Does Medicare Pay for an Anaesthetist? The 2026 patient guide.

Yes — Medicare pays a rebate for anaesthesia, but only 75% of the MBS schedule fee when you're a private inpatient. Anaesthetists charge above that rate; the difference is the “gap.” Most private patients pay nothing because the anaesthetist uses their fund's no-gap or known-gap scheme. About 1 in 4 patients pay an average gap of $140.

Here's exactly how the system works, what you'll likely pay, and how to make sure you're not caught off guard.

Key
takeaways
i.

Medicare pays 75% of the MBS schedule fee — not 75% of what the anaesthetist actually charges.

ii.

Your fund pays at least 25% of the MBS fee by law — and more if your anaesthetist uses their gap scheme.

iii.

The MBS unit fee is $23.10 (from 1 July 2025); your anaesthetist typically charges $55–$80 per unit.

iv.

Most major funds cap your gap at $500 per doctor — but only if your anaesthetist participates in the scheme.

v.

3 in 4 private patients pay nothing. The 1 in 4 who do pay average $140.

vi.

Ask one question before surgery: “Do you participate in my fund's gap scheme for this procedure?”

01The Short Answer

So — does Medicare pay for the anaesthetist?

Yes, but only partly. When you're admitted as a private patient, Medicare pays 75% of the Medicare Benefits Schedule (MBS) fee for each anaesthesia item, and your private health fund must, by law, pay at least the remaining 25%. Together that covers 100% of the MBS fee — but the MBS fee sits well below what most anaesthetists actually charge, so there's often a difference left over. That difference is the gap.

Why does the gap exist at all? The MBS unit fee was effectively frozen between 2012 and 2019 while the real cost of running a practice kept rising. To stay viable, anaesthetists charge above the MBS rate — and the government rebate hasn't caught up. The gap is the space between what an anaesthetist charges and what Medicare and your fund pay between them.

For most patients, that gap never reaches your pocket. If your anaesthetist participates in your health fund's no-gap or known-gap scheme, the fund tops up the payment and you pay either nothing or a capped amount (usually a maximum of $500). It's only when an anaesthetist doesn't use a scheme — or charges above the known-gap ceiling — that a larger bill can land.

So the real question isn't “does Medicare pay for an anaesthetist?” It's “will my anaesthetist use my fund's gap scheme?” — and that's a question you can ask before your surgery.

Two anaesthetists at the same hospital can produce wildly different bills — entirely depending on whether they choose to use your fund's gap scheme for your procedure.
02How It's Calculated

An anaesthetist's fee isn't a single number — it's units × dollars.

Every anaesthetic in Australia is billed under the Relative Value Guide. Four ingredients, multiplied by a per-unit dollar value.

Base units

Set by the MBS for each operation — reflects its inherent complexity.

Time units

One unit per 15 minutes for the first 2 hours, then one per 10 minutes after.

ASA modifier

Sicker patients add units (ASA 3 +1, ASA 4 +2, ASA 5 +3).

Other modifiers

Age (under 4 or 75+), emergency, after-hours, additional monitoring.

The five different “unit values” patients see fragments of on their statements:

Reference unit2025–26 valueWho sets it
MBS schedule fee (1 basic unit)$23.10Australian Government
Medicare rebate (75% of MBS)$17.35 / unit
AMA recommended fee~$110 / unitAustralian Medical Association
Fund no-gap scheme rate$36–$45 / unitEach health fund
Typical anaesthetist charge$55–$80 / unitEach individual anaesthetist

The “gap” is the space between the fourth and fifth rows — what an anaesthetist charges minus what their fund pays. Your fund's scheme is what closes it.

03The 75/25 Rule

Medicare pays 75%. Your fund pays 25%. Everything else is the gap.

Medicare pays 75% of the MBS schedule fee; your fund must pay at least the other 25%. Combined that's 100% of the MBS fee — but not 100% of what the anaesthetist charges. Here's a worked example where the MBS fee is $400, the fund's no-gap threshold is $700, and the known-gap ceiling is $1,200.

Anaesthetist chargesMedicare + fund paysFund top-upYou payScheme
$400$400$0At MBS
$650$400$250$0No-gap
$800$400$300$100Known-gap
$1,200$400$300$500Known-gap (cap)
$1,300$400$0$900No scheme — full gap

The last row is the cliff. At $1,201 the fund drops back to its 25% minimum and the gap balloons by hundreds — not by $1.

The known-gap cap doesn't soften the edge — it creates it. Once your anaesthetist charges $1 above the threshold, the scheme exits entirely.
04The Estimator

Estimate your anaesthetist gap before you say yes.

