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 in the upper bones involve removing all or part of a bone in the skull, face, thorax, or upper limb and substituting it with a device or biological material that takes over its structural role. Cranioplasty with a synthetic plate after a skull defect, and prosthetic reconstruction of a portion of the humerus or clavicle following tumor removal, are typical examples.
These procedures are performed when a bone is too damaged, diseased, or absent to be repaired or repositioned, and the patient needs a physical substitute to maintain the shape of the skull or the mechanical function of a limb. The material can be a synthetic implant, such as titanium mesh or bone cement, or biological tissue, such as an allograft.
Anatomy & Axis Detail
Glenoid Cavity, Left
On the left, the glenoid cavity forms the socket component of the glenohumeral joint, and its relatively small, curved articular surface makes it vulnerable to progressive bone erosion in advanced arthritis or after loosening of a previous implant. Replacement of the glenoid bone itself, using structural graft or an augmented component, is undertaken to restore version and depth before any humeral-side reconstruction proceeds, since inadequate glenoid bone stock is a leading cause of arthroplasty failure. The procedure is distinct from simple resurfacing and is reserved for cases where native bone can no longer support a standard implant. Coders should verify from the operative report that the glenoid, not the scapular body or the joint surface generally, is the structure being replaced.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Nonautologous Tissue Substitute
Nonautologous Tissue Substitute refers to biologic material sourced from a donor or another species, such as an allograft or xenograft, used to replace a body part. It differs from Autologous Tissue Substitute by tissue origin outside the patient's own body, and from Synthetic Substitute by being biologic rather than manufactured material.
Coding & Documentation
Coding from this family requires documentation that a body part was actually taken out and something physically put in its place, not simply reinforced. The device value must match the material used - synthetic versus autologous versus nonautologous tissue - so operative notes describing the graft source matter for accurate code selection. A recurring error is coding replacement when the native bone was left in place and only augmented, which belongs under supplement instead. Coders should also confirm whether the replaced segment is a full bone or only a portion, since this affects the body part value chosen.
