What happened: A NSW review panel nearly doubled a PTSD impairment rating after a rear-end crash, pushing the assessment over the 10% threshold that unlocks non-economic loss damages.
Who's involved: NRMA (CTP insurer) and a claimant assessed under the NSW motor accident scheme.
What's at stake: The difference between 8% and 14% whole person impairment - and with it, the claimant's eligibility for non-economic loss damages.
Why it matters: Category-level rating disputes in impairment assessments can flip threshold outcomes and transform an insurer's liability exposure overnight.
Where it stands: Decided - the review panel revoked the original certificate and substituted 14% WPI.
She heard a loud bang and thought it was an explosion. It took a moment to realise she had been rear-ended near the M4 exit at Parramatta.
Four years later, that July 2022 crash has produced a ruling that CTP claims professionals will want to read closely. A NSW Personal Injury Commission review panel has revoked an original PTSD assessment of 8% whole person impairment and substituted 14% - nearly doubling the rating and pushing it well past the 10% threshold that unlocks non-economic loss damages under the Motor Accident Injuries Act 2017.
The insurer on the file is NRMA.
The original medical assessor examined the claimant in June 2025 and certified 8% WPI for post-traumatic stress disorder. He rated her as mildly impaired across most functional categories - self-care, travel, social functioning, concentration, and adaptation - with moderate impairment only in social and recreational activities. His aggregate score came to 13, producing a median class of 2, a base rating of 7%, and a final figure of 8% after adding 1% for treatment effect.
The claimant challenged the assessment. Her submissions argued the original assessor had placed her in the wrong class for three categories: self-care and personal hygiene, social functioning, and concentration.
On self-care, for instance, the original assessor acknowledged that the claimant's daughter ordered and delivered her food, helped with cleaning, and handled online shopping - and that the claimant showered only once every two to three days. He rated her Class 2 (mild) because she still lived alone, which he took as evidence she could live independently. The claimant's argument was straightforward: living alone while relying on regular support from a family member is not the same thing as living independently.
NRMA pushed back. The insurer argued the original assessor had provided adequate reasons, exercised proper clinical judgment, and correctly separated the effects of physical pain from psychological impairment. There was no basis for referral to a review panel, the insurer submitted.
The matter was referred anyway.
Two panel psychiatrists re-examined the claimant by video in July 2026. Their assessment painted a fuller picture. The claimant, now 66, had migrated to Australia in 2002, later earned qualifications through Sydney University, and had worked as an English teacher at TAFE since 2016. She continued to work 17.5 hours a week - 10 hours of face-to-face teaching, seven and a half hours of preparation - but reported she was not performing as well as she would like.
The panel noted a pre-existing history of recurrent depression dating from approximately 2003, with treatment including medication and psychological counselling. There was no evidence of PTSD before the accident.
Where the panel diverged from the original assessor was in how it scored two of the six functional categories. It upgraded both social functioning and adaptation from Class 2 (mild) to Class 3 (moderate). On social functioning, the panel found it clinically significant that the claimant had not formed a new relationship since separating from her husband and maintained contact only with her daughter and grandson. On adaptation, the panel acknowledged she had returned to pre-injury hours but noted the quality of her work had declined - a distinction the original assessor had not weighted.
Those two shifts were enough to tip the balance. The original assessment had five Class 2 ratings and one Class 3, producing a median of 2. The panel's assessment had three of each, pushing the median to 3. The result: an aggregate score of 15 and a base WPI of 15%. After deducting 1% for a pre-existing depressive condition and adding nothing for treatment effect, the panel landed at 14%.
Under the NSW motor accident scheme, 10% WPI is the line in the sand. Below it, an injured person cannot recover damages for pain and suffering. Above it, they can. The original 8% kept the claimant below that line. The panel's 14% puts her well clear of it.
For claims teams handling CTP files in NSW, the case shows how category-level disputes in the impairment rating scale can compound quickly. Two categories moved one class each - from mild to moderate. Neither shift looks dramatic on its own. Together, they flipped the median, changed the aggregate, and transformed the insurer's exposure from statutory benefits to a live claim for non-economic loss.
The panel described its two medical members as "very experienced psychiatrists" and stressed that clinical judgment was the most important tool in applying the rating scale. That framing may make it harder for insurers to challenge similar upgrades on review.
None of this determines what damages the claimant will ultimately recover. But the threshold is cleared, and the file is open.
