Dr Scott J Turner | Specialist Plastic Surgeon (FRACS) | Sydney
Breast reduction surgery is one of the few breast procedures that may attract a Medicare rebate in Australia, but only when specific clinical criteria are met. Macromastia (significantly enlarged breasts), documented pain in the neck or shoulder region, and a defined body of evidence, including photographs, examination findings, and often imaging, must all be in place before Medicare Item 45523 applies. For patients who do qualify, the financial impact is substantial. The Medicare rebate itself is a partial amount, but qualifying for that item number is what unlocks private health fund cover of the hospital and anaesthetic fees, which is where the real cost saving sits.
Dr Scott J Turner is a Specialist Plastic Surgeon (FRACS) with Sydney clinics in Bondi Junction and Manly, where he performs breast reduction surgery for patients across Sydney’s Eastern Suburbs, Northern Beaches, and wider metropolitan area, including through the Medicare Item 45523 pathway where clinical eligibility is established.
Who This Guide Is For
This guide is written for patients in Sydney who are:
- Researching whether their breast reduction surgery might qualify for a Medicare rebate
- Trying to understand what clinical criteria need to be met for Item 45523
- Wanting to know what documentation and evidence is required
- Unsure whether their private health insurance will help, and under what conditions
- Looking at the full cost picture with and without Medicare rebate
If you’ve been told by a GP that you may be eligible for a rebate, or if you’re trying to assess your own situation before consultation, this guide covers the process in plain terms.
Medicare Breast Reduction — Quick Summary
- Item number. MBS Item 45523 — Reduction mammaplasty (bilateral) with surgical repositioning of the nipple
- Primary clinical criteria. Macromastia plus documented pain in the neck or shoulder region
- What it excludes. Cannot be combined with insertion of any breast prosthesis
- Rebate amount. Just over $1,000 AUD from Medicare
- Why it matters beyond the rebate. Qualifying for Item 45523 is what enables private health fund cover of hospital and anaesthetic costs, which typically reduces total out-of-pocket cost by $5,000 or more
- Documentation required. GP referral, specialist examination, clinical photographs, and in many cases measurement or imaging of breast volume
- Related items. 45520 (unilateral, breast cancer or developmental abnormality) and 45522 (unilateral, without nipple repositioning)
What Is MBS Item 45523?
Item 45523 is the Medicare Benefits Schedule code for bilateral breast reduction surgery with surgical repositioning of the nipple. The full MBS definition specifies two conditions that must be met:
- The patient has macromastia (clinically enlarged breasts)
- The patient experiences pain in the neck or shoulder region related to the breast size
There’s a third requirement embedded in the item: the procedure must not involve the insertion of any prosthesis. In other words, a patient can’t claim Item 45523 for a breast reduction performed at the same time as breast implants.
The rebate amount Medicare pays for Item 45523 is just over $1,000 AUD, which represents 75% of the MBS scheduled fee. Private surgeons charge private fees that are higher than the MBS scheduled fee, so Medicare covers only the portion aligned with the scheduled fee, with the remainder being a gap.
The direct rebate amount isn’t large. What makes Item 45523 financially significant is what it unlocks with private health insurance.
Why Item 45523 Matters Even When the Rebate Is Modest
The rebate itself is around $1,000. The real value of qualifying for Item 45523 is that private health funds only cover a procedure when it has a valid MBS item number AND the patient meets the Medicare eligibility criteria.
If your breast reduction qualifies for Item 45523, and you have appropriate private health insurance (usually a top-tier hospital cover), your private health fund will cover the hospital accommodation and anaesthetic fees. These are substantial costs in private surgery, often running into several thousand dollars. Without Medicare eligibility, you pay these costs yourself.
For patients with top-tier private health insurance who qualify for Item 45523, the combined savings from Medicare plus private health fund cover can reduce total out-of-pocket cost by $5,000 or more compared to paying for a purely cosmetic breast reduction. This is why understanding eligibility matters, even when the direct Medicare rebate figure looks relatively small.
Patients should always verify with their private health fund before booking surgery that their specific policy covers Item 45523, because some funds only provide cover at the highest policy tiers.
The Clinical Criteria for Item 45523
Qualifying for Item 45523 isn’t a matter of the surgeon’s discretion. The criteria are set by Medicare, and eligibility is determined by clinical evidence documented through your GP, specialist plastic surgeon, and supporting investigations.
The two core criteria are:
Macromastia. This is the clinical term for significantly enlarged breasts. There isn’t a single bra-size threshold that defines macromastia, because breast size is relative to body frame, chest wall width, and overall proportion. A DD cup on a petite frame can represent macromastia; a DD cup on a larger frame may not. Assessment takes into account breast weight, volume, chest wall measurements, and overall proportion. Some assessments include volumetric imaging or weight-based estimation of breast tissue.
