Operation Definition
Taking or cutting out solid matter from a body part
Procedure Overview
Extirpation procedures take or cut out solid matter that does not belong in a bursa or ligament, such as calcified deposits, loose bodies, blood clots, or foreign material. Unlike excision, the material removed is abnormal rather than being a piece of the ligament or bursa itself. A common scenario is removal of calcific deposits from a chronically inflamed bursa, sometimes called calcific bursitis, or clearing a hematoma that has formed within a ligament sheath after injury.
These procedures are often performed when conservative treatment or drainage alone has failed to resolve symptoms caused by the trapped material. The approach may be open, arthroscopic, or through a small percutaneous access depending on the size and location of the deposit.
By removing the obstructing or irritating material, extirpation aims to relieve pain and restore normal movement without removing any of the surrounding healthy ligament or bursa tissue.
Anatomy & Axis Detail
Knee Bursa and Ligament, Right
The right knee bursa and ligament group includes major stabilizers such as the collateral and cruciate-adjacent ligamentous tissue along with prominent bursae like the prepatellar, infrapatellar, and pes anserine bursae that are frequently affected by friction and repetitive kneeling. Extirpation targets solid abnormal material, such as a calcified loose body lodged in a bursal sac, an organized hematoma, or gouty deposits within the ligament, removing it without excising the ligament or bursa. Because the knee is a high-use weight-bearing joint with superficial and deep bursae in close proximity to the joint capsule, arthroscopic or open approaches are chosen based on how deep the material lies, and clear identification of the specific bursa or ligament is important given how many discrete structures the knee contains.
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
The documentation should identify the removed material as abnormal solid matter, such as calcium deposits, debris, or a clot, rather than native tissue. Coders should look for terms like removal, debris clearance, or evacuation of calcification rather than excision or resection language.
A common mistake is defaulting to Excision whenever tissue is cut, without checking whether what was actually removed was foreign or abnormal material versus a piece of the ligament or bursa itself. When both native tissue and abnormal material are removed in the same operative episode, coders must determine whether one procedure was incidental to the other or whether both should be captured.
