Bulk-billed MRI: how a specialist referral can reduce or remove the out-of-pocket cost
By Dr Kimberley Wells, MBBS FACSEP · 12 May 2026 · 4 min read
A significant number of patients who see me have already paid several hundred dollars for an MRI that, with a specialist referral, may have been bulk-billed. The gap between what a GP can refer for and what a specialist can refer for is genuinely meaningful in imaging, and it is worth understanding before you book anything.
How bulk-billing works for MRI
Medicare has specific item numbers for MRI scans. When a scan is referred under an eligible item number, Medicare pays the radiology provider a scheduled fee. Most private radiology providers who participate in bulk-billing for these item numbers then charge no gap, meaning the patient pays nothing out of pocket for the scan itself.
The key word is "eligible." Not every MRI referral qualifies for a Medicare item number. And even among those that do, the item numbers accessible to GPs and those accessible to specialists are different, with different conditions attached.
GP referral versus specialist referral
For most musculoskeletal conditions, a GP does not have access to the Medicare item numbers that attract bulk-billed MRI at participating providers. This is not a criticism of GPs: it reflects the way the MBS is structured. GPs can refer for MRI, but for most joint and soft tissue conditions the referral falls under a non-rebatable item, and the patient pays the full private fee, which is commonly $300 to $500 or more depending on the body part and provider.
A specialist Sport and Exercise Medicine Physician (FACSEP) has access to a different set of MBS item numbers for musculoskeletal MRI. When these are used, most participating radiology providers bulk-bill, so there is usually no out-of-pocket cost for the scan. Bulk-billing is ultimately at the radiology provider's discretion.
This is one of the concrete financial benefits of seeing a specialist rather than going directly to imaging with a GP referral.
Which scans qualify
The specialist MBS item numbers for musculoskeletal MRI cover the major joints and regions: knee, shoulder, hip, ankle, foot, wrist, elbow, and spine, among others. The specific item used depends on the clinical indication and the body part being imaged.
Not every scan in every situation will qualify, and Medicare rules do apply. Part of the clinical assessment is determining whether imaging is indicated, what type is most useful, and whether the clinical picture meets the Medicare criteria. Where it does, the referral is written under the appropriate item. Where it does not, I will explain why and what the alternatives are.

What to do
If you have an injury or joint problem and are considering getting an MRI, it is worth seeing a specialist before booking the scan privately. The assessment will clarify whether imaging is actually needed, what type is most useful, and whether the referral can be written under a Medicare item number that attracts bulk-billing.
In many cases, the cost of the specialist consultation is less than the out-of-pocket cost of a privately paid MRI. And the scan comes with a clinical interpretation rather than a radiology report you are left to decode alone.
If you already have imaging and want it reviewed, bring it to the appointment. Imaging review is part of what a Sport and Exercise Medicine consultation covers. See the imaging page for more on how we use imaging in assessment.
