Burn of third degree of unspecified lower leg, sequela

This code signifies a third-degree burn on an unspecified part of the lower leg, indicating full-thickness tissue destruction. It is used to report the long-term effects or complications arising from such a burn, rather than the acute injury itself.

Apply this code when documenting conditions that are residual effects of a previously sustained third-degree burn to the lower leg. Examples include chronic pain, scarring, contractures, or functional limitations directly attributable to the past burn injury. This code is appropriate for follow-up visits addressing these lasting consequences.

• Always use a seventh character of 'S' for sequela when reporting the long-term effects of a burn.
• Code the specific sequela (e.g., scar, contracture) first, then use this code as a secondary diagnosis to indicate the cause.
• Ensure documentation clearly links the current condition to the previous third-degree burn of the lower leg.
