Transverse vaginal septum

This code represents a congenital anomaly of the female reproductive system characterized by a fibrous or muscular band of tissue that partially or completely obstructs the vaginal canal. This septum can be located at various levels within the vagina, leading to symptoms such as amenorrhea, dyspareunia, or difficulty with tampon insertion.

Use this code when documentation clearly indicates the presence of a transverse vaginal septum, whether identified during a physical examination, imaging studies (e.g., ultrasound, MRI), or surgical exploration. This diagnosis is typically made in adolescent females presenting with primary amenorrhea or other obstructive symptoms.

• Differentiate from other vaginal anomalies like longitudinal vaginal septum (Q52.10) or imperforate hymen (Q52.3).
• Ensure the documentation specifies "transverse" to avoid miscoding.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's an incidental finding or comorbidity.
