Anaesthetist Fees Explained: what you'll actually pay.
A plain-English guide to one of the most confusing bills in Australian healthcare — with an interactive estimator showing your likely out-of-pocket cost, and the single most important question to ask before surgery.
The anaesthetist's bill is the one most patients don't see coming.
If you're reading this, you've probably either had surgery and been blindsided by an unexpected bill from the anaesthetist, or you're about to have surgery and trying to work out what you're in for.
You're not alone in finding this confusing. You usually didn't choose your anaesthetist. You might not have met them until the morning of the operation. And by the time the invoice arrives, the procedure is over and the decisions are already made.
This page explains, in plain English, how anaesthetist fees are calculated, what you're likely to pay, and the specific questions to ask before your surgery to avoid surprises afterwards.
Three separate bills, one confusing system.
A single private surgery in Australia generates three independent invoices. The hospital, the surgeon, and the anaesthetist each bill separately.
| Bill | Charges for | Typical handling |
|---|---|---|
| Hospital | The admission, theatre time, recovery, nursing | Usually settled directly between hospital and your fund. You might pay an excess. |
| Surgeon | The operation itself | Usually quoted in advance. Often quoted as “no gap” if you've chosen a participating surgeon. |
| Anaesthetist | The anaesthesia care from induction to recovery handover | Frequently not quoted in advance. Frequently invoiced after the procedure. |
That third one is what this page is about. It's also the smallest of the three — anaesthesia is typically a fraction of what the surgeon and hospital charge — but it's the one most patients hear about last.
How anaesthetist fees are calculated
Every anaesthesia service in Australia is billed under the Medicare Benefits Schedule using a system called the Relative Value Guide (RVG). The total fee is the sum of three components multiplied by a per-unit dollar value:
- Base units
- A fixed number assigned by the MBS to your procedure. A knee arthroscopy is 4 base units. A cataract is 5. A total knee replacement is 7. A caesarean section is 12.
- Time units
- Roughly one unit per 15 minutes of anaesthesia time, measured from induction to recovery handover. A 60-minute procedure adds 4 time units.
- Pre-operative consultation
- Usually 2 units for the standard pre-op review with your anaesthetist.
Those numbers are added to give total units, then multiplied by the anaesthetist's per-unit fee. Every anaesthetist sets their own rate; Australian competition law prohibits anaesthetists from agreeing on a common fee.
Medicare's rebate is calculated against a fixed per-unit value of $23.10, indexed annually each July. Your fund pays a top-up on top of Medicare's portion. Whatever your anaesthetist charges above the combined Medicare + fund rebate is your out-of-pocket gap.
Australian anaesthetists typically charge between $45 and $95 per unit, with most clustering between $55 and $80. The AMA's recommended rate, indexed each November, is currently $110 per unit — though most private anaesthetists charge below that.
Estimate your anaesthetist gap.
Select your state, fund, procedure, and your anaesthetist's quoted per-unit fee. The estimator shows what Medicare and your fund will cover, what you'll likely pay, and how your fund compares to others in your state.
Anaesthetist fee gap estimator
Estimates based on the ASA Relative Value Guide 2025. Major funds cap your out-of-pocket at $500 per anaesthetist per procedure when the anaesthetist participates in the fund's known-gap scheme.
This calculator does NOT include:
- Age modifiers (under 4 years or over 75 years of age)
- ASA physical status modifiers (for significant medical conditions)
- Emergency or after-hours surcharges
- Add-on items: arterial line monitoring, central venous catheterisation, regional or nerve blocks for postoperative pain, transoesophageal echo, and others
Your final fee may be higher than shown. Always rely on your anaesthetist's written informed financial consent.
What you'll actually pay — realistic ranges.
The calculator shows your estimate, but here's the honest big picture for context.
If your anaesthetist participates in your fund's gap scheme — the most common case for routine elective surgery in private hospitals — your out-of-pocket anaesthetist gap will typically land between $0 and $500. Many patients pay nothing under a no-gap arrangement. Most others pay a known gap somewhere under the $500 cap.
If your anaesthetist doesn't participate in your fund's scheme for your procedure, your gap can be substantially larger — sometimes $1,000 to $2,000 for longer procedures, because your fund drops back to paying only the legally required 25% of the MBS rate and the $500 cap no longer applies.
