Hypertrophy of bone, right femur

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

Apply this code when documentation explicitly states hypertrophy of the right femur. This typically occurs in conditions like Paget's disease, chronic osteomyelitis, or as a response to increased stress on the bone. Supporting documentation should include imaging reports (X-ray, CT, MRI) confirming bone overgrowth in the specified location.

• Ensure laterality is clearly documented (right vs. left femur).
• Investigate the underlying cause of the hypertrophy, as an additional code for the primary condition may be required.
• Differentiate from bone spurs (osteophytes) or exostoses, which have distinct ICD-10-CM codes.
