Operation Definition

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

Procedure Overview

Excision in the upper joints refers to cutting away a portion of joint tissue, such as diseased synovium, a bone spur at the joint margin, torn cartilage, or a segment of the joint capsule, without replacing what was removed. Surgeons excise tissue from the shoulder, elbow, wrist, or finger joints to relieve pain, restore range of motion, or send a tissue sample for diagnosis when imaging alone cannot explain a patient's symptoms.

Common reasons for this type of procedure include synovectomy for rheumatoid or inflammatory arthritis, debridement of a labral or cartilage tear, or removal of an osteophyte that is blocking joint movement. Because only a portion of the structure is taken and the joint itself is not replaced or reconstructed, patients typically recover function through physical therapy rather than needing an implant or prosthesis afterward.

Anatomy & Axis Detail

Carpometacarpal Joint, Right

The right carpometacarpal joints connect the distal carpal row to the bases of the metacarpal bones, with the thumb's carpometacarpal joint being a particularly mobile saddle-shaped articulation prone to degenerative change. Excision here most commonly targets osteoarthritic cartilage or osteophytes at the thumb base, a frequent site of painful arthritis in the hand, or diseased synovium and capsule at one of the other carpometacarpal joints affecting grip strength. Because the thumb carpometacarpal joint bears disproportionate mechanical stress during pinch and grasp activities, excisional procedures there are especially common and often considered alongside other reconstructive options. Documentation should specify which carpometacarpal articulation was involved, since the thumb joint's biomechanics and surgical approach differ meaningfully from the more constrained joints at the bases of the index through little finger metacarpals.

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 must confirm the operative note describes removal of only part of the joint structure, and identify whether the intent was diagnostic (a biopsy sent to pathology) or therapeutic. The approach, open versus percutaneous endoscopic, must be pulled from the documentation since it changes the code entirely, and arthroscopic synovectomies are extremely common and easy to miss if the note simply says "arthroscopy" without detailing what was excised. A frequent mistake is defaulting to Excision when the surgeon actually removed an entire structure, such as a whole bursa or the full synovial lining, which would instead be Resection; the distinction hinges on whether any portion of that anatomic structure remains.

Commonly Confused With

ResectionResection is the closest relative and is used instead of Excision whenever the entire body part, not just a portion, is taken out.
ExtirpationDebridement of loose or infected material is frequently Extirpation rather than Excision when the substance removed is not organized tissue attached to the joint but rather free debris or foreign matter.
FusionFusion procedures may also involve excising cartilage from joint surfaces as a preparatory step, but when the intent and result is joining the bones together, the case is coded as Fusion, not Excision, even though excision occurs along the way.
