Corrosion of second degree of female genital region, sequela

This code signifies a second-degree chemical burn affecting the external female genitalia, specifically documenting a long-term complication or residual effect of the initial injury. A second-degree corrosion involves damage to the epidermis and dermis, characterized by blistering, pain, and potential scarring. The "sequela" designation indicates that this code is used for conditions that are a direct result of a previous corrosion, even if the acute injury has healed.

Use this code when documenting a current clinical condition, such as scarring, chronic pain, dyspareunia, or functional impairment, that is directly attributable to a past second-degree chemical burn of the female genital region. This applies when the original burn is no longer acute but has left lasting effects. It is appropriate for follow-up visits addressing these persistent issues.

• Always use an external cause code (V00-Y99) in conjunction with this code to identify the circumstances of the corrosion.
• Ensure documentation clearly links the current sequela to the previous second-degree chemical burn.
• Do not use this code for acute second-degree chemical burns; instead, use the appropriate acute corrosion code.
