Corrosion of unsp degree of female genital region, sequela

This code indicates a long-term or residual effect resulting from a chemical burn (corrosion) to the female genital region. The original burn's severity is not specified, and this code is used to report the ongoing complications or conditions that arise after the acute phase of the injury has passed.

Use this code when documenting conditions such as scarring, chronic pain, strictures, or other permanent tissue damage in the female genital area that are directly attributable to a past chemical burn. This code is appropriate for follow-up encounters where the sequelae are being treated or monitored, not for the initial acute injury.

• Always use this code with an external cause code (V00-Y99) to identify the circumstances of the corrosion.
• Do not use this code for acute chemical burns; instead, refer to codes in the T20-T25 range for current injuries.
• Ensure documentation clearly links the current condition to a previous chemical burn and specifies it as a sequela.
