Presence of neurostimulator

This code indicates that a patient has an implanted device designed to stimulate nerves, such as a spinal cord stimulator, deep brain stimulator, or vagus nerve stimulator. These devices deliver electrical impulses to specific areas of the nervous system to manage various conditions.

Use this code when documenting the presence of any type of neurostimulator, regardless of the reason for its implantation or its current functional status. It is typically used as a secondary diagnosis to provide a complete picture of the patient's medical history and current device status.

• Always code this as a secondary diagnosis; it never stands alone as the primary reason for an encounter.
• Specify the type of neurostimulator with additional codes if more detail is required and available (e.g., Z95.0 for cardiac pacemaker, though not a neurostimulator, illustrates the principle of specificity).
• Do not use this code for external neurostimulation devices.
