S60.42 Blister (nonthermal) of fingers

Name of the Condition

• Common Name: Blister (nonthermal) of fingers
• Medical Term: Nonthermal blister of fingers

Summary

A nonthermal blister of the fingers is a small, fluid-filled pocket that forms on the skin due to friction, pressure, or minor trauma. It is classified under the ICD code S60.42, indicating it affects the fingers but does not involve thermal (heat-related) causes.

Causes

Nonthermal blisters on the fingers are typically caused by repetitive friction or pressure. Common triggers include manual tasks, tight-fitting gloves, or contact with rough surfaces. They may also result from skin reactions to chemicals or irritants.

Risk Factors

• Repetitive hand movements or manual labor
• Poorly fitting gloves or sports equipment
• Allergic reactions to materials or substances
• Prolonged exposure to friction or pressure

Symptoms

• Fluid-filled bump on the skin
• Tenderness or pain around the blister
• Redness or itching in the affected area

Diagnosis

Diagnosis is usually made through physical examination of the affected fingers. Healthcare providers assess the blister’s appearance and may ask about recent activities or exposures to rule out other causes.

Treatment Options

• Protection: Covering with a sterile bandage to prevent further irritation.
• Drainage of the blister under medical advice if painful or persistent.
• Topical antiseptic creams to prevent infection.

Prognosis and Follow-Up

Most nonthermal blisters heal within a few days with proper care. Follow-up may be recommended if the blister becomes infected or does not improve.

Complications

• Infection if the blister ruptures and is not properly cared for
• Scarring in rare cases, especially if the blister is drained improperly

Lifestyle & Prevention

• Wear well-fitting gloves during manual tasks or sports.
• Avoid prolonged friction or pressure on the fingers.
• Use moisturizers to keep the skin hydrated and less prone to blistering.

When to Seek Professional Help

Seek medical attention if the blister shows signs of infection (e.g., pus, increased redness, warmth) or if pain is severe and persistent.

Tips for Medical Coders

When coding for S60.42, ensure documentation specifies the nonthermal nature of the blister and confirms it affects the fingers. Include details about the encounter type (e.g., initial, subsequent) if applicable.
