What Is Maximum Medical Improvement (MMI) in NC Workers’ Comp?

Your doctor says you have reached maximum medical improvement, but your shoulder still aches and you are not sure what happens next. In North Carolina workers’ comp, maximum medical improvement (MMI) is the point where your treating doctor believes your condition has leveled off.

It does not mean you are healed, and it does not mean your benefits are over. It is the moment your impairment rating gets assigned, your permanent restrictions get set, and the insurance company starts thinking about how to close your file.

At Lewis & Keller Injury Lawyers, we hear from injured workers in Greensboro and Winston-Salem at exactly this stage, and the decisions made here shape the rest of the claim.

Key Takeaways for Maximum Medical Improvement in NC Workers’ Comp

• Maximum medical improvement means your condition has stabilized, not that you have healed or that your benefits are over.
• Reaching MMI does not by itself stop your weekly checks; an insurer generally needs Industrial Commission approval of a Form 24 unless you have returned to work.
• Your permanent impairment rating is converted into weeks of benefits using the schedule in N.C.G.S. 97-31, such as 300 weeks for the back and 240 weeks for an arm.
• If you disagree with your rating, N.C.G.S. 97-27(b) entitles you to a second rating exam by a qualified physician you choose, paid for by the employer.
• Your right to medical compensation generally ends two years after the last payment unless you file a Form 18M or the Commission orders more care before then.

What Does Maximum Medical Improvement Mean in a Workers’ Comp Claim?

Maximum medical improvement means your condition has stabilized, not that you have recovered. Your doctor expects no further significant improvement from treatment, even if you still have pain, weakness, or limited motion.

The North Carolina Workers’ Compensation Act does not define MMI. The North Carolina Court of Appeals has described MMI as the marker for when the “healing period” ends and the payment period for a permanent injury begins under the schedule in N.C.G.S. 97-31. In plain terms, MMI is the line between getting better and living with what is left.

Who Decides You Have Reached MMI?

Your authorized treating physician, the doctor the insurer approved to direct your care, usually makes the call. The Industrial Commission’s medical status questionnaire asks that doctor whether you have reached MMI and, if so, what permanent impairment each injured body part has.

That opinion carries weight, but it is not the final word. An early MMI date moves a claim toward closure faster, so it deserves scrutiny. If you are still in active treatment, waiting on a referral, or getting worse, the finding may be premature.

What Changes When You Reach MMI

Several things tend to happen close together once a doctor places you at MMI:

• Your doctor assigns a permanent partial disability rating, a percentage of lost use for each injured body part.
• You receive permanent work restrictions, or a release to return to work without restrictions.
• Settlement talks often begin, because the medical picture is finally clear enough to put a number on the claim.

One thing that does not automatically happen: your weekly checks do not stop just because you reached MMI. Under N.C.G.S. 97-18.1, an insurer that wants to terminate or suspend temporary total disability payments generally needs Commission approval of a Form 24 application, unless you have returned to work.

North Carolina courts have held that MMI alone does not end your right to wage-loss benefits if your injury still keeps you from earning your old wages.

How Your Impairment Rating Becomes Scheduled Compensation

North Carolina does not use AMA “whole person” ratings. Doctors here follow the Industrial Commission Rating Guide, which was written by North Carolina physicians for use with the state’s statute. The guide itself says a rating is appropriate at the end of the healing period and that the final rating should be the examining doctor’s independent opinion.

The rating then plugs into the schedule in North Carolina’s permanent partial disability statute. Each body part is assigned a number of weeks for total loss of use. A few examples from the schedule:

Body part	Weeks for total loss of use	Weeks for a 10% rating
Back	300	30
Arm	240	24
Hand or leg	200	20
Foot	144	14.4
Thumb	75	7.5

The statute pays partial loss of use in proportion to total loss. A 10 percent rating to the arm equals 24 weeks of benefits, and a 5 percent rating to the back equals 15 weeks.

Each week is paid at your compensation rate, which is two-thirds of your average weekly wage, up to the state maximum. These payments are owed based on the permanent injury itself, whether or not you have gone back to work.

A few percentage points can mean weeks of benefits, so the rating deserves a careful look rather than a quick signature.

Choosing Between Wage-Loss Benefits and Your Rating

North Carolina law does not let you collect weekly disability benefits and scheduled rating benefits for the same period. Instead, N.C.G.S. 97-29 says you are entitled to select the statutory compensation that provides the more favorable remedy.

