I/I react d/t other nrv sys device, implnt or graft, subs

This code signifies an infection or inflammatory response occurring in a patient due to a previously implanted nervous system device, implant, or graft. This reaction is not the initial presentation but rather a follow-up encounter for ongoing management or treatment of the complication. It indicates a localized or systemic adverse reaction to the foreign body within the nervous system.

Use this code when a patient presents for continued care of an infection or inflammatory process related to a nervous system device (e.g., vagus nerve stimulator, deep brain stimulator, spinal cord stimulator, intracranial shunt) after the initial treatment has begun. This applies to subsequent visits for antibiotic therapy, wound care, monitoring, or evaluation of the ongoing complication. It would also be appropriate for follow-up after surgical intervention for the infection or inflammation.

• Requires an additional code to identify the specific infection, if applicable.
• Do not use for the initial encounter of the complication; a different seventh character would be appropriate.
• Ensure documentation clearly specifies the "subsequent encounter" for the ongoing management of the infection/inflammation.
