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

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.

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

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.

Commonly Confused With

SupplementSupplement is the closest and most frequently confused root operation, since both can involve grafting material into bone; the distinguishing factor is whether the material takes the place of a missing or resected bone segment (Replacement) or reinforces bone that is still structurally present (Supplement).
InsertionInsertion is distinct because it covers placing a device that doesn't physically substitute for bone tissue, such as a spacer.
RepositionReposition is unrelated in purpose, since it moves existing bone rather than replacing missing bone with new material.
