ICD-11 code 1F2A.Y refers to “Other specified histoplasmosis,” which is a specific type of fungal infection caused by the Histoplasma capsulatum fungus. This code is used to categorize cases of histoplasmosis that do not fit into the more commonly classified forms of the disease.
Histoplasmosis is a respiratory infection that is typically acquired through inhalation of spores from contaminated soil or bird droppings. Symptoms of histoplasmosis can vary widely, ranging from mild respiratory symptoms to severe systemic infections involving multiple organs.
The designation of “other specified histoplasmosis” in ICD-11 code 1F2A.Y may be used when the specific type or location of the infection is known but does not fit into one of the more precisely defined categories of the disease. Overall, accurate and detailed coding of histoplasmosis cases is essential for tracking and monitoring the prevalence of this fungal infection.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 1F2A.Y (Other specified histoplasmosis) is 62522000. This SNOMED CT code specifically pertains to “Histoplasmosis, unspecified,” which captures the essence of the broader ICD-11 code. This code allows for precise tracking and analysis of cases of histoplasmosis in healthcare data systems. SNOMED CT, as an international clinical terminology system, enables standardized communication and interoperability across different healthcare organizations and systems. By using SNOMED CT codes in conjunction with ICD-11 codes, healthcare professionals gain access to a wealth of clinical information and facilitate better patient care and research outcomes. The seamless integration of these coding systems ultimately benefits both providers and patients alike in managing and treating histoplasmosis effectively.
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 1F2A.Y (Other specified histoplasmosis) can vary depending on the severity of the infection and the individual’s immune system response. Common symptoms of histoplasmosis include fever, cough, chest pain, and fatigue. In some cases, individuals may experience shortness of breath, weight loss, and night sweats.
As the infection progresses, patients may develop more severe symptoms such as joint pain, blurred vision, and skin rashes. Histoplasmosis can also affect the liver, spleen, and adrenal glands, leading to symptoms like abdominal pain and jaundice. Some individuals may experience central nervous system involvement, resulting in headaches, confusion, and seizures.
In severe cases, histoplasmosis can cause respiratory distress, lung nodules, and granulomas. Disseminated histoplasmosis, which occurs when the infection spreads beyond the lungs, can lead to organ failure and potentially be life-threatening. Prompt medical evaluation and treatment are essential for managing symptoms and preventing complications associated with 1F2A.Y (Other specified histoplasmosis).
🩺 Diagnosis
Diagnosis of 1F2A.Y (Other specified histoplasmosis) may involve a combination of medical history, physical examination, laboratory tests, and imaging studies. Patients with suspected histoplasmosis may present with symptoms such as fever, cough, chest pain, and fatigue. The healthcare provider will inquire about travel history to regions where Histoplasma capsulatum is endemic, as well as occupational or environmental exposures.
Laboratory tests play a crucial role in the diagnosis of histoplasmosis. Blood tests may reveal abnormalities such as elevated inflammatory markers or specific antibodies to Histoplasma capsulatum. A sputum or tissue sample may be obtained and examined for the presence of the fungus. Furthermore, fungal cultures, polymerase chain reaction (PCR) tests, and antigen tests may be performed to confirm the diagnosis.
Imaging studies such as chest X-rays or computed tomography (CT) scans may be ordered to evaluate the extent of lung involvement in patients with suspected histoplasmosis. These imaging tests can help identify characteristic findings such as pulmonary nodules, consolidation, or mediastinal lymphadenopathy. Additionally, other imaging modalities such as ultrasound or magnetic resonance imaging (MRI) may be utilized to assess extrapulmonary manifestations of the infection.
💊 Treatment & Recovery
Treatment for 1F2A.Y (Other specified histoplasmosis) typically involves antifungal medications, such as itraconazole or fluconazole. These medications work to eliminate the Histoplasma fungus from the body by inhibiting its growth and reproduction. Treatment duration may vary depending on the severity of the infection and the individual’s response to medication. In some cases, more aggressive treatments, such as amphotericin B, may be necessary.
In addition to antifungal medications, supportive care may be provided to manage symptoms and complications of histoplasmosis. This may include pain management, supplemental oxygen therapy, or treatment for respiratory issues. In severe cases of disseminated histoplasmosis, hospitalization may be required for close monitoring and more intensive treatment.
Recovery from 1F2A.Y (Other specified histoplasmosis) can vary depending on the individual’s overall health, the severity of the infection, and the promptness of treatment. Most cases of histoplasmosis respond well to antifungal medications, with symptoms typically improving within a few weeks to a few months. However, in some cases, especially in individuals with weakened immune systems, recovery may take longer and require ongoing treatment. Regular follow-up evaluations may be recommended to monitor treatment effectiveness and to address any lingering symptoms or complications.
🌎 Prevalence & Risk
In the United States, the prevalence of 1F2A.Y (Other specified histoplasmosis) is estimated to be relatively low compared to other regions. However, due to variations in reporting and diagnostic practices, the true prevalence may be underestimated. In certain endemic areas of the country, such as the Ohio and Mississippi River valleys, the incidence of histoplasmosis is notably higher.
In Europe, the prevalence of 1F2A.Y is generally lower compared to regions like the Americas. Cases of histoplasmosis in Europe are often attributed to travel to endemic areas or to occupational exposures. The lack of awareness and limited availability of diagnostic testing in some European countries may also contribute to underreporting of cases.
In Asia, the prevalence of 1F2A.Y is not well-documented, but cases have been reported in various countries such as India, China, and Thailand. The true burden of histoplasmosis in Asia may be underestimated due to limited surveillance and diagnostic capabilities in many regions. As the disease is often misdiagnosed or underdiagnosed, accurate prevalence data for histoplasmosis in Asia remains a challenge.
In Africa, little is known about the prevalence of 1F2A.Y (Other specified histoplasmosis). The disease is generally considered rare in most African countries, but cases have been reported in regions with suitable environmental conditions for the fungus to thrive. Given the limited awareness and diagnostic capacity in many African countries, the true burden of histoplasmosis in the region is likely underestimated.
😷 Prevention
Prevention of other specified histoplasmosis (1F2A.Y) involves avoiding exposure to the fungus that causes the disease, Histoplasma capsulatum. This fungus is commonly found in areas with bird or bat droppings, such as caves, bird roosts, and areas with heavy vegetation. Individuals should take precautions when working in or near these environments, such as wearing protective clothing, masks, and gloves to minimize the risk of inhaling the spores of the fungus.
In addition to avoiding high-risk environments, individuals can also take steps to reduce their risk of developing other specified histoplasmosis by practicing good hygiene. This includes regularly washing hands with soap and water, especially after working in areas where the fungus may be present. It is also important to avoid touching the face, especially the eyes, nose, and mouth, as this can introduce the fungus into the body.
For individuals with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, prevention of other specified histoplasmosis may involve taking antifungal medications prophylactically. These medications can help prevent the fungus from causing infection in individuals who are at higher risk of developing severe forms of the disease. Individuals should consult their healthcare provider for guidance on the use of these medications and other preventive measures.
