ICD-11 code 1B21.20 refers to a diagnosis of Mycobacterium ulcerans infection. This code is used in the International Classification of Diseases to define cases where individuals have been diagnosed with an infection caused by the bacterium Mycobacterium ulcerans.
Mycobacterium ulcerans is the bacterium responsible for causing Buruli ulcer, a chronic, necrotizing disease of the skin and subcutaneous tissue. This infection is typically found in tropical and subtropical regions, particularly in parts of Africa, Australia, and South America. The bacterium is known for producing a toxin called mycolactone, which causes tissue destruction and ulceration.
Symptoms of Mycobacterium ulcerans infection can include painless ulcers, nodules, and swollen lymph nodes. Without prompt treatment, the infection can cause extensive tissue destruction and disability. Early diagnosis and treatment with antibiotics are crucial in order to prevent severe complications and long-term disabilities associated with Mycobacterium ulcerans infection.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1B21.20, which represents Mycobacterium ulcerans infection, is 308501009. This code is used in healthcare settings to document cases of this particular bacterial infection caused by Mycobacterium ulcerans. SNOMED CT codes are essential for accurate and detailed medical record keeping, as they provide a standardized way to catalog and classify various diseases and conditions. Healthcare professionals rely on these codes to quickly and accurately identify specific conditions and treatments, ensuring effective communication among providers. In the case of Mycobacterium ulcerans infection, using the SNOMED CT code 308501009 allows for clear and concise documentation of this uncommon but serious condition, aiding in proper diagnosis and treatment for affected patients.
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 1B21.20 (Mycobacterium ulcerans infection) typically present as painless nodules, papules, or plaques at the site of infection. These lesions may develop into open ulcers with undermined edges and a yellowish or purplish color. As the infection progresses, patients may experience swelling of the affected area and the development of thickened, rope-like structures known as cords.
In addition to skin lesions, individuals with Mycobacterium ulcerans infection may also experience systemic symptoms such as fever, fatigue, and weight loss. In some cases, the bacteria may release toxins that cause destruction of nerves and blood vessels, leading to further complications such as contractures and deformities. These symptoms may worsen over time if the infection is not promptly diagnosed and treated.
While Mycobacterium ulcerans infection primarily affects the skin and subcutaneous tissues, it has the potential to spread to deeper structures such as muscle and bone. In severe cases, the infection may cause extensive tissue destruction and necrosis, leading to the formation of large, disfiguring ulcers known as Buruli ulcers. Prompt recognition and treatment of Mycobacterium ulcerans infection are essential to prevent long-term complications and disability in affected individuals.
🩺 Diagnosis
Diagnosis of Mycobacterium ulcerans infection, coded as 1B21.20 in the medical classification system, often begins with a physical examination of the affected area. The characteristic symptom of this infection is the presence of painless nodules or ulcers on the skin, which may be accompanied by swollen lymph nodes. The next step in the diagnostic process typically involves laboratory tests to confirm the presence of Mycobacterium ulcerans bacteria in a sample taken from the affected area.
One of the most commonly used diagnostic methods for Mycobacterium ulcerans infection is polymerase chain reaction (PCR) testing. PCR testing allows for the amplification of DNA sequences specific to the bacteria, making it easier to detect their presence in a clinical sample. Another diagnostic tool that may be used is microscopy, which involves examining a sample under a microscope to look for characteristic features of Mycobacterium ulcerans bacteria, such as their rod-shaped appearance.
In some cases, more advanced diagnostic imaging techniques, such as ultrasound or MRI scans, may be employed to assess the extent of tissue damage caused by Mycobacterium ulcerans infection. These imaging tests can help healthcare providers determine the best course of treatment for the patient. Ultimately, a combination of clinical examination, laboratory tests, and imaging studies is typically used to diagnose and evaluate cases of Mycobacterium ulcerans infection.
💊 Treatment & Recovery
Treatment for Mycobacterium ulcerans infection, also known as Buruli ulcer, typically involves a combination of antibiotics and surgery. The antibiotics most commonly used include rifampicin and clarithromycin, administered for several weeks to months. The purpose of antibiotic therapy is to kill the bacteria responsible for the infection, particularly in the early stages when the disease is less severe.
In cases where the infection has progressed to more advanced stages, surgical intervention may be necessary to remove necrotic tissue and repair any damage caused by the bacteria. Surgical excision of infected tissue is often followed by skin grafting to promote healing and reduce scarring. In severe cases, amputation of affected limbs may be required to prevent the spread of infection and save the patient’s life.
Recovery from Mycobacterium ulcerans infection can be a long and challenging process, especially for individuals who have experienced significant tissue damage or require extensive surgery. Regular follow-up appointments with healthcare providers are essential to monitor the progress of treatment and address any complications that may arise. Physical therapy and wound care may also be necessary to optimize healing and restore function in affected limbs. With proper medical intervention and support, most patients can achieve full recovery from Buruli ulcer and resume normal activities.
🌎 Prevalence & Risk
In the United States, Mycobacterium ulcerans infection, also known as Buruli ulcer, is considered rare. Cases have been reported predominantly in the southeastern region of the country, particularly in states such as Texas and Florida. The prevalence of 1B21.20 in the United States is thought to be relatively low compared to other regions of the world.
In Europe, cases of Mycobacterium ulcerans infection are more commonly reported in certain countries such as France and Australia. The prevalence of 1B21.20 in Europe is generally higher compared to the United States, but still remains relatively low overall. Efforts to monitor and control the spread of Buruli ulcer in Europe are ongoing, with a focus on improving diagnosis and treatment strategies.
In Asia, Mycobacterium ulcerans infection is most commonly found in regions such as China, Malaysia, and Japan. The prevalence of 1B21.20 in Asia varies by country, with some areas experiencing higher rates of infection than others.
