Somebody told you to "get tested." Nobody told you that the phrase covers three different appointments at three different prices, and that the cheapest one is usually the one you need first.
The useful distinction is this: an ADHD diagnostic evaluation, a full psychological testing battery, and medication follow-up are three different services, and most adults should begin by asking for the first.¹ Full testing earns its cost when a clinician has to separate ADHD from a learning disorder, cognitive change or another complicated picture. Medication care needs a clinician who can prescribe and keep following you.
Name the decision before you book
| What you are trying to decide | Ask for this | A useful answer should include | Stop before paying if… |
|---|---|---|---|
| "Could this be ADHD?" | Adult ADHD diagnostic evaluation | A clinical interview, childhood history, effects in more than one part of life, and consideration of sleep, mood, substance use and medical causes | A questionnaire score is presented as the diagnosis |
| "Is there also a learning or cognitive problem?" | Psychological or neuropsychological testing consultation | The exact question the tests would answer, hours, billing codes, report and total estimate | The battery is sold as mandatory for every ADHD diagnosis |
| "I may want medication" | Evaluation with prescribing and follow-up | Who prescribes, how refills and side effects are handled, and the complete first-90-day cost | Medication is promised before an evaluation, or nobody owns follow-up |
Your San Diego route depends on how care is paid for
If you are on Medi-Cal, or are not sure what you have
The county's Access and Crisis Line is 1-888-724-7240, and the county describes it as running "24 hours a day, 7 days a week", offering "mental health referrals" among other services, with callers selecting what they need by numerical prompt.²
Two details make this line more useful than most. "Language interpreter services enable the ACL to assist in over 200 languages within seconds" — so a language barrier is not a reason to send someone else to make the call for you.² And the line is explicitly for "family members, friends, or professionals seeking advice and resources" as well as for the person themselves, which means someone else can make the first call on your behalf without pretending to be you.²
Say what you need plainly: "I need an adult ADHD diagnostic evaluation. Which service handles that assessment for someone in my situation, and who is accepting referrals?" A referral line is a door, not a promise of a county ADHD clinic. If it routes you to your health plan instead, note the date, the name and the reason.
If you have commercial insurance or Medi-Cal through a health plan
San Diego is a multi-plan county, so the number that matters is the behavioral-health number on your own card. Ask for "an in-network adult ADHD diagnostic evaluation — not automatically a full testing battery," then ask who can complete the diagnosis, whether prior authorization is required, what your cost is for the evaluation and the follow-up, and whether the plan will arrange an out-of-network appointment at in-network cost if nobody in network can see you.
California's timely-access standard is generally 10 business days for a non-urgent appointment with a non-physician mental-health provider, subject to clinical exceptions and plan type. A directory is not proof that an appointment exists — ask the plan to find you one, and record the call reference number.³ If nobody in-network has an opening →
If you are paying privately
Ask for a written good-faith estimate covering the diagnostic visit, any testing, the report, the feedback meeting and follow-up — before the first appointment, not after it. Compare two complete ADHD evaluation quotes → · What therapy costs in San Diego →
Telehealth can be real care. The five checks still matter.
An online evaluation is not valid merely because it is convenient, and not invalid merely because it is online. Confirm the individual clinician's California licence, what happens beyond a checklist, what written document you receive, who provides follow-up, and the total first-90-day price.
Medication makes the arrangement more fragile. California requires an appropriate examination and a legitimate medical reason for an internet prescription, and the federal controlled-medication telehealth flexibilities are temporary, currently running through December 31, 2026, so this section is reviewed every 90 days.⁴ ⁵ Use the full online-evaluation check →
Make one call before buying a battery
Use this sentence:
"I am looking for an adult ADHD diagnostic evaluation. Before I book, please tell me whether this is an interview or a full testing battery, who completes the diagnosis, what the total price is, what document I receive, and who handles treatment afterwards."
Then bring a one-page record of what is happening now, what you remember from childhood, where the difficulty shows up, and what else might be affecting attention. Prepare that page privately →
Other regional versions of this page exist, because the doors differ by county: Los Angeles → · Orange County → · the Inland Empire → · the East Bay → · San Francisco → · the South Bay → · Sacramento →
Q&A
Do I need neuropsychological testing to be diagnosed with adult ADHD? Usually, no. A qualified clinician can often diagnose ADHD through a thorough clinical evaluation. Testing earns its cost when there is another question the interview cannot answer.¹
Does the Access and Crisis Line diagnose ADHD? No. The county describes it as crisis support and referral, including mental health referrals.² Ask which service is responsible for your evaluation.
I do not speak English well. Can I still call? Yes. The county states that interpreter services let the line assist in over 200 languages within seconds.²
Can someone else call for me? Yes. The county names family members, friends and professionals seeking advice and resources among the people the line serves.²
