Key Takeaways
- Medicare does not cover breast lift surgery performed for appearance alone. Item 45558 is the exception, and eligibility for it rests on an anatomical finding rather than on why the ptosis developed.
- The threshold is that at least two-thirds of the breast tissue, including the nipple, lies below the inframammary fold, with the nipple at the lowest part of the breast contour.
- Photographic evidence in anterior, left lateral and right lateral views, taken with a marker at the level of the fold, must be in the patient notes. Without it there is no claim.
- Item 45558 is bilateral and claimable once in a lifetime. The schedule fee is $1,375.20 and the benefit is 75% of that, being $1,031.40.
- It is not payable where any prosthesis is inserted, so a lift performed with implants does not attract it.
- Item 45556 is the unilateral equivalent, available only in the context of breast cancer or a developmental abnormality of the breast.
The Medicare question is usually the first one patients want answered, and the answer is more specific than most articles suggest. Medicare does not fund breast lift surgery performed for appearance alone. It does fund mastopexy where a defined anatomical threshold is met and documented, and that threshold applies regardless of what caused the ptosis.
That last point is where a lot of published material goes wrong. Item 45558 is not restricted to reconstruction after cancer, and it is not automatically excluded because the ptosis followed pregnancy or weight loss. What it turns on is the position of the breast tissue and nipple, evidenced photographically.
What follows sets out the two ptosis items, what the criteria require, what documentation is needed, and how private health cover interacts with an eligible item. Full procedure detail sits on the breast lift page, and the breast lift cost guide covers the figures with and without Medicare.
Item 45558 and what it requires
Item 45558 covers correction of bilateral breast ptosis by mastopexy. The descriptor sets two requirements.
The anatomical finding. At least two-thirds of the breast tissue, including the nipple, must lie below the inframammary fold, with the nipple sitting at the lowest, most dependent part of the breast contour. This is a measured finding at examination, not an impression.
The photographic evidence. Anterior, left lateral and right lateral views, taken with a marker placed at the level of the inframammary fold, demonstrating the clinical need for the service, documented in the patient notes. Medicare billing is subject to audit and this is the material an audit looks for.
Three further points follow from the item and its explanatory note.
- It is bilateral, and claimable once in a lifetime.
- It is not payable where any prosthesis is inserted. A lift performed with implants does not attract it, even where the lift component would otherwise meet the threshold.
- The schedule fee is $1,375.20, and the Medicare benefit is 75% of that, being $1,031.40. Schedule fees are indexed periodically, so check the current figure on MBS Online if you are budgeting closely.
What the item does not do is ask why the ptosis developed. Severe ptosis following pregnancy and breastfeeding, or following significant weight loss, can meet the criteria on the anatomy alone. Equally, a patient who is troubled by mild or moderate ptosis does not qualify no matter how much the appearance bothers them, because the two-thirds threshold is not met.
Item 45556: the unilateral item
Item 45556 covers correction of breast ptosis on one side, and it is narrower. It is available only in the context of breast cancer or a developmental abnormality of the breast, and requires photographic evidence, diagnostic imaging evidence, or both, documented in the patient notes.
The explanatory note is specific: the benefit is payable only where the correction is performed unilaterally to match the position of the contralateral breast, and the item is payable only once per patient. No additional benefit is payable if the same procedure is then performed on the other side. Like 45558, it should not be used with the insertion of any prosthesis on the same side.
The schedule fee is $916.85, with a benefit of $687.65.
This is the item that applies where one breast is lifted for symmetry alongside reconstruction of the other. It is not a general-purpose route to a rebate for a one-sided lift.
Where a lift is part of a reduction
A common route to a partial rebate is where the lift is an inherent part of a breast reduction that itself qualifies.
Item 45523 covers bilateral reduction mammaplasty with surgical repositioning of the nipple. Its criteria are macromastia, and pain in the neck or shoulder region. It is not payable where any prosthesis is inserted. Nipple repositioning is built into the item, so the lift component is not billed separately.
Two things are worth correcting here, because both circulate widely. The descriptor does not set a minimum weight of tissue to be removed, and it does not require a documented period of failed conservative management. Those are not criteria in the item. A history of conservative measures and of symptoms recorded over time is useful evidence when a claim is assessed, but it is evidence supporting the stated criteria rather than a criterion in its own right.
