A fracture, nerve damage, a brain injury or pain that won't settle can change the course of a claim. For people in North Rocks, this page explains how the NSW scheme draws the line between threshold and more serious injuries, and what whole person impairment measures. It is general information. Your own doctors' findings, and the insurer's decisions about them, are what count.

North Rocks: hospitals, specialists and the medical record
Sydney Metro North West and the T-way buses link the Hills with specialist care. For a serious injury, keep a running list of who you've seen and what each of them found. If you were admitted to Westmead Hospital after the crash, the admission notes, scans and specialist letters made there are often the first evidence of how serious the injury is. Ask for copies, or ask your GP to obtain them. A serious injury can make every trip to Parramatta a major effort. Claim help can stay at home, where the check is done by phone and online and documents can generally be signed without travelling.
If a serious injury means you need changes at home, or help getting around the City of Parramatta area, write down what you need and why. Treatment and care needs are part of what the insurer considers under the scheme.

Is your injury serious enough to get advice?
The more serious and lasting the injury, the more likely the claim will involve impairment assessments, damages and long timeframes. Those are the areas where a lawyer tends to help. These lists are a rough guide.
Often worth talking to a lawyer
- You're wondering whether your impairment could be more than 10%
- You have a fracture, a tear, nerve damage or a brain injury
- A pre-existing condition is being blamed for your symptoms
- The insurer has classed your injury as threshold and your doctors disagree
You may not need one
- The injury has settled with no lasting effect on your work or daily life
- Your question is about treatment options, not compensation
- The insurer accepts the injury is more than threshold and benefits are flowing

Threshold injury, or something more serious?
Where an injury falls against the threshold line affects how long statutory benefits can last and whether damages are possible. The comparison below is general. Symptoms alone don't decide it; the medical diagnosis does.
Usually treated as a threshold injury
- Sprains and strains of muscles, tendons or ligaments
- Whiplash-type neck pain with no nerve findings
- Bruising and soft tissue swelling
- A psychological injury the scheme classes as threshold
- Statutory benefits generally up to 52 weeks, for accidents from 1 April 2023
May be more than a threshold injury
- Nerve damage confirmed by a doctor
- A full or partial tear of a tendon, ligament, meniscus or cartilage
- A fracture, which is generally not a soft tissue injury
- A brain injury, or a diagnosed psychological condition beyond the threshold category
- Damages may be possible if another driver was at fault and you weren't mostly at fault
General information, not legal advice, and not medical advice either. The insurer decides on the medical evidence, its decision can be reviewed, and time limits apply.
Serious injury, in the scheme's language
In everyday speech, a serious injury is one that hurts a lot or takes a long time to heal. The CTP scheme uses narrower tests. The first is whether the injury is more than a threshold injury. The second, for some kinds of compensation, is how much permanent impairment it leaves, measured as whole person impairment. Pain matters to you, but the scheme looks at diagnosis and lasting effect.

The threshold line and what takes an injury past it
The threshold line is a medical line drawn by legal rules. Your doctor diagnoses the injury; the scheme's definition decides which side it falls on. Sprains, strains and whiplash without nerve findings usually sit on the threshold side. Confirmed nerve damage, a tear, a fracture or a brain injury generally takes an injury beyond it. The insurer makes the call, and you can challenge it.
The line also decides whether common law damages are open. With only a threshold injury, they generally aren't. With a more serious injury, you may be able to claim damages if another driver was at fault and you weren't mostly at fault. That is why a threshold decision is often the most important decision the insurer makes about a serious injury.
Check the date of your accident
The threshold rules and benefit periods depend on when your accident happened. Check which rules apply to your date before relying on any general statement.