Compared to the rest of your surgical bill, the anaesthetist's portion is usually the smallest. A typical private elective procedure might leave the patient out of pocket for $200–$500 on the hospital excess, $300–$2,000 on the surgeon, and $0–$500 on the anaesthetist. Yours will vary.
The single biggest factor in what you pay is not which fund you're in, and not which anaesthetist will be at your surgery — it's whether that anaesthetist participates in your fund's scheme for your specific procedure.
Why someone on a different fund paid less for the same surgery
It's the most common comparison patients make, and it usually has a more boring explanation than people expect.
Each major Australian fund publishes its own per-unit rebate schedule and its own gap scheme rules. The fund sets the terms; anaesthetists who want to participate in a scheme sign up with that fund on the fund's published terms. There is no negotiation between funds and anaesthetists about the rate — if an anaesthetist opts in, they accept whatever rebate that fund has set, and if they don't, they bill the patient at their own rate and the fund pays only its mandatory minimum.
Between major funds, the published rebates are real but small differences: typically a $5–$15 difference in total gap for the same procedure at the same anaesthetist's fee. You can see this in the fund-comparison panel inside the calculator above.
The bigger swing isn't between funds — it's between participating and non-participating anaesthetists. If your friend's anaesthetist used the gap scheme and yours didn't, your friend probably paid nothing and you might have paid $1,000+. The fund choice is a footnote next to that decision.
The one question that matters most.
Before any planned procedure, ask your surgeon's office for the name of the anaesthetist who will treat you, then phone the anaesthetist's rooms and ask:
“Do you participate in [my fund]'s known-gap or no-gap scheme for [my procedure]?”
That sentence is the most important single question on this entire page. The answer tells you almost everything you need to know.
- “Yes, no-gap” → You'll pay nothing extra for the anaesthetist.
- “Yes, known-gap” → Your out-of-pocket is capped at $500 by the fund's scheme.
- “No” → You may face a significantly larger bill. Either request a different anaesthetist, request a written quote, or consider the public hospital alternative covered below.
Anaesthetists choose scheme participation on a case-by-case basis. Even an anaesthetist listed in your fund's provider directory can choose not to use the scheme for a particular procedure. That's why the phone call is worth making.
Questions to ask your anaesthetist.
Most people don't realise this, but you have every right to ask about costs upfront — and a good anaesthetist will welcome the conversation.
Agreeing to costs in advance is called Informed Financial Consent (IFC). For surgery with anaesthesia, the standard is that you should receive a written estimate that's tailored to your circumstances, well before the procedure. It should outline the anaesthetist's fee, the expected Medicare and fund rebates, and your likely out-of-pocket cost.
In practice, you'll often receive this information about your anaesthetist as part of your surgeon's paperwork, since the surgeon coordinates your overall care. If you don't, ask your surgeon's office for the anaesthetist's name and contact details, and call the anaesthetist's rooms directly.
Take this list with you
- Do you participate in my fund's gap scheme for this procedure? The most important question. Covered above.
- What is your per-unit fee, and approximately how many total units will my procedure attract? Multiply the two for your estimated total fee before rebates. Plug both numbers straight into the calculator above.
- What's my likely out-of-pocket after Medicare and my fund pay their share? A good answer is a specific dollar figure or a tight range.
- Will you give me written Informed Financial Consent before the procedure? Per the Medical Board's Code of Conduct, IFC for complex procedures should be in writing. The document should itemise your fee and disclose all expected charges.
- Are there any extra charges I should expect? Specifically ask about after-hours or weekend surcharges, age modifiers (under 4 or over 75), ASA physical status modifiers, and add-on items like arterial line monitoring, nerve blocks, or transoesophageal echo.
- When and how will I be billed? Some practices bill your fund directly and only invoice you for the gap. Others invoice the full amount upfront and you claim back.
- Will you personally be the anaesthetist on the day, or might a colleague substitute? Avant's professional guidance is that a substitute should generally charge the fee the patient was originally quoted, and may only charge more after prior, timely disclosure. If a higher bill arrives from a substitute without prior disclosure, you have reasonable grounds to query it.
