ICD-11 code 1B21.2Y corresponds to cutaneous infection caused by other specified non-tuberculous mycobacteria. This code specifically indicates the presence of a skin infection resulting from a non-tuberculous mycobacterial organism, which are bacteria that can cause a variety of infections in humans.
Non-tuberculous mycobacteria are a diverse group of bacteria that can be found in soil, water, and various animals. Cutaneous infections caused by these bacteria are rare but can occur through contact with contaminated environments or animals. Such infections typically present as nodules, ulcers, abscesses, or other skin lesions.
The ICD-11 code 1B21.2Y is used by healthcare providers to accurately document and classify cases of cutaneous infections due to non-tuberculous mycobacteria. Proper coding helps in tracking the prevalence of such infections, determining appropriate treatment strategies, and monitoring the effectiveness of control measures.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1B21.2Y is A-A30.5. This code specifically denotes “Cutaneous infection due to non-tuberculous mycobacteria.” SNOMED CT, which stands for Systematized Nomenclature of Medicine–Clinical Terms, is a comprehensive clinical terminology system used internationally for electronic health records and clinical information systems.
By using SNOMED CT, healthcare professionals can accurately document and share clinical information, improving communication and promoting interoperability between different healthcare systems. The code A-A30.5 is essential for coding and classifying cutaneous infections caused by non-tuberculous mycobacteria, allowing for precise diagnosis and treatment. It is important for healthcare providers to be familiar with both ICD-11 and SNOMED CT coding systems to ensure accurate documentation and billing practices.
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 1B21.2Y, also known as cutaneous infection due to other specified non-tuberculous mycobacteria, may vary depending on the individual and the specific type of mycobacteria involved. Common symptoms may include the presence of one or more skin lesions that are often red, raised, and may contain pus. These lesions may also be painful or itchy, leading to discomfort for the affected individual.
In some cases, individuals with cutaneous infection due to non-tuberculous mycobacteria may also experience fever, chills, and malaise. These systemic symptoms are indicative of a more severe infection that may require medical intervention. Additionally, the affected area of the skin may become increasingly inflamed and swollen over time, potentially leading to the formation of abscesses or ulcers.
It is important to note that the symptoms of 1B21.2Y can mimic those of other skin conditions, making accurate diagnosis crucial. If left untreated, cutaneous infections due to non-tuberculous mycobacteria can persist and spread, potentially leading to complications such as cellulitis or sepsis. Therefore, individuals experiencing symptoms suggestive of this condition should seek medical attention promptly for proper evaluation and treatment.
🩺 Diagnosis
Diagnosis methods for 1B21.2Y, or cutaneous infection due to other specified non-tuberculous mycobacteria, typically involve a combination of clinical evaluation, microbiological testing, and imaging studies. The first step in diagnosing this condition is a thorough physical examination by a healthcare provider, who will assess the patient’s skin for signs of infection such as redness, swelling, nodules, or ulcers. The provider may also inquire about the patient’s medical history and any recent travel or exposure to potential sources of mycobacteria.
Microbiological testing is essential for confirming the presence of non-tuberculous mycobacteria in a cutaneous infection. This may involve a skin biopsy, in which a small sample of tissue is collected from the affected area and sent to a laboratory for culture and sensitivity testing. The culture allows for the identification of the specific mycobacterial species causing the infection, while sensitivity testing helps determine the most effective antimicrobial treatment.
In some cases, imaging studies such as X-rays, ultrasound, or MRI may be used to evaluate the extent of tissue involvement and to assess for any underlying bone or joint complications. These imaging modalities can help guide treatment decisions and monitor the response to therapy over time. Additionally, blood tests may be performed to assess the patient’s overall health and immune status, as underlying medical conditions or immunosuppression can increase the risk of mycobacterial infections.
💊 Treatment & Recovery
Treatment for 1B21.2Y, a cutaneous infection due to other specified non-tuberculous mycobacteria, typically involves a multidisciplinary approach. The primary goal of treatment is to eliminate the infection and prevent recurrence. The choice of treatment may vary depending on the specific type of mycobacteria involved, the severity of the infection, and the patient’s overall health status.
In most cases, antibiotic therapy is the mainstay of treatment for cutaneous infections caused by non-tuberculous mycobacteria. The specific antibiotics used will depend on the susceptibility of the infecting organism to various antibiotics. A combination of antibiotics may be necessary to effectively treat the infection and prevent the development of antibiotic resistance.
Surgical intervention may be required in some cases of 1B21.2Y infection, especially if there are large or deep-seated abscesses that are resistant to antibiotic therapy. Surgical drainage of abscesses, debridement of infected tissue, and excision of nodules or ulcers may be necessary to promote healing and prevent the spread of infection. Adjuvant therapies, such as wound care and physical therapy, may also be recommended to support the healing process and prevent complications.
🌎 Prevalence & Risk
In the United States, the prevalence of Cutaneous infection due to other specified non-tuberculous mycobacteria (1B21.2Y) is relatively low compared to other regions. This type of mycobacterial infection is more commonly seen in immunocompromised individuals or those with underlying medical conditions that weaken the immune system. The exact prevalence of 1B21.2Y in the US is difficult to determine due to underreporting and misdiagnosis of such infections.
In Europe, the prevalence of 1B21.2Y is slightly higher than in the United States. This could be attributed to differences in healthcare practices, environmental factors, or genetic predisposition to mycobacterial infections. European countries with higher population densities or higher rates of immunocompromised individuals may see a higher prevalence of Cutaneous infection due to non-tuberculous mycobacteria.
In Asia, the prevalence of 1B21.2Y varies widely among different countries and regions. Some parts of Asia may have a higher prevalence of this type of mycobacterial infection due to factors such as overcrowding, poor sanitation, or limited access to healthcare. Additionally, certain traditional practices or cultural beliefs in Asia may contribute to the transmission of non-tuberculous mycobacteria.
In Africa, like in Asia, the prevalence of Cutaneous infection due to other specified non-tuberculous mycobacteria (1B21.2Y) can vary greatly depending on the country and region. Factors such as climate, healthcare infrastructure, and socioeconomic status can all influence the prevalence of mycobacterial infections in African populations. Limited access to healthcare, inadequate infection control measures, and poor environmental sanitation may contribute to a higher prevalence of 1B21.2Y in certain parts of Africa.
😷 Prevention
To prevent cutaneous infections due to other specified non-tuberculous mycobacteria, it is essential to maintain good hygiene practices. Regularly washing hands with soap and water, especially after handling potentially contaminated objects or coming into contact with contaminated surfaces, can help reduce the risk of infection. Additionally, keeping wounds clean and covered can prevent mycobacteria from entering the body through broken skin.
Another important preventive measure is to avoid direct contact with soil and water that may be contaminated with non-tuberculous mycobacteria. This can include wearing protective gloves when working in the garden or handling soil, as well as avoiding swimming or bathing in potentially contaminated bodies of water. Being cautious when engaging in outdoor activities where exposure to contaminated environments is likely can help reduce the risk of cutaneous infections.
Furthermore, individuals with weakened immune systems should take extra precautions to prevent cutaneous infections due to non-tuberculous mycobacteria. This can include following specific guidelines provided by healthcare professionals, such as avoiding certain activities or environments that may increase the risk of infection. Seeking medical advice if any unusual skin changes or symptoms occur can also help in early detection and treatment of cutaneous infections. Regular check-ups and screenings may be recommended for individuals at higher risk of developing infections due to non-tuberculous mycobacteria.
