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

Lower Extremity Bursa and Ligament, Left

This value applies to bursae and ligaments of the left lower extremity that fall outside the specifically named hip, knee, ankle, and foot categories, such as structures along the thigh or lower leg. Excision removes a portion of such a bursa or ligament, commonly for a soft tissue mass, chronic bursal inflammation from repetitive trauma, or ligament tissue involved in a localized pathologic process. Because this is a catch-all location, coders and surgeons should first confirm that no more anatomically specific left lower extremity code applies before assigning this one. The procedure itself follows standard excision principles, removing the diseased portion while preserving surrounding musculoskeletal function, with documentation specifying the precise anatomic site within the extremity.

Approach: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

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.
