Corrosion of third degree of right knee, sequela

This code signifies the long-term effects or complications resulting from a full-thickness burn (third degree) that specifically affected the right knee. These sequelae can include scarring, contractures, chronic pain, or functional limitations that persist after the initial injury has healed.

Apply this code when documenting a patient presenting with a current condition directly attributable to a third-degree corrosion of the right knee that occurred in the past. This is appropriate for follow-up visits addressing the chronic consequences of such an injury, rather than the acute burn itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the previous third-degree corrosion of the right knee.
• Verify the laterality (right knee) is explicitly stated in the medical record.
