Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures in the upper veins involve cutting out a portion of a diseased or damaged vein without replacing it, most commonly to remove a segment affected by phlebitis, a varicosity, a tumor, or a section of vessel that has been injured. Because these are superficial or accessible veins in the arm, chest, or neck, excision is frequently done to relieve pain, improve appearance, or eliminate a source of clotting or infection rather than to restore blood flow, since the upper extremity has extensive collateral venous drainage.
A surgeon typically makes a small incision over the affected vein, isolates the segment, and removes it while leaving the surrounding tissue intact. Excised tissue may also be sent for biopsy when the reason for removal is to evaluate a suspicious growth or mass involving the vein wall.
Anatomy & Axis Detail
Basilic Vein, Left
The left basilic vein travels superficially along the ulnar aspect of the forearm and medial arm before joining the brachial veins to help form the axillary vein. Surgeons excise this vessel either to harvest a healthy segment for use as an autologous graft in bypass or fistula procedures, or to remove a portion damaged by recurrent thrombophlebitis, varicose dilation, or fibrosis from prior line placement. Its superficial location allows for a relatively direct surgical approach along the medial arm, though the medial antebrachial cutaneous nerve travels in close proximity and can be inadvertently injured if not identified. Because this vein is frequently relied upon for future vascular access, especially in patients with reduced kidney function, the decision to excise a segment is weighed against preserving remaining vein for later fistula creation. The excised tissue may be evaluated histologically if disease is suspected.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Coding & Documentation
Coders need documentation confirming that only a portion of the vein was removed, since removal of an entire named vein still falls under excision as long as it is not paired with a graft or synthetic replacement. The operative report should specify the exact vein segment taken and whether the tissue was sent to pathology, which supports the diagnostic qualifier when applicable.
A common mistake is defaulting to excision when the physician actually performed a resection that included reconstruction or bypass, which would instead be coded as a different root operation. Coders should also watch for procedures described as "stripping" a vein, which despite the informal terminology is typically coded to extraction rather than excision because force is used to pull the vessel out along its length.
