If you’ve had a mastectomy, breast reconstruction is often considered a medically necessary procedure rather than an elective cosmetic one. In Australia, that distinction matters a lot for your wallet. Medicare covers 100% of the cost in a public hospital for the mastectomy itself, but reconstruction is a different story — and the gap between what you’re covered for and what you actually pay can run into thousands of dollars. More than 70% of private patients end up paying a gap fee, even with hospital cover.

Breast reconstruction after cancer treatment is treated differently by insurers than reconstruction for congenital conditions or trauma. The type of procedure — whether it’s implant-based or uses your own tissue (like a DIEP flap) — also changes what’s covered and what you’ll owe. And if you’re considering symmetry surgery on the other breast, that’s a separate question entirely. Here’s what you actually need to know.
What This Guide Covers and What to Watch For
Before we go further, let’s pin down one term you’ll see everywhere. A gap payment is the difference between what your surgeon charges and the combined total of your Medicare rebate and private health insurance benefit. It’s the most common out-of-pocket cost in private hospital surgery.
What I tend to notice is that people assume “medically necessary” means “fully covered.” It doesn’t. The gap is where most of the financial surprise lives.
Coverage Tiers, Waiting Periods, and What They Cost You
Your private health insurance policy tier is the single biggest factor in what you’ll pay. Medically necessary breast surgery — the mastectomy itself — is usually covered even on Bronze hospital policies. But reconstruction is a different category. Most insurers require at least Silver cover for reconstructive procedures.
Waiting periods are another hidden cost. For pre-existing conditions — and breast cancer is one — the standard waiting period is 12 months before you can claim benefits. That means if you take out a new policy or upgrade your cover after a diagnosis, you may not be able to claim for reconstruction until a full year has passed. The approval process itself takes 6 to 12 weeks from application to surgery authorisation, so factor that into your timeline.
Here’s how the main coverage tiers stack up for breast reconstruction:

| Policy Tier | Mastectomy Cover | Reconstruction Cover | Typical Gap Risk |
|---|---|---|---|
| Bronze | Usually covered | Often excluded | High — you pay full reconstruction cost |
| Silver | Covered | Often included | Moderate — gap likely but capped |
| Gold | Covered | Included | Lower — but still possible |
Even on Gold cover, the gap isn’t eliminated. The surgeon’s fee can be set well above the MBS schedule fee, and neither Medicare nor your insurer will cover that difference. For a standard mastectomy, the typical gap runs around $550. For a double mastectomy, it’s between $550 and $1,500. Reconstruction adds its own gap on top of that.
Where People Get Tripped Up
Mistaking “medically necessary” for “fully covered”
Medicare covers 75% of the MBS fee for in-hospital procedures. That’s not 75% of the surgeon’s bill — it’s 75% of a government-set fee that’s often lower than what surgeons actually charge. The remaining 25% of the MBS fee plus the entire amount above it lands on you. If your surgeon charges $5,000 and the MBS fee is $2,000, Medicare pays $1,500. Your insurer might cover some of the rest, but the gap can still be substantial.
Assuming Bronze cover is enough
Bronze policies often list “medically necessary breast surgery” as a covered service. That’s the mastectomy. Reconstruction is a separate procedure with its own MBS item numbers, and many Bronze policies explicitly exclude it. If you’re planning reconstruction, check your policy’s list of included procedures — not just the category name.
Ignoring the 12-month waiting period
If you’re diagnosed with breast cancer and then take out or upgrade private health insurance, the 12-month waiting period for pre-existing conditions applies. That means you can’t claim for reconstruction until a year after you joined or upgraded. Public hospital reconstruction is an option, but waitlists can be long. The timing of your insurance decisions matters as much as the coverage itself.
Overlooking symmetry and revision procedures
Reconstruction on the affected breast is one thing. Surgery on the other breast to make them match — a symmetry procedure — is often treated differently. If it’s considered functional (e.g., to correct imbalance that causes back pain), it’s more likely to be covered. If it’s seen as aesthetic, it may not be. Revision surgeries after reconstruction face the same split: functional revisions are more likely covered; purely aesthetic touch-ups are not.
How to Navigate Your Coverage Step by Step
Check your policy tier and exclusions
Start with your policy document, not a phone call. Look for the section on “plastic and reconstructive surgery” or “hospital cover exclusions.” If your policy is Bronze, assume reconstruction isn’t covered unless you see it listed by name. If it’s Silver or Gold, check whether there’s a sub-limit or co-payment for reconstructive procedures. Some policies cap the benefit at a dollar amount rather than covering the full MBS fee.
Get a written quote from your surgeon
Before you book surgery, ask your surgeon for a written fee estimate that includes the MBS item numbers for every procedure planned — mastectomy, reconstruction, any lymph node work, and any symmetry surgery on the other breast. Take that quote to your insurer and ask for a written benefit estimate. That’s the only way to know your likely gap before you commit.
Understand the Medicare Safety Net
If you’ve already spent a lot on out-of-pocket medical costs in a calendar year, the Medicare Safety Net can kick in and increase your rebate. For 2024, the threshold is around $2,500 for most people. Once you hit it, Medicare covers 80% of the gap between the MBS fee and what you’ve paid, rather than the standard 75%. If your reconstruction is later in the year and you’ve already met the threshold, your out-of-pocket costs could drop significantly.
Consider public hospital options
If private insurance isn’t an option — because of waiting periods, policy exclusions, or cost — public hospital reconstruction is available. Medicare covers 100% of the cost in a public hospital. The trade-off is that you don’t choose your surgeon, and waitlists for reconstruction can be long. Some public hospitals prioritise reconstruction for cancer patients, but it’s worth asking your treating team about expected wait times in your area.
Plan for future rule changes
The Australian government reviews the MBS regularly, and item numbers for reconstructive procedures can change. Private health insurance reforms also shift what’s required in each policy tier. If your reconstruction is more than six months away, check whether any MBS changes or insurance rule updates affect your coverage. Your surgeon’s billing team or a health insurance specialist can help you stay current.

The One Thing That Changes Everything
The difference between a $550 gap and a $5,000 gap often comes down to one thing: whether you checked your policy tier and your surgeon’s fee before you booked. More than 70% of private patients pay a gap, but the size of that gap is something you can influence. Get the written quote. Ask for the benefit estimate. Know your waiting periods. The system doesn’t make it easy, but the information is there if you push for it.
