Corrosion of third degree of female genital region, sequela

This code signifies a third-degree chemical burn (corrosion) to the external female genitalia, including the vulva, labia, and perineum, where the initial injury has healed and the patient is now presenting with a residual condition or complication directly resulting from that past burn. Third-degree burns involve full-thickness destruction of the skin and underlying tissue.

Use this code when documenting a sequela, such as scarring, contracture, chronic pain, or functional impairment, that is a direct consequence of a previously sustained third-degree chemical burn to the female genital region. This code is appropriate for follow-up encounters after the acute phase of the burn has resolved.

• Assign this code only for conditions that are residual effects of a healed third-degree corrosion.
• Do not use for acute burns; instead, use the appropriate acute burn code.
• Always sequence this sequela code first, followed by codes for the specific residual condition(s) being treated.
