How much does an ADHD diagnosis cost?

The price depends on who makes the diagnosis and how

Every regulated clinician who diagnoses ADHD uses the same DSM-5-TR criteria, so the price differences are about access, time and credentials rather than a different standard of diagnosis. The ranges below are general market estimates; they vary by province, provider and the depth of the written report.

A diagnosis has line items beyond the assessment appointment

The number on a clinic's website is usually the assessment fee. The full cost of getting diagnosed and set up can include more, and the items below are where quotes differ most:

• Intake and screening. Sometimes free, sometimes bundled, occasionally a separate charge.
• The assessment appointment. The core fee; ask whether results are delivered in the same session or at a second one.
• A diagnosis letter. Often included; sufficient for most employers and many schools.
• A full report. More detailed, and sometimes an additional fee; needed for some universities, exam boards and professional bodies.
• Forms. Disability Tax Credit, accommodation and insurance forms are commonly billed separately by every type of provider.
• Follow-up visits. Needed to start and adjust medication, and priced per visit or per package depending on the service.
• Medication and therapy. Always separate: medication is a pharmacy cost, and therapy is billed per session.

Our page on what is included in the price of an ADHD assessment gives the questions to ask before booking so none of these arrives as a surprise.

The public route costs nothing directly, but the wait is the price

If you have a family doctor who is comfortable assessing adult ADHD, a diagnosis can be made in primary care at no charge to you, and that is a perfectly good route. The difficulties are practical: many family doctors refer adult ADHD on to psychiatry, publicly funded psychiatrists have long waits, and millions of Canadians have no family doctor at all. The result is that a free diagnosis is often a slow one, and for someone whose job, studies or relationships are suffering now, the delay has its own cost. Our page on how long it takes to get an ADHD diagnosis in Canada sets out typical timelines by route.

Budgeting for the first year after a diagnosis

A diagnosis is the start of treatment, not the end of spending, so it helps to think in terms of a first year. The assessment is a one-time fee. Follow-up visits cluster in the first few months, when medication is being started and adjusted, and then spread out. Medication is an ongoing monthly pharmacy cost that depends on the drug, the dose, generic versus brand, and whether a private plan or public program covers part of it. Therapy or coaching, if you choose it, is billed per session, and benefits may reimburse some of it. Documentation for school or work is usually a one-time cost when needed. How much ADHD treatment costs per month in Canada breaks down the ongoing part.

There are several ways to pay less for the diagnosis you need

• Check private benefits first. Many plans reimburse psychologist fees, and a growing number reimburse nurse practitioner services; confirm the category and annual maximum.
• Use a health spending account for whatever benefits do not cover.
• Claim the Medical Expense Tax Credit. Fees paid to a regulated practitioner, including physicians, nurse practitioners and psychologists, are generally eligible.
• Students: use both plans. Your student association plan and a parent's plan can often be coordinated.
• Ask about payment plans. Spreading the fee over several months is offered by some services, including Finding Focus.
• Already diagnosed? If you have documentation from a previous diagnosis and need treatment rather than a new assessment, Finding Focus offers a reduced initial consultation.

Finding Focus provides online ADHD assessment and treatment for adults and teens in several Canadian provinces, with no referral needed, from $399. Current fees and what each option includes are on the pricing page.
