Public vs Private Joint Replacement: Medicare, Health Funds, Wait Times and What You’ll Pay

Key Takeaways

• The public pathway covers your care through Medicare with little or no out-of-pocket cost, but you have less choice of surgeon and timing and usually a longer wait.
• The private pathway lets you choose your surgeon and often means weeks rather than months, with costs shaped by your fund cover and the fees charged.
• Private joint replacement generally requires gold tier hospital cover, or a silver plus policy that includes it, with a 12-month waiting period typical for pre-existing arthritis.
• The surgeon and anaesthetist gap is your largest variable cost, so ask for a written estimate before booking.

Deciding to have a knee or hip replaced is a significant step, and weighing up public versus private joint replacement can feel almost as daunting as the surgery itself. The questions tend to arrive all at once. How long will you wait? What does Medicare cover? Do you need private health insurance, and if you have it, what will you still pay? These are practical concerns, and they deserve clear, honest answers.

As an orthopaedic and physiotherapy clinic on Sydney’s North Shore, we sit with people working through this exact decision. Some come to us early, with joint pain they hope to manage without an operation. Others have reached the point where a replacement is on the table and they want to understand the road ahead. Our role is to help you see the full picture so you can make a choice that suits your health, your timeline, and your budget.

The two pathways differ most in what Medicare and your health fund cover, how long you might wait, and what you could pay out of pocket. We lead with conservative, movement-first care, because for many people surgery is one option in a longer pathway rather than the automatic first answer.

Where Joint Replacement Sits in Your Care

Joint replacement is rarely the first step. For most people living with a worn knee or hip, there is real ground to cover before an operation becomes the right move, and understanding that ground helps you judge when surgery is worth considering:

The case for conservative care first

Osteoarthritis (OA) is the most common reason people consider joint replacement, and it often responds well to non-surgical care, at least for a time. Tailored exercise, physiotherapy, strength work, and sensible pain management can reduce symptoms and keep you moving. For many people, a structured program delays the need for surgery, and for some it removes that need altogether.

This is usually where our team starts. We assess how the joint is affecting your daily life, then build a personalised care program around your goals, whether that is walking the dog, returning to sport, or sleeping through the night without pain. Active rehabilitation will not regrow worn cartilage, but it can change how much your symptoms limit you day to day.

The point where surgery enters the conversation

Surgery becomes worth discussing when pain and stiffness persist despite good conservative care, when the joint disrupts sleep and daily function, and when imaging shows advanced joint damage. There is no single threshold that applies to everyone. The right timing depends on your symptoms, your goals, and an assessment by your treating doctor.

A specialist review helps clarify whether a replacement is likely to help, and when. At MTP Health, that review sits within our orthopaedic team, so a conservative plan and a surgical opinion sit side by side rather than running as two separate journeys.

The joints most commonly replaced

Knees and hips are the two joints replaced most often in Australia. Total knee replacement (TKR) and total hip replacement (THR) are well-established procedures that aim to reduce pain and restore movement when a joint is badly worn.

Which joint is involved affects cost, recovery, and typical wait times. The pathway decisions are broadly similar whether you are managing knee conditions or hip conditions.

How the Public and Private Pathways Differ

The public and private systems both deliver joint replacement to a high standard, but they differ in who carries the cost, how much choice you have, and how long you are likely to wait. Knowing the shape of each helps you weigh them against your own situation:

The public hospital pathway

In the public system, you are treated as a public patient in a public hospital, and Medicare funds your care. You generally need a general practitioner (GP) referral to a public orthopaedic outpatient clinic, where a specialist assesses you and, if appropriate, places you on a waiting list. The hospital allocates your surgeon and your surgery date based on clinical priority.

The main appeal is cost. As a public patient, your treatment is typically covered with little or no out-of-pocket expense. The trade-offs are less choice over your surgeon and timing, and often a longer wait.

The private hospital pathway

In the private system, you choose your surgeon and are treated in a private hospital. You usually still start with a GP referral, then book a consultation with the specialist you have selected. Your surgery date is arranged between you, the surgeon’s rooms, and the hospital, which often means a shorter wait.

The trade-off here is cost. Private care involves fees from several parties, and what you pay depends on your health fund cover and the fees charged.

The freedom to move between them

You are not locked into one system from the start. Many people use the public system for their initial assessment and imaging, then decide whether to wait as a public patient or move to the private pathway. You can also seek a private consultation for an opinion while you remain on a public waiting list.

If you choose private surgery after being listed publicly, you generally come off the public waiting list once your procedure is booked. Your treating doctor and the hospital can explain how this works in your situation.

What Medicare Covers in Each Setting

Medicare sits behind both pathways, but it plays a very different role depending on whether you are treated as a public or a private patient. Understanding the Medicare Benefits Schedule is the key to reading any quote you are given:

The role of the Medicare Benefits Schedule

The Medicare Benefits Schedule (MBS) is the government list of medical services Medicare helps pay for, each with a set scheduled fee. You can look these up on MBS Online. The scheduled fee is not the same as what a surgeon actually charges, and that gap is where many out-of-pocket costs come from.

