Post-Pregnancy Surgery and Medicare in Australia: Items 30175 & 45523 Explained

[IMAGE: Informational graphic showing the Medicare eligibility pathway for post-pregnancy procedures]

If you're considering post-pregnancy surgery in Australia, there's a decent chance part of your procedure could attract a Medicare rebate. The two most relevant MBS item numbers are 30175 (abdominoplasty for diastasis recti) and 45523 (breast reduction for macromastia). But the eligibility criteria are specific, the rebates are partial, and the process isn't always straightforward.

This guide explains both items in plain English — what qualifies, what doesn't, how much you'll actually get back, and how to work through the process.

Medicare Item 30175: Post-Pregnancy Abdominoplasty Explained

MBS Item 30175 was introduced on 1 July 2022 specifically for post-pregnancy abdominoplasty. Before this, there was no dedicated Medicare item for the procedure — women either didn't qualify for any rebate or had to rely on less specific item numbers.

To qualify, ALL of the following must be met:

1. Diastasis recti of 3cm or greater — This is the separation of the rectus abdominis muscles (the "six-pack" muscles) along the midline. It must be confirmed by imaging — typically an ultrasound or CT scan. Your GP can order this.

2. At least 12 months since your last pregnancy — You can't apply within the first year after delivery. This ensures your body has had time to recover naturally.

3. At least 6 months of conservative treatment — You need documented evidence that you've tried non-surgical approaches (usually physiotherapy for diastasis recti) and they haven't adequately resolved the issue. Keep records of your physio sessions — they form part of your Medicare claim.

4. Documented moderate-to-severe pain during functional activities — Your GP and surgeon need to document that the diastasis is causing pain during everyday activities like lifting, bending, or carrying your child. General dissatisfaction with appearance alone does not qualify.

What does "3cm or greater" mean practically? Your GP or physiotherapist can measure the gap manually during an examination. For the formal Medicare claim, imaging confirmation (ultrasound showing the measurement) provides the strongest evidence. Some surgeons will order this at your first consultation if your GP hasn't already.

The rebate amount: The MBS schedule fee for Item 30175 is approximately $1,042. Medicare pays 75% of the schedule fee for in-hospital procedures — so you'll receive roughly $781 back. Your surgeon's actual fee will be significantly higher (typically $6,000–$14,000 for the surgeon's fee alone, based on Pirk surgeon assessment data). The Medicare rebate helps, but it covers a small fraction.

Private health insurance: If you have hospital cover that includes the relevant category, your fund may cover the hospital component (bed, theatre, nursing) for a procedure billed under Item 30175. This can save you $3,000–$7,000 on top of the Medicare rebate. Call your fund with the item number and hospital details to get a specific answer.

Medicare Item 45523: Breast Reduction

MBS Item 45523 covers reduction mammoplasty (breast reduction) when performed for macromastia — excessively large breasts causing physical symptoms.

To qualify:

1. Documented macromastia — Your breasts must be disproportionately large relative to your body frame, as assessed by your surgeon.

2. Physical symptoms — Documented neck pain, shoulder pain, back pain, shoulder grooving from bra straps, skin rashes or infections in the breast fold (intertrigo), or nerve symptoms. Your GP's documentation of these symptoms over time strengthens the claim.

3. Performed by a specialist surgeon — The procedure must be performed by a surgeon registered with AHPRA who is qualified to apply the item number.

The rebate: Similar mechanics to Item 30175 — Medicare pays 75% of the schedule fee, which typically works out to $700–$1,200. Your surgeon's fee will be higher, and the gap is yours.

After pregnancy specifically: Breast changes during and after pregnancy and breastfeeding can result in macromastia that wasn't present before. If your breasts have increased significantly and are causing documented symptoms, you may qualify even if you didn't qualify pre-pregnancy.

What About a Breast Lift (Mastopexy)?

A breast lift performed purely for cosmetic reasons — to raise and reshape breasts that have dropped after breastfeeding — does not attract a Medicare rebate.

The exception: if a lift is performed as part of a breast reduction that meets Item 45523 criteria. In that case, the reduction component attracts the rebate; the lift element is considered part of the same procedure.

A standalone breast lift for post-pregnancy ptosis (sagging) is classified as cosmetic. Plan to pay the full cost yourself.

