024 Types of Weight Loss Surgery
  • Gastric sleeve
  • Gastric bypass
  • Lap-Band
  • Gastric balloon

weight loss surgery australia

The 3 most common types of bariatric surgery in Australia are (in no particular order):

  • Gastric bypass (also called Roux-en-Y or RNY gastric bypass)
  • Gastric sleeve (also called vertical sleeve gastrectomy or just “sleeve gastrectomy”)
  • Adjustable Gastric Band (commonly called Lap Band which is a specific brand made by Apollo, formerly Allergan. Other brands include the Swedish Band and Heliogast)

The gastric balloon is also gaining popularity as an "in between" option that is more aggressive than diet and exercise but less aggressive than traditional bariatric surgery.

The links above will take you to a page with everything you need to know about each procedure including average weight loss for each procedure, impact on obesity-related health problems, potential risks and complications, and what life is like after surgery.

Since obesity is considered a pre-existing condition, you will probably have to wait 12 months between joining a health fund and getting approved for surgery.

Note that many surgeons will not perform any surgery other than gastric banding (Lap Band) if you do not have private insurance.

To get the specific coverage information and your out of pocket costs from your health fund, contact them directly and provide the following Medicare item numbers:

  • Gastric banding – Item 31569
  • Gastric bypass – Item 31572
  • Gastric sleeve (sleeve gastrectomy) – Item 31575
  • Duodenal switch – Item 31581
  • Reversal of Gastric Banding/Lap Band (removal or replacement of gastric band) – Item 31584
  • Intragastric balloon – There is no item number specifically for the balloon, but you can provide the number for gastroscopy since they may pay for that portion of the treatment – Item 30473

Click here for a full list of Australian health funds and their contact information.

You can also contact your local qualified surgeon for help understanding total costs and how insurance will apply.

Medicare Reimbursement

weight loss surgery australia medicare

Medicare will provide some reimbursement for the procedures listed below, although the rebate amount will still leave the majority of costs up to you and your private insurance.

To determine your rebate amount, Medicare applies a set rate to each covered procedure (that is much lower than the actual surgery costs), then they give you a rebate of 75% of that set rate.

Click here to access the Medicare Benefits Schedule (MBS) database and type in the following Item Numbers for current reimbursement levels for each procedure:

  • Gastric banding – Medicare Benefits Schedule – Item 31569
  • Gastric bypass – Medicare Benefits Schedule – Item 31572
  • Gastric sleeve (sleeve gastrectomy) – Medicare Benefits Schedule – Item 31575
  • Duodenal switch – Medicare Benefits Schedule – Item 31581
  • Reversal of Gastric Banding/Lap Band (removal or replacement of gastric band) – Medicare Benefits Schedule – Item 31584

If you need help determining Medicare rebate amounts, talk with your local surgeon.

Accessing Superannuation Benefits for Weight Loss Surgery Australia

weight loss surgery australia superannuation

The Department of Human Services (DHS) will consider the early release of your superannuation funds on what they call "specified compassionate grounds" for a medical treatment that:

  1. Treats a life-threatening illness
  2. Alleviates acute or chronic pain

Obesity may fall under one or both of these categories. And since weight loss surgery is recognized as an effective medical treatment for obesity, the DHS may agree to an early release of your funds to help with your surgery payment.

Tax Offset for Weight Loss Surgery Australia

bariatric surgery australia tax offset

If your out of pocket expenses for bariatric surgery (and all other net medical expenses) are over the Australian Taxation Office (ATO) threshold, you can claim an offset on your tax return.

According to the ATO…

“To claim the net medical expenses tax offset in your tax return, you will need to know the total medical expenses you incurred for yourself and your dependants. You then deduct any refunds from Medicare, your health fund or any other reimbursements that relate to those expenses received during the financial year.”
