If you have suffered a workplace accident or injury in Queensland, you may be required to undergo a Degree of Permanent Impairment (DPI) assessment as part of your workers’ compensation claim.
A DPI assessment is an important step in determining whether a worker may have an entitlement to statutory lump sum compensation and may also affect decisions regarding common law rights and available compensation pathways. For many injured workers, the assessment process occurs after a period of treatment and rehabilitation when their condition has stabilised.
Understanding how permanent impairment assessments work, what a DPI percentage means, and what happens after you receive a Notice of Assessment can help you make informed decisions about your compensation entitlements. Explore our guide on the assessment of the degree of permanent impairment in Queensland and get in touch with an L&H Injury Lawyer for situation-specific legal advice.
What Is Permanent Impairment?
Permanent impairment refers to the lasting effects of a work-related injury or illness that remain after reasonable medical treatment and rehabilitation have reached a stable and stationary position.
A permanent impairment does not necessarily mean a person is unable to work. Rather, it is a medical assessment of the extent to which an injury has permanently affected bodily function, movement, psychological functioning, or overall health.
Permanent impairments may arise from a wide range of workplace injuries, including:
- Orthopaedic injuries
- Spinal injuries
- Amputations
- Neurological injuries
- Hearing loss
- Respiratory conditions
- Psychological injuries
The extent of permanent impairment is typically expressed as a percentage known as the Degree of Permanent Impairment (DPI).
What Does a DPI Percentage Mean?
The Degree of Permanent Impairment is a medical assessment that reflects the level of permanent functional loss resulting from a workplace injury.
The higher the DPI percentage, the greater the assessed level of permanent impairment.
For example:
- A 0% DPI indicates no assessable permanent impairment.
- A low DPI percentage may indicate relatively minor permanent functional loss.
- Higher DPI percentages may reflect more significant and ongoing impairments.
Importantly, a DPI percentage is not the same as a person’s level of disability, incapacity for work, or future financial loss.
A worker’s compensation entitlements may depend on a range of factors beyond the DPI assessment alone, including medical evidence, employment circumstances, loss of income, treatment requirements, and the nature of the claim being pursued.
Maximum Medical Improvement (MMI)
Before a permanent impairment assessment can usually occur, a worker’s condition will generally need to be considered stable and stationary, meaning it has reached a level of recovery where any permanent impairment can be assessed. This is generally known as Maximum Medical Improvement (MMI).
MMI is a term used by medical practitioners, and it refers to the point at which a worker’s condition has stabilised and is not expected to substantially improve with further treatment.
This does not mean a worker has fully recovered. Rather, it means that medical practitioners consider the injury has reached a level of stability that allows a permanent impairment assessment to be conducted.
Evidence commonly used to determine MMI may include:
- Treating specialist reports
- Rehabilitation records
- Imaging results
- Medical assessments
- Treatment histories
It is often important to discuss MMI with treating doctors and specialists before proceeding with a DPI assessment.
The Degree of Permanent Impairment Assessment Process
Once a worker has reached MMI, an impairment assessment may be arranged. The assessment process differs depending on whether the injury is physical or psychological.
For many physical injuries, the assessment is conducted by an appropriately qualified independent medical specialist with expertise relevant to the worker’s injury or condition. This may include:
- Orthopaedic surgeons
- Neurologists
- Occupational physicians
- Psychiatric specialists
- Other medical specialists
During the assessment, the medical practitioner may review:
- Medical records
- Specialist reports
- Imaging and diagnostic results
- Treatment history
- Functional limitations
- Current symptoms
The assessor applies approved evaluation methods to determine the worker’s degree of permanent impairment. Following the assessment, a detailed medical report is typically prepared outlining the findings and the assigned DPI percentage.
For psychological and psychiatric injuries, a different process applies under the Queensland workers’ compensation scheme. Where a worker has sustained a psychiatric or psychological injury, the insurer is generally required to refer the matter to the Medical Assessment Tribunal (MAT) for assessment of permanent impairment. The MAT is responsible for determining the Degree of Permanent Impairment for psychological injuries and issuing its assessment in accordance with the legislative framework.

Psychological Injuries and the Medical Assessment Tribunal
Psychological and psychiatric injuries are assessed differently from many physical injuries under the Queensland workers’ compensation scheme.
Where a worker has sustained a compensable psychological or psychiatric injury, the assessment of permanent impairment is undertaken by the Medical Assessment Tribunal (MAT). Unlike physical injuries, which are assessed by independent medical specialists, psychological injury assessments for permanent impairment purposes are referred to the MAT in accordance with the legislative requirements.
The Tribunal may consider a range of evidence when determining permanent impairment, including:
- Psychiatric reports
- Psychological treatment records
- Treating practitioner records
- Rehabilitation information
- Relevant medical evidence
- Information regarding the worker’s functional capacity
Psychological injury claims can involve complex medical and evidentiary issues. For this reason, comprehensive and accurate medical evidence is important when the Tribunal considers the nature and extent of any permanent impairment.
