Breast surgery can be both medically beneficial and deeply confidence-restoring — but understanding the difference between a mastopexy (breast lift) and a breast reduction is essential when considering your options. While these procedures may appear similar, they address different concerns and are suited to different patient goals.
Below, I’ve broken down the key differences, medical indications, referral requirements, item numbers, and what to expect from the consultation and surgical process.
What Is a Mastopexy (Breast Lift)?
A mastopexy, or breast lift, is designed to reshape and reposition the breast without removing significant breast volume.
A mastopexy focuses on:
Lifting the breast into a more youthful position
Reshaping breast tissue
Repositioning the nipple-areola complex
Removing excess stretched or sagging skin
Correcting breast ptosis (drooping)
Who is mastopexy suitable for?
Patients with sagging breasts after pregnancy, breastfeeding, weight changes or ageing
Patients happy with their breast volume but unhappy with shape or nipple position
Patients wanting a more youthful, lifted contour without reducing size
Does a mastopexy reduce breast volume?
Not significantly. Any volume removed is typically limited to excess skin. The overall cup size usually stays similar.
What Is a Breast Reduction?
A breast reduction focuses on removing excess breast tissue, fat and skin, while also lifting and reshaping the breast.
A breast reduction achieves:
Reduction in breast size and weight
Relief from physical symptoms
Reshaping and lifting of the breast
Repositioning of the nipple
Who is breast reduction suitable for?
Patients who experience:
Neck, back and shoulder pain
Bra strap grooving
Rashes under the breasts
Difficulty exercising
Heavy, disproportionate breasts
Functional impairment or discomfort
Breast reduction is both a medical and reconstructive procedure for many women.
Medical Eligibility, GP Referrals & Medicare Item Numbers
Both mastopexy and breast reduction can fall under Medicare guidelines when medical criteria are met.
Breast Reduction – Medicare Item 45523
Medicare may contribute when there is:
Breast hypertrophy causing chronic physical symptoms
Documented pain or functional impairment
Recurrent rashes, skin breakdown or infections
Failure to respond to non-surgical management
A current GP referral is required to access this item number.
Mastopexy – Medicare Item 45558
Standard cosmetic mastopexy is not covered, but Medicare may assist if:
There has been massive weight loss (generally ≥5 BMI points), and
The patient has documented ptosis with skin irritation or functional concerns
Your eligibility is assessed during consultation and supported by a GP referral.
Private Health Insurance Coverage
When a patient meets Medicare criteria and has the appropriate level of private health cover:
Hospital fees
Theatre fees
Anaesthetist fees
may be partially or fully covered, depending on your insurer and policy.
Cosmetic-only procedures are not covered.
We always provide a detailed itemised quote and guidance once eligibility is confirmed.
Consultation Process: Minimum of Two Appointments
For all breast surgeries performed by Dr Theo Birch, patients have:
Consultation 1 – Initial Assessment
Comprehensive medical and surgical history
Breast examination
Discussion of goals, concerns and desired outcomes
Explanation of the most suitable procedure (lift vs reduction)
Eligibility assessment for item numbers and rebates
Surgical plan and scar pattern discussion
Consultation 2 – Pre-Operative Confirmation
Final measurements
Review of medical photography
Detailed consent process
Review of expected recovery and time off work
Booking confirmation
Discussion of garments, medications and preparation
These two appointments ensure safety, clarity and informed decision-making.
Hospital Stay: Day Surgery or 1-Night Stay
Both mastopexy and breast reduction can be performed as:
Day surgery, where you go home the same day
or
1-night hospital stay, depending on:
procedure complexity
medical conditions
patient preference
drain use or post-operative monitoring
Dr Birch will advise the safest option based on your individual case.
Recovery Expectations
Recovery for both procedures is similar, though reductions may require slightly longer healing.
Typical recovery includes:
2 weeks off work (depending on job type)
Support garment for 6–8 weeks
Avoiding heavy lifting for 6 weeks
Gradual return to exercise from 4–6 weeks
Full scar maturation over 12–18 months
Follow-up appointments with Dr Birch ensure optimal healing and long-term results.
Which Procedure Is Right for You?
Choose Mastopexy If You Want To:
Lift sagging breasts
Improve shape and nipple position
Correct ptosis
Maintain most of your current breast volume
Choose Breast Reduction If You Want To:
Reduce breast size
Relieve physical symptoms
Improve comfort and mobility
Achieve a lighter, more proportionate breast shape
During your consultation, Dr Birch will thoroughly assess your anatomy, goals and medical history to determine which procedure best suits your needs.
