Hypertrophy of bone, right ankle and foot

This code signifies an abnormal increase in the size of bone tissue specifically located in the right ankle and/or foot. This enlargement is non-neoplastic and can result from various underlying processes, leading to potential pain, functional impairment, or cosmetic concerns.

Apply this code when documentation explicitly states hypertrophy of bone affecting the right ankle or foot. This diagnosis is typically supported by imaging studies (e.g., X-ray, MRI) demonstrating bone overgrowth, often in conjunction with clinical findings such as localized swelling or pain.

• Ensure the documentation specifies "hypertrophy" and not another bone condition like osteophyte formation or exostosis, which have different codes.
• Verify the laterality is explicitly documented as "right" for the ankle and/or foot.
• If the hypertrophy is secondary to another condition (e.g., osteoarthritis), sequence the underlying condition first, if applicable.
