What do the terms “MMI” and “permanent impairment rating” mean?
MMI and Permanent Impairment Rating sound as if they go hand in hand. However, they are two very different concepts. MMI means Maximum Medical Improvement. This is the point at which you have healed as much as you are likely to heal after an injury. Generally, this will be when the treating physician will discharge you from further treatment other than follow-up care. It is also the time when your treating physician determines your Permanent Impairment Rating. This is a rating following AMA (American Medical Association) guidelines to determine the extent to which the injury will affect your future quality of life. This in turn helps determine the appropriate compensation that you should receive.
