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

Acetabulum, Left

The left acetabulum forms the socket of the hip joint and, like its counterpart on the right, is commonly replaced when arthritic wear, avascular necrosis, dysplasia, or fracture has destroyed the joint surface beyond what repair or reposition could correct. Acetabular replacement substitutes the native bony socket with a prosthetic cup, sometimes supplemented by screws or an augment when bone stock is deficient, and is typically performed alongside replacement of the femoral head as part of total hip arthroplasty. Revision surgery for a loosened or worn prior acetabular component is also coded here, since the native or previously implanted socket is again being substituted with a new device.

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.

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.
