ICD-10: S70.221

The ICD-10 code S70.221 refers to a blister (nonthermal) located on the right hip, specifically during the initial encounter. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is essential for accurate diagnosis and treatment.

Clinical Presentation

Definition of Blister

A blister is a small pocket of fluid that forms between the upper layers of the skin, often as a result of friction, pressure, or irritation. Nonthermal blisters are those that do not arise from burns or heat exposure but rather from mechanical causes or other non-thermal factors.

Common Causes

• Friction: Repeated rubbing against the skin, often seen in athletes or individuals wearing ill-fitting clothing or footwear.
• Pressure: Prolonged pressure on a specific area, which can occur in patients with limited mobility or those who sit for extended periods.
• Allergic Reactions: Contact dermatitis from allergens can lead to blister formation.
• Infections: Certain skin infections can also result in blistering.

Signs and Symptoms

Localized Symptoms

• Fluid-Filled Lesion: The primary sign is the presence of a fluid-filled blister on the right hip, which may vary in size.
• Redness and Swelling: Surrounding skin may appear red and swollen due to inflammation.
• Pain or Discomfort: Patients often report pain or tenderness in the area, especially when pressure is applied.
• Itching: Some patients may experience itching around the blister, particularly if it is related to an allergic reaction.

Systemic Symptoms

In most cases of nonthermal blisters, systemic symptoms are minimal. However, if the blister is due to an underlying infection or severe allergic reaction, patients may experience:
- Fever: Indicating a possible infection.
- Malaise: General feelings of discomfort or illness.

Patient Characteristics

Demographics

• Age: Blisters can occur in individuals of all ages, but certain populations, such as the elderly or those with compromised skin integrity, may be more susceptible.
• Activity Level: Active individuals, particularly athletes, are at higher risk due to increased friction and pressure on the skin.

Health Status

• Skin Conditions: Patients with pre-existing skin conditions (e.g., eczema, psoriasis) may be more prone to blister formation.
