Injured worker calculating whole person impairment lump sum

What’s a whole person impairment payout? And why is it so important to make a permanent impairment claim?

A whole person impairment payout is a lump sum payment to compensate you for the overall effect your work injury has had on your life. This lump sum payout is in addition to any weekly payments, medical and related expenses that you may have received.

You must have 11% or more whole person impairment for a physical injury or 15% or more for a primary psychological injury to be entitled to receive a whole person impairment payout in NSW.

For emergency services workers, the threshold reduces to 1% for physical injuries but is still 15% for psychological injuries.

Once you’ve received a whole person impairment payout, it doesn’t put an end to any weekly benefits you’re entitled to – these payments will continue as long as you qualify for them.

Tip: Why is it so important to claim?

It’s super-important to pursue a permanent impairment claim if you qualify. The length of time the insurer is required to pay for your treatment costs is dependent on your level of whole person impairment (WPI). If your level of WPI hasn’t been assessed, the insurer will pay for treatment for at least two years from the date of your injury or two years from the last date you received weekly benefits (whichever is later).

However, once your level of WPI is assessed, this entitlement will be extended according to the table below:

Your level of whole person impairment (%)Entitlement period
0-10% whole person impairmentTwo years from the date of your injury or two years from the last date you received weekly benefits (whichever is the latter).
11-20% whole person impairmentFive years from the date of your injury or five years from the last date you received weekly benefits (whichever is the later).
21% whole person impairment and overLifetime coverage.

0-20% – wages benefits capped at 5 years

21% plus – wages benefits entitlement continues to age 68

What’s the whole person impairment scale?

The whole person impairment (WPI) scale is a rating system used to measure the amount of permanent damage caused by your injuries. It’s based on the loss, or loss of use of any part of your body, or any part of your bodily system or function. Injuries that lead to whole person impairment can be physical or psychological.

What are some examples of impairment ratings?

Here are some examples of common injuries and surgical procedures and the associated whole person impairment NSW ratings:

Injury/ ProcedureApproximate Impairment Rating

How do you calculate whole person impairment in NSW?

Whole person impairment in NSW is calculated by a doctor who assesses your injuries according to the NSW Compensation Guidelines for Evaluation of Permanent Impairment.

The doctor can’t combine both physical and psychological injuries to determine your level of whole person impairment – your compensation is based on your primary injury only (physical or psychological). The doctor also considers your medical history and all available relevant medical information.

The doctor must be accredited as a SIRA-approved assessor, and your workers compensation lawyer will arrange your assessment directly with the doctor. If your WPI is expected to be 21% or more, the insurer is likely to pick their own doctor to do your assessment, as this level of impairment means you’re entitled to compensation for lost wages for five years.

What sort of injuries cause permanent impairment?

The following permanent impairment table of injuries and procedures gives some examples:

Physical injuries:

Injury/ ProcedureDescription
Disc bulgesAlso referred to as sciatica
SurgerySuch as joint replacement and spinal surgery
Hearing lossWhere the hearing loss is work-related
Ankle or wrist fusionFusion results in loss of joint mobility
Multiple injuriesInjures that affect multiple body parts
Knee, elbow and shoulder injuriesWhere range of movement is restricted
Eye injuriesWhere eyesight is impacted
Nerve damageWhere the cause is work-related

Psychological injuries:

The whole person impairment psychological injury assessment is based on an examination done by a psychiatrist who is trained in this assessment method.

A psychiatric disorder is considered permanent if the psychiatrist determines it’s likely to continue indefinitely. The psychiatrist will consider:

For psychological injuries or conditions to reach the permanent impairment rating payout threshold, the condition needs to affect your concentration and your ability to work and care for yourself. Post-Traumatic Stress Disorder (PTSD) is a condition that often reaches this threshold.

What happens at a whole person impairment assessment?

The doctor who does your assessment will look at the following criteria:

After completing your assessment and answering these questions, the doctor will determine your whole person impairment percentage using the tables, graphs and methodology given in the guidelines.
