ICD-10: S70.329

The ICD-10 code S70.329 refers to a nonthermal blister located on the unspecified thigh. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is essential for accurate diagnosis and management.

Clinical Presentation

Definition of Blisters

Blisters are fluid-filled sacs that form on the skin's surface, typically as a result of friction, pressure, or other forms of irritation. Nonthermal blisters, specifically, are not caused by heat but can arise from various factors, including mechanical injury, allergic reactions, or underlying skin conditions.

Location

The specific designation of the thigh indicates that the blister is located on the upper leg, which can affect mobility and comfort, particularly if the blister is large or painful.

Signs and Symptoms

Common Signs

• Fluid-filled Sac: The primary sign of a blister is the presence of a raised, fluid-filled area on the skin.
• Redness and Swelling: Surrounding the blister, there may be redness and mild swelling, indicating inflammation.
• Intact or Ruptured: Blisters can be intact (still covered by skin) or ruptured, which may expose the underlying skin and increase the risk of infection.

Symptoms

• Pain or Discomfort: Patients often report pain or discomfort, especially when pressure is applied to the area.
• Itching or Burning Sensation: Some individuals may experience itching or a burning sensation around the blister.
• Limited Mobility: Depending on the size and location of the blister, patients may have difficulty moving the affected leg comfortably.
