How Much Does ADHD Testing Cost in New Jersey?

The short answer

Most adults are diagnosed with ADHD in a psychiatric evaluation, not a day of tests. In Northern New Jersey, which includes Union County and Cranford, Medicare’s 2026 amount for a first psychiatric evaluation with medical services (CPT 90792) is $220.41; with Original Medicare you pay 20%, $44.08, once the $283 Part B deductible is met. Formal psychological or neuropsychological testing is billed by the hour: at the same Medicare rates, an example with a diagnostic interview, two hours of testing and three hours of interpretation and report comes to $709.57, and a private-pay testing practice can charge thousands. Insurers pay for that testing only in some situations; Aetna’s written policy says it is rarely medically necessary for uncomplicated ADHD. For children, a New Jersey school district evaluation costs the family nothing.

Three different things are called “ADHD testing”

Prices online run from free to many thousands of dollars because they describe different services. NIMH explains that diagnosing ADHD in an adult relies on interviews, rating scales or symptom checklists, reports from people who knew you as a child, and a review of mood and medical conditions; adults must have had symptoms before age 12. Psychological tests are one possible part of that picture, not the whole of it.

1. A screening questionnaire. Online checklists and self-report scales take minutes and can be free. They can start a conversation, but they cannot diagnose ADHD on their own.
2. A diagnostic evaluation. An interview with a psychiatrist, psychiatric nurse practitioner, psychologist or other clinician about your symptoms now and in childhood, often with rating scales. This is how most adults are diagnosed, and it is billed like any first psychiatric visit.
3. Psychological or neuropsychological testing. Hours of standardized tests of memory, attention, planning and reasoning, then a written report. It is billed by the hour, which is why it costs several times more, and it answers narrower questions, such as whether a learning disability is involved.

What an ADHD evaluation with a psychiatrist costs

A first psychiatric evaluation is billed either as a psychiatric diagnostic evaluation or as a new-patient office visit. Medicare publishes an amount for each code in each part of the state; the figures below are 2026 amounts for a visit in a doctor’s office, worked out from CMS’s 2026 relative value files (you can check any code in the CMS look-up tool).

Northern New Jersey is Medicare locality 01: Bergen, Essex, Hudson, Hunterdon, Middlesex, Morris, Passaic, Somerset, Sussex, Union and Warren counties. Every other county is in locality 99. Medicare pays a psychiatric nurse practitioner 85% of the physician amount, so the same 90792 evaluation is $187.35 with a nurse practitioner in Northern New Jersey.

Medicare Part B covers psychiatric evaluation and diagnostic tests in outpatient mental health care. You pay the yearly deductible, which CMS set at $283 for 2026, then 20% of the approved amount:

Commercial plans pay their own contracted rates, so the Medicare figures are a public yardstick, not your bill. With a work or Marketplace plan, an evaluation is usually an ordinary specialist mental health visit: you pay the copay, or the plan’s rate until your deductible is met and then coinsurance. What a psychiatrist costs in New Jersey walks through copays, deductibles, follow-up visits and self-pay rules in detail.

What psychological and neuropsychological testing costs

Formal testing is billed by time, in two parts: the hours spent giving and scoring the tests, and the hours spent interpreting them, writing the report and going over it with you. Psychologists bill these codes, and Medicare pays a clinical psychologist the full fee schedule amount.

Here is how the hours add up in one example. It is an illustration, not a typical or quoted battery; the psychologist chooses the tests and hours for your question, and plans check that the hours requested are reasonable.

Private-pay practices that do not bill insurance set their own prices and may include more hours. One Los Angeles testing practice, for example, publishes $5,875 to $7,250 for an evaluation for ADHD or autism, covering a clinical interview, four to six hours of testing, a written report and a feedback session, and gives patients a receipt with billing codes to submit to their insurer. That is a single practice’s price, not a New Jersey average; ask any practice for its own written estimate.

Will insurance pay for formal testing?