Pick your state, fund, procedure and the anaesthetist's 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 the same 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.

iii.

What to do next

Call your anaesthetist's rooms for a written estimate, and ask if they use your fund's scheme.

05Your Fund's Role

Every fund has its own gap scheme — the differences are real, but smaller than you'd think.

All major funds run two tiers: no-gap up to a threshold, known-gap up to $500 above it. The per-unit values differ — but the bigger factor is whether your anaesthetist participates at all.

HBF (WA)

Specialist Anaesthetist Schedule
$41.45 /unit

Highest rate, WA members only. No-gap scheme.

NIB GapSure

Anaesthetic-specific
$45.00 /unit

Flat rate. Mandatory no-gap for procedures under 5 base units.

AHSA funds

Per-unit values current at 1 November 2025 indexation. Most funds sit within a $1–$3 band. Even an anaesthetist listed in your fund's directory can choose not to use the scheme for your procedure — so the phone call to their rooms is worth more than any directory.

06Geography

Your postcode predicts your gap better than your fund does.

In Tasmania, about 1 in 12 anaesthetic services attracts a gap. In the ACT, it's nearly 1 in 2.

07Your Invoice, Decoded

Why your anaesthetic bill has multiple line items.

An anaesthetist bills a separate item for each major part of the case. Here's what each one is.

i. The pre-anaesthesia consultation (items 17610–17625) — your pre-op assessment, billed by duration. Each has its own EMSN cap when performed out-of-hospital:

ItemDurationSchedule feeMedicare 75%EMSN cap
17610≤15 min$50.95$38.25$152.85
1761516–30 min$101.30$76.00$303.90
1762031–45 min$140.35$105.30$421.05
17625>45 min$178.70$134.05$500.00

Schedule fees current at 1 July 2025. EMSN caps apply only to out-of-hospital consultations.

ii. The surgical anaesthesia item — each operation maps to an MBS item with its own base unit count: knee arthroscopy 4 · cataract 5 · total knee replacement 7 · caesarean section 12 · heart bypass 20.

iii. Time units (per §02), iv. ASA physical-status modifiers (items 25000 / 25005 / 25010), v. age and emergency loadings, and vi. therapeutic add-ons (arterial line, nerve blocks, intra-operative echo) each appear as separate line items.

On a complex case, a single anaesthetic invoice can run to 10 or more line items — each one a defined MBS item you can check against the schedule.
08Your Scenario

Four ways you could be admitted — and what each one costs.

i.

Public patient, public hospital

No anaesthetist bill. Medicare and the state hospital cover it through bilateral funding; the anaesthetist is paid by salary or VMO contract.

You pay $0 for medical fees
ii.

Private patient, private hospital

The standard scenario this guide assumes. The 75/25 rule applies and your fund's gap scheme decides what you pay.

$0 to $500, usually
iii.

Private patient, public hospital

You elect to use private cover in a public facility — choice of doctor, anaesthetist bills separately, same gap mechanics.

Possible gap
iv.

Uninsured (self-funded)

Medicare pays 75% of MBS, no fund top-up, and no $500 cap. You pay everything above the rebate.

Often $1,000+
09Other Payers

Not on Medicare? The other ways anaesthesia gets paid.

WorkCover

State worker's compensation. Set fee schedules differ by state. No patient gap.

DVA

Gold or White Card holders. Uses MBS plus a DVA loading. No patient gap.

TAC (Victoria)

Motor-accident-related care. TAC pays in full. No patient gap.

ADF

Serving Defence members are covered through Defence arrangements.

If your anaesthetic falls under one of these schemes, the rest of this guide doesn't apply to you — the payer covers the full bill on a defined fee schedule.

10Your Rights

Informed Financial Consent — what you're entitled to know, before you sign.

You have a right to a written estimate of fees and likely out-of-pocket cost before surgery — with the chance to query or refuse.

Medical Board Code of Conduct

Section 4.5 requires every AHPRA-registered doctor to inform you of fees in a timely manner. It's enforceable — breach can lead to disciplinary action up to deregistration.

Gap Cover Schemes Act 2000

Where a known-gap arrangement is used, the anaesthetist is legally obliged to provide a written estimate and seek your written acknowledgement.

ASA Position Statement PS04

The profession's gold standard: a written estimate of fees and likely out-of-pocket, given before the day of surgery, with your written acceptance.

