Minor vs Non-Minor Injury Under MAIA

The Motor Accident Injuries Act 2017 defines a 'minor injury' in a specific legal way. It is not the same as 'you feel fine' or 'it was only soft tissue.' The definition includes particular soft tissue and psychological injury types below a statutory threshold, and insurers make formal decisions using medical reports and sometimes independent examinations.

This page explains why the label matters. It does not tell you which box you fall into — that is for the insurer (and potentially PIC or a court) after looking at evidence.

What changes if you are classified minor

Broadly, a minor injury classification limits how long certain statutory benefits can continue compared with someone who has a non-minor injury. It also affects whether you can pursue common law damages for pain and suffering and economic loss.

Exact time frames and entitlements are in the Act and SIRA publications — they are easier to read with a lawyer sitting beside you.

Who decides — not your Facebook group

The insurer issues a decision based on clinical records, certificates, imaging, and sometimes IME reports. Treating doctors do not 'upgrade' you by writing adjectives; they document diagnoses, examination findings, and functional impact accurately. Lawyers challenge decisions when the evidence does not support the label.

Psychological injuries

Psychological conditions can be minor or non-minor under the statutory definitions, depending on diagnosis and how they sit against the threshold. Insurers may require psychiatric assessment. Our psychology colleagues work within clinical scope; legal arguments about classification sit with solicitors.

If you disagree with 'minor'

You may have review rights. Do not delay — gather updated reports, ensure imaging and specialist opinions are on file, and brief a compensation lawyer if the stakes are high. Medically, we make sure the record reflects ongoing symptoms, restrictions, and treatment response.

What counts as a minor injury under MAIA

The Act defines minor injuries by reference to specific injury types. Broadly, soft tissue injuries — sprains, strains, and whiplash-type injuries — that do not involve certain complications fall into the minor category. A straightforward neck or back strain without radiculopathy, disc herniation confirmed on imaging, or other structural findings will usually be classified as minor.

Minor psychological injuries are also defined in the legislation. A transient stress reaction or adjustment disorder without a more serious underlying condition may be classified as minor. The threshold is not about how much distress you feel — it is about the clinical diagnosis and how it sits against the statutory definition.

The exact wording references specific injury types and exclusions set out in the Act and supporting regulations. SIRA publishes guidance on the definitions, and they are worth reading if you want to understand where the lines are drawn. Your treating doctor can help explain how your diagnosis relates to these categories, but the legal classification decision sits with the insurer (and potentially PIC on review).

How medical evidence influences classification

Detailed clinical notes are the foundation of any classification decision. A GP note that says 'neck pain, soft tissue' gives the insurer very little to work with — and when the insurer has limited information, they tend to default to the simpler classification. Notes that describe the mechanism of injury, specific examination findings, severity, functional impact, and response to treatment over time build a much clearer picture.

Specialist referrals can be important. If your GP suspects something beyond straightforward soft tissue — for example, nerve involvement, a torn ligament, or a more complex psychological condition — a referral to a specialist provides a formal opinion that carries weight with insurers. An orthopaedic surgeon, neurologist, or psychiatrist can provide a diagnosis that may change the classification.

Imaging findings matter, but only when they are clinically correlated. An MRI showing a disc bulge does not automatically make an injury non-minor — the treating doctor needs to explain how that finding relates to the patient's symptoms and examination. Conversely, normal imaging does not prove the injury is minor if the clinical picture is more complicated.

Treatment response documentation is often overlooked. If a soft tissue injury was expected to resolve in six to eight weeks but at four months the patient still has significant pain, restricted movement, and poor function despite appropriate treatment, that pattern may suggest the injury is more complicated than initially thought. Documenting this trajectory over time can support a reclassification argument.

Disputing a minor injury classification

If you believe the insurer's classification is wrong, the first step is gathering the right evidence. Updated clinical notes, specialist opinions, imaging reports, and a clear treatment history showing the injury is more complex than a straightforward soft tissue problem all form the basis of a dispute.

The insurer has an internal review process. You (or your lawyer) can request that the classification be reconsidered in light of new or additional evidence. This is often the quickest path if you have a strong specialist report that was not available when the original decision was made.

If internal review does not resolve the matter, the Personal Injury Commission (PIC) can conduct a medical assessment to determine whether the injury is minor or non-minor. This is a formal process — a PIC-appointed medical assessor examines you and reviews the clinical evidence. Their determination carries significant weight.

Medico-legal reports — detailed reports prepared by medical specialists specifically addressing the classification question — play an important role in disputes. These are different from routine treating reports; they are structured to address the statutory definition and are usually arranged through a lawyer. On the treating side, our role is to make sure the clinical record is thorough, accurate, and up to date so that any medico-legal assessment has good information to work from.
