Operation Definition
Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part
Procedure Overview
Replacement procedures put in biological or synthetic material that physically takes over the role of all or part of a lower bone. This includes structural bone grafts, cadaver bone allografts, and synthetic bone substitutes used to rebuild a portion of the pelvis, femur, tibia, fibula, or foot bones after tumor resection, severe trauma, or bone loss from infection.
These procedures are performed when a segment of bone is missing or so damaged that it can no longer support the body's structure or function on its own, and simply repairing or repositioning the remaining bone isn't enough. A patient who has had a tumor removed from the femoral shaft, for example, may need the resulting gap filled with a structural allograft to restore the bone's load-bearing capacity.
Anatomy & Axis Detail
Upper Femur, Left
The upper femur, comprising the head, neck, and greater and lesser trochanters, forms the ball of the hip joint and anchors the abductor and short rotator muscles. Replacement of this segment typically corresponds to hip arthroplasty, where the native head and neck are resected and a metal or ceramic femoral component with a modular head is implanted, most often for displaced femoral neck fracture, advanced osteoarthritis, avascular necrosis, or a failed prior fixation device. Restoring proper offset, version, and leg length is essential here because this region transmits the body's weight into the femoral shaft. When an acetabular cup is also placed, that portion is captured separately, so documentation should reflect whether the procedure is a hemiarthroplasty or a total hip replacement.
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: Autologous Tissue Substitute
Autologous Tissue Substitute identifies a device value where material harvested from the patient's own body, such as an autograft, is used to replace or reconstruct a body part. Its defining feature is tissue origin from the patient, setting it apart from Nonautologous Tissue Substitute, sourced from a donor or animal, and Synthetic Substitute, made of manufactured material.
Coding & Documentation
Documentation must describe material being put in that takes over the physical role of the bone segment - not material that merely reinforces existing bone, which would be Supplement instead. The type of graft or substitute material and the specific bone segment addressed both need to be clear in the operative note. A frequent error is coding Replacement when bone graft is used to fill a defect but the native bone structure is still largely intact and functional, which points toward Supplement rather than Replacement; another is confusing joint replacement procedures, which are coded to the Lower Joints body system, with bone-segment replacement coded here.
