Hypertrophy of bone, right humerus

This code describes an abnormal increase in the size of the bone tissue in the right humerus. This hypertrophy can result from various underlying conditions, leading to thickening and increased density of the bone.

Use this code when documentation explicitly states hypertrophy of the right humerus. This typically occurs in conditions such as Paget's disease, chronic osteomyelitis, or as a reactive process to stress or trauma. Imaging reports (X-ray, CT, MRI) confirming bone hypertrophy in the specified location are essential for accurate coding.

• Ensure the documentation specifies "hypertrophy" and not other bone abnormalities like osteosclerosis or exostosis, which have different codes.
• Verify the laterality (right) and the specific bone (humerus) are clearly documented.
• Code any underlying or associated conditions causing the hypertrophy, such as Paget's disease, as a primary diagnosis if applicable, with this code as a secondary diagnosis.
