Corrosion of second degree of buttock, sequela

This code signifies a second-degree chemical burn (corrosion) affecting the buttock, where the acute injury has healed but residual effects or complications persist. These sequelae might include scarring, contractures, chronic pain, or functional limitations directly attributable to the original corrosion.

Apply this code when documenting a patient presenting with long-term complications or residual conditions stemming from a previously sustained second-degree chemical burn to the buttock. This is appropriate for follow-up encounters addressing the chronic impact of the injury, rather than the initial acute treatment.

• Always use in conjunction with an external cause code (V00-Y99) to describe the circumstances of the corrosion, if known.
• Consider additional codes for specific sequelae, such as L90.5 for scar conditions or M24.5 for contracture, if applicable and documented.
• Ensure documentation clearly distinguishes between acute injury treatment and follow-up for chronic sequelae.
