ICD-11 code 2E63.00 corresponds to the diagnosis of lentigo maligna, a type of skin cancer classified under the melanoma category. Lentigo maligna is a form of melanoma in situ, meaning the abnormal melanocytes are confined to the epidermis without invading the underlying dermis. Lentigo maligna typically starts as a slowly growing patch of abnormal skin that fails to tan in the sun, often found on sun-exposed areas such as the face, neck, or arms.
It is crucial to differentiate lentigo maligna from lentigo maligna melanoma, which indicates invasion of malignant cells into the dermis. Timely detection and proper treatment of lentigo maligna are vital to prevent progression to lentigo maligna melanoma, a more aggressive form of skin cancer. The diagnosis of lentigo maligna is often confirmed through a skin biopsy, which allows a pathologist to examine the cells under a microscope and determine the extent of malignant transformation. Treatment options for lentigo maligna typically include surgical excision, cryotherapy, or topical therapies such as imiquimod or fluorouracil cream.

#️⃣ Coding Considerations
In the realm of medical coding, the SNOMED CT code equivalent to ICD-11 code 2E63.00, denoting Lentigo maligna, is 416859008. This specific code is used to classify and categorize the diagnosis of Lentigo maligna within the SNOMED CT system, which is widely utilized for clinical documentation and electronic health records. Lentigo maligna is a type of melanoma in situ, characterized by a slow-growing lesion on sun-exposed areas of the skin, often appearing as a pigmented patch with irregular borders. By assigning the appropriate SNOMED CT code to this condition, healthcare providers can accurately capture and communicate information about the patient’s diagnosis, facilitating effective treatment planning and monitoring of the disease progression. The SNOMED CT system provides a standardized way to represent clinical concepts, enabling interoperability and standardization in healthcare data exchange and analysis.
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
Lentigo maligna, also known as melanoma in situ, presents as a slowly growing, irregularly pigmented lesion on sun-exposed skin. The lesion typically appears as a flat, tan-to-brown patch with areas of darker pigment, irregular borders, and variations in color.
One of the primary symptoms of lentigo maligna is the gradual enlargement and darkening of the lesion over time. Patients may notice changes in the size, shape, and color of the lesion, which can indicate malignant transformation. In some cases, lentigo maligna may develop nodular or invasive components, leading to a more aggressive form of melanoma.
Another common symptom of lentigo maligna is the presence of irregularities in the texture and surface of the lesion. Patients may observe areas of scaling, crusting, or ulceration on the affected skin, which can be indicative of invasive growth. It is important to monitor any changes in the appearance or texture of the lesion and seek medical evaluation if there is concern for malignancy.
🩺 Diagnosis
Diagnosis methods for Lentigo maligna (ICD-10 code 2E63.00) typically involve a thorough examination of the affected skin lesion. Dermatologists may use a dermatoscope, a handheld device with a magnifying lens and light, to closely inspect the lesion for irregularities in color, shape, and texture. Additionally, a biopsy may be performed to extract a sample of tissue from the lesion for further analysis under a microscope.
During a dermatoscopic examination, the dermatologist will look for key features that suggest malignancy, such as asymmetry, irregular borders, varying colors, and structural changes within the lesion. These features can help differentiate Lentigo maligna from other benign skin lesions or melanoma subtypes. The dermatologist will also assess the lesion’s size, location, and any changes over time to determine the likelihood of malignancy.
If the dermatologist suspects Lentigo maligna based on the clinical and dermatoscopic evaluation, a skin biopsy will be performed to confirm the diagnosis. A small sample of tissue will be removed from the lesion using a local anesthetic, and the sample will be sent to a pathology laboratory for examination under a microscope. The pathologist will assess the tissue for characteristic features of Lentigo maligna, such as atypical melanocytes along the dermoepidermal junction, to confirm the diagnosis and determine the extent of the lesion.
💊 Treatment & Recovery
Treatment for Lentigo maligna (2E63.00) often involves a combination of surgical and non-surgical options to effectively remove the cancerous cells while preserving as much nearby healthy tissue as possible. The primary treatment for Lentigo maligna is surgical excision, where the abnormal skin cells are cut out along with a margin of healthy tissue to ensure all cancerous cells are removed. This procedure may be done using a scalpel or laser depending on the size and location of the cancerous lesion.
