Pain due to nervous system prosth dev/grft, init

This code identifies a patient experiencing pain directly attributable to an implanted or grafted nervous system device, such as a spinal cord stimulator, vagus nerve stimulator, or deep brain stimulator. The pain is a direct consequence of the device itself, not the underlying condition it treats, and the patient is presenting for initial evaluation or treatment of this specific pain.

Use this code when a patient presents with new onset or acute exacerbation of pain localized to the site of a nervous system implant, or radiating from it, and the pain is suspected to be caused by the device. This applies to initial assessments where the cause-and-effect relationship between the device and the pain is being established.

• Always sequence this code first if the pain is the primary reason for the encounter.
• Requires an additional code to specify the type of nervous system device (e.g., Z95.0 for cardiac pacemaker, though this code is for nervous system devices, so a more specific Z-code for nervous system implants would be appropriate if available, or a device-specific complication code).
• Do not use for pain related to the underlying condition for which the device was implanted; this code is specifically for device-related pain.
