underreporting and lack of surveillance. Cases of Strongyloidiasis are usually seen among immigrants from endemic regions and individuals who have traveled to such areas. The actual prevalence in the United States remains largely unknown.
In Europe, Strongyloidiasis is also considered to be a rare infection, with most cases being reported among immigrants from endemic regions or travelers returning from these areas. The prevalence of Strongyloidiasis in Europe is thought to be low, but accurate data is limited due to lack of surveillance and underreporting. Endemic areas in Europe include southeastern countries such as Greece and Italy where the infection has been sporadically reported.
In Asia, Strongyloidiasis is more prevalent compared to the United States and Europe, with certain regions being considered endemic for the infection. Countries in Southeast Asia, such as Thailand, Vietnam, and Cambodia, have higher rates of Strongyloidiasis due to favorable environmental conditions for the parasite. The prevalence of Strongyloidiasis in Asia is likely underestimated due to limited resources for tracking and reporting cases.
In Africa, the prevalence of Strongyloidiasis is generally higher compared to other regions, with some countries in sub-Saharan Africa endemic for the infection. Poor sanitation and lack of access to healthcare contribute to the spread of Strongyloidiasis in these areas. The true prevalence of Strongyloidiasis in Africa is likely higher than reported figures due to challenges in surveillance and accurate diagnosis.
😷 Prevention
Strongyloidiasis is a parasitic infection caused by the nematode Strongyloides stercoralis. There are several strategies to prevent the spread of 1F6B, including improving sanitation, hygiene, and water quality. Proper disposal of human waste and avoiding contact with contaminated soil can help reduce the risk of infection.
One key preventive measure is to wear proper footwear in areas where the parasite is endemic. This can help prevent skin penetration by the larvae of Strongyloides stercoralis. Additionally, individuals should avoid walking barefoot in areas with poor sanitation or where human waste is present.
Public health education plays a crucial role in preventing the transmission of 1F6B. Health authorities should provide information on the risks of Strongyloidiasis and promote the adoption of good hygiene practices. This includes encouraging regular handwashing, especially before handling food, and teaching proper waste disposal methods to reduce environmental contamination.
🦠 Similar Diseases
Strongyloidiasis (ICD-10 code: B78.3) is a parasitic infection caused by the nematode Strongyloides stercoralis. This disease is characterized by a variety of symptoms, including gastrointestinal issues, respiratory problems, and skin irritation.
One disease similar to strongyloidiasis is Ascariasis (ICD-10 code: B77), caused by the roundworm Ascaris lumbricoides. Ascariasis can also lead to gastrointestinal symptoms, respiratory complications, and occasionally skin manifestations, making it akin to strongyloidiasis in its presentation.
Another disease that shares similarities with strongyloidiasis is Hookworm infection (ICD-10 code: B76). This parasitic disease, caused by hookworm species such as Ancylostoma duodenale and Necator americanus, can result in similar gastrointestinal symptoms, anemia, and skin irritation. Like strongyloidiasis, hookworm infection can have chronic manifestations if left untreated.
Scabies (ICD-10 code: B86), a skin infestation caused by the mite Sarcoptes scabiei, also presents with skin irritation and itching, much like strongyloidiasis. While scabies primarily affects the skin, it can lead to secondary infections if not managed properly, just as complications can arise from untreated strongyloidiasis.
