Getting tested for ADHD or autism as an adult: cost, insurance and online options by country

It helps to know what a proper assessment includes before comparing prices. Most adult ADHD assessments include a detailed history of childhood, school, work, relationships and health, one or more rating scales, and where possible a second view from someone who knew you when you were young. The clinician checks the diagnostic criteria and looks for other explanations such as anxiety, low mood, sleep problems, substance use or physical health conditions. Autism assessments for adults are usually longer and often involve more than one professional, with developmental history and structured observation or interview.

Price differences often come down to how much of that is included. A short appointment that ends in a result is not the same as a multi-hour assessment with a written report. Before booking anywhere, ask who makes the diagnostic decision, how they are registered, how long the assessment takes, what the written report covers, whether follow-up is included, and whether your local doctor will accept the result for ongoing care.

Adult ADHD can be assessed by psychiatrists, psychologists, psychiatric nurse practitioners and some primary care clinicians. The CDC and NIMH both suggest starting with a healthcare provider, and many adults begin with their primary care provider, who may assess them directly or refer them on. Adult autism evaluations are usually done by psychologists, neuropsychologists or psychiatrists with adult autism experience, and specialist availability varies a lot by state.

Cost depends mainly on your insurance. Ask your insurer whether an ADHD or autism evaluation is covered, whether psychological or neuropsychological testing needs prior authorization, and what you would pay in network compared with out of network. Ask the clinic for a written estimate that lists the appointment and any testing separately. Some clinics are self-pay only and give you paperwork to claim out-of-network benefits yourself.

Telehealth assessment is widely available. The temporary federal rules that let clinicians prescribe controlled medicines, including most ADHD stimulants, by telehealth without an in-person visit were extended through 31 December 2026. If you are relying on a telehealth service for ongoing care, ask what happens if those rules change.

On the NHS, adult ADHD and autism assessment starts with your GP, who can refer you to a specialist service. NICE guidance recommends that adult ADHD is assessed by a specialist and that adult autism assessment is carried out by a team with the right expertise. NHS assessment is free at the point of use, but waits for adult services are long in many areas.

In England, the NHS Choice Framework gives you a legal right to choose which provider you are referred to for a first outpatient appointment, including for mental health, with some exceptions. People often call this Right to Choose. It can let your GP refer you to another NHS-contracted provider with a shorter wait. It applies in England only, and your GP needs to agree the referral is clinically appropriate. Scotland, Wales and Northern Ireland have their own arrangements.

Private assessments are paid for yourself unless you have private medical insurance that covers them. If you go private, check whether your GP will agree to shared care for any medication before you book, because not every practice does.

In Canada, a family doctor can assess and treat adult ADHD, and psychiatrists can assess with a referral. Both are covered by your provincial or territorial health plan. Psychologists can also assess and diagnose ADHD, but they cannot prescribe, and their fees are not covered by provincial plans. Workplace or private extended health benefits sometimes cover part of a psychologist's fee, so check your plan's limit for psychological services before booking.

Adult autism assessment varies even more by province and territory. The federal Framework for Autism in Canada notes that each jurisdiction runs its own approach to diagnosis and support, so look for your provincial health ministry's information first. Publicly funded adult autism assessment is limited in many areas, and many adults use a private psychologist.

Most adults start with a GP. A GP referral lets you claim a Medicare rebate for a private psychiatrist, though gap fees are common, so ask what you will pay out of pocket. Psychologists can assess adults too, usually privately.

Who can diagnose ADHD is changing state by state, and this was last checked in November 2026. In Queensland, specialist GPs have been able to diagnose adult ADHD and start, adjust and continue stimulant medicines since 1 December 2025. In New South Wales, a staged reform lets trained GPs continue ADHD prescriptions and, from late 2026, lets trained endorsed GPs assess and diagnose ADHD. Other states and territories are at different stages, so check your state health department's current page.

For autism, Autism CRC publishes information for adults based on Australia's national guideline for autism assessment, including what a good assessment should involve. Access and funding vary by state, territory and provider.

From 1 February 2026, GPs and nurse practitioners in New Zealand can start medical treatment for adults with ADHD, which used to need a psychiatrist or paediatrician. This widens who can be involved in diagnosis and treatment, though not every practice offers ADHD assessment, so ask your GP what they provide. The Ministry of Health's clinical principles framework describes what a comprehensive ADHD assessment should include, such as developmental history and how the difficulties affect daily life.

Public adult autism assessment depends on need and local service criteria. Health New Zealand's adult autism page explains the routes. Many adults pay privately for a psychologist or psychiatrist.

Under the HSE National Clinical Programme for ADHD in Adults, your GP refers you to your local adult mental health team, which screens the referral before passing it on to an adult ADHD clinic. The service is free, but demand is high and waits can be long. Many adults also use private psychiatrists or psychologists.

For autism, the HSE explains how adults can ask about assessment and what support is available while waiting. Adult autism pathways in Ireland are still developing, so check the current HSE page for your area.

In every country on this page, legitimate clinicians now offer assessments by video. A video assessment can be thorough. What matters is who is doing it and how. Check that the clinician is registered with the relevant professional body in your country, that the assessment includes developmental history and a look at other explanations, and that there is follow-up after the result. Be wary of any service that promises a result in minutes, guarantees an outcome, or ties the assessment price to buying medication.

Keep a free screener in its place. A screener such as the ASRS-6 tells you whether the patterns it asks about are frequent enough to raise with a professional. It does not replace an assessment, and a good assessment service will not treat it as one.

Write down concrete examples of the difficulties you notice at work, at home and in relationships, and how long they have been there. If you can, ask someone who knew you as a child what they remember. Find out what your insurance, public health plan or benefits cover. Ask the clinic for the total cost in writing, including any report. Ask whether your regular doctor will accept the result for ongoing care. If you are on a public waiting list, you can usually stay on it while you think about other options.
