S60.423S Blister (nonthermal) of left middle finger, sequela

Name of the Condition

• Common Name: Blister (nonthermal) of left middle finger, sequela
• Medical Term: Nonthermal blister of left middle finger, sequela

Summary

A nonthermal blister of the left middle finger, sequela, refers to a residual or chronic condition resulting from a previous nonthermal blister injury. It is classified under the ICD-10-CM code S60.423S, indicating it is a sequela (late effect) of a superficial injury to the left middle finger.

Causes

Nonthermal blisters of the left middle finger typically result from friction, pressure, or minor trauma. Sequela may develop if the initial injury heals improperly, leading to persistent skin changes or functional impairment.

Risk Factors

• Delayed or inadequate treatment of the initial blister
• Repeated trauma to the affected area
• Underlying skin conditions (e.g., poor circulation or healing disorders)
• Occupational or recreational activities involving hand use

Symptoms

• Persistent fluid-filled or scarred skin changes
• Reduced sensation or mobility in the left middle finger
• Chronic pain or discomfort in the affected area

Diagnosis

Diagnosis is made through physical examination of the left middle finger, focusing on residual skin changes or functional limitations. Healthcare providers may review the patient’s history of the initial injury to confirm the sequela status.

Treatment Options

• Protective measures: Use of padding or adaptive devices to reduce friction.
• Physical therapy: Exercises to improve mobility and strength.
• Pain management: Topical or oral medications as needed.
• Surgical intervention: Rarely required for severe scarring or functional impairment.

Prognosis and Follow-Up

Prognosis depends on the extent of residual damage. Most cases resolve with conservative management, but follow-up may be needed to monitor healing or address complications. Regular assessments ensure optimal recovery.

Complications

• Chronic pain or stiffness
• Infection of residual skin changes
• Permanent scarring or deformity
• Reduced dexterity or function

Lifestyle & Prevention

• Avoid repetitive friction or pressure on the left middle finger.
• Use protective gear (e.g., gloves) during manual tasks.
• Maintain good skin hygiene to support healing.
• Address underlying conditions that may impair recovery.

When to Seek Professional Help

Seek care if symptoms worsen, signs of infection appear (e.g., redness, pus), or functional limitations persist. Prompt evaluation helps prevent long-term complications.

Tips for Medical Coders

Use code S60.423S for sequela of a nonthermal blister of the left middle finger. Document the relationship to the initial injury and any residual effects to support coding accuracy. Ensure the sequela is clearly linked to the prior event in the medical record.
