T85.111S Breakdown (mechanical) of implanted electronic neurostimulator of peripheral nerve electrode (lead), sequela

Name of the Condition

• Breakdown (mechanical) of implanted electronic neurostimulator of peripheral nerve electrode (lead), sequela
• ICD Code: T85.111S

Summary

This condition involves the mechanical failure of an implanted electronic neurostimulator, specifically affecting the peripheral nerve electrode (lead). It implies long-term consequences following the initial breakdown, known as a sequela.

Causes

• Wear and tear over time
• Manufacturing defects
• Surgical errors during implantation
• Accidental trauma to the implanted device

Risk Factors

• Use of an implanted neurostimulator
• Previous history of device malfunction
• High-impact physical activities
• Older implant models

Symptoms

• Decreased or irregular stimulation
• Pain at the site of implant
• Numbness or weakness in the affected area
• Possible signs of infection if the device has physically broken

Diagnosis

• Physical examination to assess device function
• Imaging tests like X-rays or MRIs for identifying mechanical issues
• Electrophysiological testing to evaluate nerve function

Treatment Options

• Surgical revision or replacement of the defective component
• Pain management with medications or therapies
• Monitoring and managing any secondary effects or conditions resulting from device failure

Prognosis and Follow-Up

• Prognosis depends on timely intervention and the extent of device failure
• Regular follow-up appointments are essential to monitor the implant and prevent recurrence
• Long-term management might involve lifestyle adjustments to maintain device integrity

Complications

• Chronic pain or discomfort
• Scar tissue formation
• Risk of infection
• Prolonged nerve damage if untreated

Lifestyle & Prevention

• Avoiding high-impact activities that can stress the implant
• Following post-surgery care guidelines meticulously
• Regular check-ups to ensure device functionality

When to Seek Professional Help

• Sudden malfunction or pain in the area of the implant
• Signs of infection like redness, warmth, or swelling
• Any noticeable change in the device's performance

Tips for Medical Coders

• Ensure precise identification of the condition as a sequela, not an initial encounter
• Double-check coding for related complications or conditions
• Be aware of the nuances of coding later-stage device issues as opposed to initial breakdowns
