Myositis ossificans progressiva, right foot

This code signifies the presence of myositis ossificans progressiva, a rare genetic disorder characterized by progressive heterotopic ossification of soft tissues, specifically affecting the right foot. This condition leads to the formation of bone in muscles, tendons, and ligaments, causing pain, stiffness, and restricted movement.

Apply this code when documentation confirms a diagnosis of myositis ossificans progressiva with specific involvement of the right foot. This diagnosis is typically made based on clinical presentation, imaging studies (e.g., X-rays, CT scans), and genetic testing.

• Ensure documentation clearly specifies "progressiva" to differentiate from localized myositis ossificans.
• Verify laterality (right foot) is explicitly stated in the medical record.
• Consider co-reporting with codes for associated symptoms or complications, such as pain or functional impairment, if documented.
