Acting for someone

You can act for someone to help them with their Medicare business.

When you act for someone it means you manage their Medicare business for them.

There must be a good reason why they can’t do this. For instance, they may not be able to make decisions because of illness or disability.

There are 3 situations in which you can act for someone:

  • you’re their appointed power of attorney
  • you’re their court appointed legal guardian or administrator
  • you need to act for them because they can’t manage their own Medicare business because of a medical condition.

If you’re acting for someone, you can:

  • ask us questions on their behalf
  • make decisions about Medicare for them
  • update their contact and bank details
  • make Medicare claims for them.

You can manage their Medicare business in person or over the phone.

To claim Medicare benefits on their behalf, submit a Medicare Claim form.
