T22: Burn and corrosion of shoulder and upper limb, except wrist and hand

T22.3: Burn of third degree of shoulder and upper limb, except wrist and hand

Burn of third degree of the shoulder and upper limb, excluding wrist and hand, is a trauma injury that significantly damages all skin layers and underlying tissues of the specified areas. This type of burn is severe and is usually caused by prolonged exposure to extreme heat, chemicals, electricity, or radiation. Symptoms typically include charred, dry, leathery skin which may appear white, brown, or black. The region of injury often demonstrates loss of sensation due to severe nerve damage. As the burn significantly annihilates the protective barrier of the body, it can lead to excessive fluid loss, infection, and systemic shock. A person experiencing a third-degree burn may also encounter difficulty moving the affected limb due to tissue contraction and joint damage. This condition requires immediate medical attention.
