S60.428S Blister (nonthermal) of other finger, sequela

Name of the Condition

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

Summary

A nonthermal blister of other finger, sequela, refers to a residual or chronic condition resulting from a previous nonthermal blister injury to a finger other than the index, middle, ring, or little finger. This sequela may involve persistent skin changes, scarring, or functional limitations following the initial injury.

Causes

Nonthermal blisters of other fingers typically result from friction, pressure, or minor trauma. Sequelae may develop if the initial injury heals improperly, leading to long-term tissue changes such as scarring, altered sensation, or reduced mobility.

Risk Factors

• Delayed or inadequate treatment of the initial blister
• Repeated trauma to the affected area
• Underlying conditions affecting skin healing (e.g., diabetes, vascular disease)
• Poor wound care practices during recovery

Symptoms

• Persistent skin discoloration or scarring
• Reduced range of motion or stiffness in the finger
• Altered sensation (e.g., numbness, tingling)
• Visible or palpable tissue changes at the injury site

Diagnosis

Diagnosis is based on clinical evaluation of the affected finger, including a review of the patient’s history of the initial injury and current symptoms. Healthcare providers assess for signs of chronic tissue damage, such as scarring, contracture, or functional impairment. Imaging or additional tests may be used if deeper structures are involved.

Treatment Options

• Physical therapy to improve mobility and reduce stiffness
• Topical or injectable treatments for scar management
• Occupational therapy to address functional limitations
• Protective measures (e.g., padding, splinting) to prevent further injury

Prognosis and Follow-Up

Prognosis depends on the extent of tissue damage and adherence to treatment. Most sequelae improve with targeted therapy, though some residual changes may persist. Follow-up care focuses on monitoring healing, managing symptoms, and preventing recurrence.

Complications

• Chronic pain or discomfort
• Permanent scarring or deformity
• Reduced dexterity or function
• Increased risk of future injuries to the affected finger

Lifestyle & Prevention

• Use protective gear (e.g., gloves) during manual tasks
• Avoid repetitive friction or pressure on the affected finger
• Maintain good skin hygiene and moisturization
• Seek prompt care for new injuries to prevent complications

When to Seek Professional Help

Consult a healthcare provider if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Early evaluation can help prevent long-term complications.

Tips for Medical Coders

Document the sequela status clearly, including the history of the initial nonthermal blister injury and any residual effects. Ensure the code S60.428S is used only when the condition is a direct result of a prior injury and meets the definition of a sequela. Include details about the affected finger (other than index, middle, ring, or little) and any associated complications in the medical record.
