Serious injury care and records near St Marys
For a serious injury treated at Nepean Hospital in Kingswood, the admission records, imaging and any operation reports are often the core of the medical evidence. If scans, specialist reviews or surgery mean trips to Penrith, about 7 km away, keep a note of each trip and what it cost. Where you live needn't hold your claim back: advice and the claim check both work by phone and online, from home. Living in the Penrith City Council area doesn't change the rules on serious injuries: the threshold line and whole person impairment work the same way across NSW. What differs from person to person is the medical evidence.

Reading the threshold line
The scheme separates threshold injuries from more serious ones, and the difference shapes the whole claim. This is a general picture based on the scheme's definition. Your doctors describe the injury, the insurer decides where it falls, and that decision can be reviewed.
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

What 'serious' means in claim terms
Two measurements do most of the work when an injury is serious. One is the threshold line, which separates soft tissue and some psychological injuries from everything else. The other is whole person impairment, a percentage that describes lasting impairment. Between them, they affect how long statutory benefits can run and what a damages claim, if you have one, can include.

Long-term earning capacity
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.

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.
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 threshold rules and benefit periods depend on when your accident happened. Check which rules apply to your date before relying on any general statement.

Does a serious injury need a lawyer?
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
- Your injury may stop you returning to the work you did before
- An impairment assessment is coming up, or you disagree with one
- You have a fracture, a tear, nerve damage or a brain injury
- You have a psychological injury as well as a physical one
You may not need one
- You were mostly at fault, so no damages claim is open to you
- Your question is about treatment options, not compensation
- You want general scheme information that CTP Assist can give
With a serious injury, the right treating team matters for recovery and evidence alike. We can point you to doctors and allied health experienced with CTP, including GPs who complete the Certificate of Fitness.
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

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.

- How complete and current your medical records are

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.

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.

Building the evidence for a serious injury
Serious injury claims rest on medical evidence gathered over time: hospital records, imaging, operation reports, specialist opinions, and treating doctors' notes that track your progress. Your own records add the human detail. Start collecting early, keep everything in date order, and make sure each doctor knows about all your injuries, not just the one they're treating.
- Imaging reports, such as X-ray, CT or MRI, where done
- Operation and specialist reports
- Reports from a treating psychologist or psychiatrist, if any
- Any impairment assessment, and your response to it

Frequently asked questions
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.
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.
Not always. Whether scans are needed is a medical decision, and many injuries are diagnosed by examination. Where your doctor recommends imaging, it can show things an examination can't, such as a fracture, a tear or signs of nerve compression, and that can affect how the injury is classified. Keep copies of every imaging report, and don't arrange scans just for the claim.
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%.
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.
