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
Knee Bursa and Ligament, Left
This body part covers the bursae and ligaments of the left knee, including the prepatellar and pes anserine bursae and the peripheral ligamentous structures that stabilize the joint outside the cruciate and meniscal anatomy coded elsewhere. Excision removes part of one of these structures, typically for a persistently swollen or thickened bursa unresponsive to conservative care, a bursal cyst, or a degenerated ligament segment identified during arthroscopy. Since the knee bears significant mechanical load, surgeons take care to preserve joint stability while excising only the diseased portion, and the approach may be open or arthroscopic depending on depth and location. Accurate coding depends on the operative note clearly identifying the left knee and the specific bursa or ligament excised rather than the joint capsule or cartilage.
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 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.
