Fusion of labia

This code represents the pathological adherence or joining of the labia minora or majora, often resulting in partial or complete obstruction of the vaginal introitus. This condition can be congenital or acquired, commonly seen in prepubertal females due to inflammation or estrogen deficiency, or in postmenopausal women.

Use this code for documented cases of labial fusion, synechiae, or agglutination. This diagnosis is typically supported by physical examination findings detailing the extent and location of the labial adhesion. It is frequently encountered in pediatric gynecology or general pediatrics.

• Differentiate from other congenital malformations of the female external genitalia (Q52.x series) which involve structural abnormalities rather than adhesion.
• Consider an additional code for any underlying cause, such as vulvovaginitis (N76.x), if documented.
• Ensure documentation specifies "fusion" or "adhesion" of the labia, not simply hypoplasia or other developmental anomalies.
