Seven practices with Orange County offices publish what an adult ADHD evaluation costs. The lowest is $350 for a first visit with a nurse practitioner who can prescribe. The highest published testing tier is $6,000.
These are different services. A visit-based evaluation diagnoses from an interview, history and rating scales. A testing package adds hours of standardized tests and a long report. Most adults can get an answer from the first.¹ Pay for testing when there is a second question, like a learning disorder, or when a school or exam board requires a full report.
What Orange County practices publish
How a practice is listed: it has an office in Orange County, and its own site publishes a price for an adult ADHD evaluation or an adult evaluation that includes ADHD. Read on November 6, 2026. No one paid or was asked; a listing is not a recommendation. Rows run from lowest published price. Practices that publish only an hourly rate, or no price, are not here.

What the tables show
- One practice takes insurance for the evaluation: IPW Health, and its list is long, including Blue Shield of California and Medicare. Mind Over Matter routes insurance through a third party.
- Every testing practice here is private pay. Expect to claim back what your plan allows out of network.
- Six of the seven are in Newport Beach. Three share one address, 4000 MacArthur Blvd. None of the seven publishes a price at an office in north Orange County.
- Visit-based evaluations here are fast: same week, or 24–48 hours, where published.
Start with your plan
CalOptima Health (Medi-Cal)
Call CalOptima's behavioral health line at 1-855-877-3885 (TTY 711), 24 hours a day. The plan lists getting to "know your mental health needs through an evaluation or assessment" among its behavioral health services.² Ask for an adult ADHD evaluation and whether the clinician can prescribe. For serious conditions, the county's Behavioral Health Plan is 1-800-723-8641.
Kaiser members
Call 1-833-579-4848 (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."³
Commercial insurance
Ask for an in-network adult ADHD diagnostic evaluation, and what you will pay. If no one in network can see you within the timely-access standard, generally 10 business days for a non-urgent mental-health appointment, ask the plan to arrange care.⁴ If nobody in network has an opening →
No insurance, or not sure
OC Links, (855) 625-4657, answers 24/7. The county describes it as a free, confidential service "that connects Orange County residents to mental health and substance use services."⁵ It is a navigation line, not an ADHD clinic.
Students at UC Irvine, Chapman and Cal State Fullerton
- UC Irvine: Student Health says "we will not make a new diagnosis of ADHD in the college years." For a new diagnosis you are referred to a community provider in the SHIP network; Student Health can continue care for ADHD identified in childhood.⁶ The Counseling Center helps find an off-campus assessment provider.⁷
- Chapman: "Does Chapman University offer testing to diagnose learning disorders or ADHD/ADD? No." Students seeking ADHD assessment or ADHD medication "are not eligible to be seen" by its prescribing clinicians.⁸
- Cal State Fullerton: CAPS works with students to find outside providers for "specialized assessment."⁹
Your student insurance is then the plan to call.
Before you pay
"Is this an interview-based diagnosis or a testing package? Who diagnoses, what is the total, what do I get in writing, and who treats me afterwards?"
