Can I make a second claim for lump sum compensation for permanent impairment?

The assessment of whole person impairment is now vitally important as it effects all entitlements to workers compensation under the Act.

The Workers Compensation Act allows an injured worker to make only one claim for lump sum compensation for permanent impairment if the claim was made after 19 June 2012. You cannot return and try to increase the assessment of whole person impairment once the claim has been made.
Often injuries deteriorate over time or an injured worker may require further surgery some years after the initial injury and this may increase the level of whole person impairment.

However, if you have already obtained an assessment of whole person impairment the Workers Compensation Act prevents you from returning and trying to claim an increase in the level of whole person impairment.

Duration of Medical Expenses Coverage

Medical expenses are payable for a maximum of either two or five years (after the last day on which you receive weekly payments of compensation) unless you have a whole person impairment of 21% or greater.

What is 21% permanent impairment?

In NSW workers compensation, a 21% permanent impairment (PI) refers to a lasting impact on your whole body’s ability to work, assessed by a qualified medical professional. This rating signifies a moderately severe injury with limitations in your work capacity. Here’s what a 21% PI generally entails:

  • Weekly Payments: You might be entitled to ongoing weekly compensation payments beyond the usual five-year limit, subject to your ability to work.
  • Lump Sum Payment: You may be eligible for a lump sum compensation amount based on the assessed impairment level.
  • Medical Treatment: You’ll likely continue receiving medical treatment, rehabilitation, or other support services related to your injury.
  • Work Injury Damages Claim: you may be able to sue your employer for negligence

Criteria for Work Injury Damages Claims

You are unable to make a claim for Work Injury Damages (a negligence claim against your employer) unless your whole person impairment is 15% or greater.

It is important not to make any claim for whole person impairment unless you are satisfied that your injury is unlikely to deteriorate further, or you are satisfied that you will exceed 21% whole person impairment.

If you exceed 21% whole person impairment this entitles you to ongoing payments of weekly compensation until retirement age (subject to the insurer conducting work capacity assessments every 2 years) and payment of medical expenses for life.  It also allows you to investigate whether you may have a claim for Work Injury Damages, that is, a negligence claim against your employer.

What is 15% whole body impairment?

A 15% whole body impairment (WBI) indicates a lasting restriction on your overall work capacity. However, the limitations are typically considered less severe than a 21% rating.
Here’s what a 15% WBI might involve:

  • Weekly Payments: You’re generally entitled to weekly compensation payments for a maximum of five years.
  • Lump Sum Payment: You may be eligible for a lump sum compensation amount based on the assessed impairment level.
  • Medical Treatment: You’ll likely receive medical treatment and support services related to your injury up to a maximum of 5 years from when the weekly payments stop.
  • Work Injury Damages Claim: you may be able to sue your employer for negligence

Importance of Strategic Claim Planning

At Garling and Co we are starting to receive many enquiries from people who have seen a Lawyer and have had their whole person impairment assessed without considering that they only have one chance to make a claim for lump sum compensation.

Considerations Before Claiming Lump Sum Compensation

If you have obtained an assessment of whole person impairment of 14% or less, this will prevent you from making a claim for Work Injury Damages and you can only receive weekly payments for a maximum of 5 years and medical expenses for a maximum of 5 years thereafter.

It is therefore a very important decision to make as to when to make a claim for lump sum compensation and how this decision will affect you rights to ongoing weekly compensation and medical expenses and whether or not you can make a claim for Work Injury Damages.

You should ensure that this decision is not made lightly and that your Lawyer discusses with you the ramifications of what will happen to your future entitlements to workers compensation should you not obtain an assessment of 15% or 21% whole person impairment.

Having said that, it may be possible to make a further claim for lump sum compensation for whole person impairment in certain circumstances.

Reconsideration of Workers’ Compensation Decisions

Section 350(3) of the 1998 Act allows for a Certificate of Determination to be set aside or rescinded by the Workers Compensation Commission.

The Workers Compensation Commission considered in the matter of Samuel v Sebel that a Certificate of Determination may be set aside in consideration of the following:

  1. The Section gives the Commission a wide discretion to reconsider its previous decisions.
  2. While the discretion is a wide one it must be exercised fairly and with due regard to relevant considerations including the reasons for any delay in bring the application for reconsideration.
  3. One of the factors to be weighed in deciding whether to exercise the discretion is the public interest that litigation must not proceed indefinitely.
  4. Reconsideration may be allowed if there is new evidence that could not with reasonable diligence have been obtained at the first decision and is later obtained and that new evidence, if it had been put before an doctor on the first occasion, would have been likely to lead to a different result.
  5. A mistake or oversight by a legal adviser will not give rise to a ground for reconsideration.
  6. The Commission has a duty to do justice between the parties in accordance with the substantial merits of the case.

In taking all those matters into consideration the Commission may decide to rescind or set aside a previous Certificate of Determination assessing the level of whole person impairment if it is in the interest of justice to do so.

This may include cases where there has been a significant deterioration of a worker’s condition that was not foreseen previously or where a worker has sustained a subsequent consequential injury and would be entitled to additional lump sum compensation.

It is certainly a Section which will be looked at over the next few years to determine whether injured workers can return for a second assessment of whole person impairment under Section 350 of the Act.

I was referred to Garling & Co Lawyers, after previously retaining another law firm who failed to progress my matter for a period verging on three years.This was extremely frustrating and damaging,... causing me a lot of unnecessary stress and unreasonable delays. After my first conference with Matthew, he understood the challenges that I had faced and that I wanted to resolve my matter with the defendant reasonably and in a timely manner.My matter was resolved at mediation and during the process, Matthew and Dallas Morgan (barrister), professionally communicated the procedure to me and they negotiated a reasonable settlement, that I was comfortable in accepting.Thank you to Matthew and Allison for being patient with me during the most challenging time of my life. I can now move on with my life and heal. Had I not retained Garling & Co Lawyers, I highly doubt my matter would ever have been resolved.read more
