ICD-10: T33.51

Superficial frostbite is a cold-related injury that affects the skin and underlying tissues, primarily caused by exposure to freezing temperatures. The ICD-10 code T33.51 specifically refers to superficial frostbite of the wrist. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Superficial Frostbite

Definition

Superficial frostbite occurs when skin and underlying tissues freeze due to prolonged exposure to cold temperatures. It typically affects the extremities, such as fingers, toes, ears, and the face, but can also occur in areas like the wrist. The injury is characterized by the freezing of the epidermis and part of the dermis, leading to potential damage to the skin and soft tissues.

Symptoms

The symptoms of superficial frostbite can vary but generally include:
- Initial Symptoms: The affected area may feel cold and numb. Patients often report a tingling sensation or a burning feeling as the frostbite develops.
- Skin Appearance: The skin may appear pale or waxy, and as the condition progresses, it can take on a blue or purple hue. In some cases, the skin may blister or become red upon rewarming.
- Pain: Once the area begins to thaw, it can become painful, and the affected individual may experience swelling and discomfort.

Diagnosis

Diagnosis of superficial frostbite is primarily clinical, based on the history of cold exposure and the physical examination of the affected area. Medical professionals may assess the extent of the injury by examining the skin's color, temperature, and sensation. Imaging studies are generally not required unless there is suspicion of deeper tissue involvement.
