ICD-11 code 1F2K refers to talaromycosis, a rare and potentially serious fungal infection caused by the fungus Talaromyces marneffei. This infection primarily affects individuals with weakened immune systems, such as those living with HIV/AIDS or undergoing immunosuppressive therapy. Talaromycosis typically presents with symptoms such as fever, weight loss, skin lesions, and respiratory problems.
The fungus Talaromyces marneffei is commonly found in the environment in Southeast Asia, particularly in areas with high humidity and soil rich in organic matter. Infection with this fungus occurs through inhalation of spores, which can lead to the development of talaromycosis in susceptible individuals. Talaromycosis is predominantly seen in regions such as Thailand, Hong Kong, and other parts of Southeast Asia where the fungus is endemic.
Diagnosis of talaromycosis is typically made through a combination of clinical evaluation, imaging studies, and laboratory tests such as fungal cultures and serological assays. Treatment of talaromycosis involves antifungal medications such as amphotericin B and itraconazole, which are effective in managing the infection and improving outcomes for affected individuals. Early detection and prompt initiation of treatment are crucial in preventing potential complications and improving the prognosis of talaromycosis.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1F2K for Talaromycosis is 399627008. This specific code in the SNOMED Clinical Terms system allows for accurate and standardized data coding for this particular fungal infection. Talaromycosis, caused by the fungus Talaromyces marneffei, primarily affects people with compromised immune systems in endemic regions such as Southeast Asia. By using the appropriate SNOMED CT code, healthcare professionals can effectively document and track cases of Talaromycosis, leading to improved patient care and better surveillance of this potentially life-threatening infection. Furthermore, the use of standardized medical coding systems like SNOMED CT ensures consistency and interoperability in electronic health records, facilitating better communication and data analysis in healthcare settings.
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 1F2K, also known as Talaromycosis, typically begin with flu-like symptoms such as fever, chills, and muscle aches. These initial symptoms are often accompanied by headache, cough, and difficulty breathing. As the infection progresses, patients may develop a persistent cough, chest pain, and fatigue.
In some cases, Talaromycosis can affect the skin, causing lesions or ulcers that do not heal. These skin symptoms may be accompanied by redness, swelling, and tenderness. Patients with Talaromycosis may also experience joint pain, swollen lymph nodes, and weight loss.
In severe cases of Talaromycosis, the infection can spread to other organs such as the liver, spleen, and brain, leading to organ damage and potentially life-threatening complications. It is important for individuals experiencing any of these symptoms to seek medical attention for proper diagnosis and treatment.
🩺 Diagnosis
Diagnosis of 1F2K (Talaromycosis) can be challenging due to its nonspecific symptoms and resemblance to other diseases. The diagnosis is typically made through a combination of clinical evaluation, imaging studies, laboratory tests, and sometimes biopsy.
Clinical evaluation may involve assessing symptoms such as fever, cough, weight loss, and respiratory problems. A thorough physical examination can help identify any abnormalities that may be indicative of Talaromycosis. However, clinical evaluation alone is not enough to confirm the diagnosis.
Imaging studies, such as chest X-rays or CT scans, are often used to evaluate the extent of lung involvement in Talaromycosis. These imaging techniques can show abnormalities such as nodules, cavities, or infiltrates in the lungs that are characteristic of the disease. However, imaging findings are nonspecific and can overlap with other lung conditions.
Laboratory tests play a crucial role in diagnosing Talaromycosis. Blood tests may reveal abnormalities such as anemia, elevated liver enzymes, or low white blood cell counts. Additionally, detection of the Talaromyces marneffei antigen in serum or other body fluids can confirm the diagnosis. In some cases, a biopsy of affected tissues, such as skin lesions or lymph nodes, may be necessary to definitively diagnose Talaromycosis.
💊 Treatment & Recovery
Treatment for 1F2K, also known as Talaromycosis, typically involves antifungal medication. The primary drug of choice is Amphotericin B, administered through intravenous infusion. Alternatives to Amphotericin B include itraconazole, voriconazole, and posaconazole.
In severe cases of Talaromycosis, combination therapy with multiple antifungal agents may be necessary. Treatment duration can vary depending on the severity of the infection and the patient’s response to therapy. Close monitoring of the patient’s condition and regular follow-up visits are essential to assess treatment efficacy and make adjustments as needed.
Recovery from Talaromycosis can be a lengthy process, particularly in cases of disseminated or severe infection. After completing the initial course of antifungal therapy, patients may need to continue on maintenance therapy to prevent recurrence. Regular medical check-ups and monitoring of symptoms are crucial in ensuring successful recovery and preventing potential complications. Supportive care, including adequate nutrition and rest, can also aid in the recovery process.
🌎 Prevalence & Risk
In the United States, cases of 1F2K (Talaromycosis) are relatively rare, with only a small number of reported cases each year. The disease is most commonly found in individuals with compromised immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy. Due to the low prevalence of the disease in the general population, public health efforts focusing on prevention and early detection may be limited.
In Europe, the prevalence of 1F2K (Talaromycosis) is also relatively low compared to regions like Asia and Africa. Cases of the disease are sporadically reported in countries with a higher prevalence of HIV/AIDS and other conditions that weaken the immune system. Limited research and surveillance of the disease in Europe make it difficult to determine the exact burden of 1F2K in the region.
In Asia, 1F2K (Talaromycosis) is more prevalent compared to other regions, particularly in tropical and subtropical areas. The disease is endemic in countries like Thailand, Indonesia, India, and the Philippines, where environmental conditions favor the growth of the causative fungus. Additionally, high rates of HIV/AIDS and other immunocompromising conditions in parts of Asia contribute to the increased prevalence of 1F2K in the region.
In Africa, cases of 1F2K (Talaromycosis) are rare compared to regions like Asia. Limited surveillance and diagnostic capabilities in many African countries may result in underreporting of the disease. However, the disease has been documented in countries with a high prevalence of HIV/AIDS, suggesting that immunosuppression plays a significant role in the burden of 1F2K in Africa. Ongoing research and public health efforts are needed to better understand and address the prevalence of 1F2K in the region.
