Can I claim for concussion after a car accident in NSW?
A car accident may raise a CTP enquiry where head injury or concussion symptoms are medically recorded after the crash. The position depends on accident facts, medical records, symptoms, work impact, insurer decisions and dates.
Permanent impairment assessment
How permanent impairment is assessed for Traumatic brain injury, concussion and post-concussion symptoms
Traumatic brain injury WPI focuses on stable neurological function, not the fact that a head strike or concussion occurred. Concussion symptoms can be real and disruptive, but WPI usually depends on objective assessment of consciousness/awareness, cognition, communication, behaviour, movement, cranial nerve or other neurological function.
What injuries can happen to this body part?
- Concussion or mild traumatic brain injury after a fall, strike, vehicle incident or assault
- Moderate or severe traumatic brain injury with loss of consciousness, post-traumatic amnesia or intracranial pathology
- Post-concussion symptoms such as headache, dizziness, fatigue, memory difficulty, concentration difficulty or vestibular symptoms
- Cranial nerve, balance, gait, movement, language or behavioural changes after head trauma
- Cognitive and emotional changes overlapping with psychological injury, pain, sleep or medication effects
Symptoms and findings that matter
- Acute injury records, imaging and diagnosis
- Glasgow Coma Scale, post-traumatic amnesia and CT/MRI findings where available
- Neuropsychology, neurology, rehabilitation or occupational therapy findings at MMI
- Consciousness/awareness, cognition/memory, language/communication, emotional or behavioural change
- Gait, station, coordination, movement disorder, cranial nerve or vestibular impairment
- Medication, fatigue, sleep and psychiatric overlap
- Whether symptoms are better assessed under another chapter or require legal review
What investigations are usually relevant?
- Treating specialist report and final impairment assessment at maximum medical improvement
- Imaging, pathology, audiology, ophthalmology, respiratory, nerve or functional testing that fits the body system
- Operative reports, discharge summaries, rehabilitation records and objective clinical measurements where relevant
How WPI is assessed for this body part
- Traumatic brain injury WPI focuses on stable neurological function, not the fact that a head strike or concussion occurred. Concussion symptoms can be real and disruptive, but WPI usually depends on objective assessment of consciousness/awareness, cognition, communication, behaviour, movement, cranial nerve or other neurological function.
- Assessment source: NSW Guidelines Chapter 5 nervous system. For traumatic brain injury, the Guidelines require a severe/high-energy head impact context and clinical evidence such as significant verified GCS abnormality, post-traumatic amnesia or significant intracranial pathology.
- The assessor should explain maximum medical improvement, the body-system chapter, the method selected, any NSW modification, and why the objective findings fit that method.
How movement affects the assessment
- ROM is not the main method for traumatic brain injury. Movement and gait may matter if they reflect neurological impairment, balance, coordination or brain injury consequences.
- Neck, shoulder or spine injuries from the same accident should be assessed under their own chapters and not hidden inside a concussion page.
NSW nervous system assessment rules
Brain and central nervous systemCerebral functions are considered by domains such as consciousness/awareness, cognition, communication, emotional/behavioural change, movement and cranial nerve findings.
Peripheral nervesPeripheral nervous system impairment is assessed through the relevant upper extremity, lower extremity or spine method rather than as a vague neurological label.
Do not double-rateThe assessor should be specific and avoid rating the same functional loss under overlapping cognitive, behavioural, musculoskeletal or nerve categories.
Objective evidenceStable clinical findings, specialist examination and relevant testing matter. Symptoms by themselves may affect capacity but may not establish WPI.
NSW traumatic brain injury source checks
Clinical trigger for TBI assessmentFor traumatic brain injury, the NSW Guidelines refer to evidence of severe/high-energy head impact plus at least one of significant verified Glasgow Coma Scale abnormality, significant post-traumatic amnesia, or significant intracranial pathology on CT/MRI.
Neuropsychology contextNeuropsychological testing should be considered with the overall history, examination and radiology; it should not be used in isolation.
Mild symptomsHeadache, fatigue, dizziness or poor concentration after concussion can be real, but WPI requires stable impairment supported by the Guideline method.
Practical WPI examples
- A short-lived concussion with normal imaging and no stable objective deficit may still affect treatment and work capacity, but may not produce ratable WPI.
- A severe TBI assessment may need neuropsychology, neurology, rehabilitation records and evidence about ADL, employment, supervision needs and cognitive reliability.
- Neuropsychological test results should be read with the history, examination and radiology, not as a standalone number.
- Poor concentration may arise from TBI, pain, medication, sleep disturbance or psychological injury; the evidence should explain the cause rather than assume it.
