Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Excision procedures cut out and remove a portion of a heart structure or great vessel without replacing it with anything else. Only part of the body part is taken, distinguishing it from more extensive removal of an entire structure. This might involve removing a segment of diseased tissue, a small mass, or an abnormal growth from within a heart chamber or vessel wall.
Surgeons perform these procedures for reasons ranging from removing a tumor such as a myxoma, to taking a tissue sample for biopsy, to trimming away scarred or damaged tissue that is affecting heart function. Because only a portion of the structure is removed, the underlying body part continues to exist afterward, just in an altered or reduced form.
Anatomy & Axis Detail
Pulmonary Trunk
The pulmonary trunk is the large vessel carrying deoxygenated blood from the right ventricle toward the branch pulmonary arteries, and it can be affected by post-stenotic dilation, aneurysm, or rare primary sarcomas that arise within its wall. Excision of pulmonary trunk tissue is performed to remove a segment affected by tumor or aneurysmal degeneration, or to resect tissue during repair of congenital anomalies such as truncus arteriosus where the trunk must be separated from associated structures. Because the pulmonary trunk sits in close proximity to the aortic root and the bifurcation into the branch pulmonary arteries, precise excision margins are important to preserve adequate vessel length for subsequent reconstruction or conduit placement. Operative documentation should specify whether the excised segment was proximal, near the pulmonary valve, or distal, near the bifurcation, since this affects the reconstructive approach taken afterward.
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 operative documentation confirming that only part of the body part was removed and that nothing was excised in its entirety, since removal of an entire body part changes the root operation to Resection. Biopsies are a frequent source of confusion: when a sample is taken purely for diagnostic purposes it is still coded as Excision, and the qualifier for diagnostic intent should be applied when documentation supports it. A common error is coding Excision when the surgeon actually removed the entire structure, such as an entire appendage or vessel segment between two anatomic landmarks, which instead requires Resection; another is missing that tissue removed as an inherent part of a more extensive procedure, like debris cleared during a bypass, is not separately coded.
