What does ADHD assessment actually cost in your situation?

United States
US — private insurance (commercial)
Cost: $0–$500 out of pocketWait: 2–8 weeks
Standard pathway for adults with commercial insurance. Cost depends on plan deductible and whether the assessing clinician is in-network. Many insurance plans cover psychiatric assessment but require a referral; some require prior authorization for psychological testing.
Verify behavioral-health benefits
Call your insurance plan and ask: "Are psychiatric assessments and ADHD evaluations covered? Do I need a referral? Is there an in-network provider directory?" Ask about prior authorization specifically.
Choose telehealth or in-person
In-network telehealth options like Talkiatry, Circle Medical, and LifeStance accept most major commercial insurance. In-person clinical psychologists and psychiatrists are also options if you prefer face-to-face.
Initial diagnostic visit
Typically 60–90 minutes. Includes structured interview, rating scales (ASRS, Conners), and a developmental history. Some providers conduct this across two visits.
Diagnosis and initial treatment plan
If ADHD is diagnosed, the clinician discusses treatment options (medication, therapy, lifestyle). First medication trial typically starts at this visit or shortly after.
Titration follow-ups
Monthly visits during initial titration (usually 3–6 months). Quarterly thereafter once stable. Follow-up visits also typically billed to insurance.
United States
US — Medicaid
Cost: $0 out of pocket (in-network)Wait: 4–12+ weeks
Medicaid generally covers ADHD assessment and treatment. The constraint is provider availability — many private psychiatrists do not accept Medicaid, and community mental-health centers often have longer waits. Coverage and rules vary by state.
Find a Medicaid-accepting provider
Use your state Medicaid plan's provider directory or call member services. Federally Qualified Health Centers (FQHCs) accept Medicaid universally and often have ADHD-treating providers.
Book the earliest available appointment
Wait times can be substantial. Some patients ask to be added to cancellation lists. Some psychiatric NPs accept Medicaid where MDs don't.
Initial diagnostic visit
Same structure as the commercial-insurance pathway — interview, scales, history. Typically 60–90 minutes.
Medication and follow-up
Medicaid generally covers ADHD medications, though formulary and prior-authorization rules vary. Generic options are usually preferred.
United States
US — cash-pay / no insurance
Cost: $150–$2,500Wait: 1–4 weeks
Cash-pay options range from low-cost telehealth services ($150–300 initial assessment) to comprehensive neuropsychological evaluation ($1,500–2,500). The trade-off is depth of assessment vs. speed and cost.
Decide between brief and comprehensive assessment
A telehealth ADHD assessment ($150–300) covers structured interview and scales; a comprehensive neuropsychological evaluation ($1,500–2,500) covers cognitive testing, more differentials, and a detailed report. Most adults don't need the latter unless there are diagnostic complexities.
Select a service
Telehealth options vary in prescribing scope, follow-up cadence, and reputation. Some have had regulatory issues — check current state before committing.
Initial visit
Telehealth visits are typically 30–60 minutes. Comprehensive evals are 4–8 hours, usually split across multiple sessions.
Prescription and follow-up
If prescribed, follow-up costs vary ($70–200 per visit cash-pay). Some patients establish ongoing care with a separate provider after diagnosis.
United Kingdom
UK — NHS pathway
Cost: £0Wait: 2–7 years (current published data)
NHS adult ADHD assessment is free at the point of care, but waiting lists in many regions are extremely long — published wait times from various NHS Trusts have reached 5+ years. Pediatric ADHD has shorter waits. Right To Choose (England) allows patients to select an NHS-funded provider with shorter waits.
Visit your GP
Your GP can refer you to the local NHS adult ADHD assessment service. They may complete a screener (e.g., ASRS) first.
Right To Choose (England)
Under the NHS Right To Choose, patients in England can request referral to any NHS-funded provider, including independent sector clinics with shorter waits. This often reduces wait time substantially. Ask your GP specifically about Right To Choose.
Specialist assessment
NHS or NHS-commissioned clinic. Includes structured interview, scales (Conners, DIVA-5), developmental history. Typically thorough.
Diagnosis and shared-care agreement
If diagnosed, the specialist may initiate medication and then transfer prescribing to your GP under a shared-care agreement. Shared-care agreements vary in availability across CCGs.
Private adult ADHD assessment in the UK has grown rapidly due to NHS waiting times. Common providers include Psychiatry-UK, ADHD-360, Ahead, and others. Many patients use private assessment then transition to NHS shared care.
Choose a provider
Several established private services. Costs vary; check current pricing. Verify the service is registered with the CQC and that the assessing clinician is a GMC-registered psychiatrist.
Initial consultation
Typically video-based; 90+ minutes. Includes structured interview, scales, and developmental history.
Diagnosis and titration
If diagnosed, the private psychiatrist may initiate medication. Some patients continue private prescribing; others request shared-care transfer to NHS.
Shared-care transfer (variable)
Some GP practices and CCGs accept shared-care transfer from private providers; others do not. Check with your GP before assuming this is possible.
Canada
Canada — provincial healthcare
Cost: C$0 (covered) to C$2,500 (private)Wait: 3–24 months
Provincial healthcare covers ADHD assessment and treatment, but adult psychiatric access varies dramatically by province. Wait times for publicly-funded adult ADHD assessment can be 1–2 years. Private telehealth options exist for shorter waits.
Family doctor referral
Your family physician refers to a psychiatrist or specialist clinic. In provinces with sparse psychiatric access (notably some rural areas), this can mean very long waits.
Consider private telehealth
Several Canadian private services (Frida Canada, Ahead, others) offer faster access. Provincial coverage of private services varies.
Specialist assessment
Standard structured interview and scales. Some provinces have ADHD-specific clinics; others rely on general psychiatry.
Treatment
Medications are covered under provincial drug benefit programs (varies by province) for those who qualify. Private insurance often covers as well.
Australia
Australia — Medicare + private
Cost: A$200–A$1,500Wait: 6 weeks–18 months
Medicare covers part of the cost of ADHD assessment via psychiatrist referral (Better Access scheme). Total out-of-pocket varies. Wait times to see a psychiatrist for adult ADHD can be lengthy in many areas.
GP visit and Mental Health Treatment Plan
Your GP can complete a Mental Health Treatment Plan and refer to a psychiatrist for assessment. Medicare provides a rebate on the psychiatrist visit.
Psychiatrist assessment
Comprehensive ADHD assessment by a psychiatrist; typically 90+ minutes. Out-of-pocket cost varies — psychiatrists set their own fees above the Medicare rebate.
Telehealth options
Some online psychiatry services (Updoc, Australia-based ADHD clinics) offer faster access. Medicare rebates apply to most legitimate telehealth psychiatry.
Treatment
Stimulants are Schedule 8 controlled substances in Australia and require state-level authority for ongoing prescription. Most prescribing is by psychiatrists, with GP shared care variable by state.
