S60.420 Blister (nonthermal) of right index finger

Name of the Condition

• Common Name: Blister on the right index finger
• Medical Term: Nonthermal blister of right index finger

Summary

A nonthermal blister of the right index finger is a fluid-filled pocket on the skin resulting from friction, pressure, or minor trauma. It is classified under the ICD code S60.420, indicating it is a specific superficial injury to the right index finger.

Causes

Nonthermal blisters on the right index finger 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 right index 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 the blister is painful or persistent.
• Topical antiseptic creams to reduce infection risk.

Prognosis and Follow-Up

Most nonthermal blisters heal within 1–2 weeks with proper care. Follow-up may be recommended if symptoms worsen or if infection signs (e.g., pus, increased redness) develop.

Complications

• Infection if the blister ruptures and is not properly cared for.
• Delayed healing due to repeated friction or pressure.
• Scarring in rare cases, especially if the blister is large or deep.

Lifestyle & Prevention

• Wear well-fitting gloves during manual tasks.
• Avoid tight or restrictive items on the right index finger.
• Use moisturizers to keep skin hydrated and reduce friction.
• Take breaks during repetitive activities to minimize pressure.

When to Seek Professional Help

Seek medical attention if the blister shows signs of infection (e.g., pus, fever), is extremely painful, or does not improve after 1–2 weeks of home care.

Tips for Medical Coders

Document the specific location (right index finger) and nature of the blister (nonthermal) to support accurate coding. Ensure the encounter type and any additional details (e.g., initial vs. subsequent) are clearly recorded for proper code assignment.
