Embolism due to nervous system prosth dev/grft, sequela

This code signifies a long-term complication where an embolism has occurred as a direct result of a previously implanted nervous system prosthetic device, implant, or graft. It indicates that the embolism is a residual effect or late consequence of the initial device.

This code is appropriate for documenting a patient presenting with an embolism that is definitively linked to a past nervous system device, even if the device has since been removed. It should be used when the embolism is no longer an acute event but rather a persistent or late-onset problem stemming from the device.

• Requires a definitive causal link between the nervous system device and the embolism.
• The "S" seventh character indicates a sequela, meaning it's used for complications or conditions that are the late effects of an earlier problem.
• Always sequence this code after the code for the specific type of embolism, if applicable, to provide full clinical context.
