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
Pericardium
The pericardium is the fibrous and serous sac enveloping the heart, providing lubrication and a mechanical boundary that can become thickened, calcified, or adherent in constrictive pericarditis, or can develop cysts and tumors requiring removal. Excision of pericardial tissue involves cutting away a portion of this sac, commonly to obtain tissue for diagnosis in suspected malignancy or tuberculosis, or to remove a pericardial cyst, distinguishing it from the more extensive stripping performed in pericardiectomy for constrictive disease, which is typically coded as a Resection given the near-total removal involved. Because the pericardium lies adjacent to the phrenic nerves as they course toward the diaphragm, surgeons take care during excision to avoid nerve injury. Documentation should clarify the extent of tissue removed to differentiate a limited biopsy-type excision from a more complete pericardiectomy.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
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.