The choice matters most when you cannot go back to your old job. If restrictions keep you out of work or push you into lower-paying work, ongoing benefits under 97-29 or 97-30 may be worth far more than a rating paid over a few dozen weeks.

Time limits shape the choice. Temporary total disability is generally capped at 500 weeks from the date of first disability.

Partial disability benefits are also capped at 500 weeks, and weeks already paid as total disability count against that limit. Extended compensation beyond 500 weeks is available only in narrow cases, where the worker proves a total loss of wage-earning capacity.

When to take the rating, if at all, depends on your restrictions, your job prospects, and how many weeks you have already been paid.

How to Challenge a Premature MMI Finding or a Low Rating

You do not have to accept an MMI date or rating you believe is wrong.

A second opinion on your rating. Under N.C.G.S. 97-27(b), if you are dissatisfied with the percentage of permanent disability your authorized provider assigns, you are entitled to another examination on that percentage by a qualified physician you choose.

The employer pays that doctor, and you cover your own travel. The exam is limited to the rating, so the Commission must disregard or give less weight to that doctor’s opinions on other issues.

A change of treating physician. If you believe you need more treatment before anyone rates you, N.C.G.S. 97-25(c) allows you to ask the Commission to approve a different provider. You have to show the change is reasonably necessary to effect a cure, provide relief, or lessen the period of disability.

A hearing. When doctors disagree, or the insurer will not budge, either side can file a Form 33 asking the Commission to set the claim for hearing. The Commission then decides the percentage of disability. Form 33 and related claim forms are posted on the North Carolina Industrial Commission forms page.

Can You Still Get Medical Treatment After MMI?

Yes, but there is a deadline, and it catches many people off guard. Under N.C.G.S. 97-25.1, your right to medical compensation ends two years after the employer’s last payment of medical or indemnity compensation.

It continues only if, before that period runs out, you file an application for additional medical compensation that the Commission approves, or the Commission orders more care on its own.

That application is Form 18M. When the insurer finishes paying, it files a Form 28B reporting its final payments, and that form carries a notice about this two-year rule.

If you will need prescriptions, injections, or a later surgery, the two-year clock is one of the most important dates in your claim. The Commission can also order future medical care when there is a substantial risk you will need it.

A Costly Mistake to Avoid at MMI

A costly, avoidable mistake at this stage is signing off on a rating without anyone reviewing it. After MMI, an insurer may send a Form 26A, the Employer’s Admission of Employee’s Right to Permanent Partial Disability. It lists your rating and the weeks the insurer plans to pay, and it can look like routine paperwork.

Before you sign, ask two questions: does the rating match your real limitations, and is taking it better than continuing wage-loss benefits? Settlement deserves the same care.

The Commission must approve a settlement as fair and just under N.C.G.S. 97-17, but once approved, it is very hard to undo. Results depend on the specific facts of your case.

Frequently Asked Questions

How long after MMI do you get a settlement in North Carolina?

There is no set timeline for a workers’ comp settlement after MMI in North Carolina. Settlement is voluntary. Some claims settle soon after MMI, others take much longer, and some never settle. Any settlement agreement must be approved by the North Carolina Industrial Commission before it becomes final.

What is an anticipated MMI date in workers’ comp?

An anticipated MMI date is a treating doctor’s estimate of when your condition will stop improving. It is a prediction, not a ruling, and in a North Carolina workers’ comp claim the doctor can move the date if your recovery is slower than expected or if new treatment is needed.

Is reaching MMI the same as being released to full duty?

No. Reaching MMI in a North Carolina workers’ comp claim means your condition has plateaued, and many workers reach MMI with permanent restrictions. A full duty release means the doctor sets no work limits.

What does a 0 percent impairment rating mean in NC workers’ comp?

A 0 percent rating means the treating doctor found no permanent loss of use, so no scheduled benefits are owed under N.C.G.S. 97-31 based on that rating. It does not by itself end medical care or wage-loss benefits that are otherwise owed, and you can request a second rating examination under N.C.G.S. 97-27(b) if you disagree.

What if my injury gets worse after reaching MMI in North Carolina?

If your work injury worsens after MMI, you may be able to ask the North Carolina Industrial Commission to review your award for a change in condition under N.C.G.S. 97-47.

That request generally must be made within two years of the last payment of compensation under an award, or within 12 months of the award when only medical bills were paid. Separate deadlines apply to future medical care.
