X-Ray, CT Scan and MRI: OSHC Coverage Rules

A practical guide for international students in Australia — x-ray, ct scan and mri: oshc coverage rules.

If you’ve just been handed a referral for an X-ray, CT scan or MRI, the question isn’t just “is it covered?” — it’s “exactly how much will I pay and how do I make sure it’s zero or close to zero”. OSHC covers most diagnostic imaging at 100% of the Medicare Benefit Schedule (MBS) fee when you’re not admitted to hospital. The catch is that the clinic’s charge and your choice of provider determine whether you walk out with zero cost or a $300 gap. This is a step-by-step breakdown of how coverage works under Bupa, Medibank, Allianz Care, nib and AHM — so you can schedule the scan without guessing.

How OSHC Covers Radiology: The Basics

All five OSHC providers follow the same minimum standard set by the Department of Health. For outpatient radiology (a scan done outside a hospital admission, even if the clinic is attached to a hospital), the rule is straightforward:

• OSHC must pay 100% of the MBS fee for the imaging service.
• This applies to X-ray, CT, MRI, ultrasound and nuclear medicine scans, provided they are medically necessary and listed on the MBS.
• The cover is the same whether the referral comes from a GP or a specialist.

In practice, this means the insurer sends money to the radiology clinic (direct bill) or reimburses you up to the MBS fee if you pay first. Anything the clinic charges above that MBS fee — the “gap” — is your responsibility.

For scans performed during a private hospital stay, OSHC covers 100% of the MBS fee for the imaging itself, plus other hospital costs under your policy’s hospital cover. Gap risks here depend on whether the hospital and the radiologist participate in the insurer’s gap scheme. Allianz Care, Bupa, Medibank, nib and AHM all run some form of gap-cover arrangement for in-hospital medical services, but you must check that the provider is part of it before admission.

A note on accidents and emergencies: if you present to a public hospital emergency department and get an urgent X-ray or CT, your OSHC covers the entire episode as a public patient at no cost to you. The tips below focus on planned outpatient scans, where costs are easiest to control.

Step‑by‑Step: From Referral to Zero-Cost Scan

Treat this as your decision checklist. Start here each time you receive a referral.

1. Get a valid referral. Only a GP or specialist referral can trigger Medicare (and thus OSHC) benefits. Without one, the scan is considered an uninsured private service — OSHC pays nothing.
2. Confirm the scan is Medicare‑eligible. Your doctor should write a specific MBS item number on the request (e.g. 58503 for a chest X-ray). If they haven’t, call the radiology desk and ask them to check. MRI scans, in particular, have strict eligibility rules (see separate section).
3. Decide how you want to pay.
   • Direct bill (no money up front): the clinic sends the claim straight to your OSHC insurer and accepts the MBS rebate as full settlement. Result: $0 out of pocket.
   • Pay then claim: you pay the clinic’s full fee, then submit a claim to your insurer. The insurer refunds the MBS amount; you keep the difference (the gap).
4. Find a direct‑bill / bulk‑bill clinic. Use your insurer’s app or portal to search for “radiology” or “diagnostic imaging” providers that offer direct billing to international students. Then phone the clinic and confirm: “I’m an international student with [Allianz Care/Bupa/etc]. If I provide my membership details, can you bill my insurer directly so I have no out-of-pocket cost?”
5. Present your OSHC membership card or digital card at the appointment. The clinic lodges the claim electronically.
6. If you paid upfront: get an itemised receipt showing the MBS item number, provider number, date of service, amount paid and a copy of the referral. Submit everything through your insurer’s claims portal within 24 months.

Red flag: Some clinics tell you they “accept OSHC” but quietly add a gap. Always ask the two‑part question: “Do you direct‑bill my specific OSHC fund, and will I have any out‑of‑pocket expense?”

Bulk‑Billing vs. Pay‑and‑Claim: What You’ll Actually Pay

Below are real‑world examples based on MBS fees in 2026–27. These numbers reflect what your insurer will pay (if the service is eligible) and what you might keep if the clinic charges more.

• Chest X‑ray (MBS item 58503)
  MBS fee: ~$55
  Bulk‑bill clinic: $0
  Private clinic that charges $85: you pay $85 upfront, insurer refunds $55 — your gap is $30.

• CT scan of the brain, without contrast (MBS item 56007)
  MBS fee: ~$290
  Bulk‑bill clinic: $0
  Private clinic that charges $510: your gap is $220.

• MRI of the lumbar spine (MBS item 63551)
  MBS fee: ~$420 (when Medicare‑eligible)
  Bulk‑bill clinic: $0 (rare for MRI — see below)
  Private clinic eligible charge $595: your gap is $175.
  If the MRI is NOT Medicare‑eligible: OSHC pays $0 and you pay the full clinic fee — typically $500–$800.

• Panoramic dental X‑ray (OPG) — often needed for wisdom teeth removal
  MBS item 57969: ~$55
  Dental radiology practices frequently bulk‑bill this. No gap if direct‑bill.

All figures are approximate and index with the MBS each November. Always confirm the gap before the appointment — a 60‑second phone call can save you hundreds of dollars.

Finding a Radiology Clinic That Works with Your OSHC

Each insurer maintains a searchable provider directory. Here’s where to look and what to select.

Bupa OSHC

• Path: Log into myBupa → Find a Provider → Diagnostic Imaging.
• Filter: Tick “Bupa Recognised Provider” and “Bulk billing” or “Direct billing” where available.
• Field note: Many I‑MED Radiology and Lumus Imaging centres direct‑bill Bupa OSHC for X‑ray and CT. For MRI, ask the centre whether they bulk‑bill Bupa members — the answer varies by location.

Medibank OSHC

• Path: Medibank app → Make a claim → Medical → Find a provider (or use the “Members’ Choice” directory on the website).
• Filter: Look for “Diagnostic Imaging” and note clinics marked as “gap‑free” for in‑hospital, but for outpatient scans focus on “direct billing”. Medibank has a wide network called “Medibank Members’ Choice” — check the box.
• Claim tip: If you pay first, the Medibank app lets you photograph the receipt and referral in one flow.

Allianz Care OSHC

• Path: Allianz MyHealth portal → Make a claim → Find a Doctor / Provider → Medical services → Radiology.
• Clue: Allianz Care uses a “direct billing” network (Allianz Care Medical Providers). Over 1,000 radiology centres participate. In the MyHealth portal, switch to “Direct billing” view; the map will show you clinics that handle everything for you.

nib OSHC

• Path: nib app → Claims → Find a provider → nib Medical Solutions.
