After a car accident in NSW, some injuries are easy to see. Others, such as a mild brain injury, post-traumatic stress or depression, can be harder to recognise. If you are making an NSW CTP brain injury or psychological injury claim, knowing the rules early can make a real difference.
This guide explains how the Compulsory Third Party (CTP) Green Slip scheme works under the Motor Accident Injuries Act 2017, and where neuropsychological and psychological assessments fit.
Key points
- The NSW CTP scheme covers people injured in crashes on NSW roads on or after 1 December 2017, including drivers, passengers, riders, cyclists and pedestrians.
- Lodge your claim within 3 months of the crash, and within 28 days if you want lost earnings paid from the date of the crash.
- Adjustment disorder and acute stress disorder are threshold injuries. Other diagnosed conditions, such as PTSD and depression, are not.
- Damages for non-economic loss need permanent impairment greater than 10%, and psychological and physical impairment are not combined.
- People with a severe brain injury may be eligible for icare Lifetime Care, whoever was at fault.
How the NSW CTP scheme works
Every registered vehicle in NSW has a CTP Green Slip. The scheme is regulated by the State Insurance Regulatory Authority (SIRA). SIRA’s guide for people injured in a motor crash explains that anyone injured in a crash on a NSW road on or after 1 December 2017 can apply. That includes drivers, passengers, motorcycle riders, cyclists and pedestrians, and covers both physical and psychological injuries.
Time limits to know
- Report the crash to police within 28 days.
- Lodge your claim within 3 months of the crash.
- Lodge within 28 days if you want lost earnings paid from the date of the crash.
- Common law damages claims generally need to be made within 3 years of the crash.
Statutory benefits and threshold injuries
For the first 52 weeks, you can usually claim statutory benefits. These cover medical and treatment costs, part of your weekly earnings if you cannot work, and some care costs. People who were wholly or mostly at fault are generally limited to benefits for up to 52 weeks.
After 52 weeks, whether benefits continue depends partly on whether you have a “threshold injury”. SIRA’s threshold injury guide explains that there are two types:
- Soft tissue injuries, such as whiplash and muscle strains.
- Threshold psychological or psychiatric injuries. Of the recognised psychiatric illnesses, only adjustment disorder and acute stress disorder are threshold injuries.
Conditions such as post-traumatic stress disorder (PTSD) and depression are not threshold injuries. Fractures, nerve injuries and some ligament and tendon injuries are also outside the threshold category. The insurer decides whether an injury is a threshold injury. If you disagree, you can ask for an internal review, and after that the Personal Injury Commission can resolve the dispute.
Why accurate diagnosis matters
Because the threshold rules depend on diagnosis, a careful psychological assessment matters. For example, symptoms that look like a short-term stress reaction in the first weeks may later meet criteria for PTSD or a depressive disorder. A clinician who takes a full history and uses validated measures can describe what is happening and how it has changed over time.
Brain injury after a car accident
A traumatic brain injury (TBI) happens when a blow or sudden movement disrupts how the brain works. It ranges from mild (often called concussion) to severe.
Signs of a brain injury can include:
- memory gaps around the crash, or trouble learning new information
- poor concentration and slower thinking
- headaches, dizziness, and sensitivity to light or noise
- fatigue, irritability or changes in personality
- difficulty planning, organising or managing work
Many of these symptoms overlap with pain, poor sleep, anxiety and depression, which are also common after a crash. That overlap is one reason a neuropsychological assessment can help. It can separate out the likely causes of thinking problems, which then guides the right treatment. For example, poor sleep and pain may respond to different help than a memory problem caused by the injury itself.
Severe brain injury and Lifetime Care
People with a severe injury may be eligible for icare’s Lifetime Care and Support Scheme. It is a no-fault scheme, so support does not depend on who caused the crash. For brain injury, the criteria include evidence such as post-traumatic amnesia (a period of confusion and memory loss after the injury) lasting longer than one week, or other evidence of a severe injury, along with measured functional impairment.
