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
Hand Vein, Left
The left hand's superficial venous network parallels the right, draining dorsally and palmarly into the cephalic and basilic veins at the wrist, and serves the same routine role as an access site for peripheral catheters and blood draws. Replacement of a hand vein on this side is similarly rare, arising mainly from reconstructive procedures after traumatic injury, frostbite, or tumor resection where a segment of superficial venous drainage must be restored, often using a microvascular vein graft. Left-hand involvement can carry particular functional weight for patients whose dominant hand is unaffected, and surgeons documenting the procedure should note the specific venous segment addressed given the variability of the hand's superficial venous pattern between individuals.
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: Nonautologous Tissue Substitute
Nonautologous Tissue Substitute refers to biologic material sourced from a donor or another species, such as an allograft or xenograft, used to replace a body part. It differs from Autologous Tissue Substitute by tissue origin outside the patient's own body, and from Synthetic Substitute by being biologic rather than 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).
