Whole Person Impairment Assessments
Workers who suffer a work-related injury or illness that leads to a permanent impairment may be entitled to a Whole Person Impairment (WPI) assessment as part of their workers’ compensation claim. This assessment determines the extent of an injured worker’s impairment percentage, which directly impacts their eligibility for lump sum compensation, weekly payments, and medical and related expenses.
At Lex Medicus, our team of independent medical examiners provides medico-legal assessments to ensure fair evaluations for those seeking a whole person impairment claim. If you need an expert medical assessment for your permanent impairment claim, we offer detailed medical reports that support your case.
What is Whole Person Impairment?
Whole Person Impairment (WPI) refers to the permanent loss, damage, or reduced function of a part of the body, bodily system, or mental capacity due to a work-related injury or illness. It includes both physical and psychological impairments, impacting an individual’s ability to work and perform daily activities.
The whole person impairment rating is a key factor in determining an individual’s entitlement to a lump sum payout under various workers’ compensation schemes across Australia. Each state and territory has its own workers’ compensation guidelines, but in most cases, an injured worker with a physical injury must have a person impairment percentage of more than 21% or more to qualify for a permanent impairment payout.
For individuals who have sustained primary psychological injuries, the threshold for impairment is generally higher, typically set at 21% or more. Some jurisdictions provide special considerations for emergency service workers, allowing them to qualify for compensation benefits with a lower impairment percentage.
Once the final assessment is complete, a whole person impairment percentage is assigned based on the whole person impairment table used in the respective state or territory. This rating is then used to determine the appropriate compensation claims, which may include a lump sum payment, weekly payments, coverage for medical treatment, and related expenses.
How is Whole Person Impairment Calculated?
The calculation of Whole Person Impairment (WPI) in Australia adheres to standardised guidelines outlined in the Evaluation of Permanent Impairment framework. This process is initiated once an injured worker’s condition has reached Maximum Medical Improvement (MMI), indicating that the injury has stabilised and is unlikely to change significantly with or without medical treatment.
Qualified medical practitioners conducts the impairment assessment, evaluating factors such as the extent of permanent impairment, the level of WPI, and the influence of any prior injuries or pre-existing conditions. The assessment relies on objective criteria specified in the approved guidelines, ensuring a consistent and equitable evaluation of impairment across cases.
It’s important to note that while the assessment provides a WPI percentage, this rating is distinct from a disability rating. The WPI focuses on the medical evaluation of impairment, whereas disability assessments consider the broader impact on an individual’s personal, social, and occupational life.
In summary, the WPI calculation in Australia is a methodical process conducted by medical professionals following established guidelines, ensuring that injured workers receive fair and accurate assessments of their permanent impairments.
Compensation Entitlements Based on Whole Person Impairment Rating
A worker’s person impairment percentage directly impacts the level of weekly compensation payments, medical treatment, and lump sum benefits they are entitled to receive. The compensation structure is as follows:
Workers with a 0-10% WPI rating may be eligible for weekly compensation payments for up to 130 weeks, with a possible extension to 260 weeks if they meet specific criteria. Those with an 11-20% WPI rating may receive weekly payments for up to five years, including coverage for medical and related expenses.
For individuals with a 21% or higher person impairment rating, additional long-term benefits may apply. These workers are typically entitled to lifetime medical coverage, ensuring access to medical expenses, therapies, and treatments for as long as necessary. Weekly payments may also continue until they reach retirement age, offering sustained financial support.
Who Can Conduct a Whole Person Impairment Assessment?
A Whole Person Impairment (WPI) assessment must be conducted by a qualified medico-legal specialist, such as an independent medical examiner with expertise in evaluating permanent impairment from a compensable injury. These assessments are carried out by medical practitioners trained in assessing both physical and psychological injuries, ensuring that findings are objective, evidence-based, and aligned with compensation guidelines.
Can Psychologists Assess Whole Person Impairment?
No, Whole Person Impairment (WPI) assessments cannot be conducted by a general practitioner, physiotherapist, psychologist, or other treatment provider. The degree of permanent impairment must be assessed by an independent medical specialist with the appropriate qualifications and accreditation to perform impairment evaluations.
For psychological injuries, a psychiatrist—not a psychologist—must conduct the assessment using the Psychiatric Impairment Rating Scale (PIRS). While psychologists provide valuable insights into mental health conditions, their assessments serve as supporting evidence rather than the primary basis for determining WPI in compensation claims.
