CPT® Code 20520

The procedure described by CPT® Code 20520 involves the removal of a foreign body that has become lodged within a muscle or tendon sheath. This is classified as a simple removal, indicating that the procedure does not involve extensive dissection or complications. The physician typically performs this procedure when a patient presents with a foreign object that may cause pain, inflammation, or other complications if left untreated. The process begins with the physician making an incision above the area where the foreign body is located. Through this incision, the cutaneous tissue is carefully dissected to access the foreign body. Once the foreign object is located, it is removed from the muscle or tendon sheath. After the removal, the site is assessed for infection; if no infection is present, the incision site is closed. However, if there is evidence of infection, the site may be left open and packed with gauze to promote healing and prevent further complications. It is important to note that if radiologic imaging is required to locate the foreign body, this service should be reported separately. For cases where the removal is more complex or involves deeper structures, CPT® Code 20525 should be used instead of 20520.
