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

ICD10CM code

#### 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