In cases where surgical excision is not possible or may be too invasive, other treatment options such as cryotherapy, radiation therapy, or topical therapies may be used to target and destroy the cancerous cells. Cryotherapy involves freezing the cancerous cells with liquid nitrogen, while radiation therapy uses high-energy x-rays to kill cancer cells. Topical therapies, such as imiquimod cream, are applied directly to the skin lesion to stimulate the immune system’s response against the cancer.
Following treatment, patients with Lentigo maligna require close monitoring to ensure the cancer does not recur or spread. Regular follow-up appointments with a dermatologist or oncologist are typically recommended to track any changes in the skin and detect early signs of recurrence. Additionally, sun protection measures, such as wearing sunscreen and protective clothing, are essential for preventing further damage to the skin and reducing the risk of developing additional skin cancers.
🌎 Prevalence & Risk
In the United States, Lentigo maligna is considered to be a relatively rare form of skin cancer. The prevalence of 2E63.00 is estimated to be around 2-5% of all melanomas. However, the incidence of Lentigo maligna has been increasing in recent years, possibly due to increased awareness and improved diagnostic techniques.
In Europe, Lentigo maligna is also considered to be a rare type of melanoma. The prevalence of 2E63.00 varies across different European countries, with some regions reporting higher rates than others. Overall, the incidence of Lentigo maligna appears to be increasing in Europe, similar to trends observed in the United States.
In Asia, Lentigo maligna is less common compared to other types of skin cancer. The prevalence of 2E63.00 is relatively low in Asian populations, with some countries reporting very few cases. However, due to changing lifestyles and increased exposure to risk factors such as UV radiation, the incidence of Lentigo maligna may be on the rise in certain parts of Asia.
In Australia, Lentigo maligna is more prevalent compared to other regions, possibly due to the country’s high levels of UV radiation. The prevalence of 2E63.00 is estimated to be higher in Australia compared to other countries, with a significant proportion of melanomas being diagnosed as Lentigo maligna. The incidence of Lentigo maligna is particularly high in regions with a large Caucasian population, which is more susceptible to skin cancer.
😷 Prevention
To prevent Lentigo maligna, also known as 2E63.00, individuals can take certain precautions to reduce their risk of developing this condition. One of the most important preventive measures is to limit sun exposure and practice sun safety techniques. This includes wearing protective clothing, such as hats and long sleeves, using sunscreen with a high SPF, and seeking shade during peak sun hours.
Furthermore, individuals should regularly examine their skin for any suspicious changes, such as new moles or changes in existing moles. Early detection and prompt treatment of suspicious skin lesions can help prevent the progression of Lentigo maligna. It is also essential to avoid tanning beds, as they can increase the risk of developing skin cancer, including Lentigo maligna.
Lastly, individuals with a history of excessive sun exposure, a family history of skin cancer, or fair skin should be especially vigilant about monitoring their skin and seeking regular skin screenings from a healthcare provider. By taking these preventive measures, individuals can reduce their risk of developing Lentigo maligna and other skin cancers.
🦠 Similar Diseases
Lentigo maligna is a type of melanoma in situ that primarily affects sun-exposed areas of the skin in older individuals. This disease is characterized by a slow progression and commonly presents as a large, irregularly pigmented lesion. While Lentigo maligna is a distinct clinical entity, there are several other skin conditions that share similar features and may be confused with it.
One such disease is lentigo simplex, also known as simple lentigo. Lentigo simplex is a benign pigmented lesion that is typically flat, small, and uniform in color. Unlike Lentigo maligna, lentigo simplex does not have the potential to progress to invasive melanoma. However, both conditions can appear similar on clinical examination, making accurate diagnosis crucial.
Another disease that can resemble Lentigo maligna is solar lentigo, also called senile lentigo or liver spots. Solar lentigines are benign, flat pigmented spots that develop on sun-exposed areas of the skin in response to chronic sun exposure. While solar lentigines are harmless and do not have the potential to develop into melanoma, their appearance can be similar to Lentigo maligna, leading to potential diagnostic confusion.
Dysplastic nevus, also known as atypical mole, is another skin condition that shares some features with Lentigo maligna. Dysplastic nevi are benign moles that exhibit atypical features such as irregular borders, variegated color, and a larger size compared to normal moles. While dysplastic nevi are not a direct precursor to Lentigo maligna, they can sometimes be mistaken for early-stage melanoma due to their atypical appearance. Proper evaluation and monitoring are necessary to distinguish between dysplastic nevi and Lentigo maligna.
