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
Replacement procedures take out a diseased or damaged segment of an upper artery and put in biological or synthetic material, such as a graft, to physically stand in for the tissue that was removed. This differs from simply patching or reinforcing a vessel, since Replacement involves substituting material that takes over both the structure and function of the artery segment that's gone.
This approach is used when a section of artery, in the subclavian, axillary, brachial, or related upper-extremity vessels, is too diseased, aneurysmal, or damaged to be safely repaired and left in place. A synthetic graft, a segment of the patient's own vein, or donor tissue is sewn in to reconnect the artery and restore blood flow through that portion of the limb or upper body.
Replacement is a more involved undertaking than a straightforward repair, since it typically requires removing the compromised segment of vessel first before positioning and securing the substitute material in its place.
Anatomy & Axis Detail
Common Carotid Artery, Left
On the left side of the neck, the common carotid artery arises directly from the aortic arch rather than the brachiocephalic trunk, giving it a slightly longer intrathoracic course before it becomes accessible in the neck. Replacement is undertaken for advanced atherosclerotic occlusive disease, aneurysm, dissection, or oncologic resection involving the vessel wall, most often using a synthetic or autologous graft anastomosed proximally and distally to healthy artery. Because this vessel's origin is closer to the mediastinum, proximal disease occasionally requires a more extensive surgical exposure than on the right. Surgeons must also protect the adjacent vagus nerve and jugular vein during dissection, and accurate documentation of the graft type and the extent of arterial segment replaced supports precise coding of the procedure.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Autologous Tissue Substitute
Autologous Tissue Substitute identifies a device value where material harvested from the patient's own body, such as an autograft, is used to replace or reconstruct a body part. Its defining feature is tissue origin from the patient, setting it apart from Nonautologous Tissue Substitute, sourced from a donor or animal, and Synthetic Substitute, made of manufactured material.
Coding & Documentation
Coders assign Replacement when documentation shows a segment of artery was excised or otherwise taken out and a graft, whether autologous vein, synthetic conduit, or donor tissue, was placed to take over that segment's function. The device value must reflect the specific material used, and the note should make clear that the graft is replacing removed tissue rather than being layered onto tissue that remains in place.
A frequent coding error is applying Replacement when the surgeon actually performed a Bypass, creating an alternate route around a blockage while leaving the diseased segment in place; Replacement requires that the original tissue segment be taken out, while Bypass does not. Coders also sometimes miss the distinction between Replacement and Supplement when a graft is used to reinforce rather than substitute for arterial tissue, and they should check the operative description for whether native tissue was removed before the graft was placed.
