Tight hymenal ring

This code describes an abnormally constricted hymenal opening, which can cause discomfort, dyspareunia, or difficulty with gynecological examinations. It refers to a hymen that is present but has an unusually small or rigid opening, rather than being completely closed.

Assign this code when documentation specifies a tight or rigid hymenal ring causing symptoms or requiring intervention. This is typically diagnosed during a physical examination where the hymen's opening is noted to be smaller than normal, impeding passage or causing pain.

• Differentiate from an imperforate hymen, which is a complete closure and is excluded from this code.
• Ensure documentation clearly states "tight" or "rigid" hymen, not just "small" without further context.
• Consider additional codes for associated symptoms like dyspareunia (N94.1) if documented.
