Longitudinal vaginal septum, obstructing, right side

This code signifies a congenital anomaly of the female reproductive system where a fibrous or muscular wall divides the vaginal canal longitudinally, specifically on the right side, and is causing an obstruction. This septum can lead to symptoms such as dyspareunia, menstrual outflow obstruction, or difficulty with tampon insertion.

Apply this code when documentation clearly indicates a diagnosis of a right-sided longitudinal vaginal septum that is causing an obstruction. This typically occurs in patients presenting with symptoms related to the obstruction, confirmed by physical examination or imaging studies like ultrasound or MRI.

• Ensure documentation specifies "obstructing" and "right side" to accurately assign this code.
• Differentiate from non-obstructing septa (Q52.10) or those on the left side (Q52.122).
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter and treatment.
