Corrosion of second degree of right foot, sequela

This code signifies a second-degree chemical burn affecting the right foot, where the acute injury has healed but residual effects or complications persist. These sequelae can include scarring, chronic pain, contractures, or other long-term consequences directly attributable to the original corrosion.

Apply this code when documenting a patient presenting with a current condition or complication that is a direct result of a previously sustained second-degree chemical burn to the right foot. This is appropriate for follow-up encounters addressing the long-term impact of the injury, not the initial acute treatment.

• Always use an external cause code (V00-Y99) in conjunction with this code to fully describe the circumstances of the original injury.
• Ensure documentation clearly links the current condition to the prior second-degree corrosion of the right foot.
• Do not use for acute chemical burns; this code is specifically for sequelae.
