Burn of third degree of chest wall, initial encounter

This code signifies a severe burn affecting the full thickness of the skin and underlying tissues on the chest wall. The burn is characterized by destruction of the epidermis, dermis, and often subcutaneous tissue, appearing leathery, charred, or waxy white, with little to no pain sensation due to nerve damage.

Apply this code for patients presenting with a newly diagnosed third-degree burn to the chest wall, including the sternum, ribs, and surrounding soft tissues. This is appropriate for the initial treatment of the burn, such as emergency department visits, initial hospital admissions, or the first encounter with a healthcare provider for this specific injury.

• Ensure documentation clearly specifies "third degree" and the "chest wall" as the burn site.
• Confirm the encounter is for the initial treatment of the burn; subsequent care will require a different encounter character.
• Always code additional burns separately, ensuring laterality and degree are specified for each site.
