Electronic analysis of implanted neurostimulator pulse generator system (eg, rate, pulse amplitude and duration, configuration of wave form, battery status, electrode selectability, output modulation, cycling, impedance and patient measurements) gastric n
CPT4 code
Name of the Procedure:
Electronic analysis of implanted neurostimulator pulse generator system (e.g., rate, pulse amplitude and duration, configuration of waveform, battery status, electrode selectability, output modulation, cycling, impedance and patient measurements) gastric n.
Summary
This procedure involves examining an implanted neurostimulator's settings and functionality to ensure it is operating correctly. The neurostimulator is a device that sends electrical impulses to the gastric nerve, which can help manage certain gastrointestinal issues.
Purpose
The procedure aims to diagnose issues with the neurostimulator and optimize its settings. This helps manage symptoms of gastrointestinal conditions, such as gastroparesis, by ensuring the device is delivering the correct electrical stimulation.
Indications
- Persistent symptoms of gastroparesis (e.g., nausea, vomiting, bloating).
- Patients who have a neurostimulator implanted that requires routine checks or adjustments.
- Symptoms indicating potential device malfunction (e.g., no symptom relief, abnormal sensations).
Preparation
- Patients may be advised to fast for a few hours before the procedure.
- Inform the healthcare provider of any medications being taken; some adjustments might be necessary.
- Pre-procedure diagnostic tests (e.g., imaging or blood tests) might be required to evaluate the patient’s condition.
Procedure Description
- The patient lies down in a comfortable position.
- The healthcare provider uses a specialized programmer to communicate with the implanted neurostimulator.
- Various parameters such as rate, pulse amplitude, and waveform configuration are evaluated and adjusted if necessary.
- Battery status and electrode selectability are checked to ensure optimal functionality.
- Patient measurements, like impedance, are taken to assess the effectiveness of the stimulation.
- The entire process is monitored, and real-time adjustments are made based on patient feedback and diagnostics.
Duration
The procedure typically takes around 30 to 60 minutes.
Setting
The procedure is usually performed in an outpatient clinic or hospital setting.
Personnel
- A specialized healthcare provider, such as a neurologist or gastroenterologist.
- A nurse for assistance and patient care.
- An anesthesiologist, if sedation is required (though usually not necessary).
Risks and Complications
- Minor discomfort during the adjustment
- Rare risk of infection at the site of the neurostimulator
- Potential for temporary worsening of symptoms if settings are not optimized
Benefits
- Improved symptom management for gastroparesis or other gastrointestinal conditions
- Enhanced quality of life due to better control of symptoms
- Immediate feedback on device performance and necessary adjustments
Recovery
- Minimal recovery time; patients can usually resume normal activities immediately after the procedure.
- Patients should follow any specific instructions provided by their healthcare provider concerning activity, diet, and medications.
- Follow-up appointments as necessary to monitor the device and symptom improvement.
Alternatives
- Dietary changes and medications specific to managing gastrointestinal symptoms.
- Surgical alternatives, such as gastric bypass surgery.
- Each alternative has its own pros and cons in terms of invasiveness, recovery time, and effectiveness.
Patient Experience
- Patients might feel slight discomfort during adjustments but generally do not experience pain.
- Post-procedure, patients might feel the improved efficacy of symptom management almost immediately.
- Pain management and comfort measures are usually minimal due to the non-invasive nature of the procedure.
