Cost of Medical Procedures Without Insurance in Australia
What do colonoscopies, knee replacements, and other procedures cost without private health insurance in Australia? Full 2026 price guide.


In this guide
Australia's public health system, Medicare, covers treatment in public hospitals at no cost. You pay nothing for a knee replacement or a colonoscopy as a public patient. The trade-off: you wait. The median wait time for elective surgery in a public hospital is 48 days, according to the Australian Institute of Health and Welfare (AIHW). For some procedures, the wait stretches past 12 months. If you go private without insurance, you pay the surgeon, the anaesthetist, the hospital, and the prosthetics out of your own pocket. This guide prices the most common procedures.
How Medical Billing Works in Australia
Every medical service in Australia has a Medicare Benefits Schedule (MBS) item number. The MBS sets a "schedule fee" for each item. Medicare pays 75% of the schedule fee for in-hospital services and 85% for out-of-hospital services. The schedule fee has not kept pace with actual costs. Most specialists charge well above it.
The gap between what Medicare pays and what the doctor charges is your out-of-pocket cost. For a colonoscopy, the MBS schedule fee for the surgeon's component is about $340. Medicare pays 75% ($255). If the surgeon charges $700, you pay $445 out of pocket. That is before the anaesthetist fee and any hospital charges.
Private hospitals charge a daily bed rate, theatre fees, and consumables. A single night in a private hospital costs $800 to $1,500 depending on the facility. Theatre fees for a one-hour procedure run $1,500 to $3,000. These hospital charges form the largest portion of most bills.
Common Diagnostic Procedure Costs
Diagnostic procedures identify what is wrong. You get a colonoscopy to screen for bowel cancer or investigate symptoms. You get a gastroscopy to check your oesophagus and stomach. An MRI scan examines soft tissue injuries. Each has a different price depending on whether you go through a public hospital (free, with a wait) or a private facility (immediate, at full cost).
| Procedure | Public Hospital (Medicare) | Private (Out-of-Pocket Without Insurance) |
|---|---|---|
| Colonoscopy | Free (wait: 2 - 6 months) | $2,000 - $4,500 |
| Gastroscopy | Free (wait: 2 - 6 months) | $1,500 - $3,500 |
| Combined colonoscopy + gastroscopy | Free | $3,000 - $6,000 |
| MRI scan (no contrast) | Free if referred by specialist | $300 - $800 (bulk-billed options exist) |
| CT scan | Free if referred | $200 - $500 |
| Ultrasound | Free if referred | $100 - $300 (often bulk-billed) |
| Skin biopsy | Free (GP referral) | $150 - $400 |
A colonoscopy at a private day surgery in Sydney costs $2,500 to $4,500, depending on the surgeon's fee and whether polyps need removal. The surgeon charges $500 to $1,000. The anaesthetist charges $300 to $600. The facility charges $1,200 to $2,500. Medicare rebates cover a fraction, leaving you with $1,500 to $3,500 out of pocket.
Bowel cancer screening is free for Australians aged 50 to 74 through the National Bowel Cancer Screening Program. You receive a home test kit every two years. If the test detects blood, your GP refers you for a colonoscopy in the public system. This pathway avoids the private cost.
Common Surgery Costs Without Insurance
Surgical costs have three components: the surgeon's fee, the anaesthetist's fee, and the hospital charges (bed, theatre, prosthetics, medication). Medicare rebates reduce the surgeon and anaesthetist fees, but cover zero of the private hospital charges.
| Surgery | Public Hospital | Private (Total Out-of-Pocket) |
|---|---|---|
| Knee replacement | Free (wait: 6 - 18 months) | $20,000 - $35,000 |
| Hip replacement | Free (wait: 6 - 18 months) | $20,000 - $35,000 |
| Hernia repair (inguinal) | Free (wait: 2 - 12 months) | $4,000 - $8,000 |
| Gallbladder removal (laparoscopic) | Free (wait: 1 - 6 months) | $5,000 - $10,000 |
| Cataract surgery (per eye) | Free (wait: 3 - 12 months) | $3,000 - $5,000 |
| Tonsillectomy | Free (wait: 3 - 12 months) | $3,500 - $6,000 |
| Caesarean section | Free | $8,000 - $15,000 |
| Wisdom teeth removal (all four, hospital) | Free (wait: 6 - 24 months) | $2,500 - $6,000 |
| ACL reconstruction | Free (wait: 6 - 18 months) | $8,000 - $15,000 |
| Appendectomy (emergency) | Free | $5,000 - $10,000 |
A private knee replacement in Melbourne costs $25,000 to $35,000. The surgeon charges $5,000 to $8,000. The anaesthetist charges $1,500 to $3,000. The hospital charges $15,000 to $20,000 for a three to five night stay, theatre time, and the prosthetic joint ($4,000 to $8,000 for the implant alone). Medicare rebates reduce the surgeon and anaesthetist portions, but the hospital bill remains in full.
