Permanent disability is the part of a New Jersey workers' compensation case that measures what the injury took from you for good. After treatment ends, doctors evaluate the lasting loss of function, and the case resolves on a percentage: either of a specific body part listed in the statute, or of the body as a whole. That percentage converts to a number of weeks of benefits. If you can no longer work in any capacity, the claim is for permanent total disability instead.
What counts as permanent partial disability in New Jersey?
Not every injury that still aches qualifies. N.J.S.A. 34:15-36 requires a permanent impairment supported by demonstrable objective medical evidence that restricts the function of the body or one of its parts. The statute also asks whether the injury lessened your working ability to a material degree, and it excludes minor injuries, such as minor sprains and contusions, that don't produce a lasting restriction.
What this means in practice:
- Objective findings matter. Imaging, surgical findings, loss of range of motion, measurable weakness, and nerve testing carry weight. Pain alone, without findings, is harder to rate.
- Returning to work doesn't defeat the claim. The question is lost function, not lost wages.
- Everything should be on the table. Each injured body part, and conditions that followed from the injury, can be part of the rating if the medical evidence supports it.
How do disability percentages work?
The schedule in N.J.S.A. 34:15-12 assigns a number of weeks to specific body parts: fingers, hand, arm, toes, foot, leg, eye, hearing, and others. A rating of a percentage of the hand, for example, means that percentage of the weeks assigned to the hand.
Injuries that aren't on the schedule, such as the back, neck, and many internal or psychiatric conditions, are generally rated as a percentage of "partial total" disability, meaning the body as a whole.
Two features of the system often surprise people:
- The weekly rate rises in tiers. The weekly rate for permanent partial disability increases as the total number of weeks grows, so a higher percentage can be worth more than its size alone suggests.
- Prior disability can reduce an award. If you have a prior award or a measurable earlier disability in the same area, the carrier may be entitled to a credit for it.
How is permanency evaluated?
After you reach maximum medical improvement, usually two doctors examine you: one retained by your lawyer and one by the carrier. Each writes a report estimating your permanent disability, and the two numbers are often far apart. Neither is the answer.
The case then usually settles somewhere informed by both reports, your own description of how the injury affects your work and daily life, and the judge's view. If it doesn't settle, the judge hears the evidence and decides. Because permanency can't be measured until treatment is complete, settling too early, before the full picture is known, is a common mistake. Our step-by-step guide explains where this stage fits in the case.
What is permanent total disability?
Permanent total disability means you can't work in any capacity, not just your old job. Benefits are paid for 450 weeks and can continue after that if you remain unable to work.
These claims usually involve vocational as well as medical evidence. Where a pre-existing condition combines with the work injury to make a worker totally disabled, New Jersey's Second Injury Fund may pay part of the benefits. Social Security Disability and comp also interact through an offset, which needs attention in any total disability case. And when a work injury causes a death, dependents may be entitled to dependency benefits.
What is my case worth?
There is no formula a website can apply honestly, but these are the factors that drive a permanency award:
- The body part and its rating, scheduled or partial total.
- The percentage, and the tiered weekly rate it produces.
- Your average weekly wage, within the statewide limits.
- The medical findings, especially surgery and objective test results.
- How the injury affects your work and life, and how credibly that is presented.
- Prior disability credits, where they apply.
- Disputes over compensability, which can push a case toward a Section 20 settlement.
- Future medical needs, which affect whether keeping the case open matters.
If the carrier has stopped authorized treatment before you've recovered as far as you can, deal with that first; a rating taken too early undervalues the injury.
Talking to a lawyer about your situation
Permanency is where the size of a workers' comp case is decided, and it's the stage where having your own medical evaluation and someone to negotiate against the carrier's number makes the most difference. More about how the firm handles these cases is on the workers' compensation overview.

Frequently asked questions
Can I get a permanent disability award if I went back to my same job?
Yes. Permanent partial disability compensates a lasting loss of function, not lost wages. Many workers who return to their old jobs still have a measurable permanent impairment and receive an award for it.
What is the difference between a scheduled rating and partial total?
Body parts listed in the statute, such as a hand, arm, leg, or foot, are rated as a percentage of that part, which carries a fixed number of weeks. Injuries not on the schedule, such as the back or neck, are generally rated as a percentage of the body as a whole, called partial total.
Who decides my disability percentage?
In a settlement, the percentage is agreed between the parties and approved by the Judge of Compensation. If the case is tried, the judge decides after hearing your testimony and the evaluating doctors. The doctors' numbers inform the result, but they don't bind the judge.
Does a permanent total disability award last for life?
Benefits are paid for 450 weeks, and can continue after that if you remain unable to work. Continued payment depends on the facts, and offsets for other benefits may apply.
