Open bite of vagina and vulva, sequela

This code describes the long-term effects or complications arising from an open bite injury to the vagina and vulva. This could include scarring, chronic pain, nerve damage, or functional impairment that persists after the initial wound has healed. It signifies that the original injury is no longer acute but has left lasting sequelae.

Assign this code when documenting and billing for treatment of conditions that are a direct consequence of a past open bite to the external female genitalia. This is appropriate for follow-up care, reconstructive procedures, or management of chronic issues related to the original injury. Do not use for the initial acute injury.

• Requires a seventh character of 'S' to indicate sequela.
• Always link to an external cause code (V00-Y99) to specify the circumstances of the original bite if known.
• Consider additional codes for specific sequelae, such as chronic pain (G89.-) or scar formation (L90.5).
