Operation Definition

Cutting out or off, without replacement, a portion of a body part

Procedure Overview

Excision procedures cut out a portion of a bursa or ligament without replacing it, leaving the remainder of the structure in place. This is done to remove diseased, damaged, or chronically inflamed tissue, such as a thickened bursa that has not responded to drainage or rest, or a partially torn ligament that needs debridement of frayed edges before repair.

A bursectomy, in which part of an inflamed bursa is removed, is a typical example, as is trimming away degenerated portions of a ligament during reconstructive surgery. Because only a portion of the structure is taken, the ligament or bursa continues to exist and function afterward, distinguishing this from a resection that removes the entire body part.

Excision is often performed as a standalone treatment for chronic bursitis or degenerative ligament disease, or as a preparatory step before repair or reconstruction.

Anatomy & Axis Detail

Elbow Bursa and Ligament, Right

On the right elbow, excision of bursal or ligamentous tissue most often involves the olecranon bursa, which overlies the tip of the elbow and is prone to chronic swelling from repetitive pressure, trauma, or infection that fails to resolve with drainage alone. When an olecranon bursa becomes persistently thickened, fibrotic, or recurrently infected, complete bursectomy is often chosen over simple drainage to prevent recurrence. Ligamentous excision at the elbow is less common but may be performed for a damaged or symptomatic portion of the collateral ligaments found unsalvageable during reconstructive surgery. Because the olecranon bursa lies just under thin skin with minimal soft tissue coverage, documentation should clarify the extent of tissue removed and confirm the procedure went beyond simple aspiration or incision and drainage.

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.

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 should confirm the note describes cutting out and removing a specific portion of tissue that is sent to pathology or discarded, as opposed to simply releasing or draining the structure. If the entire bursa or ligament is removed, the correct root operation is Resection rather than Excision, so the extent of removal documented by the surgeon is critical.

A frequent error is coding debridement performed as part of a repair as a separate Excision when it was an integral, inherent part of the definitive procedure and should not be coded separately. Biopsies of ligament or bursa tissue also fall under Excision and require attention to the diagnostic qualifier.

Commonly Confused With

ResectionExcision is most often confused with Resection, distinguished purely by whether all or only part of the ligament or bursa was removed.
ExtirpationIt is also distinguished from Extirpation, which removes abnormal solid material such as a calcified nodule or foreign body rather than a portion of the native structure itself.