Workers who receive a Notice of Assessment relating to a psychological injury may benefit from obtaining legal advice about the implications of the assessment, any available compensation options, and the effect the assessment may have on future entitlements.
Notice of Assessment (NOA): What Happens Next?
After a Degree of Permanent Impairment assessment has been completed, WorkCover Queensland or the relevant self-insurer may issue a Notice of Assessment (NOA).
The Notice of Assessment typically sets out:
- The assessed Degree of Permanent Impairment (DPI)
- Any statutory lump sum compensation offer
- Information about available options and elections
- Applicable response deadlines and statutory timeframes
For many injured workers, the Notice of Assessment is one of the most significant stages of the workers’ compensation process. Decisions made after receiving a NOA can affect both immediate compensation entitlements and potential future rights, including whether a common law claim may be pursued in certain circumstances.
Strict statutory time limits apply once a Notice of Assessment has been issued. Failing to respond within the required timeframe may affect the options available to a worker under the Queensland workers’ compensation scheme.
Before accepting a lump sum offer, making an election, or otherwise responding to a Notice of Assessment, it is highly recommended to obtain legal advice. Understanding the potential consequences of each available option can help ensure informed decisions are made based on the specific circumstances of the claim.
Relevant considerations may include:
- The assessed DPI percentage
- The nature and extent of the injury
- Available medical evidence
- Future treatment and rehabilitation requirements
- Potential common law rights
- The long-term impact of any election or compensation decision
Because the consequences of a Notice of Assessment can be significant, obtaining advice before making a decision may assist workers in protecting their legal rights and understanding the compensation pathways available to them.
Can a Degree of Permanent Impairment Assessment Be Challenged?
The options available to challenge a Degree of Permanent Impairment (DPI) assessment depend on the type of injury involved and the assessment process used.
For many physical injury assessments, Queensland workers’ compensation legislation provides a mechanism for a worker to dispute the assessment and seek a further medical assessment. Strict time limits apply, and any request for reassessment must generally be made promptly after the assessment has been received.
Psychological and psychiatric injuries are treated differently. Where permanent impairment has been assessed by the Medical Assessment Tribunal (MAT), the Tribunal’s medical decision is generally final and binding under the legislative framework.
This means a worker cannot ordinarily seek a review or appeal simply because they disagree with the percentage of permanent impairment assessed by the Tribunal.
In limited circumstances, legal avenues may exist where there are issues relating to procedural fairness or questions of law. However, these processes are separate from a medical reassessment of the impairment percentage itself and can be complex.
Because strict time limits may apply to some assessment disputes and because the available options can differ significantly depending on the type of injury involved, obtaining legal advice promptly may assist workers in understanding their rights and available options.
Degree of Permanent Impairment Thresholds and Common Law Elections
For many injured workers, the most important question after receiving a Notice of Assessment is how their Degree of Permanent Impairment (DPI) may affect their future compensation options.
The DPI percentage assigned during a permanent impairment assessment can have significant implications under the Queensland workers’ compensation scheme. In addition to determining whether a statutory lump sum compensation offer may be available, the assessed DPI may also affect the options available to a worker when considering future compensation pathways.
After receiving a Notice of Assessment, a worker may be required to make an election regarding the available options under the legislation. The decision made at this stage can have important consequences and may affect future legal rights.
Common questions injured workers often have include:
- What does my DPI percentage mean?
- Am I eligible for a statutory lump sum payment?
- Can I pursue a common law claim?
- Will accepting a lump sum compensation offer affect my future rights?
- What are the consequences of the election I am being asked to make?
The answers to these questions will depend on the individual circumstances of the claim, including the nature of the injury, the assessed DPI percentage, the available medical evidence, and the applicable legislative requirements.
Because an election made following a Notice of Assessment can have long-term consequences, it is important to fully understand the available options before making a decision. Obtaining legal advice at this stage can assist workers in understanding how a DPI assessment may affect their compensation entitlements and any potential common law rights.
Lump Sum Compensation and Common Law Claims
A DPI assessment may lead to an offer of statutory lump sum compensation.
The statutory lump sum amount is generally determined by reference to the assessed DPI percentage and the applicable legislative framework.
However, accepting a statutory lump sum offer may affect a worker’s future legal rights and compensation options.
In some circumstances, an injured worker may also have an entitlement to pursue common law damages against a negligent employer.
Common law claims may allow recovery for losses that can include:
- Past economic loss
- Future economic loss
- Medical and rehabilitation expenses
- Care and assistance requirements
- General damages (which may compensate for pain, suffering and loss of amenities of life)
The most appropriate pathway will depend on the individual facts of the claim, available evidence, liability considerations, and the worker’s circumstances.
