What is Maximum Medical Improvement (MMI)?

MMI is when an injured person’s condition stabilizes, and no further improvement or recovery is expected, even with additional care and treatment. In simpler terms, it means the injury has recovered as much as possible. This term is commonly used in workers’ compensation cases, where temporary benefits are provided until the patient reaches MMI. At this point, the patient is assessed for permanent disability and any further benefits. Insurance companies typically stop paying for treatments if a doctor believes the condition cannot improve.
