Australia Reimbursement for AI Echocardiography
Coding and reimbursement pathways in Australia for echocardiography under the Medicare Benefits Schedule (MBS): Group I1 Subgroup 7 items for initial, serial, and stress echo, plus the CSANZ Level 2 requirements for billing stress items.
Reimbursement Landscape in Australia
Echocardiography in Australia is reimbursed through the Medicare Benefits Schedule (MBS), administered by Services Australia under the Department of Health and Aged Care. Echo items sit under Group I1, Subgroup 7. Indication, requester type, and prior study history determine which item is billable.
MBS Group I1, Subgroup 7
Echo items 55126 through 55146 cover initial, serial, paediatric, fetal, and stress transthoracic echocardiography. Item selection depends on whether the study is initial, serial for a defined indication, or stress.
Frequency & Indication Rules
Most TTE items carry a 24-month frequency rule unless a specific clinical indication (heart failure, cardiomyopathy, valvular dysfunction, paediatrics, pericardial disease) allows more frequent serial studies.
CSANZ Level 2 for Stress
Stress echocardiography items (55141, 55143, 55145, 55146) require the reporting specialist to hold CSANZ Level 2 (or equivalent) certification in stress echocardiography.
Relevant Coding
MBS items in Group I1 Subgroup 7 covering echocardiography in Australia.
Initial TTE
Real-time TTE with colour flow Doppler, at least three acoustic windows. Once per 24 months unless a serial indication applies.
Scheduled fee: AUD $264.90 (effective 1 July 2025). Any practitioner can request 55126, which makes it the workhorse for new-presentation echocardiograms. AI-assisted measurement and reporting augments the specialist interpretation within this item.
Serial TTE for Valvular Disease
55127 serial TTE for known valvular dysfunction with full quantitative assessment. 55128 same indication when requested by a rural GP in an MMM 3 to 7 area.
Scheduled fee: AUD $264.90 each (effective 1 July 2025). 55127 requires a specialist requester; 55128 extends access for rural / remote GPs (Modified Monash Model 3 to 7) to support rural cardiology pathways.
Serial TTE for Heart Failure, Paediatrics, Pericardial
55129 serial TTE for heart failure or cardiomyopathy. 55132 serial TTE in patients under 17 years or with complex congenital heart disease. 55133 frequent-repetition TTE for pericardial conditions or PBS medication monitoring.
Scheduled fees (1 July 2025): 55129 and 55132 at AUD $264.90; 55133 at AUD $238.40. These items recognise clinical scenarios where the 24-month frequency rule on 55126 is inappropriate. Serial heart failure echocardiography is a particularly high-volume use case for AI-assisted EF and strain quantification.
Rare Repeat and Fetal Echocardiography
55134 repeat TTE for rare cardiac pathologies, once per 24 months. 55137 fetal echocardiography for suspected congenital abnormality.
Scheduled fee: AUD $264.90 each (effective 1 July 2025). Both items require a specialist requester. Fetal echocardiography sits within obstetric / maternal-fetal medicine referral pathways.
Stress Echocardiography
55141 exercise stress echo with ECG. 55145 new pharmacologic stress echo. 55143 repeat pharmacologic stress echo. 55146 additional pharmacologic stress echo (governed by EMSR).
Scheduled fees (1 July 2025): 55141 exercise stress and 55143 repeat pharmacologic stress at AUD $472.20; 55145 new pharmacologic stress and 55146 additional pharmacologic stress at AUD $547.30. All stress items require the reporting specialist to hold CSANZ Level 2 certification in stress echocardiography (or recognised equivalent). AI-assisted strain and EF support pre- and peak-stress interpretation.
Scheduled fees shown reflect the 1 July 2025 MBS indexation. Medicare benefit payable is 75 percent in-hospital, 85 percent out-of-hospital, and 95 percent under bulk-billing arrangements. The Extended Medicare Safety Net (EMSN) may apply for out-of-pocket totals once thresholds are reached. Private health insurance may pay above MBS for in-hospital studies depending on policy. Verify against the live MBS Online schedule and current Department of Health and Aged Care advice.

Reimbursement by Care Setting
MBS items pay differently across out-of-hospital, in-hospital private, and public hospital settings; private health insurance adds a fourth pathway.
Out-of-Hospital MBS
Bulk-billed and direct-billed studies in community cardiology clinics. Medicare pays 85 percent of the MBS scheduled fee, or 100 percent under bulk-billing.
Community cardiology and rural cardiology pathways (55128 in particular) are a strong fit for AI-assisted reporting to lift throughput and reduce report turnaround.
In-Hospital (Private)
Studies performed on an admitted private patient. Medicare pays 75 percent of the MBS fee; private health insurance covers the gap up to its agreed schedule.
Private hospital cardiology services often hold purchaser-provider agreements with insurers that fix gap or no-gap arrangements above MBS.
Public Hospital
Public hospital cardiology services are funded by state and territory governments (Activity Based Funding) rather than MBS per study.
AI-assisted echo in this setting supports throughput within the public funding envelope rather than incremental per-study payment.
Australian Procurement & Regulatory Context
AI echocardiography software is assessed against TGA registration and Australian privacy requirements alongside the clinical and financial case.
TGA Registration
Software classified as a medical device requires inclusion on the Australian Register of Therapeutic Goods (ARTG). Us2.ai is registered as a Class IIb medical device under ARTG entry 382110.
Australian Privacy Principles
The Privacy Act 1988 and Australian Privacy Principles (APP) govern patient data handling. In-country (Australian Sovereign) cloud hosting is available for Australian customers when required by state or hospital policy.
State Health Procurement
State and territory Local Health Districts (LHD / HHS) run their own digital health procurement pathways. ISO 27001 certification and existing state health framework agreements support faster procurement.
