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
Pelvic Bone, Right
The right pelvic bone, comprising the ilium, ischium, and pubis fused around the acetabulum, forms half of the bony pelvic ring and anchors the hip joint along with major muscle attachments for the trunk and thigh. Replacement of this body part occurs when extensive bone loss from tumor resection, severe comminuted fracture, or failed prior reconstruction requires substituting a structural or custom implant for the native pelvic bone, distinct from acetabular component replacement performed during routine hip arthroplasty. Given the pelvis's proximity to major vessels and the lumbosacral plexus, these reconstructions are typically extensive, and documentation should make clear whether the replaced segment is the pelvic bone itself rather than the acetabulum, which is coded separately.
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: 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.
