T29-T32: Burns and corrosions of multiple and unspecified body regions

T31: Burns classified according to extent of body surface involved

Burns classified according to the extent of body surface involved, also known as T31 in the ICD-10 WHO 2016 classification, encompass a range of burn injuries that vary in severity based on the size of the area affected on the patient's body. These injuries usually occur as a result of exposure to extreme heat, electricity, chemicals, or radiation. Initial symptoms typically include pain, reddened skin, and blistering, with severity and symptoms varying depending on the extent of body surface involved. In more severe cases, when a larger percentage of the body is affected, symptoms may progress to alter the function of the heart, lungs, and kidneys, potentially leading to shock or even death. The depth of the burn, the location on the body, and the patient's age and general health also play a significant role in the course of the disease. The extent of the body surface involved in the burn also impacts the types of treatment options available and the possible long-term outcomes for the patient.
