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
External Jugular Vein, Left
The left external jugular vein travels superficially over the sternocleidomastoid muscle, collecting blood from the scalp and superficial facial structures before draining into the subclavian vein. A segment is excised when it develops thrombophlebitis, frequently linked to prior venous access attempts, or when a localized varicosity or malformation along its length becomes symptomatic. Its superficial position relative to the deeper internal jugular vein and carotid sheath makes surgical access comparatively straightforward, generally requiring only a limited neck incision. The greater auricular nerve and other superficial cutaneous nerves crossing this region should be identified and preserved during dissection. Because this vein contributes secondarily to venous drainage of the head compared to the internal jugular system, removing a diseased segment typically has minimal effect on overall cerebral or facial venous outflow.
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.
Qualifier: Diagnostic
Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.
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.
