Mech compl of nervous sys device, implant or graft, init

This code signifies a mechanical issue, not otherwise specified, affecting a nervous system device, implant, or graft. This could involve a malfunction, displacement, or other structural problem with the implanted material. The "initial encounter" designation indicates that the patient is receiving active treatment for this complication.

This code is appropriate for patients presenting with a newly identified mechanical complication of a nervous system device, such as a vagus nerve stimulator, deep brain stimulator, or spinal cord stimulator. It would also apply to complications of nerve grafts or other implanted nervous system materials. Use this code when the specific type of mechanical complication is not detailed in a more specific code.

• Ensure documentation clearly states the complication is mechanical and affects a nervous system device, implant, or graft.
• Verify that this is the first time the patient is being treated for this specific complication.
• If a more specific mechanical complication (e.g., breakage, displacement) is documented, choose the more precise code from the T85.6 subcategory.