WPI: the percentage behind serious injury claims
Whole person impairment, or WPI, is a percentage that describes how much a lasting injury affects the body as a whole. It isn't a measure of pain, and it isn't a measure of what you've lost. It's a medical assessment made under set guidelines once an injury has stabilised. In a CTP claim, WPI matters mainly for damages: non-economic loss is only available where WPI is more than 10%.
Because so much can turn on a few percentage points, WPI assessments are often contested. Your treating doctors, the insurer's chosen doctor and, if there's a dispute, a medical assessor through the Personal Injury Commission may reach different figures. Keep every report, and get advice before accepting an assessment you think is wrong.

Long-term earning capacity
Earning capacity compares what you could have earned without the injury with what you can realistically earn now. For a tradesperson with a damaged shoulder, or an office worker with a brain injury, that gap can be large and long-lasting. Record every change to your working life: hours, duties, roles you can no longer do. Those facts sit alongside the medical evidence.

The timing of an impairment assessment
Impairment is generally assessed once an injury has stabilised, meaning it's unlikely to change much with further treatment. Assessing too early can understate a serious injury. The insurer may arrange an assessment, your own doctors may give opinions, and if the insurer and you disagree about the degree of impairment, the Personal Injury Commission can carry out a medical assessment.
- Whether the injury has stabilised
- Whether every injured body part is included
- Whether you disagree with the result, and the deadline to say so

Mental health after a serious crash
A crash can cause psychological injury as well as physical injury, and sometimes instead of it. Some psychological injuries are classed as threshold injuries; others are not, depending on the diagnosis. Anxiety, low mood, flashbacks or fear of driving are worth raising with your GP early, both for your own sake and so the injury is recorded and properly diagnosed.

Building the evidence for a serious injury
The most persuasive serious injury claims usually have consistent evidence: the same injuries described the same way, from the hospital to the GP to specialists, with no unexplained gaps in treatment. That consistency comes from telling each doctor the full story and following treatment plans. If a report leaves something out, ask the doctor about it rather than letting it pass.
- Hospital admission and discharge records
- Imaging reports, such as X-ray, CT or MRI, where done
- Reports from a treating psychologist or psychiatrist, if any
- Any impairment assessment, and your response to it

Frequently asked questions
Generally, no. A threshold injury is generally a soft tissue injury, and a broken bone isn't soft tissue. So a fracture caused by the crash will usually take the injury beyond the threshold, although the insurer still decides on the medical evidence. If you have a fracture along with soft tissue injuries, make sure the fracture is clearly recorded on every certificate and report.
More than one person may. Your treating doctors can give opinions, the insurer may send you to a doctor it chooses, and where you and the insurer disagree about the degree of impairment, a medical assessor at the Personal Injury Commission can decide it. Timing matters as much as who: an assessment made before the injury has settled can understate it. To challenge an assessment, see the CTP claim denied page, and act quickly because the deadlines are short.
Tell every doctor about it, even if it seemed mild at first. A brain injury isn't a soft tissue injury, so a diagnosed brain injury is generally more than threshold. Symptoms such as headaches, memory problems, fatigue or changes in mood can take time to show and are easy to put down to stress. Record them, and ask your GP whether further review is needed.
Possibly. A soft tissue injury with nerve damage, or with a full or partial tear of a tendon, ligament, meniscus or cartilage, is generally not a threshold injury. If yours is more than threshold, another driver was at fault and you weren't mostly at fault, you may be able to claim damages, including loss of earnings. Pain and suffering needs WPI of more than 10%.
Yes. Psychological injuries caused by the crash can be claimed along with physical injuries. Some are classed as threshold injuries and others are not, depending on the diagnosis. Tell your GP how you're coping, including sleep, mood and any fear of travelling, so it's recorded. If you're referred to a psychologist or psychiatrist, their reports become part of the evidence.
It can. The insurer's decision is based on the evidence it has at the time. If a new diagnosis comes to light, such as nerve damage or a tear, the insurer can be asked to look at the classification again. If you disagree with a decision, there's a formal process to challenge it, starting with an internal review, and the CTP claim denied page explains those steps and their deadlines.
