Embolism due to nervous system prosth dev/grft, init

This code signifies the formation of an embolus (a blood clot or other foreign material) that has originated from a prosthetic device, implant, or graft within the nervous system. This complication can lead to various neurological deficits depending on the location and size of the embolus, potentially causing ischemia or infarction.

Use this code when a patient presents with an embolism directly attributable to a nervous system device, such as a shunt, deep brain stimulator lead, or intracranial stent. This code is appropriate for the initial encounter where the embolism is first diagnosed and treatment for the acute event is initiated.

• Ensure documentation clearly links the embolism to the nervous system device.
• Confirm this is the initial encounter for the treatment of the embolism. Subsequent encounters would require a different seventh character.
• Code any associated neurological deficits or conditions caused by the embolism separately.
