Threshold Injury or Not? What the Classification Means for Your CTP Claim
In a NSW motor accident claim, one word on an insurer’s letter can quietly shape everything that follows. That word is whether your injury is classified as a threshold injury. It sounds like a piece of bureaucratic labelling, but it is one of the most consequential decisions in the whole scheme, because it determines how long your benefits last and whether you can ever claim a lump sum for what the accident has cost you.
Understanding the difference between a threshold injury and an injury that is more than a threshold injury, and what each means for your entitlements, is essential to knowing where your claim stands. It is not about how the injury happened or how much pain you are in day to day. It is a specific legal classification with very specific consequences.
This guide explains what a threshold injury is, which injuries fall on each side of the line, and what the classification means for your benefits and your right to damages. Please treat it as general information rather than advice about your own claim, and you should seek legal advice about your particular situation before making decisions about it.
What is a threshold injury under the NSW CTP scheme?
The term comes from the Motor Accident Injuries Act 2017 (NSW), the scheme regulated by the State Insurance Regulatory Authority, known as SIRA. A threshold injury, which the scheme originally called a minor injury, is defined as either a soft tissue injury or a psychological or psychiatric injury that is not a recognised psychiatric illness.
Everything turns on that definition, because the scheme treats threshold injuries very differently from injuries that go beyond it. The label is not a comment on how serious your injury feels or how much it has disrupted your life. It is a technical classification, and an injury that is genuinely painful and disabling in everyday terms can still fall within the threshold definition.
The classification matters because the scheme is designed to provide broad early support to almost everyone injured on the road, while reserving longer term benefits and lump sum damages for those whose injuries are more than threshold injuries.
Which injuries fall on each side of the line
On the physical side, a soft tissue injury is an injury to the tissue that connects, supports or surrounds other structures in the body, such as muscles, tendons and ligaments. Whiplash, sprains and strains are the classic examples, and they are threshold injuries. What lifts an injury above the threshold is significant. Fractures, injuries to the nerves, radiculopathy, and a complete or partial rupture of a tendon, ligament, meniscus or cartilage are all more than threshold injuries.
On the psychological side, a general emotional reaction to an accident that does not amount to a recognised illness is treated as a threshold injury, and so, unusually, are adjustment disorder and acute stress disorder, which the scheme specifically classes as threshold injuries. A diagnosed psychiatric illness such as post traumatic stress disorder or major depression, however, is more than a threshold injury.
The table below shows the practical difference the classification makes.
| Threshold injury | More than a threshold injury | |
|---|---|---|
| Examples | Soft tissue injuries such as whiplash, sprains and strains, and minor psychological reactions | Fractures, nerve injuries, radiculopathy and ruptures, and recognised psychiatric illnesses such as post traumatic stress disorder |
| Weekly payments and treatment | Generally limited to the first 52 weeks | Can continue beyond 52 weeks if you were not wholly or mostly at fault |
| Common law damages | Not available | Available where another party was at fault |
| Pain and suffering damages | Not available | Available where impairment is greater than 10 per cent |
What the classification means for your benefits
For the first 52 weeks after the accident, statutory benefits, meaning your weekly income support and your treatment and care, are generally available regardless of how your injury is classified and regardless of fault. In that first year, a threshold injury and a more serious injury are largely treated the same way.
The difference appears after 52 weeks. If your injuries are threshold injuries, your statutory benefits generally stop at that point. If your injuries are more than threshold injuries, and you were not wholly or mostly at fault, your income support and treatment can continue beyond the first year, and in the case of treatment and care, potentially for much longer.
So the classification does not usually affect your early support, but it decides whether that support continues once the initial period ends. For someone whose recovery takes longer than a year, that is a significant difference.
What the classification means for your right to damages
This is where the classification carries its greatest weight. A common law damages claim, the lump sum that compensates the longer term cost of a serious injury, is simply not available for a threshold injury. The Act is explicit that no damages are payable for threshold injuries.
If your injuries are more than threshold injuries, and another party was at fault, the door to damages opens. You may be able to claim for your past and future loss of earnings, and, if your permanent impairment is greater than 10 per cent, for pain and suffering as well. None of that is available to someone whose injuries remain within the threshold definition.
In other words, the threshold classification is the first gateway to the entire damages side of the scheme. Clear it, and further questions about fault and impairment come into play. Fail to clear it, and the damages claim does not get off the ground, no matter how much the injury has affected your life.
Why one injury beyond the threshold changes everything
There is a crucial point of relief in all of this, and it is one many injured people do not realise. You do not need every injury to be more than a threshold injury. If even one of your injuries falls outside the threshold definition, your claim as a whole is treated as being more than a threshold injury claim.
That single fact often decides a claim. Someone with several soft tissue injuries plus one fracture, or plus a diagnosed psychiatric illness, is not confined to the threshold rules, because that one non threshold injury lifts the whole claim. It is why the careful identification and documentation of every injury, including psychological conditions and injuries that only become apparent later, matters so much.
How and when the classification is decided
The insurer makes the threshold injury decision, based on the medical evidence, usually within around nine months of your claim. It is required to give you its decision, and the reasons for it, in writing.
Two things are worth understanding about this. First, the classification is largely a diagnosis based question, decided relatively early, and it is separate from the later assessment of your whole person impairment as a percentage, which is used for the damages thresholds. They are different questions at different stages, and it is easy to confuse them. Second, because the decision is made on the medical evidence in front of the insurer, it is only as good as that evidence, which is why these classifications are so often contested and, on review, changed.
If you disagree with the classification
Because the threshold classification controls so much, it is worth challenging when it is wrong. A threshold injury decision is a medical dispute, which means it can be reviewed by the insurer and then referred to an independent medical assessor at the Personal Injury Commission, whose determination on the question is binding. Many of these decisions are overturned once stronger and more focused medical evidence is provided. We explain how to do that in our dedicated guide on what to do when the insurer says your injury is a threshold injury.
How Stephen Young Lawyers can help
The threshold classification is deceptively important. It looks like a technical label, but it sits at the foundation of your entitlements, deciding both whether your benefits continue past the first year and whether you can pursue a damages claim at all. Getting it right, and challenging it when it is wrong, can be the difference between a modest and a substantial outcome.
An experienced personal injury lawyer makes sure every injury is properly identified and documented, that your evidence addresses the actual definition rather than just naming your diagnosis, and that an incorrect classification is challenged through the Personal Injury Commission. Because this decision affects everything downstream, it is one of the most valuable points in a claim to get advice on.
