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

This code signifies a long-term or residual complication resulting from an infection or inflammatory response to a nervous system device, implant, or graft. This includes conditions that persist after the acute phase of the infection or inflammation has resolved, or conditions that are a direct consequence of the initial reaction.

Apply this code when documenting chronic pain, neurological deficits, or structural damage that is a direct sequela of a past infection or inflammatory reaction to a nervous system implant. This is appropriate for conditions that are no longer acute but continue to impact the patient due to the prior complication.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, paralysis).
• Ensure documentation clearly links the current condition to a past infection or inflammatory reaction of a nervous system device.
• Do not use this code for acute infections or inflammatory reactions; those require codes from the T85.73- series without the "S" seventh character.
