What to bring. What to expect.

Most first consultations run for 45 minutes. We’ll review your history, talk through eligibility, discuss the pathways that may suit you, and answer every question you bring.

✦  Private health insurance

Insurance & rebates, explained.

Bariatric surgery is covered by most Gold-tier Australian private health funds. Your fund typically covers hospital and theatre fees in full. You’re left with an out-of-pocket “gap” for the surgeon, anaesthetist, surgical assistant and our comprehensive 12-month post-operative care programme.

Uninsured patients can self-fund in a private hospital — significantly more, since you cover hospital and theatre yourself. We also work with AccessMySuper for patients exploring early release of superannuation.

Which item numbers should I check with my fund

The most commonly used MBS item numbers are 31572 (gastric sleeve), 31575 (gastric bypass) and 30511 (intragastric balloon insertion). Call your fund’s pre-admission line and ask about your coverage for each item.

Most funds require a 12-month waiting period after taking out hospital cover or upgrading to a Gold-tier policy before they will cover obesity surgery. If you’ve recently upgraded, we’ll help you work out when you’re eligible.

For an insured Gold-tier patient, the gap fee for a sleeve gastrectomy is typically $7,000–$9,000. The bypass is $9,000–$12,000. The intragastric balloon is around $7,000 in full (insurance varies). We provide an itemised quote at consultation.

Some patients access their superannuation early under compassionate grounds to fund the gap. We work with AccessMySuper, who specialise in this process. Approval typically takes 4–8 weeks.
