Code Description

ICD-10 N90.6 is a billable code used to indicate a diagnosis of hypertrophy of vulva.

Key Diagnostic Point:

Hypertrophy of the vulva refers to an abnormal enlargement of the vulvar tissues, which can be due to various factors including hormonal changes, obesity, or genetic predisposition. This condition may present with symptoms such as discomfort, irritation, or cosmetic concerns. It is important to differentiate hypertrophy from other vulvar conditions such as lesions or inflammatory disorders. Diagnosis typically involves a thorough clinical examination and may require imaging or biopsy to rule out other pathologies. Treatment options vary based on the severity of symptoms and may include conservative management, surgical intervention, or hormonal therapy. Understanding the underlying causes is crucial for effective management and to prevent recurrence. Hypertrophy of the vulva is often associated with other noninflammatory disorders of the female genital tract, including conditions affecting the vagina and cervix, which may complicate the clinical picture.
