Therapy on Medi-Cal costs you $0. There is no copay, no deductible and no session fee. What there is instead is a fork: California splits Medi-Cal mental health between your managed care plan and the county, and which one you belong in is decided by a written rule rather than by whoever picks up the phone.
Here is the San Mateo County version of both doors, with the numbers and the words to use.
Your plan, in San Mateo County
San Mateo County runs on the County Organized Health System model — one public plan covers Medi-Cal members here, so there is no plan to choose between and no wrong card to hold. The only Medi-Cal managed care plan operating here is Health Plan of San Mateo.¹
About Kaiser. Kaiser Permanente holds a direct Medi-Cal contract in San Mateo County, but enrolment in it is restricted — broadly, you qualify if you were a Kaiser member in the last 12 months, have a family link to a current member, are a foster or former foster youth, or are enrolled in both Medi-Cal and Medicare.¹ It is not an open choice for a new Medi-Cal member, whatever you may read elsewhere.
If you do not know which plan you have, the card says so. If you have no card, Health Care Options — the state's Medi-Cal enrolment line — is (800) 430-4263, and the general Medi-Cal helpline is (800) 541-5555.¹
Door one: your plan — everyday therapy
Anxiety, depression, grief, stress, a hard year: that is the non-specialty lane, and it belongs to your managed care plan. Call the behavioural health or member services number on your card and say:
"I am requesting outpatient therapy. Please give me therapists taking new patients, and an appointment within 10 business days, per the timely access standard."
That deadline is real. A non-urgent appointment with a non-physician mental health provider must be offered within 10 business days of your request, and if the plan has no in-network appointment inside the standard, it must arrange out-of-network care at in-network cost.³
If the deadline passes, say one word — grievance — and if that goes nowhere, the DMHC Help Center is 1-888-466-2219.³ How to file a DMHC complaint →
Door two: San Mateo County — specialty mental health
The county's own number is (650) 579-0350 — San Mateo County calls it the 24/7 crisis line and mobile crisis team.² We read that number off the county's own page on 17 August 2026; it is not taken from a directory or a helpline list.
No referral is needed. Say:
"I have Medi-Cal. I would like a screening and a referral for ongoing therapy."
A screening runs 15 to 20 minutes and should end with a clinic name, a phone number and a next step. Write down who you spoke to and when.
One local detail worth knowing. Not toll-free. The 24/7 ACCESS call centre is (800) 686-0101.²
Which door is actually yours
The state rewrote these criteria in January 2026, and most published summaries still quote the 2021 version.⁴ The current rule:
- Adults 21 and over belong in the county specialty system if both are true: there is significant impairment, or a reasonable probability of significant deterioration; and it is due to a diagnosed mental health disorder, or one suspected but not yet diagnosed. Everything milder is the plan's job.
- Under 21 is deliberately wider. A young person reaches the county system through either high-risk trauma status — flagged by an approved screening tool, or child-welfare involvement, juvenile-justice involvement, or homelessness — or significant impairment or developmental concern together with a diagnosed, suspected or trauma-related condition.
- Under 21, on the plan side, EPSDT covers all non-specialty mental health services regardless of severity or diagnosis.⁴ What EPSDT covers for under-21s →
Note what the criteria do not require: a diagnosis is not a prerequisite for access on either side.
Nobody may bounce you
This is the rule to quote when you are being passed back and forth. Under the state's No Wrong Door policy, services delivered during an assessment are covered even if the assessment concludes you did not meet the county's criteria — and a plan may not refuse to pay for non-specialty services because the assessment landed on county criteria instead.⁵ You may also receive services from both systems at the same time where they are coordinated and not duplicative, expressly so that an existing relationship with a therapist does not have to be broken.⁵
Two more numbers, for when a door will not open: the Medi-Cal Managed Care Ombudsman is (888) 452-8609, and the DHCS Mental Health Ombudsman is (800) 896-4042.¹
The Bay Area trap is the drive, not the wait. Plans here have real networks, but the clinic with the soonest opening is often three cities away. Ask for the earliest appointment anywhere in the plan's network, including telehealth — not the earliest at the nearest office. A telehealth visit is a covered visit, and it is frequently weeks faster.
