US: Maximum Medical Improvement (MMI) is a treatment plateau in each person’s healing process. It can mean that the patient has fully recovered from the injury or that the patient’s medical condition has stabilized to the point that no major medical or emotional change can be expected in the injured workers’ condition. This occurs despite continuing medical treatment or rehabilitative programs the injured worker partakes in.
