Operation Definition
Taking over a portion of a physiological function by extracorporeal means
Procedure Overview
This family covers temporary mechanical circulatory support devices that take over a portion of the heart's pumping function from outside the body, used when a patient's own heart can't adequately maintain blood flow on its own. Typical scenarios include cardiogenic shock, a heart attack complicated by pump failure, or high-risk procedures like complex angioplasty where a patient needs hemodynamic backup while the underlying problem is treated or the heart recovers.
Unlike devices that fully replace heart function, these systems are designed to assist rather than substitute for the heart entirely, buying time for recovery, bridging a patient to a more definitive treatment, or supporting them through a procedure that would otherwise put too much strain on a failing heart.
Anatomy & Axis Detail
Internal Carotid Artery, Right
The right internal carotid artery is the direct continuation supplying the right anterior cerebral circulation and has no branches in the neck, making any debris entering it particularly consequential for stroke risk. Assistance applied to this vessel typically represents temporary cerebral flow protection or augmentation used in conjunction with an endovascular procedure elsewhere in the carotid system, such as reversing or diverting flow so embolic material cannot travel intracranially while a stent or other device is deployed nearby. The support is transient and reversible, established through a catheter or sheath rather than an implant, and its use is closely tied to procedures performed on the adjacent common or external carotid segments.
Approach: Percutaneous
In New Technology, Percutaneous describes entry into the body via needle or instrument puncture through the skin or a mucous membrane, without a surgical incision, mirroring the same concept in Medical and Surgical. It is distinguished from Open access, which requires a full incision, and from Percutaneous Endoscopic, which adds visualization through the puncture site.
Device / Substance / Technology: Cerebral Embolic Filtration, Single Integrated Distal Filter
This device value identifies embolic protection technology consisting of a single filter positioned to capture debris traveling toward the cerebral circulation, most often used during transcatheter aortic valve procedures. Its defining feature is a single, integrated filter design rather than a dual-filter arrangement that separately protects multiple aortic arch vessels. The distinction affects which and how many downstream vessels receive direct filtration coverage.
Qualifier: New Technology Group 11
This qualifier designates Group 11, the most recent cohort at the time of its introduction, grouping technologies newly approved for New Technology section reporting in that fiscal year. Like every group value in this axis, it functions as an administrative marker rather than a description of the clinical intervention, which is captured elsewhere in the code. Its main point of confusion is with Group 10, the immediately preceding annual release.
Coding & Documentation
Accurate coding requires the record to specify the exact device and its qualifier, since different circulatory assist devices are distinguished by design and the way they interact with the heart's own output. Duration of support and the vessel or chamber accessed for device placement also matter for complete documentation. A frequent mistake is coding this as Performance, which applies when a device completely takes over a function, rather than Assistance, which applies when the device supplements a heart that is still contributing some of its own pumping.
Commonly Confused With
This family is commonly confused with Performance procedures such as cardiopulmonary bypass, where the device fully replaces cardiac or respiratory function rather than assisting it. The distinction turns on whether the native heart continues to contribute to circulation alongside the device, which points to Assistance, or whether the device has completely taken over, which points to Performance.
