Maximum Medical Improvement in Texas Workers' Compensation Claims
Maximum medical improvement is the turning point of every Texas comp claim: the moment your temporary benefits end and your permanent impairment is measured. This section explains what MMI is, how it is decided, and what changes when you reach it.
The claim's turning point
Every Texas workers' comp claim with lost time eventually reaches the same milestone. Maximum medical improvement, called MMI, is the point at which your injury has recovered as much as it is reasonably going to. That can mean you healed completely. It can also mean your healing has leveled off and further material improvement is not expected, even though you are nowhere near the condition you were in before the injury.
What does MMI mean?
MMI stands for maximum medical improvement: the point where no further material recovery from your work injury can reasonably be anticipated. It is a medical judgment about your healing, certified by a doctor on form DWC069. It is not a statement that you are well, that you are pain-free, or that your medical care is over. When you see MMI on a letter such as PLN-03A or PLN-03B, the carrier is telling you a doctor has certified that point and your benefits are changing because of it.
There are three ways to reach MMI. A doctor can find you fully recovered. A doctor can find that your recovery has leveled off short of full health. Or the calendar can decide for you: after 104 weeks of temporary income benefits, roughly two years, the law deems you at MMI whether your body agrees or not. That third path, called statutory MMI, surprises more workers than any other rule in this section, and it has its own page: Statutory MMI: The 104-Week Clock on Temporary Benefits.
What changes at MMI
Two things happen at once. First, temporary income benefits (TIBs, the weekly checks that replace lost wages while you heal) end; they exist only for the healing period, and MMI is its legal endpoint. Second, a doctor evaluates whether the injury left you with permanent loss of function, expressed as an impairment rating. If the rating is above zero, impairment income benefits (IIBs, checks paid for the permanent damage itself) begin. Your checks change form at MMI; they do not automatically stop.
Your medical care does not end at MMI. Reasonable and necessary treatment for the compensable injury continues, in principle for life. Medical Treatment After Maximum Medical Improvement explains how that works in practice.
Can I be at MMI even if I'm still in pain?
Yes. MMI means your condition has stopped materially improving, not that it stopped hurting. Many workers are certified at MMI while still in daily pain, still on medication, and still under treatment. Pain that remains after MMI is addressed two ways: permanent loss of function is compensated through the impairment rating, and ongoing care for the injury remains covered after the rating is assigned.
If you believe the certification itself is wrong, that your condition was still genuinely improving when someone declared it finished, that is a dispute, and it has a deadline. Disputing a Maximum Medical Improvement Determination explains how to challenge an MMI finding, and the window for doing so is strict.

Attorney notes regarding MMI & impairment
MMI and impairment ratings are not just medical opinions sitting in your workers’ compensation file. They can affect when certain income benefits end, how much you are paid, and what benefits may be available later. Just as important, there may be a limited time to challenge them.
An MMI or impairment rating deserves a closer look when:
- You believe MMI was too early: Important treatment, surgery, or recovery may not have been fully considered.
- Part of your injury was left out: An impairment rating must be based on the compensable injury.
- The rating does not seem to match your condition: Permanent problems may not have been properly evaluated.
- Doctors disagree: A different medical opinion may provide grounds to challenge the certification.
- You are thinking about waiting: MMI and impairment disputes have deadlines. Waiting can turn a problem that could have been challenged into one that is much harder to fix.
At Abbott, Clay & Bedoy, we review MMI certifications, impairment ratings, medical records, and the conditions included in the compensable injury to identify problems and protect our clients’ rights.
Do not assume a rating is correct just because it came from a doctor. And do not assume you can challenge it whenever you are ready. We can review it and help determine whether action needs to be taken.
