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
Carpal Joint, Right
The right carpal joint refers to the articulations among the eight small carpal bones that form the intricate midcarpal and intercarpal linkages of the wrist. Excision at this level is generally performed to remove degenerated cartilage, a bone spur, or diseased synovial tissue causing pain or restricted motion, often in the setting of osteoarthritis, avascular necrosis of a carpal bone, or chronic ligamentous instability. Because several small joints exist between adjacent carpal bones, precise identification of which articulation was addressed is important for accurate documentation, distinguishing this from procedures on the radiocarpal joint itself. The tight packing of bones and interosseous ligaments in this region demands meticulous technique to preserve the surrounding structures while removing only the targeted portion of joint tissue, since excessive disruption can compromise carpal alignment and function.
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 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.
