Yes — you need a referral for an MRI. MRI is the scan where this matters most for cost: for some MRIs, a Medicare rebate only applies if a specialist refers you, while others are rebatable on a GP referral when criteria are met. Even when eligible, each clinic sets its own fee, so the gap (your out-of-pocket cost) varies — and some clinics bulk bill. Ask the clinic before you book.
Key takeaways
- You need a referral for an MRI.
- Some MRIs are only rebatable if a specialist refers you; others on a GP referral.
- Even when eligible, the gap varies between clinics.
- Some clinics bulk bill eligible MRIs — ask before you book.
Yes — you need a referral for an MRI. And of all the scans, MRI is the one where the details of the referral most affect what you pay.
You need a referral — and who refers can matter
An MRI must be requested by a doctor. For Medicare rebate purposes, MRI has a particular wrinkle: for some MRI scans, a rebate only applies if you’re referred by a specialist, while others are rebatable on a GP referral — provided Medicare’s clinical criteria are met.[1] Your referring doctor will know which applies to your situation.
This is why two people can have “an MRI” and face very different costs — it can depend on who referred them and why.
Why your out-of-pocket cost varies
Even when a scan is Medicare-eligible, Medicare pays a set rebate while each clinic sets its own fee. The difference between the fee and the rebate is the gap — your out-of-pocket cost — and it varies between clinics.[2]
Bulk billing means no gap
Some clinics bulk bill eligible MRIs, accepting the Medicare rebate as full payment, so there’s no gap to pay.[1] Whether a clinic bulk bills is its own decision, separate from Medicare eligibility — which is why availability differs from place to place.
The practical tip
Before booking, ask the clinic directly: “With this referral, is my MRI Medicare-eligible, will it be bulk billed, and if not, what’s my out-of-pocket cost?” For MRI especially, this is worth checking up front.
Frequently asked questions
Why do I need a specialist referral for some MRIs but not others?
Medicare’s rules make some MRI scans rebatable only on a specialist referral, while others qualify on a GP referral if criteria are met. Your doctor will know which applies — and it affects whether you get a rebate.[1]
Why is an MRI free at one clinic and not another?
Because bulk billing is each clinic’s own decision, and clinic fees differ. Where a scan is eligible and the clinic bulk bills, there’s no gap; elsewhere you may pay an out-of-pocket gap.[2]
