How much an adult autism diagnosis costs in Australia

Why there is no single price

Clinicians in Australia set their own fees, and there is no government-published standard price for an adult autism assessment. Costs differ between states, between solo psychologists and multidisciplinary services, and depending on how much testing is involved. Instead of quoting figures that may be wrong for your area, this guide explains what drives the price and how Medicare fits in.

What affects the fee

Medicare: what applies to adults

Public funding can lower the cost for some people. Medicare has items designed for diagnosing and planning treatment for complex neurodevelopmental disorders such as autism, but they are limited to people under 25. If you are 25 or older, those items do not apply to you.

• Under 25: ask your GP whether a referral under these items is appropriate, which can reduce costs considerably.
• 25 and over: a psychiatrist consultation on referral attracts the usual specialist rebate, but gap fees can be significant. Private psychologist assessments are usually paid in full.
• Mental health treatment plans subsidize therapy sessions for mental health conditions; they are not designed to fund an autism assessment.

Can you get an autism diagnosis in Australia for free?

For adults, free assessments are possible but uncommon. Options to ask about include public mental health services, which sometimes assess autism when it is relevant to care you are already receiving; public hospital or university clinics, where available; and research studies that include an assessment. Your GP is the best person to ask what exists locally.

Private health insurance extras policies may contribute toward some psychology services. Cover varies by fund and policy, so ask your fund whether an assessment is included and how much you can claim.

If you are 24 or younger, timing can matter. Because the Medicare items apply only under 25, it is worth raising autism with your GP sooner rather than later, so that any eligible assessment and plan can happen while you still qualify.

Questions for your health fund

• Does my extras policy include psychology, and is a diagnostic assessment claimable or only therapy sessions?
• What is the annual limit, and what is the benefit per session?
• Does the psychologist need a particular registration type for me to claim?
• Are there waiting periods that apply to new policies or upgrades?

Get the answers before your first appointment. Some people discover only afterward that their policy pays for treatment sessions but not assessments, or that a waiting period has not yet passed.

How to get a clear quote

1. Ask for the total estimated fee in writing, not just an hourly rate.
2. Ask what is included: intake, interviews, informant interview, questionnaires, observation, scoring, report, feedback.
3. Ask whether ADHD or other conditions are assessed and whether that changes the price.
4. Ask what Medicare rebate, if any, applies to you, and what the out-of-pocket gap will be.
5. Ask about deposits, cancellation fees and payment plans.
6. Ask whether the assessment follows the National Guideline for the Assessment and Diagnosis of Autism in Australia.

If the fee is a stretch, ask whether the clinician offers a staged approach: an initial consultation first, after which you decide whether to continue to the full assessment. This can avoid paying for a complete assessment before you know whether the clinician is a good fit for you.

Hidden costs to plan for

• Time away from work for appointments.
• Travel, especially in regional and remote areas.
• Follow-up sessions after the diagnosis, which may cost extra.
• Separate assessments if ADHD or learning differences are later suspected.
