S60.428D Blister (nonthermal) of other finger, subsequent encounter

Name of the Condition

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

Summary

A nonthermal blister of other finger, subsequent encounter, refers to a fluid-filled pocket on the skin that develops due to friction, pressure, or minor trauma, occurring during a follow-up visit for a previously diagnosed injury. This code indicates the condition is being managed after the initial encounter and is classified under ICD-10-CM S60.428D.

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 antibiotics if infection is a concern.
• Pain management 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 to monitor healing, especially if the blister is large, infected, or slow to resolve. Avoiding the initial cause of the blister can prevent recurrence.

Complications

• Infection, particularly if the blister ruptures or is drained improperly.
• Scarring, especially if the blister is deep or becomes infected.
• Delayed healing due to persistent friction or pressure.

Lifestyle & Prevention

• Wear well-fitting gloves during manual tasks or activities involving friction.
• Use moisturizers to keep skin supple and reduce friction.
• Avoid tight or restrictive accessories that may cause pressure.
• Take breaks during repetitive hand activities to reduce strain.

When to Seek Professional Help

Seek medical attention if the blister shows signs of infection (e.g., pus, increased redness, warmth), is extremely painful, or does not improve after a week of home care. Also, consult a provider if the blister recurs frequently or affects daily function.

Tips for Medical Coders

Use S60.428D for a nonthermal blister of other finger during a subsequent encounter. Ensure documentation specifies the finger (other than index, middle, ring, or little) and confirms the encounter is for follow-up care. Note any complications or treatments provided to support accurate coding.
