How to make an OSHC claim in Australia: the steps, the documents and the timing

An OSHC medical claim usually follows one of two common arrangements. Either your provider bills your insurer directly and you pay any gap the provider requires at the clinic, or you pay the bill yourself and claim it back. Which one applies depends on your provider and your policy conditions. This article explains both routes, the documents each one needs, and where the money actually goes.

Route one: the provider bills your insurer

Here is the flow when your provider offers it.

1. You attend the provider — a GP, specialist, pathology or imaging service.
2. You give your OSHC membership details so the provider can check your cover with the insurer.
3. The provider bills your OSHC insurer directly for the service. OSHC cover is not Medicare, so Medicare is not the payer here, even when the fee is calculated against the MBS.
4. The insurer pays the provider the benefit your policy allows.
5. You pay any gap the provider charges on top of that benefit, if they charge at all.

The gap is the part that surprises people. Your policy reimburses a percentage of a reference fee, not of whatever the provider actually charges.

The Allianz Care OSHC Standard policy wording effective 1 July 2026 is a good illustration of how these percentages work. It pays most GP medical services outside hospital at 100% of the MBS fee, and other out-of-hospital medical services such as specialists, pathology and radiology at 85% of the MBS fee.

Here is what that means in practice, using round teaching figures only. These are worked examples, not actual MBS item fees or quotations.

What the provider charges	Benefit your policy allows	What you are left to pay
$100	$85 (85% of a $100 reference fee)	$15
$100	$100 (100% of a $100 reference fee)	$0
$120	$100 (100% of a $100 reference fee)	$20

In that last row, if the provider direct-bills, the insurer pays the provider $100 and you pay $20. If you pay up front and claim, you hand over $120, receive the approved $100, and your final cost is still $20. Same service, same total, different order of operations.

Route two: you pay, then claim

Take this route when your provider does not direct-bill your exact insurer or product, when they ask for payment up front, or when your policy conditions mean you need to claim.

Ask the provider one question before you are seen: do you direct-bill my OSHC insurer and product, and is there a gap? That single answer determines which route you are on.

If the answer is no, keep these documents:

1. The itemised invoice showing each service, the date of service, the charge, your name, and the MBS item where the provider has applied one.
2. The receipt or proof of payment.
3. Your provider’s details — name, provider number and ABN where shown.
4. Your membership details — the policy or membership card number.
5. Any referral documentation your policy requires, where applicable.

Then submit the claim using your insurer’s stated instructions. Claim lodgement deadlines and processing times are set by the insurer, and they vary, so submit sooner rather than later and check with your insurer for the current cut-off.

The Medicare Benefits Schedule Online explains what an MBS item is. For medicines, the Pharmaceutical Benefits Scheme is the equivalent reference.

Hospital treatment is billed differently

Do not read the out-of-hospital percentages across to hospitals. Under the same Standard policy, medical services to admitted hospital patients attract 100% of the MBS fee, while hospital accommodation and facility costs sit in separate categories:

• Public hospitals — for the listed service categories, the benefit is set at the relevant State or Territory non-resident rate, not a percentage of the MBS.
• Agreement private hospitals — 100% of contracted charges for insurable costs, with accommodation at the shared ward level as a minimum.
• Non-agreement private hospitals — the applicable minimum benefit under the Benefit Requirement Rules.

The OSHC Deed commencing 1 July 2025 sets the framework beneath these policies. Its base out-of-hospital medical rate is 85% of the MBS fee, with higher benefits possible, and the in-hospital medical rate is 100% of the MBS fee. It is a floor, not a promise that your policy pays exactly those amounts on every service. Its public hospital provision is likewise limited to listed services at State or Territory non-Medicare rates — it is not free care covering every possible expense for every student.

Hospital treatment can also carry out-of-pocket costs beyond the benefit. See our article on why a “gap-free” policy can still leave you with a bill.

PBS prescriptions

Medicines work on a different structure again. Rather than guessing at pharmacy pricing, check what your own policy sets.

The useful thing to know is the shape of the limit. Where a prescription is an eligible item under your policy, the benefit is subject to a per-item limit and an annual limit, and any applicable patient contribution is not part of the benefit. None of these figures tells you what you will receive on a particular script: the amount actually paid depends on the item, the price charged and your policy conditions.

Habits that make claiming painless

1. Carry your membership card, and keep the digital version on your phone.
2. Ask the direct-billing question before the consultation, not after.
3. Keep every receipt, even on services billed directly.
4. Check your waiting period first. A service you receive during an applicable waiting period is generally not payable under that part of your cover — see OSHC waiting periods.
5. If the numbers do not agree, ask the provider for an itemised invoice and the insurer for a benefit explanation before assuming an error or refusing payment.

Frequently asked questions

Does my provider bill Medicare first and then my insurer? No. For an OSHC claim, your OSHC insurer is the payer. Medicare bulk billing means accepting the Medicare benefit as full payment for a service, and it requires Medicare enrolment and a practitioner who bulk bills — Services Australia explains the scheme. OSHC membership is a separate cover, so it does not make you Medicare eligible.

Is direct billing always free? No. Direct billing removes the reimbursement paperwork, not the gap. The gap is the provider’s charge minus the benefit your insurer approves, so a gap can remain even where the charge is at the MBS fee — for example, where your benefit is 85% of a $100 MBS fee, you would still pay $15. Some providers offer gap-free arrangements for certain services — Allianz Care explains how its direct billing works — but policy conditions apply.

Why is my benefit less than I expected? Several possible reasons may explain a smaller benefit: the benefit for the MBS item, items your policy excludes, or a limit or condition in your policy. Ask your insurer for a written explanation of how the benefit was calculated before you decide whether something is wrong.

Do I still need receipts if the provider direct-bills? Keeping them is prudent, but the main value is on the reimbursement route.

How long does a claim take? Processing times vary by insurer and claim. Confirm current timeframes and deadlines directly with your insurer rather than relying on a fixed figure.

Key takeaways

• Two common arrangements: the provider direct-bills your insurer, or you pay and claim.
• The insurer is the payer. Medicare sits outside an OSHC claim.
• A percentage of the reference fee is not a percentage of the invoice. That gap is yours.
• Hospital accommodation is not an MBS percentage. Public, agreement private and non-agreement private hospitals each work differently.
• Eligible prescription benefits have per-item and annual limits, and any applicable patient contribution sits outside the benefit. Neither limit is a guaranteed payout.
• Check the waiting period, then ask the direct-billing question.
