Some Pharmaceutical Benefits Scheme (PBS) subsidised medicines need written authority approval from us before they can be prescribed.
Some PBS medicines need written authority approval due to their clinical use or other special features.
This includes a number of Complex Authority Required (CAR) drugs.
These medicines won’t be PBS subsidised without authority approval, and we can’t grant retrospective approval.
Applying for authority approval
Health Professional Online Services (HPOS)
To apply for approval to prescribe a written authority required drug through HPOS, you must upload the completed and signed PBS authority application form, supporting documents and authority prescription form(s).
When approved, you can access the authority approval number through HPOS - you must record it on the authority prescription form. You should also record the item code on the authority prescription form.
To apply for approval to prescribe a written authority required drug through the mail, you must post the completed and signed PBS authority application form, supporting documents and authority prescription form(s) to us.
When approved, we stamp the authority prescription form with CAR approval and return it by mail to you or your patient as shown on the form.
Where you can make authority applications for balance of supply or continuing treatment by phone, you must call the PBS Complex Drugs Programs enquiry line.
When approved, you must record the authority approval number we provide on the authority prescription form. Phone authority approval numbers start with Z, CARZ or TRZZ and are followed by 4 digits and 2 letters. For example, Z1234AB or CARZ1234AB or TRZZ1234AB.
Hospital authority form
To prescribe CAR Highly Specialised Drugs (HSDs) in a:
- non-reform public hospital approved to supply HSDs, prescribers must use the Non PBS Reform Public Hospital Highly Specialised Drugs and Trastuzumab Only Authority Prescription Form (PB054)
- public hospital participating in the pharmaceutical reforms, the prescriber can use the Public Hospital Prescription form
- private hospital, prescribers can use their own personalised PBS prescription pads