Neck or shoulder pain. Pain documented to be related to the weight of the breasts. Typical patterns include chronic neck pain, upper back pain, shoulder pain, bra-strap grooving (indentation from bra straps under the weight of the breast), numbness or tingling in the hands from nerve compression, headaches, and postural issues. The pain must be documented in medical records over time, ideally with a history of conservative management (physiotherapy, bra fitting, weight management) that hasn’t resolved the symptoms.
The MBS is strict on this. Both criteria need to be met, not just one.
Documentation Requirements
Medicare audits are routine, and surgeons won’t bill Item 45523 unless the documentation supports it. The typical evidence required includes:
- GP referral. Documenting symptoms, duration, and history of conservative management
- Specialist examination. Detailed assessment of breast size, chest wall measurements, posture, and pain distribution
- Clinical photographs. Standardised views of the breasts, chest, back, and posture, usually taken at consultation
- Volumetric assessment. In many cases, measurement or imaging of breast volume to demonstrate the degree of macromastia
- Documentation of symptoms over time. Evidence that the pain is chronic and not a recent development
- Evidence of conservative treatment failure. Documentation that non-surgical approaches (physiotherapy, professional bra fitting, weight management if appropriate) have been tried without resolving the symptoms
Rules around documentation tightened substantially at the end of 2018, which is why some older blog posts on Medicare breast reduction may describe a less stringent process than what applies today.
The Process from GP to Surgery
The pathway from initial GP visit to surgery under Item 45523 typically follows these steps.
Step one. GP consultation to discuss symptoms. Document pain, duration, and history of conservative management. GP provides a specialist referral, which is required under AHPRA cosmetic surgery guidelines, regardless of Medicare eligibility.
Step two. First consultation with Dr Turner. Detailed assessment of breast size, chest wall measurements, pain distribution, and overall clinical picture. Discussion of whether the clinical picture is likely to meet Item 45523 criteria. Clinical photographs taken. Discussion of surgical options.
Step three. Between consultations. GP or allied health documentation of any conservative management not yet tried. Additional investigations if needed. Private health insurance verification with your fund to confirm Item 45523 is covered at your policy level.
Step four. Second consultation with Dr Turner (minimum two consultations required under AHPRA guidelines). Review of all documentation. Confirmation of eligibility or clarification of gaps. Finalisation of surgical plan. Psychological evaluation is conducted as part of the AHPRA requirements.
Step five. Cooling-off period. Mandatory under AHPRA guidelines before formal consent is given.
Step six. Surgery. Performed at an accredited Sydney private hospital. Standard bilateral reduction mammaplasty with nipple repositioning.
The process from first GP visit to surgery typically runs several months when Medicare eligibility is being pursued. Patients should factor that timeline into their planning.
Cost Context with and without Medicare
The cost of breast reduction surgery in Sydney varies significantly based on Medicare eligibility.
Breast reduction with Item 45523 and private health insurance. Patients who qualify and have top-tier private health cover typically have hospital, anaesthetic, and significant surgical fee components covered. Out-of-pocket cost varies based on surgeon gap fees, anaesthetist gap, and the specific policy, but total gap is usually significantly lower than the cosmetic-only pathway.
Breast reduction without Medicare eligibility (cosmetic). Paid entirely out of pocket. Costs include the surgical fee, hospital facility, anaesthetist fee, and post-operative care. A detailed quote is provided after consultation. The breast surgery cost guide covers non-Medicare pricing in more detail.
The surgical approach itself is the same in both cases. What differs is the funding source and the pre-surgical documentation process.
What Medicare Won’t Cover
Understanding what’s not covered is as important as understanding what is.
- Breast reduction combined with implants. If implants are inserted during the same procedure, Item 45523 cannot be claimed. This rules out combining cosmetic augmentation with reduction.
- Purely cosmetic breast reduction. Patients without documented neck or shoulder pain, or without macromastia, are not eligible regardless of preference.
- Revision for cosmetic-only reasons. If your original breast reduction was cosmetic, revision is usually also considered cosmetic.
- The full cost of surgery. Even when Item 45523 applies, Medicare covers only a portion (75% of the MBS scheduled fee). Private health insurance fills some of the remainder if you have appropriate cover. Gap fees still apply.
Medicare rebate eligibility is subject to review and can change. The criteria described here reflect the position as of 2026, but the MBS is updated periodically.
Related MBS Item Numbers
Item 45523 is the most common breast reduction item, but it isn’t the only one.