What good Informed Financial Consent includes

  • The MBS item numbers that apply, and the Medicare rebate amount
  • The anaesthetist's fee for each item
  • Your expected out-of-pocket cost (a range is acceptable)
  • A note on hospital and surgeon costs, or where to find them
  • A recommendation to verify with your private health fund
  • Delivered in writing, in advance — ideally at least two business days before the procedure
If a substitute anaesthetist replaces yours on the day, they should generally charge the fee you were originally quoted unless they've disclosed otherwise in advance.
11The Safety Net Myth

The Medicare Safety Net — often misunderstood, rarely useful here.

The Extended Medicare Safety Net (EMSN) pays 80% of out-of-pocket costs above an annual threshold once you cross it — $861.20 (concessional) or $2,699.10 (everyone else) in 2026, resetting each 1 January.

But most in-hospital anaesthesia doesn't count toward it. EMSN applies only to out-of-hospital services. Once you're admitted to hospital, the safety net effectively stops at the door — which is why patients who've reached their threshold are still surprised by an anaesthetist gap.

The exception is the pre-anaesthesia consultation, if it's done in the anaesthetist's rooms before admission. Those four items carry EMSN caps: 17610 $152.85 · 17615 $303.90 · 17620 $421.05 · 17625 $500.00.

For most patients the safety net is irrelevant to anaesthetist bills — the structural reason gaps can feel so unfair.
12What Patients Get Wrong

Eight misunderstandings worth correcting before surgery.

“I have cover, so I shouldn't pay anything.”
Cover guarantees only 25% of MBS. The gap above MBS is at the fund and anaesthetist's discretion.
“It should be one bill with the surgeon.”
They run separate businesses. Anaesthetists bill independently.
“I reached the Safety Net — why no help?”
In-hospital anaesthesia isn't EMSN-eligible.
“I paid over $500 — isn't there a cap?”
The cap applies only when the anaesthetist actively uses the scheme.
“My friend on another fund paid less.”
Fund differences are small ($5–$15). Participation is the big swing.
“I'll pay upfront and claim back.”
In no-gap/known-gap the anaesthetist bills the fund directly. Paying upfront can forfeit the benefit.
“Can I shop around for an anaesthetist?”
Limited but possible — ask the surgeon's office about alternatives.
“All anaesthetists charge the same.”
They don't — rates run $45–$95 per unit, set independently by law.
13Your Pre-Op Checklist

Twelve questions worth asking before you say yes.

Take this to your pre-op appointments. Most anaesthetists welcome the conversation. Most patients never ask.

Ask the surgeon's office

  1. What out-of-pocket costs can I expect for the anaesthetist?
  2. Did you choose this anaesthetist for experience or availability?
  3. Do you work with anaesthetists who charge a lower fee?
  4. Could I use a different anaesthetist by moving the date or location?

Ask the anaesthetist's rooms

  1. Do you participate in my fund's gap scheme for this procedure?
  2. What's your per-unit fee, and roughly how many units will my procedure attract?
  3. What will I likely pay after Medicare and fund rebates?
  4. Will you provide written Informed Financial Consent before the procedure?
  5. Are there add-ons I should expect — after-hours, arterial line, nerve blocks?
  6. Will you bill the fund directly, or do I pay and claim back?
  7. Will you personally be the anaesthetist, or might a colleague substitute?
  8. Could you charge a lower unit price, or set up a payment plan?
14If Something Feels Wrong

You've had surgery and the bill is bigger than expected. Here's what to do.

Most billing disputes are misunderstandings, not disputes. Check the invoice line by line — each line should show an MBS item number, units billed, the rebate and the gap. If anything's missing, request an itemised invoice; you're entitled to one. Then work through these steps in order:

  1. Phone the anaesthetist's billing office or practice manager.

    Most practices have discretion on hardship discounts. This resolves the majority of disputes.

  2. Contact your health fund.

    They can confirm whether your anaesthetist was registered with the scheme and may re-process the claim under the gap arrangement.

  3. Commonwealth Ombudsman (Private Health Insurance) — 1300 362 072.

    For disputes about how your fund handled the claim.

  4. AHPRA.

    For complaints about a doctor's conduct, including a failure to provide Informed Financial Consent.

  5. Your state's health complaints commissioner.

    HCCC (NSW), HCC (Vic), OHO (Qld) and equivalents, for other fee disputes.

15Common Questions

Frequently asked questions about Medicare and your anaesthetist.

Fifteen questions patients actually ask — answered without sales-speak.

