In code Table X2C, New Technology, Cardiovascular System, Extirpation, new codes were created to identify the extirpation of matter from the arterial and venous systems using a computer-aided mechanical thrombectomy aspiration device as shown below.

The procedure uses mechanical aspiration thrombectomy via the Indigo® System to treat occlusions in a non-coronary or non-intracranial artery or vein, or in an arterial bypass graft. Via vascular access (typically the femoral vein), the catheter is manipulated to the clot under imaging guidance, including through the heart to the pulmonary arteries. Once the clot is reached, the Lightning™ component of the Indigo® System is turned on and the thrombus is removed using aspiration rather than mechanical force as in conventional thrombectomies.
The Lightning™ component also has sensors that detect whether the device is in thrombus or blood and only turns on suction when in thrombus. Since aspiration rather than mechanical force is used to remove the thrombus, it does not rely on a large intravascular device to capture the clot and does not need to be repeatedly placed into and removed from the body for adequate thrombus removal.