Item 45520 covers unilateral breast reduction (one breast only) with surgical repositioning of the nipple, in the context of breast cancer or developmental abnormality of the breast. This is used for reconstruction or correction of significant asymmetry with a documented clinical cause.
Item 45522 covers unilateral breast reduction without nipple repositioning. Used in specific reconstructive scenarios.
Which item applies to your specific case is determined at consultation by your surgeon, based on clinical presentation and documentation.
How Dr Turner Handles the Medicare Process
Dr Turner and his team assess Medicare eligibility as part of the standard consultation process for any patient who asks about breast reduction and has symptoms that may meet criteria. The assessment follows the clinical evidence, not patient preference, which means some patients who hope to qualify will be advised that their clinical picture doesn’t meet the criteria, while others who weren’t sure may find they do.
The practice coordinates the documentation required for Medicare billing, including clinical photographs, measurements, and examination notes. Private health insurance verification is the patient’s responsibility, but the practice provides the Item 45523 code information needed to confirm cover with the fund.
AHPRA Consultation Requirements
The AHPRA cosmetic surgery guidelines that came into force on 1 July 2023 apply to breast reduction surgery even when the procedure is performed under Medicare Item 45523. The requirements are separate from and additional to Medicare eligibility.
You’ll need a referral from your GP or specialist physician. A minimum of two consultations with Dr Turner before surgery is booked. A psychological evaluation is conducted to confirm suitability. A mandatory cooling-off period sits between consent and surgery.
These apply regardless of whether your procedure is Medicare-rebated or cosmetic.

Frequently Asked Questions
Does Medicare cover breast reduction surgery in Australia?
Medicare may cover breast reduction surgery through Item 45523, but only when specific clinical criteria are met. These include macromastia (clinically enlarged breasts) plus documented pain in the neck or shoulder region. The procedure cannot involve insertion of breast implants for Item 45523 to apply. The direct Medicare rebate is just over $1,000, but qualifying for Item 45523 is what enables private health fund cover of hospital and anaesthetic costs, which is where the substantial cost saving comes from. Eligibility is determined by clinical presentation and documentation, not patient preference.
How much is the Medicare rebate for breast reduction?
The Medicare rebate for Item 45523 is just over $1,000 AUD, which represents 75% of the MBS scheduled fee for the procedure. Private surgeons charge private fees that exceed the scheduled fee, so Medicare covers the scheduled-fee portion and the remainder is a gap. The real financial value of qualifying for Item 45523 comes from unlocking private health fund cover, which can reduce total out-of-pocket cost by $5,000 or more when top-tier private health insurance is in place.
What clinical criteria do I need to meet for Item 45523?
Two main criteria apply. First, macromastia — clinically enlarged breasts, assessed by a combination of breast weight, volume, chest wall measurements, and overall proportion. Second, documented pain in the neck or shoulder region related to the weight of the breasts. Both criteria need to be met, supported by evidence including GP documentation of symptoms over time, specialist examination, clinical photographs, and often volumetric assessment. Conservative treatment history (physiotherapy, bra fitting, weight management) is also typically required.
Does private health insurance cover breast reduction?
Private health insurance may cover the hospital and anaesthetic components of breast reduction surgery, but only if the procedure has a valid MBS item number AND the patient meets Medicare eligibility criteria. Item 45523 cover is often limited to top-tier policies. It’s essential to verify with your specific fund before booking surgery that your policy covers Item 45523 at your current level of cover. Cosmetic breast reduction (without Medicare eligibility) is not covered by private health insurance.
How long does the Medicare breast reduction process take?
The process from first GP visit to surgery typically runs several months when Medicare eligibility is being pursued. This includes GP consultation and documentation of symptoms over time, initial specialist consultation, any additional conservative management or investigations required, minimum two AHPRA consultations with the specialist, psychological evaluation, mandatory cooling-off period, private health insurance verification, and scheduling of surgery at an appropriate hospital. Patients should factor this timeline into their planning rather than expecting a rapid pathway to surgery.
Consult with Dr Scott J Turner
If you’ve been told by your GP that your symptoms may meet breast reduction criteria, or if you’re trying to assess your own clinical picture before proceeding, the next step is a consultation where your eligibility can be formally evaluated.
Dr Turner consults at his Sydney clinics in Bondi Junction (Eastern Suburbs) and Manly (Northern Beaches). He also sees patients in Brisbane, Canberra, and Newcastle. Surgery is performed at accredited Sydney private hospitals.
Before booking a consultation, arrange a GP appointment to discuss your symptoms and obtain a referral. The GP referral is required under AHPRA guidelines regardless of Medicare eligibility, and documentation of symptoms in your medical records is part of the evidence base for Item 45523 eligibility.
