Maximum medical improvement (MMI) is the point at which the condition of an injured person is stabilized. No further recovery or improvement is expected even with additional medical intervention. Basically, a condition is at maximum medical improvement if it is not believed that the condition will change or progress. This term is most often used in the context of a worker’s compensation claim. An inquired employee usually receives temporary benefits until reaching maximum medical improvement
The following is an example of a state statute (Ohio) on maximum medical improvement.
Maximum medical improvement is a treatment plateau at which no fundamental, functional or physiological change can be expected within reasonable medical probability in spite of continuing medical or rehabilitative procedures.[OAC Ann. 4121-3-32]
