T31.91
Burns involving 90% or more of body surface with 10-19% third degree burns
Clinical Classification Guidelines
Medical Intelligence & Overview
Burn injuries can vary greatly in severity, from minor superficial burns to extensive, life-threatening injuries. The ICD-10 code T31.91 specifically describes a severe form of burn injury involving 90% or more of the body surface, with 10-19% of the affected area being third-degree burns. Third-degree burns are the most serious, damaging all layers of the skin and potentially deeper tissues. Such extensive burns require immediate and specialized medical care to manage the injuries and prevent complications.
Causes & Symptoms
Clinical Causes: Thermal burns from fire, hot liquids, or steam Chemical burns from corrosive substances Electrical burns from high-voltage injuries Radiation burns from exposure to intense radiation sources Accidents involving explosions or industrial equipment
Key Symptoms: Extensive areas of charred, white, or leathery skin Severe pain or insensitivity in the burned areas due to nerve damage Swelling and blistering over large skin areas Presence of deep tissue damage with potential exposure of underlying tissues Signs of shock, such as pallor, rapid heartbeat, and low blood pressure Loss of skin function, including temperature regulation and infection barrier
Diagnostic & Treatment
Diagnosis Path: The diagnosis of extensive burns with significant third-degree involvement involves a thorough clinical evaluation by trauma or burn specialists. This includes visual assessment of burn depth and extent using the "rule of nines" or more advanced methods like the Lund-Browder chart to estimate total body surface area (TBSA) affected. Imaging studies or biopsies may be used to determine the depth of burns where necessary. Immediate assessment also includes monitoring for signs of shock and other complications.
Treatment Protocols: Treatment for extensive burns with major third-degree involvement is complex and typically requires hospitalization in a specialized burn unit. Key components of care include:
