How Much Does an ADHD Assessment Cost?
Total ADHD assessment costs in Australia average close to $1,400 nationally. What drives that figure is the number of sessions, which type of clinician you see, and how much Medicare rebates.
Total ADHD assessment costs in Australia average close to $1,400 nationally, and can run past $4,000 for some people, according to 2026 University of Wollongong reporting. What drives that figure is less about any single fee and more about three things: how many sessions the assessment takes, which type of clinician you see, and how much of it Medicare rebates.
Number of sessions
A full ADHD assessment is rarely one appointment. It usually starts with a standard GP consultation, rebated in full under Medicare item 23 ($45.05 for a 6 to 20 minute visit), then moves into the diagnostic sessions themselves, sometimes split across more than one visit given the clinical interview alone can run two to three hours. Some assessments add a separate follow-up for the written report. Each session adds to the total, which is why the national average sits closer to $1,400 for the whole process. One session, rarely. Three or four, closer to the norm.
Which clinician you see
Provider type changes what Medicare will rebate. For a patient under 25, a psychologist session of at least 50 minutes that contributes to an ADHD diagnosis is rebated 85 percent under item 82000, $101.55 on a $119.45 fee, capped at 8 services across the item group in a lifetime and reviewed after the first 4. A psychiatrist attendance longer than 45 minutes, with a GP referral, is rebated 85 percent under item 291 ($467.45 on $549.90) when it includes a 12-month management plan, or under item 296 ($268.90 on $316.30) as a first referred attendance without that. Once you're over 25, or the item 82000 cap is used up, most psychologist-led assessment sessions are billed privately.
Medication is a separate, ongoing cost
If the assessment leads to a prescription, PBS medicine costs sit on top of the assessment itself: a general patient pays up to $25.00 per prescription from 1 January 2026, or $7.70 with a concession card, a rate frozen until 2029. Once your PBS spending for the year passes a safety net threshold, $1,748.20 for general patients or $277.20 for concession card holders in 2026, the cost per script drops further.
Comparing the full picture
The number that matters most for planning is the total across every session in the process, and the full breakdown of cost and wait time by pathway, psychologist versus psychiatrist versus paediatrician, sits on its own page for anyone comparing options directly.
Common questions
Does Medicare cover the full cost of an ADHD assessment?
No single Medicare item covers a full ADHD assessment end to end. Item 82000 rebates 85 percent of an eligible psychologist session for patients under 25, and items 291 and 296 rebate 85 percent of a GP-referred psychiatrist attendance at any age, but sessions outside those criteria are usually billed privately.
Is ADHD medication expensive once I have a diagnosis?
PBS-subsidised ADHD medication costs a general patient up to $25.00 per prescription from 1 January 2026, or $7.70 with a concession card. Costs drop further once you pass the annual PBS safety net threshold, $1,748.20 for general patients or $277.20 for concession card holders in 2026.
