Myositis ossificans traumatica, unspecified hand

This code describes the formation of heterotopic bone within muscle tissue of an unspecified hand, occurring as a direct result of trauma. It represents a benign, non-neoplastic process where bone develops in soft tissues that do not normally ossify, specifically following an injury.

Apply this code when documentation indicates new bone formation within the muscle of the hand following a traumatic event, and the specific hand (left or right) is not specified. Supporting documentation should clearly link the ossification to a prior injury and confirm its location within the hand musculature.

• Ensure the documentation explicitly states "traumatic" to differentiate from progressive or non-traumatic forms of myositis ossificans.
• Avoid using this code if the laterality (left or right hand) is documented; instead, select the more specific code.
• Confirm the ossification is within muscle tissue, not a fracture callus or other bone anomaly.
