T22.7: Corrosion of third degree of shoulder and upper limb, except wrist and hand

Corrosion of the third degree on the shoulder and upper limb, except the wrist and hand, is a severe injury caused by a hazardous substance or chemical. This condition occurs when the corrosive material directly contacts the skin of the upper arm area, causing a deep, full thickness burn. A third degree burn is the most severe type of burn damage as it affects not only the outermost layer of the skin, but also deeper tissue, including nerve endings, sweat glands, and hair follicles. Patients with this condition might experience no pain due to damage to nerve endings, but symptoms may include a dry and leathery texture to the skin, and the skin may appear white, black or visibly charred. This injury necessitates immediate expert medical treatment due to its severe nature that may progress into life-threatening complications if left untreated or if incorrectly managed.
