Yes. An insurer can dispute any part or your entire claim.

When disputing your claim the insurer under Section 74 of the Workers Compensation Act must provide you a written notice of the reasons why the claim is declined and provide a copy of all medical evidence and other documents that they rely upon in declining your claim.

A claim could be declined for the following reasons:

• The insurer does not believe you are injured at work
• The insurer does not believe the injury is any longer work related
• The insurer believes you have recovered from your injury and can return to work
• The insurer does not believe the medical treatment you have requested is reasonable or necessary
• The insurer has medical evidence which states that your injury is not work related

The insurer cannot stop payments of weekly compensation until they have provided you with a written notice of the reasons the claim is declined.
