Longitudinal vaginal septum, nonobstructing

This code describes a congenital anomaly of the female reproductive system characterized by a fibrous or muscular wall running lengthwise within the vagina, which does not impede vaginal function or outflow. This septum divides the vaginal canal into two distinct, but often unequal, passages. It is typically asymptomatic and discovered incidentally during gynecological examination.

Use this code when documentation clearly indicates the presence of a longitudinal vaginal septum that is explicitly stated as nonobstructing. This diagnosis is often made during routine pelvic exams, colposcopy, or imaging studies (e.g., MRI, ultrasound) performed for other reasons. Documentation should confirm the septum's presence and lack of associated symptoms like dyspareunia, menstrual flow obstruction, or difficulties with tampon insertion.

• Ensure documentation explicitly states "nonobstructing" to differentiate from obstructing septa.
• Do not confuse with transverse vaginal septum (Q52.11) or other congenital malformations of the vagina.
• Code any associated symptoms or conditions separately, if present and documented (e.g., dyspareunia if the septum is causing it, though this code implies absence of obstruction).
