What to do if your Medicare provider number is exposed in a data breach

11 November 2022

We have measures in place to protect your details if you were affected by the Medibank Private and AHM data breach.

If you were notified that your Medicare provider number has been exposed, you don’t need to request a new provider number.

A Medicare provider number uniquely identifies you and the place you work. These are already publicly available numbers that are printed on health certificates, patient referrals and invoices.

A provider number is not enough information for a criminal to access Medicare records or claiming systems. These claiming systems include security measures to prevent unauthorised access.

What you need to do

As an additional measure of security, when you update your personal details, including bank account details, you’ll need to do this online through Health Professional Online Services (HPOS).

Next steps

If you suspect someone may be committing fraud against Medicare using your Medicare provider number, you should report it to us.
