Corrosion of third degree of left lower leg, sequela

This code signifies a permanent complication or late effect resulting from a third-degree corrosion (chemical burn) that occurred on the patient's left lower leg. These sequelae can include chronic pain, scarring, contractures, or non-healing ulcers that persist long after the initial injury has healed.

Use this code when documenting a current condition that is a direct consequence of a previously sustained third-degree chemical burn to the left lower leg. This applies to follow-up encounters for ongoing management of these long-term effects, not for the initial acute injury.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to the past third-degree corrosion of the left lower leg.
• Do not use this code for acute chemical burns; those require codes from the T24.3-T24.4 range.