For joint replacement, the MBS lists the relevant surgical items and their scheduled fees. How much of that fee Medicare returns depends entirely on the setting in which you are treated.

The cover for public patients

As a public patient in a public hospital, Medicare and the public system cover the cost of your joint replacement, including the surgeon, the anaesthetist, the hospital stay, and a standard implant. This is the central strength of the public pathway. The main consideration is usually not the bill but the wait.

The cover for private patients

As a private patient, Medicare pays 75% of the MBS scheduled fee for the surgeon and anaesthetist. Your private health fund is generally required to pay at least the remaining 25% of that scheduled fee, and it also contributes towards hospital and implant costs depending on your policy.

The catch is that surgeons and anaesthetists may charge above the scheduled fee. Where that happens, the difference between the fee charged and the combined Medicare and fund benefit is yours to pay, and this gap is the main reason private surgery carries out-of-pocket costs.

How Private Health Insurance Shapes Your Cover

If you are leaning towards the private pathway, your health fund policy does much of the heavy lifting, but only if it includes the right cover and your waiting periods are served. A few features decide whether you are protected or exposed:

The hospital cover tier you need

Joint replacement sits in the joint replacements clinical category, which is generally included only in gold tier hospital cover, and in some silver plus policies that add categories on top of their base tier. Lower tiers often exclude it. If your policy does not include joint replacements, your fund may pay little or nothing towards a private procedure.

It is worth checking your policy documents or calling your fund before you commit to anything. Confirm that joint replacements are included and that the joint you need is covered.

The waiting periods that apply

Health funds apply waiting periods before you can claim. For joint replacement, a waiting period of 12 months usually applies to pre-existing conditions, and knee or hip arthritis that was present before you joined is typically treated as pre-existing. A shorter waiting period generally applies to genuinely new conditions.

If you switch funds or upgrade your policy, waiting periods you have already served on equivalent cover usually carry across, though moving to a higher level of cover can bring its own waiting period. Your fund can confirm exactly where you stand.

The role of the Prescribed List for implants

The implant itself is handled through the government’s Prescribed List of Medical Devices and Human Tissue Products. When a device is on that list and your policy covers the procedure, your fund is required to pay a benefit for it. In practice, this often means no separate out-of-pocket cost for a standard, listed implant.

This is a useful protection to understand, because it separates the cost of the device from the fees charged by your surgeon and anaesthetist, which are where gaps more commonly arise.

What the Wait Can Look Like

Wait time is often the deciding factor between the two pathways, and it is the area where public and private differ most sharply. The figures below are general indicators, and your own wait can be shorter or longer depending on your circumstances:

The wait in the public system

Public hospital waiting times are reported each year by the Australian Institute of Health and Welfare (AIHW). Across all elective surgery in 2024 to 2025, half of patients were admitted within about 45 days, but major joint replacement typically sits well above that overall median. You can explore the current figures through the AIHW elective surgery waiting times data.

In recent reporting, both TKR and THR have been among the longer waits, with public medians commonly running to several months. These figures shift year to year and vary by state and hospital, so treat them as a guide rather than a promise.

The wait in the private system

In the private system, waiting times are usually shorter because your surgery is booked directly rather than through a public waiting list. For many people this can mean weeks rather than months, depending on the surgeon’s availability and your readiness for surgery.

AIHW reporting has consistently shown that, within the public system, patients who use private health insurance to fund their admission tend to be admitted sooner than public patients. The private pathway can suit people whose pain and loss of function make a long wait hard to manage.

The factors that change your wait

Several things influence how long you wait in either system. Clinical urgency is assessed and prioritised, so more severe cases may be seen sooner. Your location, the specific hospital, the surgeon’s schedule, and seasonal demand all play a part as well.

Your own readiness matters too. Improving your general health, fitness, and any other medical conditions before surgery can affect when you are cleared to proceed, regardless of pathway.

What You Might Pay Out of Pocket

Out-of-pocket cost is the part people find hardest to pin down, because it is built from several separate fees rather than one figure. Knowing the components lets you ask the right questions and avoid surprises:

The surgeon and anaesthetist gap

In the private system, your largest variable cost is usually this surgeon and anaesthetist gap. As an indicative guide, surgeon fees for a joint replacement often range from about $3,000 to $8,000, broadly in line with Australian Medical Association (AMA) starting rates, with a Medicare rebate reducing what you pay. Some practitioners take part in no gap or known gap schemes that limit or remove it, while others charge above the scheduled fee.

The amount varies widely by doctor, procedure, and state, which is why no general figure can reliably predict what you will pay.

