Myositis ossificans traumatica, right hand

This code describes the development of heterotopic bone formation within muscle tissue of the right hand, specifically resulting from a traumatic injury. This condition is characterized by the abnormal growth of bone in soft tissues where bone does not normally exist, often following a contusion, fracture, or other trauma.

Use this code when documentation clearly indicates myositis ossificans in the right hand, with a direct causal link to a previous traumatic event. Supporting documentation should include a history of trauma to the right hand, imaging studies confirming heterotopic ossification, and a clinical diagnosis of myositis ossificans traumatica.

• Ensure the documentation specifies "traumatica" as the etiology; otherwise, consider other M61 subcategories.
• Verify the laterality is explicitly stated as "right hand" to avoid miscoding.
• Code any underlying or associated fracture or injury first, if still active, followed by this code.
