S60.426S Blister (nonthermal) of right little finger, sequela

Name of the Condition

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

Summary

A nonthermal blister of the right little finger, sequela, refers to a residual or chronic fluid-filled lesion on the skin resulting from prior nonthermal injury. It is classified under the ICD code S60.426S, indicating it is a late effect of a superficial injury to the right little finger.

Causes

Nonthermal blisters of the right little finger, sequela, arise from previous friction, pressure, or minor trauma that caused initial blistering. The sequela represents the persistent or healed state of the original injury, with possible residual tissue changes.

Risk Factors

• History of prior nonthermal injury to the right little finger
• Delayed or incomplete healing of the initial blister
• Underlying skin conditions affecting recovery

Symptoms

• Persistent or recurrent fluid-filled lesion
• Mild tenderness or discomfort in the affected area
• Possible scarring or altered skin texture

Diagnosis

Diagnosis is made through physical examination of the right little finger, focusing on the lesion’s appearance and history of prior injury. Providers assess for signs of residual damage or complications, such as infection or chronic inflammation.

Treatment Options

• Monitoring: Observation for improvement or resolution over time.
• Symptomatic care: Topical treatments to soothe discomfort, if needed.
• Referral: To a specialist if the sequela causes functional impairment or persistent symptoms.

Prognosis and Follow-Up

Prognosis is generally favorable, with most sequelae resolving or stabilizing without intervention. Follow-up may be recommended if symptoms persist or worsen, to rule out complications or guide further management.

Complications

• Chronic pain or sensitivity
• Secondary infection
• Impaired finger mobility or function

Lifestyle & Prevention

• Protect the affected finger from further trauma or friction.
• Use padding or protective gear during activities that may irritate the area.
• Maintain good skin hygiene to support healing.

When to Seek Professional Help

Seek care if the lesion becomes painful, swollen, or shows signs of infection (e.g., redness, pus). Consult a provider if symptoms interfere with daily activities or do not improve over time.

Tips for Medical Coders

Document the sequela status and specify the right little finger. Ensure the code S60.426S is used only for late effects of a nonthermal blister, with clear linkage to the original injury. Include details on lesion persistence or residual changes to support coding accuracy.
