Direct billing or reimbursement: why your GP visit cost you money

You can leave a GP clinic having handed over cash even though your insurer paid the clinic directly. That is not necessarily a billing error, though an error cannot be ruled out until you have seen an itemised bill or your insurer’s benefit statement. Two different numbers are involved — the benefit your insurer allows, and the amount the clinic actually charges — and a third question sits on top: who pays first.

This article explains how the money moves, which arrangement you are in, and what to check afterwards.

The three numbers

• The MBS fee. The Medicare Benefits Schedule Online lists a reference fee for each service. It is a schedule price, not the price a clinic must charge.
• Your insurer’s benefit. The amount your policy pays for that service, calculated against the MBS fee. It depends on whether the service is covered and on your policy conditions, so it is not the same figure for every service you might have.
• The clinic’s charge. Whatever the clinic bills you, which may be below, at, or above the MBS fee.

Your out-of-pocket cost is the difference between the clinic’s charge and what your insurer actually pays.

85% of MBS is a floor, not your actual benefit

Schedule 1 of the OSHC Deed commencing 1 July 2025 sets the base out-of-hospital medical rate at 85% of the MBS fee, with higher benefits possible, and the in-hospital medical rate at 100% of the MBS fee.

Read that as a floor and a framework, not as your invoice. Two consequences matter:

• Your insurer may pay more than the base rate for a general practitioner consultation, depending on your product.
• A percentage of the MBS fee is not the same percentage of what the clinic actually billed you.

Insurance products differ. For example, the Allianz Care Australia Standard policy wording effective 1 July 2026 sets out most GP medical services outside hospital at 100% of the MBS fee, other out-of-hospital medical services including specialists, pathology and radiology at 85% of the MBS fee, and medical services to admitted hospital patients at 100% of the MBS fee. Read your own policy wording for the rates that apply to you — Allianz Care keeps current and archived documents separately. Not every OSHC policy works this way.

Three payment arrangements

Arrangement	Who pays upfront	What you still pay
Direct billing — the clinic bills your insurer, and your insurer pays the clinic	You may pay any gap at the visit; the insurer settles the covered amount with the clinic	Any gap between the clinic’s charge and the benefit, which the insurer’s direct billing explanation notes can still exist
Pay and claim (reimbursement)	You, in full	The same final gap, but you carry the cash flow and then claim it back under your insurer’s instructions
Medicare bulk billing	Medicare, where the practitioner bulk bills	Nothing for the bulk-billed service

Direct billing and pay-and-claim are two routes to the same benefit when the same service, charge and approved benefit are held constant — only the payment timing changes. In practice the clinic’s charge can differ, and some providers offer gap-free arrangements for direct billing, so check the specifics rather than assuming the two routes always produce the same final cost.

Bulk billing is different in kind. Under Services Australia’s explanation of bulk billing, a practitioner who bulk bills accepts the Medicare benefit as full payment for that particular service. It requires Medicare enrolment and the practitioner’s choice, and other services in the same visit may not be bulk billed. Holding OSHC does not make you a Medicare-eligible patient.

A simple worked example

These numbers are teaching cases, not MBS item fees or prices.

Case A — a gap remains. A clinic charges $100. Your confirmed benefit is $85. Direct billing: the insurer pays $85 and you pay $15. Reimbursement: you pay $100 at reception, your insurer reimburses $85 after processing, and your final cost is $15.

Case B — no gap. The clinic charges $100 and your insurer’s confirmed benefit is $100. Direct billing means nothing is collected from you. Reimbursement means you pay $100, then receive $100 back once the claim is approved.

Case C — the clinic charges above your benefit. The clinic charges $120 and your insurer’s confirmed benefit is $100. Direct billing: insurer $100, you $20. Reimbursement: you pay $120, receive $100, and your final cost is $20.

Within each case, the final gap is the same whichever route you take: $15 in Case A, $0 in Case B and $20 in Case C. Only the timing and who fronts the money change.

What to do before the visit

1. Ask the clinic whether they direct-bill your exact insurer and product.
2. Ask whether any gap would apply on top of that.
3. Ask whether they direct-bill your exact insurer and product, and if not, whether they bulk bill. Bulk billing is a Medicare benefit accepted as full payment for that service, and it requires Medicare enrolment — if you are not Medicare-eligible, it does not apply to you.
4. Have your membership card, physical or digital, ready at reception.
5. Check whether any waiting period applies to the service you are having. A waiting period means the benefit is not payable, which is a different problem from a gap.

What to do if you were charged something unexpected

1. Ask the clinic for an itemised invoice showing the provider, the service date, the service description and the amount charged, with the MBS item where applicable.
2. Keep your proof of payment.
3. Ask your insurer what benefit they calculated and why, using the claim instructions for your policy.
4. Check the deadline that applies to your policy before lodging.
5. If the numbers still do not line up, raise it with your insurer’s complaint process, giving them the itemised invoice and your benefit explanation.

Key takeaways

• Your out-of-pocket cost is the gap between the clinic’s charge and the benefit your insurer actually pays.
• The 85% of MBS out-of-hospital figure in the Deed is a base rate with higher benefits possible. It is not a prediction of any single GP benefit.
• Direct billing, pay-and-claim and Medicare bulk billing are three different things. Bulk billing depends on Medicare enrolment and a practitioner choosing it, and OSHC membership does not create Medicare eligibility.
• Direct billing changes who pays first, not what you finally pay. Check whether a gap applies even when the clinic bills your insurer and your insurer pays the clinic.
• If a charge looks wrong, get the itemised invoice and your insurer’s benefit explanation before concluding anything.
