Corrosion of first degree of unspecified foot, sequela

This code indicates a healed or chronic first-degree chemical burn (corrosion) on an unspecified part of the foot. It signifies that the initial injury has resolved, but there are lasting effects or complications from the burn.

Apply this code when documenting a patient presenting with a long-term consequence or residual condition directly attributable to a past first-degree chemical burn of the foot. This is used for follow-up care related to the sequela, not the acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, chronic pain).
• Ensure documentation clearly states the burn was chemical (corrosion) and first-degree.
• Verify the laterality of the foot is truly unspecified in the medical record before using this code.
