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.

SIRA’s Dispute Resolution Service (DRS) delivers independent dispute  resolution services for disputes between insurers and injured people in the CTP Green Slip Scheme. This includes disputes related to injuries sustained in accidents that occurred on or before 30 November 2017  assessed at the Medical Assessment Service (MAS) and the Claims Assessment and Resolution Service (CARS).

Either the injured person (or their legal representative) or the insurer can make an application to DRS for resolution of a medical dispute. Then the other party will have a chance to reply to that application.

The medical dispute resolution process

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

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

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

We will advise you  of all the medical assessment details (eg medical decision maker’s name, location of any examination, date and time).

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

After the examination is finished, the medical decision maker will consider all the available documentation and make a decision about your dispute.

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 of the appointment.

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


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

If you don’t turn up  or make a cancellation with less than 1 weeks’ notice, you may be required to pay a cancellation fee. Please contact us as soon as possible if you need to cancel.
