Code Description

ICD-10 N90.4 is a billable code used to indicate a diagnosis of leukoplakia of vulva.

Key Diagnostic Point:

Leukoplakia of the vulva is characterized by the presence of white patches or plaques on the vulvar skin, which may be asymptomatic or associated with pruritus, irritation, or discomfort. This condition is often a result of chronic irritation or inflammation and can be linked to various factors, including human papillomavirus (HPV) infection, lichen sclerosus, or other dermatological conditions. While leukoplakia itself is not cancerous, it can be a precursor to squamous cell carcinoma, necessitating careful monitoring and evaluation. Diagnosis typically involves a thorough clinical examination and may require a biopsy to rule out malignancy. Treatment options vary based on the underlying cause and may include topical corticosteroids, immunomodulators, or surgical intervention in cases of significant dysplasia or malignancy. Regular follow-up is essential to monitor for any changes in the lesions and to manage any associated symptoms effectively.
