Permanent Impairment Ratings and Settlements
At some point the medicine stops and the arithmetic starts. A physician assigns a percentage, a statute converts it into weeks, and the weeks become money — and then the insurer offers a lump sum to close everything, including the treatment that has not happened yet.
What this report covers
- Rating occurs only after maximum medical improvement is declared.
- Most states use a published impairment guide, and the edition in force affects the figure.
- Scheduled awards pay by body part regardless of actual wage loss; unscheduled awards turn on earning capacity.
- A disputed rating is answered with a second rating, not with an argument about fairness.
- Closing future medical benefits is usually irreversible and requires care where treatment will continue.
Every compensation claim eventually reaches the same intersection: a physician says the condition has stabilized, and the case turns from a medical matter into a valuation exercise conducted in percentages.
Maximum medical improvement
The declaration means the condition has plateaued and further material improvement is not expected. It does not mean recovery, and it does not necessarily end treatment — maintenance care frequently continues afterwards.
What it does is trigger the next phase: temporary wage benefits end, permanent impairment is assessed, and the claim moves toward resolution. Because of that, the timing is contested. Insurers have an interest in an early declaration; workers whose condition is still improving have an interest in delay, and an insurer-arranged examination is usually where an early declaration originates.
How a rating is produced
Most states adopt a published guide to the evaluation of permanent impairment, and the edition in force matters: successive editions changed methodology substantially, and the same injury can rate differently under different editions.
A rating combines objective measurement — range of motion, strength, imaging, nerve testing — with the guide's tables, producing a percentage of impairment of the affected part or of the whole person. Two elements produce most disputes:
- Measurement technique, which the guides specify precisely and which is frequently performed loosely.
- Apportionment, where the rater attributes part of the impairment to a pre-existing condition, reducing the compensable share.
Who may rate is a threshold question that is easily missed. A number of states restrict ratings to physicians who have completed training in the applicable guide or hold a designation from the state agency, with the consequence that a treating physician of long standing may not be a qualified rater and the figure they assign carries no weight. Asking whether the rater is certified, and under which edition, is a cheaper inquiry than a dispute later. The rating also comes with a clock: in several states a rating served on the parties becomes binding unless an objection is filed within a defined period, so a worker who intends to obtain a second opinion needs to say so before arranging it.
Impairment is an anatomical or functional loss. Disability is the effect on the ability to earn. A percentage measures the first, and only some benefit structures translate it into the second. A worker whose rating is modest but whose occupation is now impossible is in a very different position from one with the same rating in a desk job.
Scheduled and unscheduled awards
| Scheduled | Unscheduled | |
|---|---|---|
| Applies to | Listed body parts — limbs, digits, eyes, hearing | Back, neck, internal, systemic and psychological conditions |
| Measured by | Statutory weeks for the part, multiplied by the percentage | Loss of earning capacity or wage difference |
| Wage loss relevant | Generally not | Central |
| Predictability | High | Low |
| Evidence needed | The rating | Rating, vocational evidence, labor market data |
The unscheduled category is where the largest disputes occur, because the outcome depends on vocational evidence as much as medical evidence — which is why the labor market survey and the transferable skills analysis matter so much at this stage.
What a settlement actually closes
Two structures dominate, and the difference between them is the most important thing in the document:
- Indemnity-only settlement. Resolves the wage and impairment portion; medical benefits remain open for the accepted condition.
- Full and final settlement. Closes everything, including all future medical treatment for the injury, permanently.
Before agreeing to the second, three questions need answers: what treatment is likely over the next ten to twenty years, what it costs at today's prices, and what happens if the condition deteriorates. The treating physician can answer the first, and without it the figure is being accepted blind.
A further complication arises where the worker is or will become eligible for federal health coverage. Because that program's interests must be considered before its benefits pay for treatment related to a settled claim, settlements closing future medical frequently require a set-aside — a portion allocated to future injury-related treatment and administered separately. Ignoring it can jeopardize the federal coverage later.
What comes out before the worker is paid
The figure discussed across the table is rarely the figure that arrives. Several interests attach to a compensation recovery and are satisfied out of it, usually in an order the statute or the approving judge fixes.
| Claim on the money | How it is handled |
|---|---|
| Attorney fees | Percentage capped by statute and approved by the judge or board |
| Litigation costs | Records, rating evaluations, expert reports — itemized and approved |
| Unpaid medical bills and provider liens | Paid or negotiated before disbursement |
| Child support arrears | Withheld in most states, often after a registry search |
| Health plan or public benefit reimbursement | Asserted against treatment the plan paid for |
| Advances and overpayments | Credited against the settlement figure |
Child support is the deduction that most often produces an unpleasant surprise at signing. A number of states require the parties or the approving authority to check the support registry before a settlement is approved and to withhold any arrears from the proceeds, and the obligation is not waivable by agreement between the worker and the insurer. Where arrears exist, addressing them with the support agency in advance — including any modification available for a period of disability — is better than discovering the deduction after the amount has been budgeted.
The same applies to unpaid providers. Bills for treatment the insurer denied do not disappear on settlement; they are either resolved in the agreement, negotiated down before disbursement, or left with the worker.
Approval and finality
Most states require a compensation judge or board to approve a settlement, examining whether it is adequate and whether an unrepresented worker understands it. That review is real but limited: it is not a substitute for advice, and approval does not make a poor bargain a good one.
Reopening is narrow everywhere — typically limited to fraud, mutual mistake, or a change in condition within a defined period where the settlement did not close that right. A settlement that expressly closes future medical is generally the end.
Where a separate defendant contributed to the injury, the analysis changes again, because a third-party claim can recover damages the compensation system does not pay — and settling the compensation claim without addressing the insurer's reimbursement interest in that recovery creates problems that surface later.

Questions readers ask
What does maximum medical improvement mean?
That the condition has stabilized and further material improvement is not expected with treatment. It does not mean recovered or pain-free, and it does not necessarily mean treatment stops. It is the trigger that ends temporary wage benefits and begins the permanent impairment assessment, which is why insurers press for it and why its timing is frequently disputed.
Can I challenge a rating I think is too low?
Yes, and the effective route is another rating rather than an objection. Obtain an evaluation from a qualified rater applying the same guide, identify where the two diverge — measurement technique, the table applied, whether apportionment to a pre-existing condition was justified — and put the difference in front of whoever decides. Most states also provide a neutral or agreed rater to break the tie.
Should I take the lump sum?
It depends almost entirely on what it closes. A settlement that resolves the indemnity portion while leaving medical benefits open is a different proposition from one that closes everything permanently. Before agreeing, get the treating physician's view on what treatment is likely over the next decade and what it costs. Once medical benefits are closed, returning is generally impossible.
