Anaesthetist income planner

Anaesthetist billings & income calculator

Anaesthetists don't bill flat item fees — they bill units. Every case = (basic units for the procedure + time units + modifier units) × your dollar-per-unit. Build a week of theatre lists, set your case mix and your rate, and choose how much you bill no-gap (accept the fund rate) versus with a gap (your full rate) — then add pain-medicine and obstetric work, public sessions, your low overhead, and see the after-tax take-home.

Indicative only, and general information — not personal financial, tax or billing advice. The MBS anaesthesia unit value indexes every July ($23.70/unit from 1 July 2026); fund no-gap/known-gap rates and what anaesthetists charge vary widely — set your own.

Interactive Australian anaesthetist income planner using the Relative Value Guide (RVG) unit system: each case = basic units (procedure complexity, items 20100-21997) + time units (1 per 15 minutes for the first 2 hours then 1 per 10 minutes) + modifier units (ASA physical status, age, emergency) times a dollar-per-unit; build a week of theatre lists, pain-clinic and public-sessional days; split billings between no-gap (fund rate) and known-gap/private (your full rate); add obstetric and pain income; take off the low billing-service and indemnity overhead; and see the after-tax take-home.

Pain clinic — a typical pain-procedure dayInterventional pain lists bill flat MBS item fees (not RVG units): facet/medial-branch blocks, radiofrequency ablation, epidurals, plus consults.
Procedures / pain-day0
Consults / pain-day0
Pain procedures are billed per item, often per side/level (facet block 39013 $130.60; RF denervation 39110 $320.80/side). Consults use the pain-medicine items (2801/2806) at a private fee above the rebate.
Obstetric & on-call (optional)
Labour epidural is a flat-fee item (18216 $227.30 + $22.75 / 15 min beyond the first hour), often after-hours (items 18226/18227). After-hours emergency anaesthesia adds a 50% loading (item 25025). On-call is usually a retainer + fee-for-service per case.
Public / sessional & salaried (optional)
Public days you tag above are paid at this sessional rate (VMO ≈ $1,100 / 4-hr session ≈ $275/hr; locum ≈ $2,500-$3,500/day). A full-time staff-specialist package is ≈ $300k-$450k. Public income is employment-style — no billing/overhead is taken off it here.
Overhead & adminAnaesthetists have low overhead — no consulting rooms. Mostly a billing-service fee plus medical indemnity.

Your dollar-per-unit and how much you bill no-gap are the two big levers: the MBS rate is only ~$23.70/unit, funds pay ~$32-$40 no-gap, the AMA guide is ~$106 — most anaesthetists charge $55-$80 on gap cases.

How anaesthesia billing works — the 60-second version

Units, not item fees. Anaesthesia uses the Relative Value Guide: fee = (basic units for the procedure, from items 20100-21997 + time units + modifier units) × a dollar value per unit. Time = 1 unit per 15 min for the first 2 hours (max 8), then 1 unit per 10 min. Modifiers add units for ASA physical status (III +1, IV +2, V +3), age (<4 or ≥75 +1) and emergency (+2); after-hours emergency adds a 50% loading.

The $/unit is where the money is. Medicare's schedule is only ~$23.70/unit; the AMA guide is ~$106. Each anaesthetist sets their own rate — most land $55-$80/unit — so almost every private case has a gap the health fund and patient cover. The no-gap (~$35) and gap (~$75) rates in this tool are the total banked per unit — nothing separate to add.

No-gap vs gap. Under a no-gap arrangement you accept the fund's rate (~$32-$40/unit) and the patient pays nothing — about two-thirds of insured cases end up here. On gap cases you charge your full rate and the patient wears the difference. (A known-gap scheme caps that gap at ~$500, but full-rate billers usually bill outside any scheme, uncapped — this tool models your full rate.) Billing more no-gap is patient-friendly but lowers your $/unit — the biggest driver of your income.

Other streams. Many anaesthetists add a chronic-pain practice (flat-fee interventional procedures + consults), obstetric/on-call epidural work (often after-hours), and public sessional or staff-specialist work.

Low overhead, high income. With no consulting rooms, overhead is small — a billing service (~4.5% of billings) and indemnity (~$5k-$15k/yr, low-risk vs proceduralists). That's why anaesthetists are among the highest-earning specialists (ATO average ≈ $447k).
