Corrosion of third degree of left thigh, sequela

This code signifies a deep, full-thickness burn injury to the left thigh that has progressed beyond the acute healing phase. It indicates that the patient is experiencing long-term complications or residual effects stemming from the original third-degree corrosion. These sequelae can include scarring, contractures, chronic pain, or functional limitations.

Apply this code when documenting a patient presenting with a current condition directly attributable to a third-degree corrosion of the left thigh that occurred in the past. This is appropriate for follow-up visits addressing the ongoing management of these long-term effects, rather than the initial injury. It should be used when the acute phase of the burn has resolved, but its lasting impact is still being treated.

• Always use in conjunction with an external cause code (V00-Y99) to describe the circumstances of the original corrosion.
• This code is for sequelae only; do not use for active, healing third-degree burns.
• Ensure documentation clearly links the current condition to the past third-degree corrosion of the left thigh.
