Burn of third degree of unspecified upper arm, init encntr

This code signifies a full-thickness burn injury affecting an unspecified upper arm. A third-degree burn involves destruction of the epidermis and dermis, extending into subcutaneous tissue, and often presents with a leathery, white, or charred appearance with absent sensation.

Apply this code for initial treatment of a severe burn to the upper arm where the specific side (left or right) is not documented. This includes emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific burn injury.

• Ensure documentation clearly states "third degree" and "upper arm" and that the encounter is the initial treatment for this burn.
• Do not use if the burn is specified as left or right upper arm; instead, select the appropriate laterality code.
• If the burn involves multiple sites or is part of a more extensive burn injury, consider additional codes for those areas.
