Brkdwn implanted electrnc stimulator of nervous sys, sequela

This code signifies a mechanical failure or malfunction of an implanted electronic stimulator device, other than a cardiac device, that is used to stimulate the nervous system. This breakdown is a long-term consequence or complication of the initial device implantation. Examples include issues with spinal cord stimulators, deep brain stimulators, or vagus nerve stimulators.

Use this code when documenting a patient presenting with symptoms directly attributable to a mechanical breakdown of their previously implanted nervous system stimulator. This applies to situations where the device itself has physically failed, such as lead fracture, battery casing breach, or internal component damage, and this issue is a sequela of the original implantation. It is appropriate for follow-up encounters addressing these chronic device complications.

• Always sequence this code after the primary diagnosis indicating the reason for the original stimulator implantation, if applicable.
• Ensure documentation clearly specifies the "mechanical breakdown" and that it's an "other" nervous system stimulator, not a cardiac device.
• This "S" seventh character indicates a sequela, meaning the complication is a late effect or residual condition of the initial problem.