Damages claims and permanent impairment
SIRA’s page on applying for common law damages explains that you may be able to claim damages if someone else was at fault and your injuries are more than threshold injuries. Damages can include past and future loss of earnings.
Damages for non-economic loss (pain and suffering) need a permanent impairment of greater than 10%. Under Part 6 of the Motor Accident Guidelines, physical and psychological impairment must be assessed separately, and the two ratings cannot be combined to reach the 10% threshold. After a crash, a person may have both a brain injury and a psychological injury, so clear evidence about which problems come from which injury is important.
Where assessments fit
Treating assessments
A treating psychologist or neuropsychologist assesses you to plan recovery. A neuropsychological assessment measures memory, attention, processing speed, language and problem-solving, and considers how pain, mood and sleep are affecting results. The report can guide rehabilitation, return to work or study, and support at home. It also describes your strengths, which helps when planning what you can safely do now. A repeat assessment later can show whether things are improving, which is useful for both recovery planning and your claim. If you want the insurer to pay, check what approval it needs before booking.
Insurer and medico-legal assessments
The insurer may arrange an independent assessment, and your lawyer may ask for an independent neuropsychological or psychological report. Permanent impairment disputes can be referred to medical assessors at the Personal Injury Commission. Our guide on independent medical examinations explains what to expect.
Practical steps after a crash
- See a doctor soon after the crash, even if you feel fine. Some brain injury symptoms appear or become clearer over the following days.
- Tell your doctor about any memory gaps, confusion or loss of consciousness at the scene.
- Keep a simple diary of symptoms, such as headaches, fatigue, forgetfulness and mood changes, and how they affect work and home life.
- Ask a family member or friend to note changes they see in you. Others often notice changes before we do.
- Keep copies of hospital discharge papers, scans, receipts and letters from the insurer.
- Get legal advice early if you think you may have a damages claim, because time limits apply.
How Invictus Health can help
We have assessment clinics in NSW and several other states. Our neuropsychologists provide neuropsychological assessments after brain injury, and we prepare independent medico-legal assessments for lawyers and insurers. Neuropsychology reports are reviewed by Dr Judy Tang OAM.
You can self-refer for most assessments. If you want your CTP insurer to pay, ask them about approval first. Our fees page has more information. Our psychologists also provide counselling in person in Preston or by telehealth.

Frequently asked questions
Is concussion a threshold injury under NSW CTP?
The two threshold categories are soft tissue injuries and threshold psychological injuries, meaning adjustment disorder and acute stress disorder. Concussion is a brain injury, but how any injury is classified is decided by the insurer based on the medical evidence. If you disagree with the decision, you can ask for an internal review and then go to the Personal Injury Commission.
Is PTSD a threshold injury in NSW?
No. SIRA says only adjustment disorder and acute stress disorder are threshold psychological injuries. Recognised psychiatric illnesses such as PTSD and depression are not threshold injuries. This can affect whether benefits continue after 52 weeks, so an accurate diagnosis from a qualified clinician matters.
Can I claim CTP if the accident was my fault?
Yes. People who were at fault can still claim statutory benefits, but benefits are generally limited to 52 weeks for people who were wholly or mostly at fault. Common law damages are only available if someone else was at fault. People with a severe injury may be eligible for Lifetime Care whoever was at fault.
How long do I have to make a CTP claim in NSW?
SIRA says you should lodge your claim within 3 months of the crash, and within 28 days if you want lost earnings paid from the date of the crash. The crash should be reported to police within 28 days. Common law damages claims generally need to be made within 3 years. A lawyer can advise on exceptions.
Why do psychological and physical injuries get assessed separately?
The Motor Accident Guidelines require physical and psychological impairment to be rated separately. When deciding whether impairment is greater than 10% for non-economic loss, the two ratings cannot be added together. Each injury must reach the threshold on its own, which is why clear, separate evidence for each matters.
