Name of the Procedure:

• Common Name: Power Wheelchair Controller Replacement
• Technical/Medical Term: Expandable Power Wheelchair Controller Replacement (HCPCS Code E2376)

Summary

A power wheelchair controller replacement involves installing an updated, expandable control system along with the necessary electronics and mounting hardware in a power wheelchair. This procedure is typically done when the current controller is outdated or malfunctioning and needs replacement to ensure safe and effective operation of the wheelchair.

Purpose

The primary purpose of replacing the power wheelchair controller is to restore or improve the functionality of the power wheelchair. It addresses issues such as unresponsive controls, decreased maneuverability, and outdated technology that may compromise the safety and effectiveness of the wheelchair.

Indications

• Symptoms or Conditions: Malfunctions in the power wheelchair controls, unresponsive or erratic behavior, outdated control systems.
• Patient Criteria: Users of power wheelchairs who experience control issues that cannot be resolved through repairs or software updates. Patients requiring advanced control features due to their specific medical conditions.

Preparation

• Pre-Procedure Instructions:

  • Ensure the wheelchair battery is fully charged.
  • Inform the technician of any recent problems.
  • Review the replacement procedure with the service provider.

• Diagnostic Tests:

  • An assessment of the existing wheelchair to identify specific issues with the current controller.
  • Possible software diagnostics to confirm the problem.

Procedure Description

1. The wheelchair is safely positioned and powered down.
2. The old controller and its hardware are carefully removed.
3. The new expandable controller, along with the necessary electronics and mounting hardware, are installed.
4. The system is connected and calibrated according to manufacturer specifications.
5. A series of tests are performed to ensure all functions are operating correctly.
6. Adjustments are made for user-specific settings.

Duration

Typically, the procedure takes about 1-2 hours, depending on the complexity of the installation and any necessary calibrations.

Setting

The procedure is generally performed in a mobility service center, a specialized wheelchair service clinic, or an outpatient medical facility with appropriate resources.

Personnel

• Mobility service technician or specialist
• Occupational therapist (optional, for settings adjustment)
• Medical technician (if in a clinical setting)

Risks and Complications

• Risks: Electrical faults if not installed correctly, potential for improper calibration leading to poor performance.
• Complications: Rare but may include temporary loss of mobility during the replacement procedure, need for additional adjustments post-installation.

Benefits

• Restored or improved mobility and control of the wheelchair.
• Enhanced safety and reliability with updated technology.
• Customizable control options to better meet the user's needs.

Expected benefits can often be realized immediately after the procedure, though some fine-tuning may be necessary in the following days.

Recovery

• Post-Procedure Care:

  • Monitor the wheelchair's performance.
  • Report any issues to the service provider immediately.

• Recovery Time: No physical recovery time is needed, but users may need to spend a short period re-familiarizing themselves with the new control system.

• Follow-Up: A follow-up appointment may be scheduled to check on the system's performance and make any needed adjustments.

Alternatives

• Repairing the existing controller, if possible.
• Using a different model or type of wheelchair, potentially with other control systems.

Pros of Alternatives:

• Potentially lower cost for repairs.
• Switching wheelchairs might offer advanced features not available with current equipment.

Cons of Alternatives:

• Repairs may not be an option if the controller is obsolete or too damaged.
• Acquiring a new wheelchair involves higher costs and possibly longer adaptation times.

Patient Experience

During the procedure, patients usually wait while the technician performs the replacement. Post-procedure, they might experience a learning curve with the new controller but should receive training and support from the mobility service provider. Pain is not typically a concern in this procedure, as it's a non-invasive equipment replacement. Comfort measures include ensuring the new controller is adjusted to the patient's ergonomic needs.
