Fibrosis due to nervous system prosth dev/grft, subs

This code describes the development of fibrous tissue around or near an implanted nervous system device, such as a spinal cord stimulator, deep brain stimulator, or nerve stimulator. This fibrosis is a complication of the implant and can potentially interfere with its function or cause other symptoms.

This code is used for follow-up encounters where a patient is being treated for or monitored for fibrosis that has developed as a complication of a previously implanted nervous system device. This includes situations where the fibrosis is causing symptoms, requiring intervention, or being observed for progression.

• Requires an external cause code (e.g., Y70-Y78) to identify the specific device causing the complication.
• Use a more specific code if the fibrosis is causing a mechanical complication (e.g., displacement, erosion).
• This "D" encounter code is for subsequent care after the initial treatment of the fibrosis.
