Electronic analysis of implanted neurostimulator pulse generator system (eg, rate, pulse amplitude and duration, battery status, electrode selectability and polarity, impedance and patient compliance measurements), complex deep brain neurostimulator pulse
CPT4 code
Name of the Procedure:
Electronic Analysis of Implanted Neurostimulator Pulse Generator System, Complex Deep Brain Neurostimulator Pulse
Summary
In simple terms, this procedure involves checking and fine-tuning the settings of a device implanted in the brain that sends electrical signals to help control certain medical conditions. This includes adjusting and assessing the device's rate, pulse strength, battery status, and other technical details.
Purpose
This procedure is used to manage and treat conditions like Parkinson's disease, essential tremor, and dystonia by ensuring the neurostimulator device is working correctly. The goal is to optimize its performance to improve the patient's symptoms and quality of life.
Indications
- Patients with Parkinson's disease, essential tremor, dystonia, or other neurological conditions.
- Individuals showing signs that their implanted device needs adjustment, such as exacerbation of symptoms.
- Regular maintenance check to ensure device functionality and battery life.
Preparation
- Patients may need to fast for a short period before the procedure.
- All current medications should be discussed with the healthcare provider, as some may need to be adjusted.
- Routine diagnostic tests like blood work or imaging might be required.
Procedure Description
- The patient arrives at the setting (hospital, clinic).
- The area around the implant is cleaned and sterilized.
- A specialized programmer device is used to communicate with the neurostimulator.
- Settings such as pulse rate, amplitude, duration, and electrode polarity are checked and adjusted as needed.
- Battery status and impedance measurements are verified to ensure the device and its connections are functioning correctly.
- Patient feedback is often collected to tailor the settings to improve symptom control.
Tools Used:
- Neurostimulator programmer device
- Sterile field setup
Anesthesia:
- Usually, no anesthesia or mild sedation might be required, based on patient needs and comfort.
Duration
The procedure typically takes about 30 minutes to an hour.
Setting
This procedure is usually performed in a hospital, outpatient clinic, or a specialized neurostimulation center.
Personnel
- Neurologist or neurosurgeon
- Specialized technician or nurse
- Possibly an anesthesiologist or nurse anesthetist if sedation is used
Risks and Complications
- Infection at the site of the device
- Discomfort or pain during adjustments
- Temporary worsening of symptoms until optimal settings are found
- Rare malfunction of the neurostimulator
Benefits
- Improved management of symptoms from neurological conditions
- Enhanced quality of life
- Immediate feedback and adjustment for better symptom control
- Prolonged battery life through efficient settings management
Recovery
- Most patients can resume normal activities immediately after the procedure.
- Follow-up appointments may be scheduled to further fine-tune settings.
- Instructions on monitoring device function and recognizing any issues will be provided.
Alternatives
- Medication adjustments
- Physical therapy
- Other forms of neurosurgical intervention like lesioning procedures
- Each alternative has its own set of benefits and limitations; the neurostimulator offers targeted and adjustable symptom control with real-time feedback.
Patient Experience
- Some minor discomfort or pressure at the implant site during adjustments.
- Possible brief periods of increased symptoms as settings are optimized.
- Pain management including over-the-counter pain relief can be used if needed.