Because important legal rights may be affected, it is advisable to obtain legal advice before making an election regarding a Notice of Assessment.
How Is Compensation Calculated?
There is no single formula that determines how much compensation an injured worker may receive.
For statutory compensation claims, lump sum entitlements are generally linked to the assessed DPI percentage.
For common law claims, compensation may depend on a range of factors, including:
- The nature and severity of the injury
- Medical evidence
- Future treatment requirements
- Past and future loss of earnings
- Capacity for future employment
- Care and support needs
- Rehabilitation requirements
Comprehensive evidence is required to properly assess the value of a common law claim. This evidence may include medical records, specialist reports, employment records, rehabilitation evidence, taxation records and expert opinions.
Timeline After Reaching Maximum Medical Improvement
While every claim is different, the process may generally involve:
- Reaching Maximum Medical Improvement.
- Attending a permanent impairment assessment.
- Receiving an assessment report.
- Receiving a Notice of Assessment.
- Considering available compensation options.
- Obtaining legal advice if required.
- Accepting, rejecting, or otherwise responding to the Notice of Assessment within the applicable timeframe.
When Should You Seek Legal Advice?
Many workers first seek legal advice after receiving a Notice of Assessment or when they disagree with an impairment assessment outcome.
Legal advice may assist with:
- Reviewing DPI assessment findings
- Explaining Notice of Assessment options
- Assessing statutory compensation entitlements
- Identifying potential common law rights
- Gathering additional medical evidence
- Managing review or dispute processes
The decisions made following a permanent impairment assessment can have long-term implications for compensation entitlements. Understanding the available options before responding to a Notice of Assessment may help ensure informed decisions are made based on the individual circumstances of the claim.
Understanding the DPI Assessment Process
1. Your Injury Reaches Maximum Medical Improvement
Before a Degree of Permanent Impairment (DPI) assessment can occur, your workplace injury will generally need to reach what is known as maximum medical improvement (MMI). This means your treating doctors consider your condition to have stabilised and that further treatment is unlikely to result in substantial improvement.
This does not necessarily mean you have fully recovered. Rather, it means your long-term level of impairment can be assessed.
2. Your Permanent Impairment Is Assessed
Once your condition has stabilised, an assessment may be arranged to determine the extent of any permanent impairment resulting from your work-related injury.
For physical injuries, the assessment is typically conducted by an appropriately qualified independent medical specialist trained in the Queensland workers’ compensation assessment process.
For psychological injuries, the assessment process differs. These matters are generally referred to the Medical Assessment Tribunal (MAT), which determines the degree of permanent impairment under Queensland workers’ compensation legislation.
3. You Receive a Notice of Assessment
After the assessment process is completed, WorkCover Queensland or the relevant self-insurer may issue a Notice of Assessment (NOA).
The Notice of Assessment outlines:
- Your assessed Degree of Permanent Impairment (DPI)
- Any statutory lump sum compensation entitlement
- Important information about your legal rights and available options
Importantly, strict time limits apply once a Notice of Assessment is issued.
4. Consider Your Compensation Options
For many injured workers, receiving a Notice of Assessment can involve important legal decisions that may affect future compensation rights.
In broad terms:
- Workers assessed with a DPI of less than 20% may need to choose between accepting a statutory lump sum payment or preserving their ability to pursue common law damages against a negligent employer.
- Workers assessed with a DPI of 20% or greater may have access to both a statutory lump sum payment and the ability to pursue a common law claim, subject to the requirements of the legislation.
The decision made following a Notice of Assessment can have significant legal consequences. Obtaining legal advice before making an election can assist workers to understand how their decision may affect their compensation entitlements.

Degree of Permanent Impairment Assessment QLD: FAQs
Is a DPI assessment mandatory?
In many workers’ compensation matters, a permanent impairment assessment forms part of the process used to determine statutory compensation entitlements. The specific requirements will depend on the circumstances of the claim.
Can I work and still have a permanent impairment?
Yes. A person may continue to work while still having a medically assessed permanent impairment.
Can a DPI assessment be reviewed?
It depends on the type of injury and how the assessment was conducted. For many physical injury assessments, a worker may have the right to dispute the assessment and seek a further medical assessment within the applicable statutory timeframe. Different rules apply to psychological and psychiatric injuries assessed by the Medical Assessment Tribunal (MAT), whose medical decisions are generally final and binding. Because strict time limits can apply, workers should obtain advice promptly if they are considering challenging an assessment outcome.
Does a higher DPI percentage automatically mean higher compensation?
Not necessarily. While DPI percentages may affect statutory lump sum compensation, common law damages are assessed using a broader range of factors and evidence.
Should I obtain legal advice before responding to a Notice of Assessment?
Many workers choose to obtain legal advice before responding to a Notice of Assessment because the decision made may affect future compensation rights and available legal options.
