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 describes procedures that remove a diseased or damaged segment of an upper-body vein - such as the subclavian, axillary, brachial, or innominate vein - and substitute it with a graft, whether that graft is a segment of the patient's own vein, donor tissue, or a synthetic conduit. It is performed when a portion of vein is too damaged, scarred, or obstructed to repair directly, commonly after trauma, following removal of a tumor invading the vessel wall, or as part of reconstructing venous drainage after prior surgery or radiation.
For patients, this means the surgeon is not just patching the vein but physically taking out a section and installing a replacement channel to keep blood flowing normally back toward the heart. It differs from arterial bypass grafting because it addresses the low-pressure venous system, and it is far less common than arterial replacement since veins have more collateral pathways and are often ligated rather than reconstructed.
Anatomy & Axis Detail
Axillary Vein, Right
The right axillary vein continues from the basilic vein at the lower border of the teres major and becomes the subclavian vein at the outer border of the first rib, running alongside the axillary artery within the neurovascular sheath of the axilla. Its central position makes it a target for aneurysmal degeneration, effort-related thrombosis, and iatrogenic injury during axillary lymph node dissection or shoulder surgery. Replacement becomes necessary when the segment is aneurysmal, thrombosed beyond recanalization, or resected with adjacent breast or soft tissue malignancy, and restoring the conduit protects both arm drainage and any downstream dialysis access built on more distal veins. Care in the axilla also requires attention to adjacent brachial plexus branches during graft placement.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
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
Replacement is coded when the operative note documents excision of a vein segment followed by insertion of graft material - autologous vein, cadaveric allograft, or synthetic material - to physically take over that vein's function. Look for language such as "interposition graft," "vein graft replacement," or "synthetic conduit reconstruction" tied to a specific named vein.
A frequent error is coding Replacement when the surgeon actually performed Supplement, laying graft material onto an intact vein rather than excising and substituting it; the distinction hinges on whether native tissue was removed. Coders should also confirm the graft material value is captured accurately, since autologous, nonautologous, and synthetic substitutes are each represented differently, and should avoid conflating a venous bypass graft (which creates a new route) with Replacement (which occupies the same anatomic position).
