ICD-11 code 1F25 is used to classify coccidioidomycosis, a fungal infection also known as Valley fever. This disease is caused by inhaling spores of the fungus Coccidioides, which is commonly found in the soil of endemic areas such as the Southwestern United States and parts of Mexico and Central and South America.
Coccidioidomycosis can have a range of symptoms, from flu-like symptoms to severe pneumonia or meningitis. In some cases, the infection may resolve on its own, while in others, it may require antifungal medication or other treatments. The severity of the illness can vary depending on the individual’s immune system and other factors.
Diagnosis of coccidioidomycosis is typically based on symptoms, physical exam findings, and laboratory tests such as blood tests or imaging studies. Treatment may include antifungal medications, rest, and supportive care. It is important for healthcare providers to be aware of this condition, especially in patients who live in or have traveled to endemic areas.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 1F25, which corresponds to Coccidioidomycosis, a fungal infection caused by inhaling the spores of the Coccidioides fungus present in soil, is 59817005. This SNOMED CT code specifically refers to the condition known as Coccidioidomycosis, also referred to as Valley fever, which primarily affects the lungs but can also spread to other parts of the body. Coccidioidomycosis is most commonly found in arid regions of the southwestern United States, Mexico, and Central and South America, with symptoms ranging from flu-like manifestations to severe, potentially fatal complications in immunocompromised individuals. The adoption of standardized coding systems like SNOMED CT and ICD-11 allows for consistent and accurate documentation of diseases, enabling healthcare providers worldwide to communicate effectively and ensure patients receive the appropriate care.
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 Coccidioidomycosis, also known as Valley fever, vary widely from person to person. The majority of people infected with the fungus Coccidioides never exhibit any symptoms and thus never seek medical attention. For those who do exhibit symptoms, they typically appear one to three weeks after exposure to the fungus. Common symptoms may include fever, cough, chest pain, chills, night sweats, fatigue, or a rash.
In some cases, symptoms of coccidioidomycosis may resemble those of pneumonia or the flu. These may include shortness of breath, coughing up blood, joint pain, headaches, muscle aches, weight loss, or swollen lymph nodes. More severe cases of the disease can lead to the development of chronic pneumonia, lung nodules (known as coccidioidal nodules), or disseminated disease, in which the fungus spreads beyond the lungs to other parts of the body, such as the skin, bones, joints, or brain.
Disseminated coccidioidomycosis can result in a variety of symptoms depending on where the infection has spread. Skin lesions, bone pain, meningitis (inflammation of the membranes surrounding the brain and spinal cord), and joint swelling are all possible manifestations of the disease. In very rare cases, disseminated coccidioidomycosis can be fatal if not promptly treated with antifungal medication. It is important for individuals who suspect they have symptoms of coccidioidomycosis to seek medical attention for proper diagnosis and treatment.
🩺 Diagnosis
Diagnosis of 1F25 (Coccidioidomycosis) involves several methods to confirm the presence of the fungal infection. One primary method is through the collection of respiratory specimens, including sputum, bronchoalveolar lavage fluid, or tissue samples from lung biopsies. These specimens are then subjected to various laboratory tests to detect the presence of Coccidioides spp.
One of the most common diagnostic tests for 1F25 is the Coccidioides antigen test, which detects specific antigens produced by the fungus in the patient’s blood, cerebrospinal fluid, or other body fluids. This test helps in confirming the diagnosis of Coccidioidomycosis and monitoring the progress of the infection. Additionally, serological tests such as immunodiffusion, complement fixation, and enzyme immunoassays are also performed to detect antibodies against Coccidioides spp. in the patient’s blood.
Imaging studies, such as chest X-rays and CT scans, may also be used in the diagnosis of 1F25 to detect lung abnormalities, such as nodules, cavities, or pleural effusions, which are characteristic of Coccidioidomycosis. These imaging studies help in evaluating the extent of the infection and monitoring the response to treatment. In some cases, a biopsy of affected tissues may be recommended to confirm the presence of Coccidioides spp. and rule out other potential causes of respiratory symptoms.
💊 Treatment & Recovery
Treatment for coccidioidomycosis typically involves antifungal medications, such as fluconazole, itraconazole, or amphotericin B. The specific drug and duration of treatment depend on the severity of the infection and the patient’s overall health. In some cases, combination therapy may be used to increase effectiveness and reduce the risk of drug resistance.
In addition to antifungal medication, supportive care may be necessary for managing symptoms and complications of coccidioidomycosis. This can include rest, hydration, and pain management. For severe cases, hospitalization may be required for monitoring and more aggressive treatment.
Recovery from coccidioidomycosis can vary depending on the individual’s immune response and the extent of the infection. Some patients may recover fully with appropriate treatment, while others may experience chronic or recurrent symptoms. Follow-up care, including regular monitoring for relapse, may be necessary to ensure a successful recovery. Education about prevention methods, such as avoiding dust exposure in endemic areas, is also important in reducing the risk of reinfection.
🌎 Prevalence & Risk
In the United States, 1F25, more commonly known as coccidioidomycosis, is primarily found in the southwestern regions of the country, including California, Arizona, and Texas. The Centers for Disease Control and Prevention (CDC) reports that there are approximately 10,000 cases of coccidioidomycosis diagnosed in the U.S. each year. The exact prevalence of 1F25 varies by state, with Arizona having the highest number of reported cases.
In Europe, 1F25 is relatively rare compared to other fungal infections. The disease is most commonly observed in individuals who have traveled to endemic areas such as the southwestern United States or other regions with a high concentration of coccidioides fungi. Cases of coccidioidomycosis in Europe are often diagnosed in individuals who have returned from trips to endemic regions, rather than occurring naturally within European populations.
In Asia, coccidioidomycosis is also considered rare, with the disease being most commonly reported in individuals who have traveled to endemic regions in the United States or Latin America. The prevalence of 1F25 in Asia is not well-documented, but cases have been reported in individuals who have had prolonged exposure to coccidioides fungi in endemic areas. Due to differences in climate and environmental conditions, the occurrence of coccidioidomycosis in Asia is generally lower compared to regions where the fungi are more prevalent.
In Africa, instances of 1F25, or coccidioidomycosis, are extremely rare. The disease is primarily endemic to the Americas, with a significant concentration of cases reported in the southwestern United States and parts of Central and South America. Due to the specific environmental requirements for coccidioides fungi to grow and thrive, cases of coccidioidomycosis in Africa are virtually non-existent. Travel-related cases may occur in individuals who have visited endemic regions, but indigenous cases within African populations are extremely uncommon.
😷 Prevention
To prevent 1F25 (Coccidioidomycosis), individuals living in or traveling to endemic areas should take precautions to minimize their risk of exposure to fungal spores. One key measure is to avoid activities that disturb the soil, such as gardening or construction work, which can release spores into the air. It is also advisable to stay indoors during dust storms or windy conditions, as these can lead to increased levels of airborne spores.
Additionally, wearing a mask when working outdoors in endemic areas, particularly during dusty conditions, can help reduce the likelihood of inhaling fungal spores. It is also recommended to keep windows and doors closed during windy weather to prevent spores from entering indoor spaces. Those with weakened immune systems or underlying health conditions should consult with a healthcare provider before traveling to endemic regions to discuss additional precautions that may be necessary.
Furthermore, individuals can reduce their risk of 1F25 by staying informed about the prevalence of Coccidioides in the area they live in or plan to visit. They should be aware of any outbreak alerts or public health notices issued by local authorities and follow any recommended guidelines for protection against exposure to fungal spores. By staying informed and taking appropriate precautions, individuals can help lower their risk of contracting Coccidioidomycosis.
