Myositis ossificans traumatica, right ankle and foot

This code signifies the presence of myositis ossificans, a condition characterized by the abnormal formation of bone within muscle tissue, specifically in the right ankle and foot. This particular diagnosis indicates that the ossification is a direct result of trauma to the affected area.

Apply this code when documentation clearly states a diagnosis of myositis ossificans in the right ankle or foot, and explicitly links its etiology to a traumatic event. Supporting documentation should include imaging reports (e.g., X-ray, CT scan) confirming heterotopic bone formation within the muscle, alongside a history of injury to the specified anatomical site.

• Ensure the documentation specifies "traumatica" to differentiate from other forms of myositis ossificans.
• Verify the laterality (right) and anatomical site (ankle and foot) are precisely documented.
• Do not confuse with calcification of soft tissue not specified as ossification, or with myositis without bone formation.
