Imperforate hymen

This code represents a congenital anomaly where the hymen completely obstructs the vaginal opening, preventing the outflow of menstrual blood or other vaginal secretions. It is a developmental defect of the female reproductive system, typically presenting at puberty.

Use this code for female patients diagnosed with an imperforate hymen, often identified during adolescence due to symptoms like primary amenorrhea with cyclic abdominal pain, or a bulging hymen. Documentation should clearly state the diagnosis of an imperforate hymen, often confirmed by physical examination.

• Do not confuse with other hymenal anomalies like microperforate or septate hymen, which have different codes.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter (e.g., for surgical correction).
• Ensure documentation specifies "imperforate" to differentiate from other hymenal conditions.