Plans decide case by case whether psychological testing is medically necessary, and they publish the rules. Aetna’s Clinical Policy Bulletin 0158 is one written example, and Aetna is among the plans Labyrinth lists:

• Uncomplicated ADHD: neuropsychological or psychological testing is “rarely considered medically necessary.”
• When ADHD versus a learning or language disorder is unclear after history and examination, testing to tell them apart can be medically necessary.
• Neurologically complicated ADHD, such as after a head injury or with seizures, may qualify.
• Testing for school reasons is not covered; the policy notes that school systems usually provide it. Testing for employment, disability qualification or legal purposes is not covered either.
• Active substance use or withdrawal: testing is not considered medically necessary then, because the results may be invalid.
• Hours are checked: the hours requested must not exceed what is reasonably needed to answer the clinical question.

Other insurers have their own policies, so ask yours whether testing needs prior authorization and which codes it covers. With Medicare, diagnostic tests in outpatient mental health care fall under Part B; your share is the deductible and 20%. If you have Aetna, seeing a psychiatrist with Aetna explains which Aetna plans fit and when a referral is needed.

Without insurance: what self-pay costs

If you pay yourself or go out of network, the practice sets the price, and Medicare’s amounts do not limit it. Labyrinth has not published self-pay prices, and this article does not guess at them; call 908-336-1187 to ask. Two federal rules protect you when you pay yourself:

1. A written estimate before the visit. If you are not using insurance and schedule at least 3 business days ahead, the practice must give you a good faith estimate of expected charges.
2. A way to dispute a bill that runs over. If the bill comes in $400 or more above the estimate, you can start a federal dispute. Keep the estimate.

Psychiatric care counts as a medical expense under IRS Publication 502, so HSA or FSA money can usually pay for an evaluation. NJ FamilyCare gives New Jersey residents who qualify free or low-cost coverage that includes mental health care; it is not on the list of plans Labyrinth publishes.

For a child or teen: the school evaluates at no cost

Labyrinth sees adults only. If you are asking for a child, the public school is the place to start. Under federal rules, a parent may request an initial evaluation. In New Jersey, a referral is a written request to the school district, and the child study team, a school psychologist, a learning disabilities teacher-consultant and a school social worker, manages the evaluation. According to the state’s Parental Rights in Special Education booklet:

• Within 20 calendar days of receiving your written request, the district must hold a meeting to decide whether to evaluate.
• The district may not require you to use your private or public insurance for the evaluation; if you do not consent, it must still provide it at no cost to you.
• If you disagree with the district’s evaluation, you can ask for an independent evaluation at public expense, unless the district asks a judge to rule that its own evaluation was appropriate.
• A report from a professional in private practice, completed within the past year, may be used as one of the required assessments.

A school evaluation decides eligibility for special education and related services. It is not a medical diagnosis of ADHD and does not lead to a prescription; for that, the child’s pediatrician or a child psychiatrist is the next step.

Questions to ask before you book

1. Which kind of “testing” is this? An evaluation visit, or hours of psychological testing with a report? The price difference is large.
2. Which codes and how many hours? Testing is billed per hour or half hour. Ask for the codes and the expected hours; your plan can price them.
3. Does my plan need prior authorization? Plans review testing hours before they pay. Ask the plan, not only the practice.
4. Is the clinician in my plan’s network? Some testing practices are private pay and give you a receipt to submit yourself. Out-of-network reimbursement depends on your plan.
5. What does the report include, and when? Some practices charge separately for the written report or the feedback visit.
6. Can I have a written estimate? If you pay yourself and book at least 3 business days ahead, the practice must give you a good faith estimate.

What an adult ADHD evaluation at Labyrinth includes

At Labyrinth, the first adult ADHD evaluation takes one hour with a psychiatrist or psychiatric nurse practitioner in Cranford. The clinician asks how attention, organization and restlessness affect your work, relationships and routines today and what school and home were like when you were young, and reviews mood, anxiety, sleep, alcohol and substance use, medical history and current medications. You hear what the evaluation found and which options fit: medication, therapy or both. There is no single test that diagnoses ADHD, and the practice does not list neuropsychological testing among its services; if your clinician thinks formal testing would answer a question the evaluation cannot, ask about a referral.

Bring a list of every medication and supplement you take, any ADHD or psychiatric medications you have tried, any earlier ADHD testing, psychiatric records or school reports you still have, and your insurance card. Labyrinth lists Aetna, Blue Cross Blue Shield, Cigna, Medicare, TRICARE and UnitedHealthcare / Oxford; that list is not a guarantee of coverage, and the insurance and access page explains what the office checks. Call 908-336-1187, use the evaluation request form, or request an appointment; office staff follow up to arrange a time.