How to find a no-gap anaesthetist for your fund
Every major Australian fund publishes a searchable directory of doctors who participate in their gap scheme. Searching before your surgeon refers you gives you the option to request someone specific.
- Bupa members
- Search the Bupa Members First specialist finder on the Bupa website. Filter for “Anaesthetics” and your hospital's suburb.
- Medibank Private members
- Use the Medibank Members' Choice provider search. Medibank only offers a known-gap scheme for anaesthesia (no no-gap option), with the $500 cap.
- HCF members
- Search HCF Medicover via the Healthshare provider directory linked from HCF's website. The directory flags both no-gap and known-gap participants.
- NIB members
- NIB runs two networks: GapSure Anaesthetics — the anaesthetist-specific scheme at a flat $45/unit (no out-of-pocket gap permitted on procedures with fewer than 5 base units, known-gap up to $500 otherwise) — and MediGap, the broader medical-specialist scheme. Anaesthetists may participate in either. Confirm with your anaesthetist's rooms which network applies, then use NIB's Find a Provider tool to verify.
- HBF members
- HBF runs its own anaesthesia agreement, the Specialist Anaesthetist Schedule, in Western Australia only. WA members search for participating anaesthetists via the HBF website. Outside WA, HBF participates in AHSA Access Gap Cover instead — so non-WA HBF members effectively use the same AHSA rates as members of CBHS, Defence Health, Peoplecare, and other AHSA funds (including the $500 known-gap cap).
- St Luke's Health members
- Search the St Luke's Health provider finder on the St Luke's website.
- Members of AHSA-administered funds
- This includes ACA Health, AIA Health Insurance, Australian Unity, CBHS, Defence Health, Doctors' Health Fund, Frank, GMHBA, HCi, Health Partners, HIF, Latrobe Health Services, myOwn, Navy Health, Nurses & Midwives Health, Onemedifund, Peoplecare, Phoenix Health, Police Health, Queensland Country, RACQ Health, Reserve Bank Health Society, see-u by HBF, Teachers Health, TUH, UniHealth, Union Health, Westfund, and HBF outside WA. Search the Access Gap Cover directory at ahsa.com.au.
You've had surgery and the bill is bigger than expected.
This is a more common scenario than the calculator above acknowledges. If you're reading this after the procedure — whether elective and unexpected, or an emergency where there was no opportunity for advance discussion — you have fewer options than the patient who reads it before. But you're not without recourse.
First, check the invoice line by line. It should show MBS item numbers, units billed, the per-unit rate, the Medicare rebate, your fund's contribution, and the gap. If any of that is missing, request an itemised invoice. You're entitled to one.
Check whether the anaesthetist applied your fund's gap scheme. If the invoice shows the fund's contribution at the known-gap rate, the scheme was used and the gap is what it is — but it shouldn't exceed $500 from any single anaesthetist. If the gap is much larger than that, the scheme was probably not used.
Phone the anaesthetist's billing office or practice manager. Ask politely whether the gap scheme was used. If it wasn't, ask why. Many practices have discretion to discount for genuine hardship.
Contact your fund. They can confirm whether the anaesthetist is registered with the scheme and may be able to re-process the claim under the gap arrangement if both parties agree.
If you can't resolve the matter directly with the anaesthetist's office, where you go next depends on the issue:
- Disputes about how your fund handled the claim — for example, the fund refused to apply the known-gap scheme when you believe they should have — go to the Commonwealth Ombudsman (Private Health Insurance) on 1300 362 072 or ombudsman.gov.au. The Ombudsman investigates disputes about private health insurance arrangements.
Your hospital excess is not the same as your anaesthetist's gap
These two things confuse more patients than almost anything else in the system.
A hospital excess is a fixed amount you've agreed to pay when you're admitted to hospital — usually $250, $500, or $750 — in exchange for a lower premium. It applies to your hospital cover only, and is paid once per admission. It has nothing to do with the anaesthetist.
A medical gap, including the anaesthetist's gap, is the difference between what your anaesthetist charges and what Medicare plus your fund pay. It's separate from the excess. Every doctor involved in your care can charge a gap independently.
