Do you need a referral for an X-ray?
Quick answer

Yes — you need a referral from a doctor (or dentist) for an X-ray, and it's what makes you eligible for a Medicare rebate. Plain X-rays are relatively inexpensive and are often bulk billed, meaning no out-of-pocket cost. Where a clinic charges above the rebate, the difference (the gap) is yours to pay and varies by provider — so it's worth asking the clinic when you book.

 Key takeaways

  • You need a referral from a doctor for an X-ray.
  • A valid referral makes you eligible for a Medicare rebate.
  • X-rays are relatively inexpensive and often bulk billed.
  • Any gap varies by clinic — ask when you book.

Yes — you need a referral for an X-ray. The good news is that X-rays are usually the most affordable type of imaging, and often cost you nothing.

Why you need a referral

An X-ray must be requested by a doctor — usually your GP, sometimes a specialist or dentist. That referral confirms the scan is appropriate and makes you eligible for a Medicare rebate (when criteria are met).[1] Imaging referrals are generally valid for 12 months for the same problem.

Often bulk billed

Plain X-rays are relatively inexpensive, and many clinics bulk bill them — accepting the Medicare rebate as full payment, so there’s no out-of-pocket cost for you.[1] Whether a clinic bulk bills is its own decision, but for X-rays it’s common.

If there’s a gap

If a clinic charges more than the rebate, the difference is the gap — your out-of-pocket cost — and it varies by provider.[2] Because it varies, a quick question when booking — “Is this bulk billed, and if not, what will I pay?” — tells you exactly what to expect.

Frequently asked questions

Can I just walk in for an X-ray without a referral?

No — an X-ray needs a doctor’s referral, which also makes you eligible for a Medicare rebate. With the referral, many clinics bulk bill X-rays.[1]

Are X-rays usually free?

Often, yes — X-rays are inexpensive and frequently bulk billed, meaning no out-of-pocket cost. If a clinic charges a gap, it varies by provider, so it’s worth asking when you book.[2]
