Fibrosis due to nervous system prosth dev/grft, init

This code signifies the development of fibrous tissue as a complication directly attributed to a prosthetic device, implant, or graft within the nervous system. This fibrotic reaction can impair device function or cause neurological symptoms due to compression or irritation. It represents the initial presentation of this specific complication.

Apply this code when a patient presents with new or worsening symptoms, and diagnostic imaging or surgical findings confirm the presence of fibrosis around a nervous system implant (e.g., spinal cord stimulator, deep brain stimulator, shunt). This is appropriate for the first encounter where this specific complication is documented and treated.

• Ensure documentation clearly links the fibrosis to the nervous system device and specifies it as the initial encounter for this complication.
• Do not use for fibrosis unrelated to a prosthetic device or for fibrosis in other body systems.
• Consider additional codes for specific neurological symptoms or device malfunction if present.
