Corrosion of unspecified degree of left lower leg, sequela

This code signifies a long-term complication or late effect resulting from a corrosive burn of an unspecified degree affecting the left lower leg. It indicates that the initial injury has healed, but residual issues or conditions persist due to the burn.

Apply this code when documenting a patient presenting with a chronic problem, scar, contracture, or other lasting consequence directly attributable to a corrosive burn on their left lower leg that occurred in the past. This is used after the acute phase of the burn has resolved.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a past corrosive burn of the left lower leg.
• Do not use this code for active, acute corrosive burns; those require codes from the initial encounter or subsequent encounter categories.
