Serious injuries usually mean long claims, with medical evidence gathered over months. It helps to understand the terms early: threshold injury, whole person impairment, non-economic loss. This page covers them in plain language for people in North Kellyville. It won't tell you what your claim is worth, because no honest page can. It will help you ask the right questions.

North Kellyville: hospitals, specialists and the medical record
If a serious injury was treated at Westmead Hospital, Hornsby Ku-ring-gai Hospital or elsewhere, the early scans and operation notes are key evidence of how bad it was. A serious injury can make every trip to Castle Hill 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. For people in The Hills Shire Council area, as anywhere in NSW, the test for a serious injury comes from the scheme's rules and your medical evidence, not from where you happen to live.

Serious injury: when legal advice helps
Serious injuries are where legal advice most often earns its place, because the stakes and the rules are both higher. Even so, not every serious injury claim needs a lawyer at every stage. Here is a general guide.
Often worth talking to a lawyer
- A pre-existing condition is being blamed for your symptoms
- You have a psychological injury as well as a physical one
- You have a fracture, a tear, nerve damage or a brain injury
- You're wondering whether your impairment could be more than 10%
You may not need one
- The insurer accepts the injury is more than threshold and benefits are flowing
- Your injury is healing as expected and should resolve fully
- The injury has settled with no lasting effect on your work or daily life
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?
- Hurt at work, or in a crash while you were working? That is usually a workers compensation claim first, which is a different scheme from CTP. Tell us what happened and we can point you to the right help. Free claim check

Reading the threshold line
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.
What 'serious' means in claim terms
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.

Who assesses impairment, and when
In a serious injury claim, impairment often comes into focus well after the crash, once treatment has run its course. The Personal Injury Commission handles medical assessment where the insurer and the injured person disagree. If you think an assessment is wrong, the steps to challenge it are set out separately, and the deadlines are short, so act promptly.
- Whether the injury has stabilised
- Whether every injured body part is included
- Scans or tests your doctors have ordered

The threshold line and what takes an injury past it
From 1 April 2023, the scheme uses the term threshold injury, which replaced the old term minor injury. A threshold injury is generally a soft tissue injury, a threshold psychological injury, or both. Soft tissue here means muscles, tendons, ligaments and similar tissue. Nerve damage is excluded, and so is a full or partial tear of a tendon, ligament, meniscus or cartilage.
Getting the classification right early helps. If you have symptoms that could point to nerve involvement or a tear, such as numbness, weakness, locking or a joint giving way, describe them to your doctor. Whether tests are needed is a medical decision. If a diagnosis changes, make sure the insurer has the new evidence, because the classification may need to change with it.
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.

What whole person impairment is
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.

Serious injury and your future earnings
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.

When the injury isn't only physical
Serious physical injuries often bring a psychological toll: sleeplessness, anxiety, depression or trauma symptoms. These can be part of your claim in their own right. Tell your doctor how you're coping, and ask about psychology if it would help. Whether a psychological injury is threshold or more is a medical and legal question, and the insurer's decision on it can be reviewed.

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
Each injury matters. Your claim should list every injury the crash caused, and your doctors should record all of them, not just the worst. The threshold limits generally apply where all your injuries are threshold injuries, so one injury that is more than threshold can change the whole claim. How several injuries are rated for impairment is technical, so get advice if it matters to you.
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.
Generally, yes, for the worsening the crash caused. A pre-existing condition, like arthritis or an old back injury, doesn't stop a claim, but the insurer may argue that some of your symptoms would have happened anyway. Clear evidence helps: records of how you were before the crash, and how you've been since. Tell your doctors about the earlier condition rather than leaving it out.
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.
Tell your doctor about the change, get it recorded, and make sure the insurer receives the new evidence. An earlier assessment may no longer reflect your condition, and in some circumstances the injury may be looked at again. Whether and how that happens depends on the stage of your claim and the rules for your situation, so this is a good point to get advice.