Which item applies comes down to the primary clinical indication. Where the operation is a reduction for documented symptoms and the lift is part of the technique, the reduction item applies. Where the operation is a lift and any volume change is incidental, it is not a reduction. The Medicare breast reduction guide covers that item in detail.
Mastopexy after breast cancer treatment
Where mastopexy forms part of reconstructive planning after cancer treatment, the reconstructive pathway rather than the cosmetic one applies, and item 45556 is usually the relevant ptosis item for a contralateral symmetrising lift.
These cases involve coordination between the treating breast surgeon, the oncology team and the plastic surgeon, and the documentation needs to show the reconstructive intent. Items associated with breast cancer excision carry their own interactions with the ptosis items, which is one reason the item selection is made at consultation rather than assumed in advance.
What documentation is required
For a ptosis item, the record needs to carry:
- A GP referral setting out the clinical history and the reason for surgery
- Examination findings recording the position of the nipple relative to the inframammary fold and the proportion of tissue below it
- Standardised photographs in anterior, left lateral and right lateral views, with a marker at the level of the fold
- Imaging reports, where relevant to the case
- Specialist correspondence where the case sits within reconstructive care
- Surgical planning notes
Photographs taken at home do not meet the item’s requirement, because the marker at the fold and the standardised views are part of what is specified. They can still be useful background at a first consultation.
How private health cover interacts
Where an eligible item number applies and you hold hospital cover at a level that includes it, with waiting periods served, the fund covers the hospital and theatre component. Gaps generally remain on the surgeon’s and anaesthetist’s fees depending on the gap arrangement.
Where no item applies, the procedure is cosmetic. Medicare pays nothing, and funds do not contribute to hospital or theatre costs either. The two are linked, which is why the cost difference between an eligible and an ineligible case is substantial.
If you think your case may qualify, it is worth contacting your fund before surgery is booked and confirming four things: whether your level of cover includes the item number, what waiting periods apply, what your gap arrangement is, and whether any pre-existing condition rules affect you.
The consultation framework
The cosmetic surgery guidelines that came into force on 1 July 2023 apply to breast lift surgery whether the procedure is rebated or self-funded. A GP referral is required before the first consultation. A minimum of two consultations with the operating surgeon applies before surgery is booked. Psychological assessment is conducted to confirm suitability. A cooling-off period of at least seven days sits between consent and surgery.
Because eligibility depends on examination findings and standardised photographs, it is assessed at consultation rather than estimated from images sent in advance. An itemised quote follows the second consultation, once the surgical plan is settled and any item number has been confirmed or excluded.
Frequently asked questions
Will Medicare cover my breast lift after pregnancy?
It can, if the anatomy meets the threshold. Item 45558 does not ask why the ptosis developed, so post-pregnancy ptosis is not excluded as a category. What it requires is that at least two-thirds of the breast tissue, including the nipple, lies below the inframammary fold with the nipple at the lowest part of the contour, documented with standardised photographs taken with a marker at the fold. Many patients seeking a lift after pregnancy do not meet that threshold, which is why most post-pregnancy lifts are self-funded, but the assessment is anatomical rather than categorical.
Will Medicare cover my breast lift after weight loss?
The same test applies. Significant weight loss commonly produces the degree of ptosis that meets the two-thirds criterion, and where it does, and the photographic documentation is in place, item 45558 may apply. Where the ptosis is less marked, it will not. The cause of the ptosis is not what the item turns on.
Can I claim Medicare for a breast lift combined with implants?
No. Item 45558 is not payable where any prosthesis is inserted, and item 45556 should not be used with the insertion of a prosthesis on the same side. A lift performed together with implants therefore attracts no ptosis item, even where the lift component would otherwise meet the criteria. Staging the two operations is a clinical decision rather than a billing one, and is discussed separately.
Does private health insurance cover a cosmetic breast lift?
No. Funds contribute where a procedure carries a valid MBS item number and the eligibility criteria are met. A cosmetic lift has neither, so hospital and theatre costs are paid privately, along with the surgeon’s and anaesthetist’s fees. Where an item does apply and your cover includes it, the fund pays the hospital and theatre component and gaps generally remain on the professional fees.
How do I find out whether my situation qualifies?
Through examination and standardised photography at consultation. The measurement that matters is how much of the breast tissue, including the nipple, sits below the inframammary fold, and that is assessed in person rather than from photographs sent in advance. Bringing a GP referral, records of any previous breast surgery or cancer treatment, recent imaging reports, and your fund details makes that conversation specific rather than general.
