ICD-11 code 1F2D.0 corresponds to the medical condition known as Pityriasis versicolor. Pityriasis versicolor is a common fungal infection of the skin that leads to the development of discolored patches or spots.
The condition is caused by the fungus Malassezia, which is naturally present on the skin but can overgrow and lead to Pityriasis versicolor. This condition is often characterized by patches of skin that are lighter or darker than the surrounding skin, causing a noticeable discoloration.
Pityriasis versicolor typically occurs on areas of the skin that are warm and moist, such as the chest, back, and upper arms. Treatment options for Pityriasis versicolor may include antifungal medications, medicated shampoos, and topical creams to help manage the infection and restore the skin’s normal appearance.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1F2D.0, which pertains to Pityriasis versicolor, is 47715008. This code specifically identifies the skin condition characterized by the presence of small, discolored patches on the skin due to a fungal infection. SNOMED CT, or Systematized Nomenclature of Medicine Clinical Terms, is a comprehensive clinical terminology database used for coding and sharing healthcare information globally. The use of standardized codes such as SNOMED CT enables medical professionals to accurately document and communicate diagnoses, treatments, and other medical data. By utilizing precise codes like 47715008 for Pityriasis versicolor, healthcare providers can enhance the interoperability and accuracy of electronic health records, leading to more effective and efficient patient care.
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
Pityriasis versicolor, also known as tinea versicolor, is a common fungal skin infection that is characterized by discolored patches on the skin. These patches can appear as pink, red, tan, or white, and may be more noticeable on tanned or dark skin. The areas affected by pityriasis versicolor may be itchy or dry, though some individuals may not experience any symptoms at all.
One of the key symptoms of pityriasis versicolor is the presence of round or oval-shaped patches on the skin. These patches are typically flat, and may be more noticeable on the chest, back, neck, and upper arms. In some cases, the affected skin may appear scaly or flaky, particularly when the skin is warm or damp.
Individuals with pityriasis versicolor may also notice a change in the color of their skin, which can range from lighter to darker than the surrounding skin. This discoloration may be more pronounced in individuals with darker skin tones. Additionally, those affected by this condition may experience mild itching or discomfort in the affected areas, though severe pain or irritation is rare.
🩺 Diagnosis
Diagnosis of pityriasis versicolor, identified as 1F2D.0 in the ICD-11 coding system, typically involves a combination of clinical evaluation and laboratory tests. The condition is commonly diagnosed based on the characteristic appearance of the rash, which includes patches of discolored skin that may be lighter or darker than the surrounding skin. Skin scraping or biopsy may be performed to confirm the diagnosis by examining the presence of yeast cells under a microscope.
In some cases, a Wood’s lamp examination may be used to aid in the diagnosis of pityriasis versicolor. This handheld ultraviolet light can help identify areas of the skin affected by the condition by causing the affected patches to fluoresce differently than the normal skin. Additionally, a KOH (potassium hydroxide) preparation may be performed on skin scrapings to visualize the hyphae of the causative yeast organism, Malassezia furfur, under the microscope.
Differential diagnoses may need to be considered when working to confirm a diagnosis of pityriasis versicolor. Other skin conditions, such as tinea versicolor, seborrheic dermatitis, and pityriasis rosea, can present with similar symptoms and may require specific diagnostic tests to differentiate from pityriasis versicolor. In cases where the diagnosis is uncertain or the rash does not respond to treatment, consultation with a dermatologist may be recommended for further evaluation and management.
💊 Treatment & Recovery
Treatment and recovery methods for 1F2D.0, also known as Pityriasis versicolor, typically involve the use of antifungal medications. These medications may be applied topically in the form of creams, lotions, or shampoos, or taken orally in severe cases. It is important to follow the prescribed treatment regimen strictly to ensure full recovery.
In addition to medication, maintaining good skin hygiene is essential in treating and preventing recurrence of Pityriasis versicolor. Keeping the affected areas clean and dry can help prevent the fungus from spreading. Avoiding tight clothing and using antifungal powders may also be beneficial in managing the condition.
For individuals with recurrent or severe cases of Pityriasis versicolor, consult a dermatologist for further evaluation and tailored treatment options. In some cases, a combination of antifungal medications with other treatments, such as phototherapy or chemical peels, may be recommended to achieve optimal results. Regular follow-ups with a healthcare provider are important to monitor progress and make necessary adjustments to the treatment plan.
🌎 Prevalence & Risk
In the United States, the prevalence of Pityriasis versicolor, also known as 1F2D.0, is estimated to be relatively low. The condition is more commonly found in regions with warm and humid climates, such as the southern parts of the country. Despite this, cases of Pityriasis versicolor have been reported throughout the country, particularly during the summer months.
In Europe, the prevalence of Pityriasis versicolor varies depending on the region. Countries with warmer climates, such as Spain and Italy, tend to have higher rates of the condition compared to countries in northern Europe. Overall, Pityriasis versicolor is considered to be a relatively common skin disorder in Europe, particularly in Mediterranean regions where the climate is conducive to fungal growth.
In Asia, the prevalence of Pityriasis versicolor is relatively high, especially in tropical and subtropical regions. Countries such as India, Indonesia, and the Philippines have reported a significant number of cases. The warm and humid climate in many parts of Asia provides an ideal environment for the growth of the fungus responsible for causing Pityriasis versicolor.
In Africa, the prevalence of Pityriasis versicolor is also significant, particularly in regions with warm and humid climates. Countries in sub-Saharan Africa, such as Nigeria and Ghana, have reported a relatively high number of cases. The condition is more prevalent in rural areas where access to proper healthcare and hygiene practices may be limited.
😷 Prevention
To prevent Pityriasis versicolor, also known as 1F2D.0, individuals can take certain measures to minimize their risk of developing this skin condition. The primary cause of Pityriasis versicolor is the overgrowth of a type of yeast called Malassezia on the skin. To prevent this overgrowth, individuals should maintain good skin hygiene by regularly washing and drying their skin, especially in areas prone to sweating.
Another way to prevent Pityriasis versicolor is to avoid using oily or greasy products on the skin, as these can provide an environment conducive to the growth of Malassezia. Individuals should also wear loose, breathable clothing to minimize sweating, which can contribute to the growth of yeast on the skin. Additionally, it is important for individuals to avoid sharing clothing, towels, or other personal items that may harbor the yeast responsible for Pityriasis versicolor.
Furthermore, individuals can prevent Pityriasis versicolor by spending time in well-ventilated, dry environments and avoiding excessive heat and humidity, which can promote the growth of Malassezia on the skin. By following these preventative measures, individuals can reduce their risk of developing Pityriasis versicolor and maintain healthy skin.
