Someone to act for you

You can ask someone to act on your behalf for your Medicare business.

A person can act on your behalf for Medicare purposes when any of the following applies:

  • they’re your appointed Power of Attorney (POA)
  • a court or tribunal has appointed them as your guardian and administrator
  • we’ve accepted them as your authorised representative
  • they’re your authorised third party.

The POA or guardianship and administration order must show your representative can act on your behalf for financial matters.

Authorised third party

You can give us permission to release your compensation information to a third party. They can also complete and sign relevant documentation on your behalf. Use the Medicare Compensation Recovery Third party authority form.

An authorised third party also includes legal representatives.

A legal representative is a person who has been legally appointed by law to act on the injured person’s behalf.

You can appoint a legal representative with one of the following:

  • a Last Will and Testament confirming the executor or executrix of the estate
  • Letters of Administration or Probate where the injured person dies intestate, without a Last Will and Testament in place
  • Public Trustee documentation
  • a Court order.

Removing a Medicare representative

You can call us to remove a Medicare acting arrangement.