Does Medicare cover anaesthetist fees in a private hospital?
Partly. As a private inpatient, Medicare pays 75% of the MBS schedule fee for each anaesthesia item, and your private health fund must pay at least the other 25%. Combined, that covers 100% of the MBS schedule fee — but not 100% of what the anaesthetist charges, because anaesthetists generally charge above the MBS rate. The difference is your gap, which is usually covered by the fund's no-gap or known-gap scheme.
What is the Medicare rebate for an anaesthetist?
Medicare rebates 75% of the MBS schedule fee for private inpatient anaesthesia. The MBS schedule unit fee is $23.10 (current from 1 July 2025), so Medicare's rebate is about $17.35 per unit. Your fund pays at least another 25% on top. For out-of-hospital services Medicare pays 85% instead of 75%.
How much do I get back from Medicare for an anaesthetist?
Medicare returns 75% of the MBS schedule fee for the anaesthesia items billed. Because anaesthetic fees are built from units (base + time + modifiers) multiplied by a per-unit rate, the dollar figure depends on the procedure. Medicare's share is calculated on the MBS schedule fee, not on what your anaesthetist actually charged — which is why a rebate can look small next to the full bill.
Can I claim an anaesthetist on Medicare?
Yes. Anaesthesia for an eligible procedure attracts a Medicare rebate. As a private inpatient you claim 75% of the MBS schedule fee from Medicare and the balance through your private health fund. As a public patient in a public hospital there's no separate anaesthetist bill to claim — it's covered by the public system.
Are anaesthetist fees covered by Medicare?
Anaesthetist fees are partly covered by Medicare — 75% of the MBS schedule fee for private inpatients. They're rarely fully covered by Medicare alone, because the MBS rate sits below what most anaesthetists charge. Full coverage of the anaesthetist's actual fee usually depends on your private health fund's gap scheme.
Does Medicare cover anaesthesia in a public hospital?
If you're treated as a public patient in a public hospital, your anaesthesia is covered in full — there's no separate anaesthetist bill and no out-of-pocket cost for medical fees. If you elect to be treated as a private patient in a public hospital, the standard private billing applies and you may face an anaesthetist gap.
What's the difference between no-gap and known-gap?
Under a no-gap arrangement the anaesthetist accepts the fund's scheduled rate as full payment and you pay nothing extra. Under a known-gap arrangement the anaesthetist charges above the fund's rate, but your out-of-pocket is capped — typically at $500 per doctor — and must be disclosed to you in writing before the procedure.
Is the $500 gap cap guaranteed?
No. The $500 cap applies only when your anaesthetist actively uses the fund's known-gap scheme. If they don't participate, or if their fee exceeds the known-gap ceiling, the fund reverts to paying only its mandatory 25% of MBS and the cap no longer applies — so the gap can be much larger. This is why confirming scheme participation before surgery matters more than any other single question.
Why is my friend's anaesthetist bill so different from mine?
Funds pay slightly different per-unit rates, but the differences are small — usually $5 to $15 for the same procedure. The big swing is between participating and non-participating anaesthetists. If your friend's anaesthetist used the fund's gap scheme and yours didn't, your friend may have paid nothing while you paid hundreds. Two anaesthetists at the same hospital can produce very different bills.
Can I negotiate the anaesthetist's fee?
Sometimes. Anaesthetists set their own per-unit fees and have discretion, especially in cases of genuine financial hardship. The more reliable path is to ask, before surgery, whether your anaesthetist will bill using your fund's gap scheme — or to ask the surgeon's office whether a participating anaesthetist is available.
Can I choose my own anaesthetist?
You can ask. Surgeons usually work with several anaesthetists and can often accommodate a request with enough notice. Even when an anaesthetist is rostered by the hospital, you can request a substitution for a clinical or financial reason. Don't assume the choice is closed — ask the surgeon's office.
What if my surgery was an emergency?
For genuine emergencies, patient safety comes first and there may be no opportunity to discuss fees beforehand — Informed Financial Consent is then provided as soon as practical after the procedure. The same billing rules apply: 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 items can carry loadings that increase the fee.
Why is the anaesthetic fee for a caesarean section so expensive?
Caesarean section anaesthesia (MBS item 20850) carries 12 base units, against 4 for a knee arthroscopy or 5 for cataract surgery. The higher base-unit count reflects the clinical complexity and the heightened vigilance required when caring for both mother and baby, so the fee starts higher before any time or modifier units are added.
What happens if my anaesthetist isn't in my fund's scheme?
Your fund pays only the legally required 25% of the MBS rate — much less than under a gap scheme — and the $500 cap does not apply. You can be billed the full balance directly, which on a routine procedure can be $1,000 or more. This is why confirming scheme participation in advance matters more than any other detail.
Does my hospital excess cover the anaesthetist's bill?
No. A hospital excess is a fixed amount you pay once per admission to your hospital cover, in exchange for a lower premium. The anaesthetist's gap is a separate medical bill paid through your medical cover. The two are unrelated, and every doctor involved in your care can charge a gap independently.
