Brkdwn other nervous sys device, implant or graft, sequela

This code signifies a mechanical failure or malfunction of a nervous system device, implant, or graft, where the patient is experiencing a long-term consequence or complication from this breakdown. It indicates that the initial breakdown event has passed, but its lasting effects are still being addressed.

Use this code when documenting a patient presenting with a chronic issue directly attributable to a previously identified mechanical breakdown of a nervous system implant, such as a vagus nerve stimulator, deep brain stimulator, or spinal cord stimulator. This applies when the focus of the encounter is on managing the sequelae rather than the acute breakdown itself.

• Requires a seventh character "S" for sequela, indicating a complication or condition that arises as a direct result of a previous injury or disease.
• Do not use for acute or initial mechanical breakdowns; those would typically use the appropriate T85.61- code without the "S" or with an "A" or "D" for initial or subsequent encounter.
• Always code the specific sequela or complication first, if known, followed by this code to provide a complete clinical picture.
