Major osseous defect, right humerus

This code signifies a significant loss of bone tissue in the right upper arm bone, the humerus. This defect is substantial enough to be considered "major," implying a significant structural compromise or void within the bone.

Apply this code when documentation explicitly states a "major osseous defect" of the right humerus, often following trauma, tumor resection, infection, or congenital anomaly. Supporting documentation typically includes imaging reports (X-ray, CT, MRI) detailing the size and location of the defect, and operative reports if surgical intervention occurred.

• Ensure the documentation specifies "major" to differentiate from minor or unspecified defects.
• Verify laterality (right humerus) is clearly documented; separate codes exist for the left and unspecified humerus.
• Consider sequencing this code after the underlying cause of the defect (e.g., fracture, osteomyelitis, neoplasm) if still active.
