Corrosion of first degree of right lower leg, sequela

This code signifies a healed or chronic first-degree burn (erythema only) on the right lower leg, where the initial injury has resolved but residual effects or complications are now being treated. These sequelae could include scarring, contractures, or chronic pain directly attributable to the past corrosion.

Apply this code when a patient presents for treatment of a long-term complication or residual condition stemming from a first-degree corrosion on their right lower leg, and the original acute injury is no longer active. This is appropriate for follow-up care years after the initial burn, or when addressing permanent changes.

• Always ensure the documentation clearly links the current condition to the past first-degree corrosion of the right lower leg.
• Do not use this code for acute or active first-degree burns; those require codes from the acute burn section.
• Consider additional codes for specific sequelae, such as scar codes (e.g., L90.5) or chronic pain codes, if documented.