Evidence checklist
- A clear diagnosis and the body area being assessed
- Records showing the condition has reached maximum medical improvement, if that is the issue
- Specialist reports, imaging reports and treating notes relied on by the assessor
- Objective findings on examination, not only symptoms described by the injured person
- A work and treatment chronology explaining the injury, treatment, surgery and recovery path
- Any previous injury, degeneration, congenital issue or non-work cause that needs apportionment considered
- Hospital and emergency notes
- Ambulance records
- GCS and post-traumatic amnesia records
- CT/MRI reports
- Neurologist report
- Neuropsychological testing
- GP notes
- OT/functional assessment
- Rehabilitation notes and return-to-work evidence
What usually does not increase WPI
- Assuming a scan result automatically gives a WPI percentage
- Confusing pain, disability or inability to work with permanent impairment
- Ignoring maximum medical improvement before arranging an assessment
- Using an AMA5 table without checking whether the NSW Guidelines modify or replace it
- Double counting the same impairment through two methods when the Guidelines require one method
- Assuming a normal CT rules out every ongoing problem
- Treating a symptom diary as a substitute for clinical findings
- Equating every concussion symptom with WPI
- Ignoring psychological, vestibular, cervical spine or medication overlap

Request a free claim checkCommon accident contexts
Head injury and concussion enquiries need a careful timeline: impact, immediate symptoms, later symptoms, treatment, work or study effects and any safety concerns. The claim pathway still depends on how the incident occurred.
- Car accident and CTP matters involving impact, whiplash-type forces or later head-related symptoms
- Work injury matters involving falls, falling objects, assaults or machinery incidents
- Slip, trip and fall or public place incidents involving head impact
- TPD enquiries where ongoing symptoms affect sustainable work capacity
Symptoms and treatment records that may matter
Medical records may mention headache, dizziness, nausea, memory issues, concentration problems, light sensitivity, sleep changes, mood changes or fatigue. These symptoms need medical review and should not be self-diagnosed.
Evidence to keep
For head injury or concussion concerns, keep emergency, GP and specialist records, symptom notes, work or study impact records, witness details and incident or accident reports.
- Emergency, GP, hospital, imaging, referral and treatment records
- Accident reports, police or workplace reports, incident records and witness details
- Photos of the scene, hazard, vehicle damage, helmet or damaged items where relevant
- Work capacity records, rosters, payslips and notes about study, driving or daily restrictions
Ask which claim pathway may applyHow the injury may affect assessment
Head injury symptoms can affect work, driving, study, screens, memory, concentration, sleep, treatment and daily routines. Claim evidence should show the effect over time and the medical follow-up.
Common claim problems
These issues do not decide the outcome by themselves, but they are common reasons a claim needs careful evidence and chronology.
- Delayed medical review after head impact
- Symptoms not recorded clearly in early treatment notes
- Insurer questions about whether symptoms are connected to the accident or work event
- Underestimating cognitive, sleep or psychological effects because they are less visible
Mistakes to avoid
Do not treat a head injury as minor just because there is no visible wound. Medical review and a clear symptom timeline matter.
- Continuing as normal without medical review after head injury symptoms
- Relying on memory instead of treatment records and incident reports
- Not recording work, study or driving restrictions
- Assuming concussion by itself proves compensation is available
Claim pathway
How injury evidence is usually organised
This is a general pathway only. The documents, decision-maker and timing can change depending on the facts and claim type.
- 1
Injury or incident
Start with where and how the injury happened: road accident, workplace incident, public or private place, or a longer-term disability situation.
- 2
Medical treatment
Get appropriate treatment and keep certificates, referrals, scans, reports and notes about how symptoms affect work or daily life.
- 3
Evidence and chronology
Organise incident records, photos, witness details, wage records, claim numbers and correspondence in date order.
- 4
Insurer or super fund
The pathway may involve a CTP insurer, workers compensation insurer, public liability insurer or superannuation trustee/insurer.
- 5
Assessment or dispute
The insurer or fund may request material, assess treatment or work capacity, make a decision, or issue reasons that need a careful response.
- 6
Resolution or next decision
The practical outcome may be approval, payment, treatment support, further evidence, review, dispute steps or another decision point.
Documents and records
Injury evidence to organise early
The useful records depend on how the injury happened, when symptoms were recorded and how treatment or work capacity changed.
- Date, location and short description of the injury event
- Medical certificates, reports, scans, treatment records or hospital documents
- Employer, insurer, police, incident or venue records where relevant
- Photos, witness details, dashcam or other supporting material if available
- Income, superannuation, work capacity or leave records where relevant
- Letters, emails, claim numbers and decisions already received
