ICD-11 code 1F2A.1 refers to a specific diagnosis of histoplasmosis caused by the organism Histoplasma duboisii. This code is used by healthcare providers to accurately document and track cases of this particular fungal infection in patients. Histoplasmosis is a disease caused by inhaling spores of the Histoplasma fungus, which can lead to respiratory symptoms and infections in various organs of the body.
Histoplasmosis due to Histoplasma duboisii is a less common form of the infection compared to the more prevalent Histoplasma capsulatum. However, Histoplasma duboisii is known to cause severe pulmonary and systemic manifestations in individuals who are exposed to the fungus. Patients with histoplasmosis due to Histoplasma duboisii may present with symptoms such as fever, cough, fatigue, and chest pain, which can mimic other respiratory illnesses.
Proper identification and coding of histoplasmosis cases, including those caused by Histoplasma duboisii, are essential for accurate monitoring of disease trends, treatment efficacy, and research purposes. Healthcare professionals rely on ICD-11 codes to effectively communicate and share information about patient diagnoses, enabling better coordination of care and public health efforts.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to ICD-11 code 1F2A.1, which represents Histoplasmosis due to Histoplasma duboisii, is 201859004. This code is used to categorize and classify medical conditions and diseases for health information exchange and clinical documentation. SNOMED CT, or Systematized Nomenclature of Medicine Clinical Terms, is a comprehensive clinical terminology developed for the electronic exchange of health information. It provides a standardized way of representing and sharing health-related information globally. By using SNOMED CT codes, healthcare providers and systems can accurately capture and communicate patient diagnoses, treatments, and outcomes in a consistent and interoperable manner. This helps improve the quality of healthcare delivery, research, and public health reporting.
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
Histoplasmosis due to Histoplasma duboisii (1F2A.1) presents with a variety of symptoms that can affect different parts of the body. The respiratory system is often the primary site of infection, leading to symptoms such as cough, chest pain, and difficulty breathing. Some individuals may also experience fever, chills, and night sweats as the infection progresses.
In severe cases of histoplasmosis due to Histoplasma duboisii, the fungus can spread beyond the respiratory system to other organs. This may result in symptoms such as enlarged lymph nodes, skin lesions, and joint pain. Involvement of the central nervous system can lead to headaches, confusion, and seizures.
The severity and duration of symptoms can vary depending on the individual’s immune system response and the extent of the infection. It is important for individuals experiencing symptoms of histoplasmosis due to Histoplasma duboisii to seek medical attention for proper diagnosis and treatment. Early detection and management of the infection can help prevent complications and improve outcomes for patients.
🩺 Diagnosis
Diagnosis of Histoplasmosis due to Histoplasma duboisii (1F2A.1) primarily relies on a combination of clinical presentation, laboratory testing, and imaging studies. Patients with histoplasmosis often present with nonspecific symptoms such as fever, cough, fatigue, and weight loss. Given the broad range of symptoms, a thorough medical history and physical examination are crucial in suspecting Histoplasma duboisii infection.
Laboratory tests play a critical role in the diagnosis of Histoplasma duboisii infection. The most commonly used diagnostic test is the detection of Histoplasma antigens in blood or urine samples. Serologic testing, such as enzyme immunoassays, can also be used to detect antibodies against Histoplasma duboisii. Additionally, fungal culture of respiratory samples or biopsy specimens may be necessary for definitive diagnosis.
Imaging studies, such as chest x-rays or computed tomography (CT) scans, can help identify characteristic findings associated with Histoplasma duboisii infection. These imaging modalities may reveal pulmonary infiltrates, mediastinal lymphadenopathy, or cavity formation in the lungs. In cases of disseminated disease, imaging studies can also detect involvement of other organs, such as the liver, spleen, or adrenal glands.
In some cases, a histopathological examination of biopsy specimens from affected tissues may be required to confirm the presence of Histoplasma duboisii. Histopathological findings typically include granulomatous inflammation with necrosis and the presence of yeast-like organisms within macrophages. Given the diverse clinical manifestations of Histoplasma duboisii infection, a multidisciplinary approach involving infectious disease specialists, pulmonologists, radiologists, and pathologists is often necessary for accurate diagnosis and treatment.
💊 Treatment & Recovery
Treatment for 1F2A.1, also known as Histoplasmosis due to Histoplasma duboisii, typically involves antifungal medications. The most commonly used antifungal for treating histoplasmosis is itraconazole, which is taken orally for a period of several weeks to months. In more severe cases, Amphotericin B may be used as an alternative treatment.
In addition to antifungal medications, supportive care may be necessary to manage symptoms and complications of histoplasmosis. This may include treatment for respiratory distress, fluid and electrolyte imbalances, and other medical issues that can arise as a result of the infection. Patients with severe cases of histoplasmosis may require hospitalization for closer monitoring and management of their condition.
Recovery from histoplasmosis due to Histoplasma duboisii varies depending on the severity of the infection and the overall health of the individual. In many cases, patients will start to feel better within a few weeks of starting treatment with antifungal medications. However, it is important to complete the full course of prescribed medication to ensure that the infection is fully cleared. Follow-up appointments with healthcare providers may also be necessary to monitor progress and ensure that the infection has been successfully treated.
🌎 Prevalence & Risk
In the United States, Histoplasma duboisii is rarely seen, with only a few cases reported each year. The majority of cases of histoplasmosis in the United States are caused by Histoplasma capsulatum, which is more common in the soil of endemic regions.
In Europe, Histoplasma duboisii is also considered rare, with only sporadic cases reported in various countries. The fungus is more commonly found in tropical and subtropical regions, where it thrives in the soil enriched with bird or bat droppings.
In Asia, Histoplasma duboisii is not commonly seen, and cases are infrequently reported in medical literature. Most cases of histoplasmosis in Asia are caused by Histoplasma capsulatum, which is endemic in certain regions of the continent.
In Africa, Histoplasma duboisii is more prevalent, particularly in West and Central Africa, where the fungus is endemic. Cases of histoplasmosis due to Histoplasma duboisii are more commonly reported in this region compared to other parts of the world.
😷 Prevention
Histoplasmosis due to Histoplasma duboisii, also known as 1F2A.1, is a fungal infection usually acquired by breathing in spores of Histoplasma duboisii. To prevent this infection, individuals should avoid inhaling dust, soil, or bird droppings in areas where the fungus is known to be present.
To reduce the risk of histoplasmosis due to Histoplasma duboisii, individuals should wear protective masks, gloves, and clothing when working in environments where the fungus may be present. It is also recommended to wet down soil before disturbing it and to avoid entering caves, attics, or other areas where the fungus may be found.
In addition to these preventative measures, individuals with weakened immune systems should take extra precautions to avoid exposure to Histoplasma duboisii. This includes avoiding contact with potentially contaminated materials and seeking medical advice if they suspect they may have been exposed to the fungus. By following these guidelines, the risk of contracting 1F2A.1 can be minimized.