When Both Components Qualify: Combined Billing

Here's where it gets interesting for combined post-pregnancy procedures. If you're having abdominoplasty AND breast reduction in a single session, and both meet their respective Medicare criteria:

• Your surgeon can bill Item 30175 for the abdominoplasty component
• Your surgeon can bill Item 45523 for the breast reduction component
• Medicare applies a "multiple procedure rule" — the highest-value item is paid at full schedule fee, and subsequent items are paid at a reduced rate

In practical terms: You might receive $781 + $500–$800 (reduced rate for the second item) = approximately $1,300–$1,580 total from Medicare. Your private health insurance may cover the hospital stay under either or both item numbers.

The components that won't attract rebates: If you're also having a breast augmentation, liposuction, or any purely cosmetic element, those components are billed separately and don't attract any Medicare contribution. Your surgeon handles the split billing.

The Step-by-Step Process

Here's how to work through Medicare eligibility for post-pregnancy surgery:

Step 1: GP appointment See your GP. Discuss your symptoms — pain, functional limitations, discomfort. Ask them to document everything. If you suspect diastasis recti, ask for an ultrasound referral to measure the gap. If your breasts are causing pain, ask them to note the symptoms in your records.

Get a referral to a specialist plastic surgeon.

Step 2: Start conservative treatment (if you haven't already) For Item 30175, you need at least 6 months of documented conservative treatment (physiotherapy). Start this now if you haven't. Keep all receipts and records — your physio should document the diastasis measurement, your exercise program, and your progress (or lack thereof).

Step 3: Surgeon consultation Your surgeon will examine you, review your imaging and GP notes, and determine whether you meet Medicare criteria. They'll tell you which item numbers apply to your situation. Consultation fee: typically $200–$400, with a Medicare rebate of approximately $85 with a GP referral (per Services Australia).

Step 4: Get an itemised quote Ask for a quote that separates each component and lists applicable MBS item numbers. This is the document you'll use to check with your health fund.

Step 5: Call your health fund Give them the MBS item numbers, the hospital name, and the date of surgery. They'll confirm what they'll cover (hospital, theatre, bed) and what your gap will be. Get this in writing.

Step 6: Calculate your real out-of-pocket Total quote − Medicare rebate − health fund contribution = what you actually pay. This is the number that matters for your financial planning.

Common Misconceptions

"My GP says I have diastasis recti, so I definitely qualify for Medicare." Not necessarily. The GP's assessment is the starting point, but you need imaging confirming the gap is 3cm or greater AND documentation of 6+ months of failed conservative treatment AND moderate-to-severe pain during functional activities. All four criteria must be met.

"Medicare will cover most of the cost." The rebate is approximately $781 for Item 30175. Your total abdominoplasty cost will likely be $12,000–$25,000. Medicare covers roughly 3–6% of the total. It helps — but don't plan your budget around it covering a significant portion.

"If my surgery is partially covered by Medicare, it's not cosmetic." It's both. The diastasis repair component is functional (and attracts the rebate). But the skin removal, contouring, and any breast work done for appearance are cosmetic. Your surgeon bills each component appropriately.

"I can claim my breast lift on Medicare." A standalone breast lift for ptosis (sagging) after breastfeeding is cosmetic and does not attract a rebate. Only a breast reduction meeting Item 45523 criteria qualifies.

"Private health insurance covers everything Medicare doesn't." Your health fund typically covers the hospital component (bed, theatre, nursing) for procedures with valid MBS item numbers. It doesn't cover the surgeon's gap fee, anaesthetist gap, or any cosmetic components. You'll still have significant out-of-pocket costs.

What If You Don't Qualify?

If your diastasis is under 3cm, or your breast size doesn't meet reduction criteria, or you haven't completed the conservative treatment period — your procedures are classified as cosmetic, and Medicare won't contribute.

Frequently Asked Questions

Can I claim Medicare if I had my baby more than 5 years ago? Yes. There's a minimum waiting period (12 months after last pregnancy for Item 30175) but no maximum. If you still meet the clinical criteria years later, you can still apply.

Does Medicare cover liposuction as part of the procedure? No. Liposuction is classified as cosmetic and doesn't attract a Medicare rebate, even when performed alongside a Medicare-eligible abdominoplasty.

Can my surgeon help with the Medicare paperwork? Most experienced surgeons' rooms handle Medicare billing as a matter of course. They'll apply the correct item numbers, submit the claim, and advise you on what you'll receive. Ask at your consultation.

What if my health fund rejects the claim? Ask for the reason in writing. Check whether the item number was applied correctly. Your surgeon's rooms may be able to provide additional documentation. You can escalate to the Private Health Insurance Ombudsman if needed.
