Burn of third degree of left upper arm, sequela

This code signifies a third-degree burn affecting the left upper arm, indicating full-thickness skin destruction extending through the epidermis and dermis, and potentially into underlying tissues. The "S" seventh character denotes that this encounter is for the sequela (late effects) of the burn, meaning the patient is being treated for complications or conditions arising from the original burn injury after the acute phase has passed.

This code is appropriate when a patient presents for treatment of long-term complications directly resulting from a third-degree burn to their left upper arm. Examples include scar contractures, chronic pain, nerve damage, or other persistent issues that developed as a consequence of the initial burn. It should not be used for the initial treatment of the acute burn.

• Always ensure the documentation clearly links the current condition to the previous third-degree burn of the left upper arm.
• Do not use this code for initial or subsequent encounters for the active burn wound; those require different seventh characters.
• Code any specific sequelae (e.g., scar contracture, chronic pain) in addition to this code to provide a complete clinical picture.
