Fibrosis due to nervous system prosth dev/grft, sequela

This code signifies a long-term, adverse tissue reaction characterized by the formation of fibrous tissue around or near an implanted nervous system device. This fibrosis is a delayed complication, representing the lasting effects of the body's response to the foreign material.

Use this code when documenting a patient presenting with symptoms or findings directly attributable to fibrotic changes caused by a previously implanted nervous system device, such as a spinal cord stimulator, deep brain stimulator, or nerve graft. This code is appropriate for chronic or residual conditions resulting from the initial adverse reaction.

• Always sequence this code after the code for the specific complication or manifestation of the fibrosis (e.g., pain, neurological deficit).
• Ensure documentation clearly links the fibrosis to the nervous system implant and indicates it is a sequela, not an acute event.
• Consider additional codes for the type of nervous system device (e.g., Z95.0 for cardiac pacemaker) if not already documented.
