Operation Definition

Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part

Procedure Overview

This family involves implanting biological or synthetic material that takes over the physical structure and function of all or part of a cardiovascular structure, using a device recently designated as new technology. A well-known example is a transcatheter aortic valve replacement performed with a next-generation valve system delivered through a catheter rather than open surgery, taking over the role of the patient's diseased native valve. These procedures are typically offered to patients whose anatomy or surgical risk makes the newer device or delivery approach preferable to established alternatives.

The underlying clinical rationale mirrors any replacement procedure: the native structure has failed or degraded to the point that its function must be physically taken over by the substitute material.

Anatomy & Axis Detail

Thoracic Aorta, Arch

The aortic arch is the curved segment of the thoracic aorta that gives rise to the brachiocephalic, left common carotid, and left subclavian arteries, making it one of the most anatomically complex and high-risk regions to repair surgically, traditionally requiring open replacement with hypothermic circulatory arrest. A New Technology Replacement coded to this body part generally reflects a branched or fenestrated endovascular graft designed to exclude an aneurysmal or dissected arch segment while preserving flow to its major branch vessels through a catheter-based delivery system. This approach offers an alternative to open arch surgery for patients at prohibitive surgical risk. Accurate coding depends on confirming that the graft replaces the arch segment itself and maintains perfusion to the arch vessels via its branched components.

Approach: Open

Open approach in New Technology denotes access to the target site through a surgical incision that exposes the body part directly to view and instrumentation. It stands apart from percutaneous and endoscopic approaches, which achieve access through small punctures or existing openings rather than a deliberate surgical opening of tissue.

Device / Substance / Technology: Branched Synthetic Substitute with Intraluminal Device

This value identifies a synthetic vascular graft that includes branches along with an intraluminal device component, typically used in complex aortic repairs requiring both a branched conduit and an internally placed reinforcing element. It differs from a plain branched synthetic substitute by the added intraluminal device, and from simple intraluminal devices by incorporating the branched synthetic graft structure. The combination supports repair of aneurysms involving multiple branch vessels.

Qualifier: New Technology Group 7

As a qualifier value, Group 7 marks a code as belonging to the set of new technologies approved for use in the 2020-2021 fiscal year, a period that included a notable expansion of infectious-disease-related add-on codes. The label does not describe what the technology does; that detail sits in the table and other axis values. It is distinguished from adjoining groups solely by its approval-year cohort.

Coding & Documentation

Coders need documentation identifying the specific replacement device by name, the approach used to deliver it, and confirmation that it physically substitutes for the body part rather than merely reinforcing it. A common error is assigning the standard Cardiovascular section Replacement code when the device actually qualifies for New Technology status, or the reverse, using a New Technology code for a device whose table entry has since been retired or superseded. Coders should also verify the qualifier correctly reflects the number of devices or valve components involved when multiple components are placed in the same session.

Commonly Confused With

This is often confused with Supplement, where the deciding question is whether the material replaces the structure entirely or simply reinforces and augments an existing structure that is left largely in place. It is also distinguished from the standard-section valve or vessel replacement codes purely by the device's inclusion in the New Technology table for the applicable code set year.
