You can spend three weeks looking for the right clinic and never discover that the plan you are already on will take a call from you directly, today, with no referral in hand.
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. In San Francisco, the door you start at is unusually well signposted — if you know which of two systems you are in.
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 Francisco route depends on how care is paid for
If you have San Francisco Health Plan Medi-Cal
This is the part most people do not know. San Francisco Health Plan sends mild-to-moderate outpatient mental health care to Carelon Behavioral Health at 1-855-371-8117, and its own member page says plainly: "You do not need a referral to get mental health care."³
So the call is yours to make, today, without a doctor's note first. The plan still suggests talking to your primary care provider, and that is worth doing — but it is a suggestion, not a gate. Open with: "I am an SFHP member and I need an adult ADHD diagnostic evaluation. Which network clinician can complete that, and what is the soonest appointment you can locate?"
One thing to settle in the same call: whether the clinician who evaluates can also prescribe, or whether medication goes back through your primary care provider. That answer decides whether you have one appointment to make or two.
If you are unsure where to start, or have no insurance
San Francisco's Behavioral Health Access line is (415) 255-3737 or toll-free (888) 246-3333, TTY (888) 484-7200, 24/7.² ³ The city describes it as support "finding and connecting with the mental health and/or substance use service that's right for you."²
Ask directly: "I need an adult ADHD diagnostic evaluation. Which service handles that assessment for someone in my situation, and who is accepting referrals?" An access line is a door, not a promise of a city ADHD clinic — and asking plainly is how you find out which it is for you, today, rather than after four weeks of waiting.
If you have commercial insurance
Call the behavioral-health number on the card and 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.⁴ 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. San Francisco has the densest concentration of private assessment practices in Northern California, which means quotes vary more here than almost anywhere, and a quote that covers only "testing" is not a quote.

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.⁵ ⁶ 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 →
Two neighbouring versions of this page exist, because the doors differ by county: the East Bay → · the South Bay →
Q&A
Do I need a referral for mental health care on San Francisco Health Plan? No. The plan's own member page states that you do not need a referral to get mental health care, and routes mild-to-moderate outpatient care through Carelon Behavioral Health at 1-855-371-8117.³
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 city access line diagnose ADHD? No. San Francisco describes the line as help finding and connecting to the right service.² Ask which service is responsible for your evaluation, and who is accepting referrals.
Can a San Francisco clinician evaluate me online? Telehealth can be used for diagnosis when the clinician is properly authorized in California and the evaluation meets the standard of care. Prescribing carries additional state and federal rules.⁵ ⁶
