MMI stands for “Maximum Medical Improvement.” Typically, your healthcare provider will issue a letter stating that you have reached MMI. Reaching MMI does not necessarily mean that you won’t have any more medical expenses – it just means that no significant improvement is expected. An MMI letter carries various legal consequences and is frequently an important factor in calculating the medical expenses component of your damages.
