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
Coronary Vein
The coronary veins, including the great, middle, and small cardiac veins that drain into the coronary sinus, run alongside the coronary arteries to return deoxygenated blood from the myocardium to the right atrium. Excision of a coronary vein is uncommon and is generally performed when a vein segment is diseased, aneurysmal, or must be removed to access an adjacent structure during another cardiac procedure, rather than as a standalone therapeutic goal. Because these veins have a thin, easily injured wall and lie in close proximity to the coronary arteries and epicardial surface, removing a segment requires careful dissection to avoid compromising arterial flow or precipitating bleeding. Operative notes should clearly distinguish excision, the cutting out of a vein segment, from ligation or division performed for other reasons during the same 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.
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 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.
