Operation Definition
Taking out or off a device from a body part
Procedure Overview
Removal procedures take out a device that was previously placed in or on a lower bone - hardware such as plates, screws, rods, pins, external fixator components, or spacers used in the pelvis, femur, tibia, fibula, patella, or foot bones. These devices are typically inserted to stabilize a fracture, hold a bone graft, or support a joint during healing, and removal happens once that purpose has been served or if the device is causing a problem.
Reasons for removal vary widely. Hardware may simply be scheduled for extraction after a fracture has healed, especially in children whose growing bones can be irritated by permanent implants. In other cases the device is removed because it has become infected, has loosened, is causing pain from irritating overlying soft tissue, or is interfering with a later procedure such as a joint replacement.
Anatomy & Axis Detail
Patella, Left
The left patella is the sesamoid bone anterior to the knee, embedded in the quadriceps tendon, and Removal here refers to taking out a previously placed device rather than excising bone or tissue. Patellar fractures and tracking disorders are frequently stabilized with tension-band wires, cannulated screws, or Kirschner wires, and these implants are removed once healing is confirmed or if they cause anterior knee pain, hardware prominence under the thin overlying skin, or irritation during kneeling. Because the patella sits directly beneath the skin with minimal soft-tissue coverage, hardware migration or symptomatic prominence is common, making elective removal a frequent outpatient procedure. Documentation should specify the type of device extracted and confirm no residual bone fragment or foreign material remains within the joint space.
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.
Device: Synthetic Substitute
Synthetic Substitute designates a device made from manufactured, non-biologic material, such as mesh or prosthetic components, used to replace or augment a body part. It is distinguished from the two tissue substitute categories by its artificial composition, which carries different considerations for integration and long-term durability than biologic grafts.
Coding & Documentation
Coders assign Removal when documentation confirms a device is being taken out and not replaced with another device during the same operative episode - if a new device goes in at the same site, the procedure is Change or a combination of Removal and another root operation such as Insertion, not Removal alone. The device type and the specific bone it was removed from both need to be identifiable from the operative note. A common error is coding Removal for hardware that is only being adjusted or repositioned rather than fully extracted, or overlooking that the removal of a device is bundled into a broader procedure when substantial additional work, like bone repair, is performed at the same site.
