Key Takeaway: In Western Australia, if a work injury or accident leaves you with a permanent impairment, you may be entitled to a lump sum payout on top of other compensation. The amount depends on your level of whole person impairment and how it is assessed. Withstand Lawyers helps WA claimants pursue their payout on a no win, no fee basis.

WA Permanent Impairment: Quick Answers

What is a permanent impairment payout in WA?
It is a lump sum you can receive when a work injury or accident causes lasting damage that will not fully heal. In Western Australia the payout reflects your degree of whole person impairment, assessed by an approved medical examiner. It is generally separate from payments for lost wages and medical treatment.
How is permanent impairment assessed in WA?
A specially trained doctor examines you once your condition has stabilised and assigns a whole person impairment percentage using recognised medical guidelines. That percentage drives the size of your lump sum. Because the assessment can significantly affect your payout, it is worth getting advice before you are examined so nothing is overlooked.
Can I claim permanent impairment and still receive other compensation?
In many WA claims, yes. A permanent impairment lump sum can sit alongside benefits for medical costs and lost income, and in some cases a separate common law claim. The rules and time limits differ depending on how you were injured, so it helps to have a lawyer map out everything you may be owed.

Did you know that you may be entitled to a permanent impairment payment if you are injured at work or in a motor vehicle accident in Western Australia?

How is the permanent impairment rate calculated?

The permanent impairment rate is calculated by a medical assessment. An independent medical examiner assesses your body by using American Medical Association’s reference books to draft an unbiased and independent medical report. If you have multiple injuries due to the same accident, the doctor will evaluate them separately and add them to obtain your overall permanent impairment rate.

WA Permanent Impairment FAQ

Who can claim a permanent impairment payout in WA?
Workers injured on the job and people hurt in other accidents in Western Australia may be able to claim a permanent impairment lump sum, provided their injury has left a lasting effect. Eligibility depends on the type of claim and the level of impairment. A lawyer can quickly tell you whether you qualify.
When should permanent impairment be assessed?
Assessment usually happens once your condition has reached maximum medical improvement, meaning it is unlikely to change much further. Being assessed too early can understate your impairment and reduce your payout. Your lawyer and treating doctors can help you judge the right time so the assessment fairly reflects your lasting injury.
What does whole person impairment mean?
Whole person impairment is a percentage that describes how much a permanent injury affects your body and function overall. Doctors calculate it using standard medical guidelines. In Western Australia this percentage is central to working out your lump sum, so an accurate, well-supported assessment is very important to the outcome of your claim.
Can I dispute a permanent impairment assessment I disagree with?
Yes. If you believe your impairment has been assessed too low, you can usually seek a further opinion or challenge the assessment through the proper process. Getting legal advice early is important, because time limits apply. Withstand Lawyers can review the assessment and help you pursue a fairer result.
How long do I have to claim permanent impairment in WA?
Time limits apply and they vary depending on how you were injured and the type of claim. Missing a deadline can affect your right to a payout. Because the clock often starts from the date of injury or when impairment is confirmed, it is wise to get advice as soon as you can.
Does a permanent impairment payout affect my other benefits?
It can. Receiving a lump sum may interact with ongoing weekly payments or a later common law claim, depending on your circumstances. Some choices you make can close off other options, so it is important to understand the trade-offs first. A lawyer can explain how a payout fits with your other entitlements.
Do I need a lawyer to claim permanent impairment in WA?
You are not required to, but permanent impairment claims involve medical assessments, strict time limits and rules that can significantly change your payout.
