Our Experience Assessing DIAS
HDAA is proud to have been involved with the Department of Health as an Approved Accreditor for the Diagnostic Imaging Accreditation Scheme (DIAS) since its implementation in 2008. We have supported literally hundreds of diagnostic imaging services with DIAS accreditation over the intervening years, providing a personalised and responsive assessment service and information for individual practices undertaking accreditation and the scheme updates, benefits and changes.
As an experienced provider of diagnostic imaging accreditation services, HDAA has designed a straightforward online system,
What is the DIAS?
DIAS refers to the Diagnostic
The Diagnostic Imaging Accreditation Scheme was established by the Health Insurance Amendment (Diagnostic Imaging Accreditation) Act 2007 to ensure Medicare funding is directed to diagnostic imaging services that are safe, effective and responsive to the needs of health care consumers. The Health Insurance Act 1973 provides the legislative framework for DIAS.
The scope of DIAS includes radiology and non-radiology diagnostic imaging services and provides practices with eligibility to offer Medicare Australia funding for relevant services.
Practices that provide
All practices undergoing accreditation since 1 January 2016 are assessed against the revised standards whether entering the scheme, progressing from Entry Level to Full Suite or undergoing re-accreditation to the Full Suite of Standards.
The Health Insurance Act 1973 (the Act) provides the legislative framework for the introduction and operation of the Diagnostic Imaging Accreditation Scheme for practices providing diagnostic imaging services under Medicare.
The Act allows the Minister for Health to establish through legislative instruments, the rules governing the operation of the Scheme, including the organisations able to provide accreditation services, i.e. HDAA Australia.
More details on the applicable legislation and progress of the DIAS can be accessed from the “Background Information” page of our website.

The Key Features of DIAS accreditation
A new practice (new business or new entrant to the scheme) can choose either the Entry Level or the Full Suite of Standards.

Accreditation to the Full Suite of Standards requires
Services choosing not to become accredited (or who do not achieve accreditation) will not be eligible for Medicare funding. Practices must notify patients before providing diagnostic imaging services if the practice is not accredited and therefore that Medicare benefits are not payable.
