Twelve practices with offices in Los Angeles County publish what they charge to evaluate an adult for ADHD. The cheapest first visit is under $400. The most expensive testing package is $7,250.
That gap is not one service at two prices. Under $400 buys a psychiatric visit with someone who can prescribe. $7,250 buys a full psychological testing package with a written report. For most adults, the question "do I have ADHD?" can be answered by the first kind.¹ Pay for testing when another question needs answering too, such as a learning disorder or memory change, or when a school or licensing board asks for a full report.
What Los Angeles County practices publish
The rule for being listed: an office in Los Angeles County, and a price for an adult ADHD evaluation on the practice's own website. We read each page on November 6, 2026. No practice paid or was asked to appear, and a listing is not a recommendation. Rows are in order of the lowest published price. Many more practices in the county offer adult ADHD assessment without publishing a price; they are not here.

What the tables show
- Three of the twelve publish an insurance contract that covers the evaluation: Flanigan-Landeros, Thrive & Feel and LA Integrative Psychiatry. Aetna is at all three.
- One takes Blue Shield of California (Flanigan-Landeros). One takes Medicare (LA Integrative). None takes Medi-Cal. If you are on Medi-Cal, start with your plan, below.
- The practices cluster in two places. Five are on the Westside or in Santa Monica, and four are in Pasadena. The other three are in Beverly Hills, Burbank and Hermosa Beach.
- Four publish a wait or a waitlist, ranging from one to two weeks (LA Integrative) to an intake in three to four weeks (Huntington).
If you have coverage, call your plan first
L.A. Care Medi-Cal
L.A. Care says: "You do not need a referral for your first mental health assessment with an L.A. Care contracted provider." Call Carelon Behavioral Health at (877) 344-2858, TTY (800) 735-2929.² Ask for an adult ADHD diagnostic evaluation, and ask whether the same clinician can prescribe.
If your card says Anthem Blue Cross, you may still be under L.A. Care: Anthem says it is "contracted with L.A. Care Health Plan to provide Medi-Cal Managed Care services in Los Angeles County." Anthem's Los Angeles County line is 1-888-285-7801 (TTY 711), weekdays 7 a.m. to 7 p.m.³
Health Net Medi-Cal
Health Net's Medi-Cal handbook says you can get a mental health assessment "at any time from a licensed mental health provider in the Health Net network without a referral," and lists psychological testing "when clinically indicated."⁴ Call Member Services at 1-800-675-6110 (TTY 711), 24/7, and choose the Behavioral Health option. Health Net's own flyer warns that routine psychiatrist appointments "may take up to 15 business days."⁵
Kaiser members
Call 1-833-579-4848 (1-833-KP-WITH-U, TTY 711), weekdays 8 a.m. to 5 p.m. Kaiser Southern California says: "You don't need a referral from a Kaiser Permanente provider to access these services."⁶
Commercial insurance
Call the behavioral-health number on your card. Ask for an in-network adult ADHD diagnostic evaluation, and say you do not want a testing battery unless a clinician says you need one. Ask what you will pay. If the plan cannot find anyone in network within its timely-access standard, generally 10 business days for a non-urgent mental-health appointment, ask it to arrange care.⁷ If nobody in network has an opening →
No insurance, or not sure
The Los Angeles County Department of Mental Health Help Line is (800) 854-7771, 24/7.⁸ The county describes it as mental health "support, resources and referrals"; it is not an ADHD clinic. If you are paying yourself, the lowest published testing price above is $1,000.
Students at UCLA and USC
- UCLA: CAPS does ADHD assessments only "for students with SHIP insurance," over 3 to 4 sessions, and SHIP students must already be in treatment at CAPS or with an outside therapist. Students on other insurance are referred to their own network. An outside diagnosis is accepted for CAPS medication care if it includes "an objective measure such as the CPT or the IVA."⁹
- USC: Student Health prescribes ADHD medication with records from your evaluator. Its policy says: "Medical records are required. Summary letters are not acceptable."¹⁰ Ask any private evaluator for the full report before you pay, not a letter.
One question that sorts every quote
"Is this an interview-based diagnosis or a full testing package? Who makes the diagnosis, what will I pay in total, what will I get in writing, and who treats me afterwards?"
If you might want medication, ask who prescribes and what the follow-up visits cost. Online prescribing of ADHD medication works under temporary federal rules that run through December 31, 2026.¹¹ Check an online evaluation → · Compare two full quotes → · Prepare a one-page history →

Q&A
How much does an adult ADHD evaluation cost in Los Angeles? On November 6, 2026, LA County practices published first psychiatric visits from $389 to $400 (or $600 bundled at Evolve Psychiatry), and psychological testing from $1,000 to $7,250.
Which Los Angeles ADHD testing practices take insurance? Of twelve that publish a price, three name in-network insurers for the evaluation: Dr. Flanigan-Landeros (Optum, Blue Shield of California, Aetna, Carelon), Thrive & Feel Psychology (Aetna) and LA Integrative Psychiatry (Anthem, Aetna, Cigna, UnitedHealthcare, Medicare).
Can I get an ADHD evaluation on L.A. Care without a referral? Yes, for the first assessment. L.A. Care says no referral is needed for a first mental health assessment with a contracted provider. Call Carelon at (877) 344-2858.²
Do I need full testing to be diagnosed with ADHD as an adult? Usually not. A careful interview and history are often enough. Testing is worth its cost when an interview cannot answer another question.¹
