Gap Cover for Out of Pocket Medical Expenses

Megan Fraser Fact Checked Updated: 07 August 2020
Types of Health Insurance

If you need to see a specialist in the private health sector, for example, a reconstruction surgeon, ENT specialist or urologist, get ready to pay some steep out of pocket expenses. A gap can arise when your hospital accommodation or specialist fees exceed the MBS payment.

When a specialist charges more than the MBS fee, you are responsible for paying the gap. However, private Hospital insurance might help you reduce these out-of-pocket medical expenses. The gap between the MBS rebate, your hospital expenses and your doctor’s fees, could be fully or partially covered by your Hospital policy, depending on your level of cover.

What are out-of-pocket expenses in health care?

Out-of-pocket expenses also called the ‘gap’, is the amount of money you must pay for health services and treatments that exceed what Medicare and your health fund will cover. Out-of-pocket expenses are generally influenced by the type of service you require, the availability of bulk billing, the specialist fees and the state you live in.

While the Australian government does subsidise specialist services through the Medicare Benefits Schedule (MBS), it rarely covers the full cost of your medical requirements. Out-of-pocket expenses that you might need to prepare for when going to the hospital include:

Out-of-hospital services

The Medicare rebate for out-of-hospital treatments is 85% of the schedule fee; you are thus responsible for paying the difference.

With nearly two-thirds of specialists not participating in bulk billing for out-of-hospital services and Medicare only covering 85%, thousands of Australians must pay for these from their own pocket.

In-hospital treatments

For private patients receiving treatments inside the hospital, the Medicare Benefits Schedule rebate is typically 75%. You and your health fund are thus responsible for paying the remaining 25%

What does no-gap mean in health insurance?

Gap cover, also called no-gap, is when you don’t have to pay any out-of-pocket expenses. Many private health insurance companies provide medical gap cover insurance on their Hospital policies. However, the gap amount may vary between providers.

Various private health insurance companies offer ‘no-gap’ and ‘known-gap’ services to help you reduce any potential specialist fees that exceed what Medicare will cover.

Gaps for doctor’s fees

When the doctor, specialist, surgeon or anaesthetist that’s involved in your hospital care charges more than the MBS fee, you incur out-of-pocket expenses. However, if your health fund has gap cover arrangements with your doctor, you might not have to contribute toward your doctor’s bill.


The maximum out-of-pocket costs your health fund will cover for hospital accommodation and doctor’s fees charged above the MBS fee. When you know what out-of-pocket expenses to expect, you can more easily budget for any future medical costs.

Important: Before you receive hospital treatment, contact your health insurer to find out if your doctor participates in the fund’s gap cover arrangements. Because doctors might charge on a case-by-case basis, you should also ask you doctors how much you’ll have to pay over and above your insurance coverage. You can find a list of gap doctors on

How does Access Gap Cover work?

Private Hospital plans that include Access Gap Cover helps reduce the cost of in-hospital services and treatments that exceed the 75% that Medicare pays. However, while many health funds provide medical gap cover insurance, it’s still the doctor’s choice whether they want to participate or not.

An example of a gap payment and gap cover

If your surgeon charges $1500 for treatment inside a private hospital, and the MBS fee cover is $750, your health fund will typically pay $250. You are then left with a $500 gap. This gap might be covered by your health insurance provider’s Access Gap Cover if the surgeon participates in the fund’s gap cover scheme.

Before undergoing a procedure, you must ask your doctor:

Also, inquire if the hospital where your treatment is planned for has an agreement with your health fund.

Gap cover generally does not apply to:

5 Ways to reduce your out of pocket expenses

  1. Get private health insurance with Access Gap Cover and request that your fund send you a list of healthcare professionals and hospitals that participate in their gap scheme. When being treated by a doctor or specialist that’s on the list, you should have no gap fees payable.
  2. Inquire from your medical specialist what their fees will be and how much of the costs will be covered by your private health insurance policy.
  3. Discuss alternative options with your specialists if out-of-pocket expenses exceed what you’re able to afford.
  4. Try to avoid treatment from specialists charging above the MBS fee. Compare costs from other doctors before booking your first consultation.
  5. Review your policy annually, generally after the 1st of April, as it can change over time, including its gap cover scheme.
