Code Description

ICD-10 N90.7 is a billable code used to indicate a diagnosis of vulvar cyst.

Key Diagnostic Point:

A vulvar cyst is a benign, fluid-filled sac that forms on the vulva, which is the external part of the female genitalia. These cysts can arise from various glands, such as Bartholin's glands, or from the skin itself. Vulvar cysts are often asymptomatic but can cause discomfort, pain, or irritation, particularly if they become inflamed or infected. The most common types of vulvar cysts include Bartholin's cysts, sebaceous cysts, and epidermoid cysts. Diagnosis typically involves a physical examination, and imaging studies may be used if the cyst is large or symptomatic. Treatment options vary depending on the size and symptoms of the cyst, ranging from observation to surgical intervention. In some cases, drainage or excision may be necessary, especially if the cyst is recurrent or causing significant discomfort. Vulvar cysts are generally not associated with malignancy, but proper evaluation is essential to rule out other conditions, including neoplasms or infections.
