ICD-10: T34.6

Frostbite is a serious medical condition that occurs when skin and underlying tissues freeze due to prolonged exposure to cold temperatures. The ICD-10-CM code T34.6 specifically refers to frostbite with tissue necrosis affecting the hip and thigh. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Frostbite

Definition and Pathophysiology

Frostbite is characterized by the freezing of skin and other tissues, leading to cellular damage. The condition typically occurs in extreme cold, especially when combined with wind chill, wet conditions, or inadequate clothing. The affected areas may initially present with numbness, tingling, and a burning sensation, followed by discoloration and hardening of the skin. As frostbite progresses, it can lead to tissue necrosis, where the affected tissues die due to lack of blood flow and oxygen.

Stages of Frostbite

Frostbite is classified into several stages, which can help in understanding the severity of the condition:

1. Frostnip: The mildest form, causing redness and a cold sensation without permanent damage.
2. Superficial Frostbite: Affects the skin and underlying tissues, leading to swelling and blistering.
3. Deep Frostbite: Involves deeper tissues, including muscles and bones, resulting in significant damage and potential necrosis.

Symptoms

Symptoms of frostbite, particularly in the hip and thigh regions, may include:
- Cold and numb skin: The affected area may feel cold to the touch and numb.
- Color changes: Skin may appear pale, white, or bluish.
- Swelling and blistering: As the condition progresses, blisters may form, and swelling can occur.
- Tissue necrosis: In severe cases, the skin and underlying tissues may die, leading to blackened areas.
