ICD-11 code 1B21.2 pertains to cutaneous non-tuberculous mycobacterial infection, which is a specific type of infection caused by mycobacteria other than those that cause tuberculosis. This code is used in the International Classification of Diseases (ICD) system to classify and track cases of this particular type of infection in medical records and healthcare databases.
Cutaneous non-tuberculous mycobacterial infection typically presents as localized skin lesions that can be red, swollen, and sometimes ulcerated. These infections are typically acquired through exposure to contaminated water or soil, but they can also occur through other means such as trauma or surgery. The diagnosis of this condition can be challenging and often requires special laboratory tests to identify the specific mycobacterial species responsible for the infection.
Treatment for cutaneous non-tuberculous mycobacterial infection usually involves a combination of antibiotics that are specifically effective against the mycobacterial species causing the infection. In some cases, surgical intervention may be necessary to remove infected tissue or to drain abscesses that may form. Proper diagnosis and management of this type of infection are important to prevent complications and to ensure a successful treatment outcome for affected individuals.

#️⃣ Coding Considerations
The equivalent SNOMED CT code for the ICD-11 code 1B21.2 (Cutaneous non-tuberculous mycobacterial infection) is 51202002. This SNOMED CT code represents the specific diagnosis of a cutaneous infection caused by non-tuberculous mycobacteria, which are a group of bacteria commonly found in the environment. The code 51202002 is used to classify and track cases of this type of infection in electronic health records and medical databases. Healthcare providers and researchers rely on accurate coding to properly document and study the prevalence and treatment of cutaneous non-tuberculous mycobacterial infections. By using standardized codes like 51202002, healthcare professionals can communicate effectively and ensure consistent classification of diseases across different 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
Cutaneous non-tuberculous mycobacterial (NTM) infections caused by organisms such as Mycobacterium avium complex, M. marinum, and M. chelonae are characterized by diverse clinical presentations. The symptoms of 1B21.2 manifest predominantly on the skin, presenting as nodules, abscesses, ulcers, or cellulitis. These lesions may exhibit variable degrees of inflammation, erythema, and tenderness upon palpation.
The course of the infection can be acute or chronic, depending on the pathogen involved. In some cases, the lesions may be localized to a specific area of the skin, while in others, they may spread to contiguous or distant sites. Patients with cutaneous NTM infections may experience fever, malaise, and lymphadenopathy, suggesting systemic involvement of the disease.
Diagnosis of 1B21.2 is typically confirmed through clinical assessment, microbiological culture, and histopathological examination of tissue samples. The lesions can be biopsied for culture and stained with acid-fast bacilli to detect mycobacterial presence. Polymerase chain reaction (PCR) testing may also be utilized to identify the specific species of NTM responsible for the infection.
Treatment of cutaneous NTM infections involves a multidisciplinary approach, including antimicrobial therapy, surgical debridement, and wound care. Antibiotics such as macrolides, quinolones, and tetracyclines are commonly prescribed to eradicate the mycobacterial organisms. In cases of severe or refractory infection, consultation with infectious disease specialists may be warranted to optimize therapeutic management and prevent disease progression.
🩺 Diagnosis
Diagnosis of 1B21.2, also known as cutaneous non-tuberculous mycobacterial infection, can be challenging due to its nonspecific clinical presentation. In order to accurately diagnose this condition, a thorough medical history and physical examination are important initial steps. The presence of risk factors such as recent trauma, surgery, or immunosuppression may also aid in the diagnostic process.
Laboratory testing plays a crucial role in confirming the diagnosis of cutaneous non-tuberculous mycobacterial infection. Culturing the organism from a skin biopsy or tissue sample is considered the gold standard for diagnosis. Additionally, polymerase chain reaction (PCR) testing can be used to detect the presence of mycobacterial DNA in skin samples, providing a rapid and sensitive diagnostic tool.
Histopathological examination of skin biopsy specimens may also be useful in diagnosing 1B21.2. Microscopic evaluation of tissue samples can reveal characteristic findings such as granulomatous inflammation and acid-fast bacilli, which are indicative of mycobacterial infection. These pathological changes, in conjunction with clinical and laboratory findings, can help confirm the diagnosis of cutaneous non-tuberculous mycobacterial infection.
💊 Treatment & Recovery
Treatment of 1B21.2 (Cutaneous non-tuberculous mycobacterial infection) typically involves a combination of antimicrobial therapy and surgical intervention. Antimicrobial therapy may consist of antibiotics such as clarithromycin, rifampin, or ethambutol, depending on the specific organisms identified through culture and sensitivity testing.
Surgical intervention may be necessary to remove infected tissue or drain abscesses. This can help reduce the bacterial burden and improve the effectiveness of antimicrobial therapy. In some cases, skin grafts may be required to promote wound healing and prevent recurrence of the infection.
Recovery from cutaneous non-tuberculous mycobacterial infection can be prolonged and may require long-term antimicrobial therapy. Patients should be monitored closely for signs of infection recurrence or resistance to treatment. It is important for patients to adhere to their prescribed treatment regimen and follow up with their healthcare provider regularly to ensure optimal outcomes.
🌎 Prevalence & Risk
In the United States, cutaneous non-tuberculous mycobacterial infections are relatively rare compared to other types of skin infections. However, the prevalence of 1B21.2 in the United States has been increasing in recent years due to various factors such as an aging population, increasing rates of immunosuppression and antibiotic resistance. The exact prevalence rate of this condition in the United States is not well-established due to under-reporting and misdiagnosis.
In Europe, cutaneous non-tuberculous mycobacterial infections are more commonly seen in certain regions with specific environmental conditions such as warm and humid climates. The prevalence of 1B21.2 in Europe varies from country to country, with higher rates reported in southern countries like Spain and Italy. However, overall prevalence data for Europe as a whole is lacking due to limited surveillance and reporting systems in place.
In Asian countries, cutaneous non-tuberculous mycobacterial infections are more prevalent compared to Western countries.
