If you’ve heard your doctor or adjuster say “MMI,” pay attention — it’s one of the most important moments in your entire claim, and it’s frequently misunderstood.
MMI is not “you’re better”
Maximum Medical Improvement means your condition has plateaued — further treatment isn’t expected to meaningfully improve it. You can reach MMI and still be in pain, still have restrictions, still be unable to do your old job. MMI is a medical milestone about recovery curve, not about whether you’re whole.
Why MMI changes everything
At MMI, the claim pivots from “treat the injury” to “account for what’s permanent”:
- Benefit category shifts. Temporary benefits may end or convert to a different type.
- An impairment rating is assigned. A doctor assigns a percentage that quantifies your permanent impairment.
- In Florida, MMI is a classic point where the carrier stops checks — sometimes prematurely or based on the carrier-friendly doctor’s opinion.
- Settlement value crystallizes. The rating and your wage drive what the claim is worth.
The impairment rating fight
That percentage isn’t objective truth — it depends on which doctor, which edition of the guides, and how thoroughly your limitations were documented. A rating that’s a few points low can cost thousands. This is one of the quietest places claims get shortchanged.
What to do at MMI
- Don’t assume the rating is correct — you may be entitled to a second opinion or an IME.
- Don’t accept a settlement number generated off a low rating.
- Understand what future medical you’ll need before closing anything out.

Quick answers
What does maximum medical improvement (MMI) mean? +
MMI is the point where your doctor decides your condition has stabilized and isn't expected to improve much further with treatment. It doesn't mean you're healed — it means you're as recovered as you're likely to get. At MMI, the focus shifts from treatment to your permanent impairment rating.
What happens to my checks when I reach MMI? +
MMI often changes your benefit category. Temporary disability benefits may end or convert, and a permanent impairment rating is assigned that drives permanent benefits or settlement value. In Florida especially, reaching MMI is a common point where checks stop — which is why the rating matters enormously.
