For people in Constitution Hill, 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.

Serious injury care and records near Constitution Hill
A serious injury often needs follow-up with several specialists. From Parramatta, the Western Line and light rail help; keep every report together, in date order, including those from Westmead Hospital or Auburn Hospital. Scans and surgery may mean travel, but claim help doesn't have to. Constitution Hill is about 23 km from the Sydney CBD, and the claim check runs by phone and online. Many lawyers work with seriously injured people the same way. Whether you live in the City of Parramatta area or elsewhere, the scheme measures a serious injury the same way. The local part is your treating team, and the record they keep of your injury over time.

Is your injury serious enough to get advice?
If your injury is more than threshold, it's worth at least one conversation with someone who knows the scheme. Whether you need more than that depends on your situation. Use these lists as a starting point.
Often worth talking to a lawyer
- A pre-existing condition is being blamed for your symptoms
- You're wondering whether your impairment could be more than 10%
- You have a psychological injury as well as a physical one
- You have a fracture, a tear, nerve damage or a brain injury
You may not need one
- You were mostly at fault, so no damages claim is open to you
- The injury has settled with no lasting effect on your work or daily life
- You want general scheme information that CTP Assist can give
If you're not sure your injury has been fully investigated, a doctor experienced with CTP can help. We can suggest doctors and allied health familiar with the Certificate of Fitness and serious injury care.
Not quite your situation?
- If the injury happened at work, including on the road for work, workers compensation is usually the scheme that applies first, not CTP. After a crash, a CTP damages claim may still be possible. We can point you to the right help. Free claim check

Which side of the threshold line your injury may fall
Think of this as a map, not a verdict. It shows the kinds of injury usually treated as threshold, and the findings that may take an injury beyond it. Only the medical evidence in your own claim can place you.
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.
When an injury counts as serious
An injury can be serious in human terms and still sit on the threshold side of the line, and the reverse can happen too. That can feel unfair. It helps to know the scheme's tests are about the type of injury and its lasting effects, not how much you've suffered. Knowing which test applies lets you and your doctors focus on the evidence that matters.

The timing of an impairment assessment
There's usually no single moment when WPI is measured. Opinions may come from treating doctors, from doctors the insurer arranges, and, where the two sides disagree, from a medical assessment through the Personal Injury Commission. Timing matters, because injuries can improve or worsen for months. A lawyer can advise whether an assessment is premature before you rely on it.
- How complete and current your medical records are
- Changes in your condition since the last report
- Whether you disagree with the result, and the deadline to say so

Threshold injuries and beyond
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.
Which side you're on matters. For accidents from 1 April 2023, statutory benefits for a threshold injury generally last up to 52 weeks. For accidents between 1 December 2017 and 31 March 2023, the limit was 26 weeks. If your injury is more than threshold and you weren't mostly at fault, benefits can generally continue for longer, and a damages claim may be possible.
Check the date of your accident
The scheme has been amended over time, most recently for accidents from 1 April 2023. Rules change, so check the current rules for your accident date.

Psychological injury and the threshold
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.

When an injury limits your work for years
A serious injury can change more than the next few months of work. It can limit the kind of work you can do for years, or permanently. In a damages claim, that is called loss of future earning capacity, and it can be a significant part of a serious injury claim. It generally needs evidence from your doctors, your work history and sometimes vocational experts.

Whole person impairment, explained
WPI turns a lasting injury into a percentage. A doctor examines you and rates the impairment under the assessment guidelines that apply to motor accident claims. The number doesn't reflect how hard your life has become; it reflects measurable impairment. Even so, it can decide important questions, especially whether damages for pain and suffering are possible.
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.

What shows an injury is serious
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
- Operation and specialist reports

Frequently asked questions
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's a percentage, often shortened to WPI, that a doctor gives to the lasting impairment an injury leaves. It's usually assessed once the injury has stabilised, and it measures impairment, not pain or lost income. The figure to know is 10%. Above it, damages for pain and suffering become possible and some timing rules for a damages claim change. At 10% or less, lost earnings can still be claimed if the other conditions for damages are met.
It could. Tingling, numbness or weakness can sometimes point to nerve involvement, and confirmed nerve damage takes an injury outside the threshold definition. These symptoms can also have other causes, so it's a question for your doctor, who can decide whether tests are needed. Describe the symptoms precisely, note when they started, and make sure any diagnosis reaches the insurer.
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%.
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.
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.
