Other and unspecified longitudinal vaginal septum

This code represents a congenital anomaly of the female reproductive system characterized by a fibrous or muscular band extending longitudinally within the vagina, partially or completely dividing it. This septum can result in a double vagina or a vagina with a partial internal division.

Use this code for documented cases of a longitudinal vaginal septum that is not otherwise specified as transverse or imperforate. This diagnosis is typically made during a physical examination or imaging studies such as ultrasound or MRI.

• Ensure documentation specifies "longitudinal" and not "transverse" to avoid miscoding.
• Do not use this code if the septum is described as imperforate; a more specific code would apply.
• Consider sequencing this code with other congenital anomalies if present, following official coding guidelines.
