Burn of second degree of left knee, sequela

This code signifies a second-degree burn affecting the left knee, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly resulting from that burn. This could include issues like scar contracture, chronic pain, or non-healing ulcers at the burn site.

Apply this code when a patient is seen for a long-term effect or complication of a previously sustained second-degree burn to the left knee. This is appropriate for follow-up care related to the burn's aftermath, such as scar revision surgery or management of persistent functional limitations.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to the prior second-degree burn of the left knee.
• Do not use this code for the initial treatment of an acute burn; the "S" seventh character indicates sequela.
