External constriction of vagina and vulva, sequela

This code signifies a long-term or late-effect condition where there is an abnormal narrowing or tightening of the external female genitalia (vagina and vulva) due to an external cause. This constriction can lead to various symptoms such as pain, dyspareunia, or difficulty with gynecological examinations, and is a residual effect of a past injury or event.

Use this code when documenting a patient presenting with ongoing symptoms or physical findings of external constriction of the vagina and vulva that is a sequela of a previous injury, surgery, or other external factor. This applies to conditions that are no longer acute but represent a lasting consequence. Examples include scarring from a previous trauma, burn, or surgical procedure that has resulted in chronic narrowing.

• Always code the underlying cause of the sequela first, if known and applicable, using an appropriate external cause code.
• Ensure documentation clearly indicates the constriction is a sequela and not an acute or current injury.
• Consider additional codes for any associated symptoms or complications, such as dyspareunia (N94.1) or pain (R10.2).
