Major osseous defect, unspecified shoulder region

This code signifies a significant loss of bone tissue in the shoulder region, where the specific location within the shoulder (e.g., humerus, scapula, clavicle) is not documented. This defect can result from trauma, infection, tumor resection, or congenital anomalies, leading to structural instability or functional impairment.

Use this code when documentation clearly indicates a "major osseous defect" of the shoulder but lacks specificity regarding the exact bone or part of the shoulder affected. This is appropriate when the physician's assessment confirms a substantial bone void without further anatomical detail.

• Avoid using this code if the specific bone (e.g., humerus, scapula) or even a more precise region (e.g., proximal humerus) is documented; instead, use a more specific code from the M89.7 category.
• Query the provider for greater specificity if possible, as a more precise anatomical site will lead to a more accurate code.
• This code should be sequenced as a primary diagnosis when the osseous defect is the primary reason for the encounter or treatment.