The hospital excess and theatre costs

Most hospital policies carry an excess, which is the amount you agree to pay towards a hospital admission in exchange for a lower premium. You will usually pay this excess when admitted for your replacement. Theatre and accommodation costs are generally covered by your fund when your policy includes the procedure, though it is worth confirming.

If you are self-funding without insurance, private hospital, theatre, and accommodation costs can be substantial and are charged on top of the surgeon and anaesthetist fees. For most people, this makes appropriate cover the more manageable route into the private system.

The questions worth asking first

Before you commit, ask your surgeon’s rooms for a written quote that lists the MBS item numbers, the total fee, the expected Medicare and fund rebates, and your estimated gap. Ask your health fund whether joint replacements are included on your policy, what excess applies, and whether your surgeon and hospital have a gap arrangement with them.

It is also worth asking about the costs that come after surgery, including physiotherapy and rehabilitation, which are an important part of recovery and may be claimable under the extras part of your cover.

Where Robotic-Assisted Surgery Fits

You may come across robotic-assisted joint replacement while researching your options, often described in glowing terms. It helps to understand what the technology actually does, where it is available, and what the evidence currently supports:

The way robotic-assisted surgery works

Robotic-assisted surgery is exactly that: assisted. The surgeon plans and performs the operation, and a robotic arm helps carry out precise, pre-planned bone cuts based on imaging such as X-rays or computed tomography (CT) scans. The technology can support accuracy and alignment, but it does not replace the surgeon’s judgement or skill. At MTP Health, our orthopaedic surgeons offer robotic-assisted joint replacement, with the surgeon controlling the operation throughout.

The availability across public and private

In New South Wales, robotic-assisted joint replacement is mostly available in the private hospital setting. This means access to it can be one more factor in a public versus private decision, particularly if it is something you and your surgeon consider suitable for your case.

Robotic assistance should not be thought of as a premium or paid upgrade. Whether it is appropriate depends on your joint, your anatomy, and your surgeon’s assessment, not on a price tag.

The evidence as it stands

Long-term comparative results for robotic assistance are still emerging, and the pre-operative preparation and post-operative recovery are generally similar to those of conventional surgery.

The sensible approach is to view robotics as one tool among several, and to focus on the experience of your surgeon and the overall plan rather than the technology alone. Your treating specialist can explain whether it is likely to add value in your specific situation.

Moving Forward Without Cost or Wait-Time Surprises

Choosing between public and private joint replacement comes down to trade-offs: cost against waiting time, and choice against convenience. The public pathway offers strong financial protection in exchange for a longer, less flexible wait. The private pathway offers more control and often a shorter wait, with costs that depend on your cover and the fees charged. Neither is the right answer for everyone, and the soundest decision is the one made with clear figures and good advice in front of you.

Wherever you are in that process, you do not have to work it out alone. Our multidisciplinary team can assess your joint, build a movement-first plan, and, where surgery is being considered, help you understand the pathway and the questions to ask. If you would like to take a sensible next step, you are welcome to book an assessment or speak with our team about what might suit your situation.

Frequently Asked Questions (FAQs)

1. Is joint replacement covered by Medicare?

Yes. As a public patient in a public hospital, Medicare and the public system cover the cost of joint replacement, usually with little or no out-of-pocket expense.

As a private patient, Medicare pays 75% of the MBS scheduled fee for the surgeon and anaesthetist, and your health fund and any gap make up the rest. The cover you receive depends on the setting and your policy.

2. Do I need private health insurance for a joint replacement?

No. You can have a joint replacement as a public patient without private cover. Private health insurance is what gives you access to the private pathway, with more choice of surgeon and often a shorter wait.

For private surgery, you generally need gold tier hospital cover, or a silver plus policy that includes joint replacements. It is sensible to check your policy before booking.

3. How long is the wait for a knee or hip replacement?

It varies widely. In the public system, major joint replacement often takes several months, and the figures change each year by state and hospital.

The private system is usually faster, sometimes weeks rather than months, depending on your surgeon’s availability. AIHW publishes current public waiting times if you want to check the latest figures.

4. Why is there still a gap to pay if I have insurance?

A gap arises when your surgeon or anaesthetist charges more than the combined Medicare and fund benefit based on the MBS scheduled fee.

Some practitioners use no gap or known gap schemes that reduce or remove this cost. The clearest way to know your gap is to ask your surgeon’s rooms for a written estimate before surgery.

5. Is robotic-assisted surgery more expensive or better?

Robotic assistance is a tool that may support precision and alignment, and it should not be presented as a premium upgrade or a guarantee of a better result. Long-term comparative evidence is still developing.

In New South Wales it is mostly available privately. Whether it suits you is a clinical decision for you and your surgeon, not a matter of paying more.

6. Can I start with non-surgical treatment first?

Yes, and for many people that is the sensible place to begin. OA often responds to tailored exercise, physiotherapy, and pain management, which can reduce symptoms and delay or avoid surgery.

If conservative care no longer controls your symptoms, a specialist can help you weigh up whether a replacement is the right next step.
