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
Innominate Artery
The innominate artery, also known as the brachiocephalic trunk, is the first and largest branch off the aortic arch, dividing into the right common carotid and right subclavian arteries and therefore supplying blood to both the right arm and the brain. Excision of a segment is a high-stakes undertaking, usually performed for an aneurysm, dissection, or occlusive plaque, since this short vessel lies deep in the superior mediastinum near the trachea and great veins. Because it feeds both cerebral and upper limb circulation, any resection typically requires temporary shunting or bypass to maintain perfusion during the procedure, and precise documentation of the extent of vessel removed helps distinguish a limited excision from a more extensive replacement or bypass operation.
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.
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.
