Frequently Asked Questions
If your question isn't answered below, please submit it in 'Contact Us' and we will provide an answer promptly.
Do I need a referral to see a Doctor?
Yes. All specialist consultations require a valid referral (addressed to the specialist you are booked with).
All new patients will need to provide a referral at their initial consultation. Returning patients will need to renew their referral after:
- 12 months if it is from a GP, and
- 3 months if it is from another specialist
We will provide you with timely reminders when a new referral is due.
What will I need to bring to my appointment?
In addition to your referral and medicare card, please do your best to bring copies of any relevant scans, tests or procedure reports. The more information/history you can present to your specialist, the more thorough an investigation they can conduct.
Do you claim for Medicare or Private Health Funds?
Yes. Provided you bring your medicare card to the appointment, we process Medicare claims on the spot. The rebate, if successful, is transferred back into your nominated bank account within a day or two. Your medicare card is only necessary for your initial consultation.
If your child is seeing a Pediatrician, they will need a parent's medicare details and date of birth for the claim to be allocated to.
Please note, private health insurance cannot be claimed for any consultation.
What are the fees involved?
Specialist fees vary according to the type, length, and complexity of the consultation. If you would like an estimate for your appointment, please call our reception staff. As a private clinic, there is an upfront fee for each consultation (unless you are a hospital referred gestational diabetes patient).
What happens if I lose my pathology or imaging request form?
When you finish your consultation and present at the reception desk, we ask that you please produce all request forms that the doctor has given you so that we can scan copies onto your file. This way, we will be able to create another copy for you in the event that you lose the original. Should this happen, simply call our friendly receptionists and they will assist you.
