Unspecified open wound of vagina and vulva, sequela

This code describes a past injury to the external female genitalia (vulva) or the birth canal (vagina) that resulted in an open wound, where the specific nature of the wound is not documented. The "S" at the end indicates that this code is for a sequela, meaning it's used to report a condition that is a late effect or complication of the original injury, not the acute injury itself.

This code is appropriate for documenting long-term complications or residual effects stemming from an unspecified open wound of the vagina or vulva that occurred in the past. Examples include chronic pain, scarring, or functional impairment directly attributable to the original injury, when the specific type of open wound was never identified. It should be used when the patient is presenting for treatment of these late effects, not for the initial wound.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
• Do not use this code for acute open wounds; instead, refer to the acute injury codes within the S31 category.
• Ensure documentation clearly links the current condition to a past unspecified open wound of the vagina or vulva.
