Corrosion of first degree of left foot, sequela

This code signifies a first-degree corrosion (chemical burn) affecting the left foot, where the initial injury has healed, but residual effects or complications are now being addressed. First-degree corrosions typically involve only the epidermis, presenting with redness and mild pain without blistering. The "sequela" indicates that the current encounter is for a long-term consequence of this past injury.

Use this code when documenting a patient encounter for a condition directly resulting from a previously sustained first-degree chemical burn to the left foot. This could include chronic pain, scarring, altered sensation, or other persistent issues related to the original corrosion, after the acute phase of the injury has passed. Do not use this code for the initial treatment of the acute burn.

• Always assign an additional code to specify the nature of the sequela (e.g., chronic pain, scar formation).
• Ensure documentation clearly links the current condition to the past first-degree corrosion of the left foot.
• Verify the laterality (left foot) and degree of corrosion (first degree) are explicitly stated in the medical record.
