ICD-11 code 1F2D.3 corresponds to the medical condition known as black piedra. Black piedra is a rare fungal infection of the hair shafts, primarily affecting the scalp and genital hair. It is characterized by the formation of small, dark nodules that adhere to the hair strands, leading to a weakening and breakage of the hair.
The nodules in black piedra are caused by the fungus Piedraia hortae, which thrives in warm and humid environments. While the exact mode of transmission is not fully understood, it is believed to occur through direct contact with contaminated hair or shared grooming tools. Black piedra is more commonly found in tropical regions, where the climate is conducive to fungal growth.
Symptoms of black piedra may include itchiness, hair loss, and a foul-smelling discharge from the affected hair follicles. Diagnosis is typically made through microscopic examination of the nodules, which may reveal the presence of fungal spores and hyphae. Treatment usually involves antifungal medications, such as topical creams or oral pills, to eliminate the infection and prevent recurrence.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1F2D.3 for Black piedra is 42179001. This code specifically refers to the disease caused by a fungus known as Piedraia hortae, which affects the hair shafts and results in the formation of hard nodules.
The SNOMED CT code further categorizes Black piedra as a type of superficial mycosis, providing healthcare professionals with a detailed classification for this specific fungal infection. By using this standardized code, healthcare providers can accurately document and track cases of Black piedra in their patient populations.
In addition, the SNOMED CT code for Black piedra allows for interoperability across different healthcare systems and facilitates data sharing for public health research and surveillance purposes. This ensures consistency and accuracy in the coding and classification of Black piedra cases worldwide.
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
The symptoms of 1F2D.3, also known as Black piedra, primarily manifest in the hair shafts. Infected individuals may notice the presence of small, black nodules tightly attached to the hair shafts. These nodules are composed of dark, hardened fungal growth that can lead to the weakening and breakage of the hair.
Affected individuals may also experience itching or discomfort in the infected areas of the scalp or body. The presence of Black piedra can potentially cause hair loss or thinning in severe cases. It is important for individuals experiencing these symptoms to seek medical attention and diagnosis from a healthcare professional.
In some instances, the nodules formed by Black piedra can be mistaken for other hair conditions or infections. Therefore, a thorough examination and evaluation by a healthcare provider may be necessary to correctly diagnose and treat Black piedra. It is crucial for individuals with symptoms of hair abnormalities or infections to seek proper medical guidance for appropriate management and care.
🩺 Diagnosis
Diagnosis methods for 1F2D.3 (Black piedra) typically involve a physical examination of the affected hair and scalp. The distinctive appearance of black nodules attached along the hair shafts is a key characteristic of black piedra. Dermatologists may use a magnifying lens or microscope to closely examine the affected hairs for the presence of these black nodules.
In addition to visual inspection, laboratory tests such as microscopic examination of the affected hair samples may be performed to confirm the presence of black piedra. A potassium hydroxide (KOH) preparation test can help to distinguish black piedra from other scalp conditions such as dandruff or fungal infections. This test involves adding a drop of KOH solution to the hair sample, which helps to dissolve and visualize the fungal elements present in black piedra.
If necessary, a fungal culture may be conducted to identify the specific species of fungus causing the black piedra infection. This involves collecting a sample of the affected hair and sending it to a laboratory for analysis. By identifying the exact fungus responsible for the infection, healthcare providers can determine the most effective treatment plan for managing black piedra.
💊 Treatment & Recovery
Treatment for 1F2D.3, also known as Black piedra, typically involves the use of antifungal medications. These medications may be administered orally or topically, depending on the severity of the infection. It is important for individuals with Black piedra to follow their healthcare provider’s instructions closely to ensure proper treatment.
In some cases, the affected hair may need to be removed to fully eliminate the infection. This can be done through shaving or using antifungal shampoos. It is essential to maintain good hygiene practices during treatment to prevent the spread of the infection and aid in recovery.
Recovery from Black piedra is typically successful with prompt and appropriate treatment. The infection usually responds well to antifungal medications, and symptoms should start to improve within a few weeks. However, it is important to continue treatment as prescribed by a healthcare provider to prevent the infection from recurring. Regular follow-up appointments may be necessary to monitor progress and ensure complete recovery.
🌎 Prevalence & Risk
The prevalence of 1F2D.3, also known as Black piedra, varies among regions around the world. In the United States, cases of Black piedra are rare, with only a few documented cases reported each year.