Emergency surgeries (appendectomy, emergency caesarean) happen in the nearest hospital regardless of insurance status. If the ambulance takes you to a public hospital, Medicare covers everything. If you arrive at a private emergency department, the hospital may charge private rates. You can request a transfer to a public hospital.
Maternity and Pregnancy Costs
Public maternity care through a hospital midwifery program costs nothing. You see midwives for antenatal appointments and give birth in a public hospital. An obstetrician attends if complications arise. This is standard, safe care. About 70% of Australian births happen in public hospitals.
Going private means choosing your obstetrician and having them attend every appointment and the birth. The out-of-pocket cost for private obstetric care without insurance ranges from $8,000 to $20,000. This covers the obstetrician's management fee ($3,000 to $8,000), delivery fee ($1,500 to $4,000), hospital accommodation ($4,000 to $8,000 for a two to four night stay), and anaesthetist fees if you have an epidural ($500 to $1,500).
If you plan a private birth, check whether the obstetrician offers a known out-of-pocket fee upfront. Many provide a written estimate covering all scenarios (vaginal delivery, caesarean, complications). Get this in writing before you commit.
When Private Health Insurance Saves You Money
Hospital cover (the component of private health insurance that covers procedures) costs $150 to $350 per month for a single person, depending on the excess and inclusion level. A policy with a $750 excess and mid-level hospital cover costs about $180/month ($2,160/year). You should also understand life insurance costs in Australia as part of a broader protection strategy.
A single knee replacement at $30,000 out-of-pocket equals 14 years of premiums at $2,160/year. If you never need another procedure, insurance loses on pure maths. But most people over 50 need multiple procedures: cataracts (both eyes), a joint replacement, a colonoscopy every five years, and potential cardiac work. The numbers shift when you combine several procedures over a decade.
The Medicare Levy Surcharge (MLS) adds another calculation. If you earn over $93,000 as a single (or $186,000 as a family) and do not hold hospital cover, the ATO charges 1% to 1.5% of your taxable income as a surcharge. Someone earning $120,000 pays $1,200/year in MLS. A basic hospital policy costs about the same, so you get coverage for no extra cost. Our guide to health insurance tax deductions explains MLS thresholds and offsets in detail.
The Lifetime Health Cover (LHC) loading penalises late joiners. If you first take out hospital cover after age 31, you pay a 2% loading for every year past 30. A 40-year-old joining for the first time pays 20% more than base premiums, and that loading stays for 10 continuous years of cover. The longer you wait, the more you pay.
How to Reduce Out-of-Pocket Medical Costs
Ask your surgeon for an itemised quote before any procedure. The quote should list every fee: surgeon, assistant surgeon (if required), anaesthetist, hospital, prosthetics, and pathology. Compare quotes from two specialists. Fees for the same procedure vary by 50% to 100% between doctors in the same city.
Use the Medical Costs Finder tool on the Australian Government's health website. It shows the median out-of-pocket cost for common procedures by state. This gives you a benchmark before you accept a quote.
Ask whether the surgeon participates in a gap cover scheme. Medibank, Bupa, HCF, and NIB have agreements with certain surgeons to cap the gap at a known amount ($0 to $500). If you hold insurance, choosing a gap-scheme surgeon saves thousands.
Consider day surgery over overnight hospital stays where clinically appropriate. A laparoscopic gallbladder removal as a day case costs $5,000 to $7,000. The same procedure with an overnight stay costs $7,000 to $10,000. Discuss this option with your surgeon.
Claim what you can at tax time. Out-of-pocket medical expenses above certain thresholds may qualify for the net medical expenses tax offset (though this is being phased out for most taxpayers). Check with your accountant or the ATO website for current eligibility.
If you need a procedure and cannot afford the private cost, ask your GP to add you to the public hospital waiting list. The GP writes a referral to a specialist at the public hospital outpatient clinic. You see the specialist for free, and they add you to the surgical waiting list. Urgent cases (cancer, severe pain, loss of function) get priority. Category 1 patients receive surgery within 30 days. Category 2 within 90 days. Category 3 within 365 days.
Some public hospitals offer shorter wait times than others. In NSW, the Bureau of Health Information publishes wait time data by hospital. You can request a referral to a specific public hospital with shorter queues. Ask your GP which hospitals in your area have the lowest median wait for your procedure.
Payment plans exist at many private hospitals. Ramsay Health Care (which operates over 70 private hospitals in Australia) and Healthscope both offer interest-free payment plans for out-of-pocket costs. Some surgeons accept payment plans for their fees as well. Ask before your procedure. This does not reduce the total cost, but it spreads the financial hit across 6 to 12 months.
