Corrosion of first degree of right foot, sequela

This code signifies a first-degree chemical burn (corrosion) affecting the right foot, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly resulting from that past corrosion. First-degree burns typically involve only the epidermis, causing redness and mild pain without blistering.

Apply this code when documenting a follow-up encounter for a patient experiencing a long-term effect or complication stemming from a previously sustained first-degree chemical burn to their right foot. Examples include persistent discoloration, altered sensation, or scar tissue formation that requires ongoing management. This code is not for the initial acute injury.

• Always assign a sequela code when the patient is being treated for a residual condition or complication of a past injury, not the acute injury itself.
• Ensure documentation clearly links the current condition to the previous first-degree corrosion of the right foot.
• Do not use this code for thermal burns; it is specifically for chemical burns (corrosion).
