Certificate of capacity

What is a WorkCover certificate of capacity?

A certificate of capacity is a document that describes your injury or illness.

It provides an opinion on your capacity to work and any limitations that you have on performing your work tasks.

You need a certificate of capacity if you are making a WorkCover claim and that claim includes a claim for weekly payments.

You also need a certificate of capacity if you have an accepted WorkCover claim and you wish to obtain WorkCover payments because you are not able to perform your pre-injury employment.

If you have a WorkCover claim for medical expenses only, you do not need a certificate of capacity in Victoria.

Here’s an example of a completed certificate of capacity.

When is a certificate of capacity required?

To be clear, a regular medical certificate will usually look something like this (below):

When it comes to WorkCover claims, if you want to claim weekly payments you must have certificates of capacity.

You will not be paid weekly payments unless you have provided certificates of capacity (in some instances, insurers will accept statutory declarations).

A WorkCover insurer will not accept regular medical certificates.

A certificate of capacity is a specific medical certificate that is used in WorkCover matters.

The certificate of capacity not only includes the diagnosis of injury, but also includes a comment by the treating medical practitioner about your work capacity.

Each certificate of capacity will indicate whether a worker has a capacity for full unrestricted duties, modified duties, or no work capacity at all.

Here’s the section on the certificate where the person certifying you needs to indicate what your work capacity is:

A normal medical certificate on the other hand is the type of certificate that you might get from your doctor if you need time off work for a flu or for any other (usually) non-related work condition.
