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
Tricuspid Valve
The tricuspid valve, the right-sided atrioventricular valve with three leaflets, is the valve most often affected by carcinoid syndrome, infective endocarditis related to intravenous drug use, and Ebstein's anomaly with its characteristic downward leaflet displacement. Excision of tricuspid tissue is typically performed to remove infected or destroyed leaflet segments in endocarditis, sometimes as a staged approach when the valve is excised without immediate replacement to clear infection before a later prosthetic implantation. Because the tricuspid valve tolerates a period of complete incompetence better than left-sided valves, isolated excision without simultaneous repair or replacement is a recognized, if temporary, surgical strategy in severe right-sided endocarditis. Documentation should indicate whether the excision was definitive or a staged step preceding delayed valve replacement.
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 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.
