Understanding claims and cover
When we accept a claim for cover it means there’s been an identifiable accident causing personal injury. Find out more about how we make cover decisions.

About cover
We make cover decisions based on the Accident Compensation Act 2001.
How we make cover decisions based on legislation
We cover a claim when there's a personal injury from an identifiable accident. The link between the client's personal injury and the accident is known as causation.
With simple claims, causation is easy to establish and making a cover decision is quick. If the injury type is more complex or there's a delay in making a claim, establishing causation can take longer.

Sometimes we'll need to ask a specialist to help establish causation. There are pathologies or diagnoses that we don't cover, including conditions caused by the ageing process and pre-existing conditions.
When working with our clients, you'll need to consider whether the support you are providing is for the injury we have covered. The covered injury is identified by a Read code.
Cover and support
If we accept a claim, the client can receive supports they need to recover from their covered injury. Supports may include treatment, weekly compensation, or rehabilitation.
Supports must:
- be necessary
- be appropriate
- be timely
- be of the required quality
- not be excessive in number or duration
- follow evidence-based guidelines.
Change in diagnosis
It's important you tell us of any change in the client's diagnosis as soon as possible. A change in diagnosis could impact the supports they receive, for example a sprain may need different supports over a shorter period than a fracture or break.
Updating or changing a diagnosis
It's also important you tell us of situations where the client needs support that isn't linked to the covered injury so we can work with you to help them further.
Types of claims we cover
We've provided below an overview of straightforward, complex, and other types of injuries we cover, as well as examples.
This is not a definitive list. We assess each claim on its merits, the circumstances of the case, and any underlying conditions the client may have. If in doubt, you should lodge the claim with as much relevant information as possible or refer the client to a medical practitioner who can to allow us to make the appropriate cover decision.
