Hypertrophy of bone, left humerus

This code signifies an abnormal enlargement or overgrowth of bone tissue specifically affecting the left humerus. This hypertrophy can result from various underlying conditions, leading to increased bone density or size in this upper arm bone.

Apply this code when documentation clearly indicates an abnormal increase in the size or density of the left humerus. This is typically supported by imaging studies (X-rays, CT scans) and physician notes describing the bone hypertrophy.

• Ensure the laterality (left) and specific bone (humerus) are explicitly documented.
• Investigate and code any underlying cause of the bone hypertrophy if known and documented.
• Differentiate from bone spurs (osteophytes) or other bone overgrowths that may have more specific codes.
