Myositis ossificans traumatica, right forearm

This code signifies the presence of myositis ossificans, a condition characterized by heterotopic bone formation within muscle tissue, specifically in the right forearm. This particular subtype, "traumatica," indicates that the ossification is a sequela of a prior injury or trauma to the muscle.

This code is appropriate when documentation clearly states a diagnosis of myositis ossificans in the right forearm, and the etiology is attributed to trauma. Supporting documentation would include physician notes detailing the history of injury, physical examination findings, and imaging reports (e.g., X-ray, MRI) confirming the presence of heterotopic ossification in the specified anatomical location.

• Ensure the documentation explicitly states "traumatic" myositis ossificans to differentiate from other forms.
• Verify the laterality and anatomical site (right forearm) are clearly documented.
• Consider sequencing this code after any acute injury codes if the myositis ossificans is a direct complication of a recent trauma.
