Percutaneous insertion of a permanent embolic protection device into the common carotid artery

This code describes the minimally invasive insertion of a device into the common carotid artery to prevent embolic material (e.g., plaque fragments) from traveling to the brain during an endovascular procedure. This protective measure aims to reduce the risk of stroke or transient ischemic attack (TIA) during interventions like carotid artery stenting.

This code is used when a permanent embolic protection device is percutaneously deployed in the common carotid artery. Documentation should clearly indicate the placement of a permanent device, the vessel (common carotid), and the percutaneous approach, typically in conjunction with other carotid interventional procedures.

• Ensure documentation specifies "permanent" device placement; temporary devices are coded differently.
• This code is typically reported in conjunction with the primary carotid interventional procedure (e.g., carotid artery stenting).
• Verify the device is placed in the common carotid artery, as protection in other vessels would not be reported with this code.
