CPT® Code 28193

The CPT® Code 28193 refers to the removal of a complicated foreign body from the foot. This procedure is necessary when the foreign body is located in deeper tissues, which may require extensive dissection for removal. Complicated foreign bodies can include those that have penetrated deeply, have been retained in the body causing infection, or are situated in areas that are difficult to access. The physician begins by inspecting the foot for any signs of a puncture site. If a puncture site is not visible, the foreign body may be located through palpation or by using radiographs that can be reported separately. The procedure involves making an incision in the foot and carefully dissecting the surrounding tissues while protecting vital structures such as ligaments, tendons, nerves, and blood vessels. Once the foreign body is located, it is removed, and the wound is treated by debriding any necrotic tissue and flushing it with normal saline to eliminate debris. Depending on the specifics of the injury, the wound may either be closed or left open to allow for drainage and healing by secondary intention.
