S60.428 Blister (nonthermal) of other finger

Name of the Condition

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

Summary

A nonthermal blister of other finger is a fluid-filled pocket on the skin resulting from friction, pressure, or minor trauma. It is classified under the ICD code S60.428, indicating it is a specific superficial injury to a finger other than the index, middle, ring, or little finger.

Causes

Nonthermal blisters on other 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 irritants or minor trauma.

Risk Factors

• Repetitive hand movements or manual labor
• Poorly fitting gloves or accessories
• Exposure to abrasive materials or chemicals
• Participation in activities with frequent hand use

Symptoms

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

Diagnosis

Diagnosis is typically made through physical examination of the affected finger. Healthcare providers assess the blister’s appearance, size, and surrounding tissue. Imaging is rarely needed unless deeper tissue damage or infection is suspected.

Treatment Options

• Protection: Covering with a sterile bandage to prevent further irritation.
• Drainage under medical advice if painful or persistent.
• Topical antiseptics to reduce infection risk.
• Pain relief with over-the-counter analgesics if needed.

Prognosis and Follow-Up

Most nonthermal blisters heal within 1–2 weeks with proper care. Follow-up may be recommended if symptoms worsen, signs of infection develop, or the blister does not improve.

Complications

• Infection, particularly if the blister ruptures and is exposed to bacteria.
• Delayed healing due to repeated friction or pressure.
• Scarring in rare cases, especially if the blister is drained improperly.

Lifestyle & Prevention

• Wear well-fitting gloves during manual tasks or sports.
• Avoid prolonged contact with rough or abrasive surfaces.
• Use moisturizers to keep skin supple and reduce friction.
• Take breaks during repetitive hand activities to minimize pressure.

When to Seek Professional Help

Seek medical attention if the blister shows signs of infection (e.g., pus, increased redness, warmth), if pain is severe, or if the blister does not heal within two weeks.

Tips for Medical Coders

Use code S60.428 for nonthermal blisters of fingers other than the index, middle, ring, or little finger. Ensure documentation specifies the affected finger (e.g., thumb, pinky) to support accurate coding.
