ICD-11 code 2B01, also known as mycosis fungoides, is a form of cutaneous T-cell lymphoma, a type of cancer that affects the skin. Mycosis fungoides typically presents with patches or plaques on the skin that may resemble eczema or psoriasis. Over time, these patches can progress to tumors and spread to other parts of the body.
The exact cause of mycosis fungoides is unknown, but it is believed to be related to a mutation in T-cells, which are a type of white blood cell that plays a crucial role in the immune system. Risk factors for developing mycosis fungoides include older age, male gender, and a history of certain skin conditions like psoriasis.
Diagnosis of mycosis fungoides typically involves a skin biopsy to examine the affected skin cells under a microscope. Treatment options for mycosis fungoides may include topical medications, phototherapy, chemotherapy, or immunotherapy, depending on the stage and severity of the disease. Prognosis for mycosis fungoides can vary based on the individual case, with early detection and treatment leading to better outcomes.

#️⃣ Coding Considerations
SNOMED CT code 418290006 corresponds to the ICD-11 code 2B01, which represents Mycosis fungoides, a type of non-Hodgkin lymphoma that primarily affects the skin. This rare form of cancer typically presents as red, scaly patches or raised bumps on the skin, which can progress to tumors over time. Mycosis fungoides is most commonly diagnosed in adults over the age of 50 and can be challenging to differentiate from other skin conditions. The SNOMED CT code provides a standardized way to accurately document and track cases of Mycosis fungoides in electronic health records, allowing for improved communication and data analysis among healthcare professionals. This code facilitates the exchange of clinical information related to the diagnosis and treatment of this specific type of lymphoma, ultimately contributing to better patient care and outcomes.
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 2B01 (Mycosis fungoides) typically manifest as skin lesions that may initially appear as patches or plaques on the skin. These lesions may cause itching and sometimes pain, and they often resemble eczema or psoriasis. As the disease progresses, the lesions may become thicker and more pronounced, developing into tumors known as nodules.
In addition to skin lesions, individuals with 2B01 may also experience symptoms such as skin redness, scaling, and ulceration. These symptoms can vary in severity and may worsen over time as the disease advances. It is not uncommon for individuals with 2B01 to develop a generalized rash or have enlarged lymph nodes as the condition progresses.
Furthermore, individuals with 2B01 may experience systemic symptoms such as fatigue, fever, and weight loss. These symptoms can be nonspecific and may be mistaken for other conditions, leading to a delay in diagnosis. It is important for individuals experiencing persistent skin changes or systemic symptoms to seek medical evaluation for proper diagnosis and management of 2B01.
🩺 Diagnosis
Diagnosis of 2B01 (Mycosis fungoides) typically involves a combination of clinical evaluation, skin biopsy, and various laboratory tests. A dermatologist will first conduct a thorough physical examination to assess the appearance of the skin lesions and any accompanying symptoms. The characteristic features of mycosis fungoides include scaly patches, plaques, and tumors that may resemble eczema or psoriasis.
Skin biopsy is an essential diagnostic procedure for confirming the presence of mycosis fungoides. During a biopsy, a small sample of skin tissue is extracted and examined under a microscope to identify abnormal cells characteristic of the disease. In addition to the biopsy, other laboratory tests such as blood tests and immunohistochemistry may be performed to help differentiate mycosis fungoides from other skin conditions.
Once a diagnosis of mycosis fungoides is confirmed, further tests may be conducted to determine the extent and stage of the disease. These may include imaging studies such as X-rays, CT scans, or MRIs to assess the involvement of internal organs or lymph nodes. The staging of mycosis fungoides is crucial for determining the appropriate treatment strategy and prognosis for the patient.
💊 Treatment & Recovery
Treatment for 2B01 (Mycosis fungoides) often involves a combination of therapies aimed at controlling the symptoms and slowing the progression of the disease. The choice of treatment depends on the individual patient’s stage of the disease, overall health, and other factors.
One common treatment option is topical medications, such as corticosteroids or chemotherapy agents, applied directly to the skin lesions. These medications can help reduce inflammation and promote healing of the affected areas. In some cases, doctors may recommend phototherapy, which involves exposing the skin to ultraviolet light to target cancer cells.
For more advanced cases of 2B01 (Mycosis fungoides), systemic treatments like chemotherapy, targeted therapy, or immunotherapy may be necessary. These medications are taken orally or administered intravenously to target cancer cells throughout the body. In some cases, a combination of different therapies may be recommended to achieve the best possible outcome for the patient.
Recovery from 2B01 (Mycosis fungoides) is an ongoing process that often requires long-term management and monitoring. Regular follow-up appointments with a dermatologist or oncologist are essential to track the progress of the disease, monitor side effects of treatment, and make any necessary adjustments to the treatment plan. Patients are encouraged to maintain good overall health habits, including a balanced diet, regular exercise, and avoiding environmental factors that may exacerbate skin symptoms. Support from family, friends, and support groups can also play a crucial role in helping patients cope with the physical and emotional challenges of living with 2B01 (Mycosis fungoides).
🌎 Prevalence & Risk
In the United States, mycosis fungoides is considered the most common form of cutaneous T-cell lymphoma, accounting for approximately 50% of all cases. The annual incidence of mycosis fungoides in the United States is estimated to be 0.36 per 100,000 individuals, with a higher prevalence in older adults.
In Europe, mycosis fungoides is also recognized as the most prevalent form of cutaneous T-cell lymphoma. Studies have shown varying incidence rates across different European countries, with some countries reporting higher rates than others. Overall, mycosis fungoides is considered a rare disease in Europe compared to other skin conditions.
In Asia, mycosis fungoides is less commonly reported compared to Western countries. Limited studies on the prevalence of mycosis fungoides in Asia have been conducted, making it difficult to determine the exact incidence rate in the region. However, some studies have suggested that mycosis fungoides may be underdiagnosed in Asia due to lack of awareness and access to specialized healthcare.
In Africa, the prevalence of mycosis fungoides is also relatively low compared to other continents. Limited data is available on the incidence of mycosis fungoides in Africa, making it challenging to fully assess the burden of the disease in the region. Further research is needed to better understand the prevalence of mycosis fungoides in Africa and other regions outside of North America and Europe.
😷 Prevention
To prevent 2B01 (Mycosis fungoides), it is important to avoid known risk factors associated with the disease. This includes limiting exposure to ultraviolet radiation, as sunlight is a known trigger for the development of cutaneous T-cell lymphoma, including mycosis fungoides. Individuals should take precautions such as wearing protective clothing, applying sunscreen, and seeking shade during peak sun hours to reduce their risk of developing the disease.
Another key preventive measure for 2B01 is to maintain overall skin health and hygiene. This includes regular bathing with mild soap, moisturizing the skin to prevent dryness and itching, and avoiding harsh skincare products that can irritate the skin. Keeping the skin well-nourished and hydrated can help strengthen the skin barrier and reduce the risk of developing skin conditions like mycosis fungoides.
In addition to these measures, individuals with a family history of mycosis fungoides or other skin conditions should be vigilant about monitoring their skin and seeking regular medical check-ups. Early detection and treatment of any skin changes or abnormalities can improve outcomes and reduce the risk of developing more advanced stages of mycosis fungoides. By staying informed about the disease and its risk factors, individuals can take proactive steps to protect their skin health and lower their risk of developing 2B01 (Mycosis fungoides).
