When You Reach Maximum Medical Improvement
Updated January 24, 2026
The point in recovery when a worker's condition has stabilized and further medical treatment is unlikely to result in significant improvement.
Understanding Maximum Medical Improvement (MMI)
MMI is determined by the treating physician and marks a transition from temporary to permanent disability benefits. At MMI, a permanent impairment rating is assigned based on the remaining limitations. This doesn't mean the worker is fully healed, just that they've reached maximum recovery.
Examples
- 1Back injury patient reaching MMI after 18 months
- 2Doctor assigning 15% permanent impairment at MMI
- 3Transition from TTD to permanent disability benefits
