Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures on the upper arteries involve cutting out a portion of an artery in the chest, neck, shoulder, or arm without replacing the tissue removed. Surgeons perform this when a segment of vessel wall has been damaged by trauma, contains a diseased or aneurysmal section, or holds a tumor or growth that needs to be removed for diagnosis or treatment. Common targets include the subclavian, axillary, brachial, and carotid arteries, along with the thoracic aorta and its major branches supplying the upper body.
The removed tissue is often small relative to the vessel and does not always require reconstruction of the artery afterward, distinguishing it from more extensive resections. Patients undergo this procedure to address localized disease, obtain a biopsy sample, or clear away scarred or narrowed sections that are interfering with blood flow to the arms, neck, or brain.
Anatomy & Axis Detail
Radial Artery, Left
The left radial artery runs along the lateral forearm from the brachial bifurcation down to the wrist, providing the pulse most often felt at the wrist and serving as a frequent access point for catheter procedures, though it is used somewhat less often than the right for transradial cardiac catheterization. Excision of a segment is performed either to harvest the vessel as a bypass conduit or to remove a portion compromised by thrombosis, spasm-related injury, or a post-procedural complication from repeated access. Its superficial position and smaller caliber compared to the ulnar artery make it technically accessible but also more prone to vasospasm during dissection, so the operative record should note whether the harvested or excised segment was used for graft purposes.
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.
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 assign an Excision code when the operative note documents that only a portion of the artery wall or a discrete lesion was cut out, with no device left behind to replace the excised tissue. Supporting documentation should specify the exact artery involved down to the branch level available in the code tables, since upper artery anatomy is finely subdivided between innominate, subclavian, axillary, brachial, and their many named branches.
The most frequent assignment error is confusing Excision with Resection when an entire arterial segment or branch is removed rather than just a portion, or with Extirpation when the material taken out is a clot, foreign body, or other abnormal solid matter rather than vessel tissue itself. Coders also need to check whether the excision was performed as a biopsy, which changes the qualifier used, and whether an autograft was harvested from the artery for use elsewhere, which is coded separately from a diagnostic or therapeutic excision.
