What is maximum medical improvement (MMI)?
Maximum medical improvement, or MMI, is the point when an injury is not expected to heal or recover any further, even with more treatment. It does not mean you are fully healed. It means your condition has leveled off, so doctors and insurers can measure what is permanent and what future care you will need.

What does reaching MMI change? An example
Example: you injure your shoulder in a crash. After surgery and four months of therapy, your range of motion stops improving. Your doctor writes that you are at MMI, with some permanent loss of motion and a likely need for a steroid shot twice a year.
Now the claim can be valued with real numbers: past bills, the permanent limit on your shoulder, and the cost of those future shots. If you had settled at month two, before anyone knew the shoulder would not fully recover, you could have left the future care out of the number. The other driver’s insurer will ask you to sign a release promising no more claims for the accident, so missing costs usually cannot be added later.
Why does MMI matter to someone who was hurt?
It is often the right time to talk about settlement. Before MMI, nobody knows the full cost. After MMI, your doctor can say what is permanent. Many people wait for an MMI note before sending a demand, even though the deadline to sue keeps running in the meantime, so watch the statute of limitations.
In a work injury claim, MMI changes the checks you receive, as the next section shows.
How does MMI work in Texas workers’ compensation?
| Rule | What Texas says |
|---|---|
| Legal definition | The earliest date after which further material recovery or lasting improvement can no longer reasonably be anticipated, among other dates. |
| Temporary income benefits | Continue until the worker reaches MMI. |
| Statutory MMI | Reached at the end of 104 weeks of temporary income benefits. |
So in Texas, a worker can be at statutory MMI even if still improving, because the 104-week clock ran out. Other states set their own MMI rules for work injuries.
MMI vs. being fully recovered
Fully recovered means you are back to where you were before. MMI only means you have stopped getting better. You can be at MMI and still be in pain, still need care and still be unable to do your old job.
Questions
Who decides when I reach MMI?
Usually your treating doctor. In Texas work injury claims, disputes go through the state’s own exam process; see the IME entry.
Can MMI be wrong?
Yes, doctors can disagree. If your condition gets worse, tell your doctor and ask whether the MMI date should be reviewed.
Should I settle before MMI?
Settling early risks leaving out future care. Many people wait until their doctor can describe the long-term outlook.
