Corrosion of unspecified degree of left foot, sequela

This code indicates a long-term complication or late effect resulting from a chemical burn or corrosion that affected the left foot. The original injury's severity (e.g., first, second, or third degree) is not specified, and the sequela could manifest as scarring, chronic pain, functional impairment, or other lasting issues.

Assign this code when documenting a current condition or symptom that is a direct consequence of a past corrosive injury to the left foot. This is appropriate for follow-up encounters addressing residual problems after the acute phase of the burn has healed.

• Always sequence this code after the code for the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a previous corrosive injury of the left foot.
• Do not use for acute corrosive injuries; this code is exclusively for sequelae.
