Corrosion of first degree of female genital region, sequela

This code indicates a permanent scar, contracture, or other long-term complication resulting from a first-degree corrosion (chemical burn) to the female genital region. The initial injury has healed, but a residual effect persists.

Apply this code when documenting a patient presenting with a sequela, such as a scar or altered tissue texture, directly attributable to a past first-degree chemical burn of the external female genitalia. This code is appropriate for follow-up visits addressing these long-term consequences, not the acute injury.

• Always assign an external cause code (V00-Y99) to identify the circumstances of the corrosion.
• Do not use this code for active, healing burns; instead, use the appropriate acute corrosion code.
• The "S" in the 7th character indicates sequela and should be used for complications or conditions that are the residual effect of a healed injury.
