Burn of third degree of unspecified upper arm, sequela

This code signifies a third-degree burn injury to an unspecified area of the upper arm, where the acute injury has healed, and the patient is now presenting for treatment of a complication or late effect directly resulting from that burn. Third-degree burns involve full-thickness destruction of the skin, often extending into subcutaneous tissue, and heal with significant scarring and potential functional impairment.

Use this code when documenting the long-term consequences or sequelae of a previously sustained third-degree burn to the upper arm. This includes scenarios such as scar contractures, chronic pain, nerve damage, or disfigurement requiring reconstructive surgery, physical therapy, or ongoing management. The original burn event must have occurred in the past, and the current encounter addresses its lasting impact.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., scar contracture, chronic pain).
• Ensure documentation clearly links the current condition to the previous third-degree burn of the upper arm.
• The "S" in the seventh character indicates sequela; do not use this code for the initial or subsequent active treatment of the burn itself.
