Longitudinal vaginal septum, microperforate, left side

This code describes a congenital anomaly of the female reproductive tract characterized by an incomplete longitudinal septum within the vagina that is located on the left side and contains small openings or perforations. This septum partially divides the vaginal canal, potentially causing symptoms such as dyspareunia, menstrual outflow obstruction, or difficulty with tampon insertion.

Use this code when documentation explicitly identifies a microperforate longitudinal vaginal septum on the left side. This diagnosis is typically made through physical examination, imaging studies like MRI or ultrasound, or during surgical exploration. Supporting documentation should clearly specify the laterality and the microperforate nature of the septum.

• Differentiate from complete or imperforate longitudinal vaginal septa, which have different code assignments.
• Ensure the documentation specifies "microperforate" and "left side" to accurately assign this specific code.
• Consider any associated anomalies of the uterus or kidneys, as these can co-occur with vaginal septa.
