Burn of third degree of left thumb (nail), initial encounter

This code signifies a full-thickness burn affecting the left thumb, including the nailbed. A third-degree burn involves destruction of the epidermis and dermis, extending into subcutaneous tissue, and typically presents with a leathery, charred, or waxy white appearance. Nerve endings are often destroyed, leading to a lack of sensation in the affected area.

Apply this code when documenting the initial treatment or evaluation of a patient presenting with a third-degree burn specifically located on their left thumb. This includes situations such as initial emergency department visits, first clinic appointments for the burn, or the initial hospital admission for burn care.

• Ensure the documentation clearly specifies the left thumb and the depth as third-degree.
• Verify that this is the patient's first encounter for this specific burn injury.
• Do not use for burns of other degrees, other fingers, or subsequent encounters for the same burn.
