Medical disputes

The Medical Assessment Service (MAS) can help if there’s been a claim for compensation following a motor vehicle accident but the injured person and the insurer can’t agree on something to do with permanent impairment or medical treatment.

MAS delivers independent dispute resolution services for accidents before 1 December 2017.

Either the injured person or the insurer can make an application to the MAS for resolution of a medical dispute. Then the other party will have a chance to reply to that application.

This is general information only; we know everyone’s situation is different and can be complex. That’s why we encourage you to call us on 1800 34 77 88 and we can talk you through which form best suits your needs.

The medical assessment process

After we receive your application or reply form we will review it and in most cases allocate it to a MAS medical assessor so they can carry out a medical assessment and possibly an examination.

A medical assessor is an independent health practitioner with expertise in conducting medical assessments and determining medical disputes relating to motor accident claims.

Depending on your injuries, you may need to attend more than one medical examination.

We will send you a letter with all the medical assessment details (eg medical assessor’s name, location of any examination, date and time).

If you can’t attend, contact us immediately (if you don’t turn up, or make a late cancellation, you might be charged a fee).

After the examination is finished, the medical assessor will consider all the available documentation and make a determination.

They will provide a certificate setting out their decision and the supporting reasons.  In most cases the certificate and reasons will be sent within three weeks after the appointment.

Everyone’s situation is different.  We encourage you to contact us and we can talk you through any questions you might have. You can also read these fact sheets:


You are not charged for attending a medical assessment examination appointments.

The insurer must pay a claimant's reasonable expenses (including travel expenses) to attend a medical assessment examination.

If you fail to attend or make a cancellation with less than 72 hours' notice, you may be required to pay a cancellation fee. So please contact us as soon as possible if you need to cancel.
