Injury compensation lawyer Bass Hill: threshold and beyond

Most people never need to think about impairment percentages. If your injury is serious, you probably will. The scheme's rules divide injuries by type first, threshold or not, and then, for some entitlements, by the degree of lasting impairment. This page explains both in general terms. Your own claim depends on your diagnosis and on the insurer's decisions, which can be reviewed.

Impairment is generally assessed once an injury has stabilised, meaning it's unlikely to change much with further treatment. Assessing too early can understate a serious injury. The insurer may arrange an assessment, your own doctors may give opinions, and if the insurer and you disagree about the degree of impairment, the Personal Injury Commission can carry out a medical assessment.

• How complete and current your medical records are
• Scans or tests your doctors have ordered
• Whether you disagree with the result, and the deadline to say so

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, the opinion of a treating psychiatrist or psychologist can matter a great deal.

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.

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.

An assessment above 10% opens damages for non-economic loss and changes some timing rules as well. But many people with genuine, lasting injuries are assessed at 10% or less. That doesn't mean the injury isn't real, or that there is no damages claim. Economic loss, such as lost earning capacity, can still be claimed where the other conditions are met.

Earning capacity compares what you could have earned without the injury with what you can realistically earn now. For a tradesperson with a damaged shoulder, or an office worker with a brain injury, that gap can be large and long-lasting. Record every change to your working life: hours, duties, roles you can no longer do. Those facts sit alongside the medical evidence.

Because serious injuries take time to show their full effect, evidence builds in layers. Early records show the injury happened and how bad it was. Later reports show how it has settled and what it has left behind. An independent lawyer can help spot gaps, but the underlying evidence comes from your treatment. Getting good care is also how good evidence is made.

• Imaging reports, such as X-ray, CT or MRI, where done
• Operation and specialist reports
• Records of how the injury affects your work
• Any impairment assessment, and your response to it