On a typical private elective procedure you might pay: a hospital excess to the hospital, a surgeon's gap to the surgeon, an anaesthetist's gap to the anaesthetist, and possibly a small co-payment depending on your policy. The calculator on this page shows only the anaesthetist's portion of that.
The public hospital alternative is real.
If you're staring at a steep anaesthetist gap quote and the procedure is non-urgent, you have an option many patients forget exists: public hospital care.
As a public patient in a public hospital, Medicare covers the full cost of your treatment, including all medical fees (surgeon, anaesthetist, assistant). You'll have no out-of-pocket cost for medical fees. The trade-offs are real — you don't choose your surgeon, the wait can be long, and elective procedures are triaged by clinical urgency rather than convenience.
You can also be a private patient in a public hospital. You choose your doctor, your private cover applies, and your fees work the same way as a private hospital — including the possibility of an anaesthetist gap. Some patients prefer this because they get to choose the surgeon while keeping their cover relevant.
This isn't a recommendation either way — there are genuine clinical reasons to choose private care, including shorter waits, choice of surgeon, and continuity of care. But if cost is the primary concern, the public-as-public option exists.
Frequently asked questions.
Thirteen questions patients actually ask us. If yours isn't here, the calculator above probably answers it — or you can phone the practice and ask directly.
Why is there still a gap with private health cover?
What should be in a good written Informed Financial Consent (IFC)?
A thorough IFC for a procedure with anaesthesia should include:
- The relevant MBS item numbers and Medicare rebates that apply
- The doctor's fee for each item
- A note about hospital costs, or where to find them
- A recommendation to check with your private health fund
- A total cost estimate, clearly labelled as an estimate or range if exact figures aren't possible
- Information about possible variations if circumstances change
For complex procedures, IFC should be in writing, tailored to your circumstances, and given to you well before the procedure.
What's the difference between “no-gap” and “known-gap”?
Is the $500 gap cap guaranteed?
Why is my friend's bill so different from mine?
Can I negotiate the anaesthetist's fee?
Can I choose my anaesthetist?
What if my surgery was an emergency or booked at short notice?
The Australian Society of Anaesthetists (ASA) acknowledges that obtaining IFC is genuinely harder for anaesthetists than for other specialists — particularly for day surgery, day-of-surgery admission (DOSA), and emergency patients.
ASA's position recognises three tiers:
- For elective surgery, IFC should be obtained wherever possible.
- For short lead-time bookings (late additions to operating lists, urgent cases, short-notice elective), anaesthetists should attempt to provide fee information prior to admission to hospital, or otherwise as soon as practical and appropriate.
- For genuine emergency cases, patient safety is the first priority and preoperative IFC may not be appropriate. Fee information should be provided as soon as practical after the procedure.
The underlying mechanics are the same regardless: Medicare pays 75% of MBS, your fund pays at least 25%, and the $500 known-gap cap still applies if your anaesthetist participates. After-hours and emergency MBS items often carry loadings that increase your fee above the calculator's estimate.
Why is caesarean section anaesthesia so expensive compared to other procedures?
What happens if my anaesthetist isn't in my fund's scheme?
Does my hospital excess apply to the anaesthetist's bill?
Do I pay the anaesthetist directly, or does the fund?
If I'm in the public system, do I pay anything for the anaesthetist?

Limitations of the estimator
The calculator produces an approximation based on average procedures and the most favourable gap scheme available under your fund. It does not account for, and your final bill may be higher because of:
- ASA physical status modifiers if you have significant medical conditions
- Age modifiers if you are under 4 years of age or over 75
- After-hours, weekend, or emergency loadings
- Procedure-specific complexity or longer-than-average operative time
- Add-on items including arterial line monitoring, central venous catheterisation, regional or nerve blocks for post-operative pain, and intra-operative transoesophageal echocardiography
- Charges from other practitioners (surgeon, assistant surgeon, perfusionist)
- Hospital accommodation, theatre fees, prostheses, or any hospital excess or co-payment

Our business
Fast Tracking provides specialist billing services to anaesthetists. We issue invoices to patients on behalf of the anaesthetists we represent, but anaesthetists are our clients, not patients — we do not sell health insurance and we don't act as financial advisers to patients. This page exists because patients regularly contact our office with questions about their anaesthetist's bill, and we believe clearer public information makes the system better for everyone.
