Injury compensation lawyer Ultimo: impairment explained

An injury can be serious in human terms and still sit on the threshold side of the line, and the reverse can happen too. That can feel unfair. It helps to know the scheme's tests are about the type of injury and its lasting effects, not how much you've suffered. Knowing which test applies helps you focus on the evidence that matters.

The definition works by exclusion. An injury is generally threshold if it is soft tissue damage with no nerve damage and no torn tendon, ligament, meniscus or cartilage, whether the tear is complete or not, or if it is a psychological injury the scheme classes as threshold. Injuries outside that description, such as fractures, torn ligaments or brain injuries, are generally more than threshold.

Which side you're on matters. For accidents from 1 April 2023, statutory benefits for a threshold injury generally last up to 52 weeks. For accidents between 1 December 2017 and 31 March 2023, the limit was 26 weeks. If your injury is more than threshold and you weren't mostly at fault, benefits can generally continue for longer, and a damages claim may be possible.

The scheme treats psychological injury seriously, but it still sorts it by diagnosis. A threshold psychological injury is generally handled like a threshold physical one. A more serious diagnosed condition may take the claim beyond the threshold. Because the difference turns on the diagnosis, what is on record, and when it was recorded, can matter a great deal.

A serious injury can change more than the next few months of work. It can limit the kind of work you can do for years, or permanently. In a damages claim, that is called loss of future earning capacity, and it can be a significant part of a serious injury claim. It generally needs medical evidence, your work history and sometimes vocational experts.

People are often surprised by how technical WPI is. It is assessed under guidelines that rate specific impairments, such as lost movement in a joint, and express the result as a whole-body percentage. More than 10% is the key line in CTP claims, because damages for non-economic loss, meaning pain and suffering, are only available above it. Loss of earnings doesn't need that level.

Because so much can turn on a few percentage points, WPI assessments are often contested. Reports prepared for you, for the insurer and, if there's a dispute, by a medical assessor through the Personal Injury Commission may reach different figures. Keep every report, and get advice before accepting an assessment you think is wrong.

In a serious injury claim, impairment often comes into focus well after the crash, once the injury has stabilised. The Personal Injury Commission handles medical assessment where the insurer and the injured person disagree. If you think an assessment is wrong, the steps to challenge it are set out separately, and the deadlines are short, so act promptly.

• Whether the injury has stabilised
• How complete and current the evidence is
• Any assessment already made, and its date

Serious injury claims rest on evidence gathered over time: records made from the day of the crash, reports on the injury as it develops, and later assessments of what it has left behind. Your own records add the human detail. Start collecting early, keep everything in date order, and make sure every injury is on the record, not just the worst one.

• Every insurer decision about the injury, with its date
• Any reports prepared for the claim
• Every Certificate of Fitness, in order
• Any impairment assessment, and your response to it
