By Michael Singh · 6 Min Read · In NSW, the first thing the CTP insurer does after receiving your claim is classify your injury as either minor or non-minor. This single classification controls how long you receive statutory benefits and whether you can ever pursue common law damages — including compensation for pain and suffering.
Why the classification matters so much
Under the Motor Accidents Injuries Act 2017 (MAIA):
- Minor injury — statutory benefits for up to 26 weeks from the accident date. No access to common law damages.
- Non-minor injury — statutory benefits may continue for longer while the claim resolves. Access to common law damages if you also meet the 10% Whole Person Impairment (WPI) threshold and can prove fault.
If your injury is classified minor when it should not be, you lose access to years of potential compensation. This classification is worth disputing if you believe it is wrong.
What is a minor injury?
MAIA defines a minor injury as a soft tissue injury or a minor psychological injury. A soft tissue injury is damage to muscles, tendons, or ligaments — sprains, strains, and whiplash-type injuries that do not involve structural damage to bones, joints, or nerves. A minor psychological injury is one that does not substantially impair the claimant's ability to carry out daily activities or participate in work.
What is NOT a minor injury
Under MAIA, the following are non-minor injuries regardless of how they present initially:
- Any fracture — including fractured ribs, stress fractures, and hairline fractures
- Structural damage to the spine — disc prolapse, disc bulge with nerve root compression, or disc herniation
- Nerve damage (radiculopathy, nerve root irritation)
- Burns or lacerations requiring surgical treatment
- Serious psychological injury — PTSD, major depressive disorder, or adjustment disorder that substantially impairs daily function
- Whiplash with a disc bulge confirmed on MRI
- Neck or back pain with nerve symptoms (pins and needles, weakness, radiating pain)
- PTSD following a serious collision
- Fractured ribs not apparent on initial X-ray
How the classification is made — and how to dispute it
The CTP insurer makes an initial classification based on your medical records. If they classify your injury as minor and you disagree, you can dispute the decision through SIRA's dispute resolution process. Insurers have a direct financial interest in classifying injuries as minor — do not accept an initial classification without getting legal advice if you have ongoing symptoms, neurological signs, or a confirmed structural injury on imaging.
The 10% WPI threshold for general damages
Even if your injury is classified non-minor, you still need to satisfy the 10% Whole Person Impairment (WPI) threshold before you can claim general damages (compensation for pain and suffering). This assessment is carried out by an independent medical examiner.
Importantly, there is no WPI threshold for economic loss claims. If your injury caused you to lose income due to the at-fault driver's negligence, you may be able to pursue that component without meeting the 10% threshold.
Frequently Asked Questions
What is the difference between a minor and non-minor injury under NSW CTP law?
Under the Motor Accidents Injuries Act 2017 (MAIA), injuries are classified as either minor or non-minor. A minor injury is a soft tissue injury or a minor psychological injury — sprains, strains, and psychological conditions expected to resolve within 26 weeks. A non-minor injury is any injury outside this definition — including fractures, dislocations, nerve damage, disc herniations confirmed by MRI, significant burns, and moderate or severe psychological injury. Minor injury claimants are limited to 26 weeks of statutory benefits, while non-minor injury claimants can access benefits for longer and may qualify for common law damages. The classification is one of the most consequential decisions in a NSW CTP claim.
Who decides whether my NSW car accident injury is minor or non-minor?
Initially, the CTP insurer makes the classification based on the medical reports you provide. If the insurer classifies your injury as minor and you disagree, you can dispute the classification through SIRA (the State Insurance Regulatory Authority). SIRA can appoint an independent medical assessor to make a binding determination. The classification can also change during your claim if new medical evidence is obtained — for example, if an MRI reveals disc herniations not visible on an initial X-ray. The insurer has a financial interest in a minor classification, so independent legal and medical advice before accepting any insurer decision is strongly recommended.
Can a psychological injury after a car accident be classified as non-minor in NSW?
Yes, but the threshold is higher than for physical injuries. A minor psychological injury is defined as an adjustment disorder or other transient condition. A non-minor psychological injury is a recognised psychiatric condition other than an adjustment disorder — including PTSD, major depressive disorder, and anxiety disorders meeting formal diagnostic criteria under DSM-5 or ICD-11. If you develop significant PTSD or depression following a road accident in NSW, your psychological injury may qualify as non-minor, entitling you to extended statutory benefits and potentially common law damages. The classification requires a formal assessment by a SIRA-accredited psychologist or psychiatrist, not simply a GP diagnosis.
