An Opioid Treatment Program is a clinic regulated by the federal government that provides medication-assisted treatment for opioid use disorder, usually methadone. Methadone is a long-acting opioid that reduces withdrawal and craving so a person can stabilize. It is dispensed on site, and the first weeks typically involve daily visits. SAMHSA oversight and state licensing set the rules for dosing, take-home privileges, and required counseling. Clinics also offer buprenorphine or extended-release naltrexone where appropriate.
A typical day starts with a dosing window, often early morning, where a nurse dispenses the medication and checks in briefly. Many programs then schedule individual or group counseling, drug testing, and periodic medical review. As stability is documented, some people earn take-home doses and less frequent visits. The routine is structured but designed to fit around work and family over time.
If your first clinic is full or too far, then ask about the other OTPs in your county; 129 methadone clinics across California are listed, and travel time matters when dosing is daily at the start.

Methadone clinic California costs
More methadone treatment in California is paid for by Medi-Cal than by any other payer, and 120 of the 129 OTPs take it. Private insurance is accepted at 107 programs, while 118 take Medicare. Federal parity law generally means health plans that cover substance use and mental health services must offer them on the same terms as medical care, although methadone clinics are sometimes run separately. When a plan covers methadone clinic California treatment, federal parity law usually calls for the same terms as medical care, so ask for the behavioral health benefit in writing. Because California expanded Medicaid, more low-income adults qualify here than in states that did not. If you have no insurance, 70 clinics offer a sliding fee scale. The helpline is free and private, and its advisors can check which nearby programs accept your coverage.
At a methadone clinic
Intake and assessment
The first visit includes a medical and substance use history, a physical exam, and paperwork. Staff confirm the diagnosis of opioid use disorder and screen for other conditions. Bring identification and insurance information if you have it.
First dose and stabilization
A clinician sets the first dose and watches for sedation or withdrawal. Doses are adjusted gradually over days to weeks. Medical staff should supervise this because methadone stays in the body longer than short-acting opioids.
Counseling and testing
Federal rules require counseling and drug testing as part of treatment. Expect individual sessions and groups, with frequency set by your progress. These services address triggers, housing, and mental health alongside medication.
Take-home eligibility
Take-home doses are earned gradually, based on negative tests, attendance, and stability. Federal and state rules set the timeline, not the clinic alone. Many people eventually visit less often, which helps with work and childcare.
Who methadone may suit
- Adults with an opioid use disorder who want medication to manage withdrawal and cravings while working on recovery goals. Methadone clinic California programs serve people who need longer-term medication support rather than a short detox.
- People who have tried short-term detox and returned to use, and who need longer-term medication support.
- Pregnant individuals with opioid use disorder, for whom methadone is often recommended under medical supervision.
- People with mental health conditions that occur alongside addiction, where a clinic offers dual diagnosis services; 74 of the 129 OTPs in California list that capacity.
Methadone clinics across California
Of the 947 facilities listed on SAMHSA FindTreatment.gov for California, 129 are methadone clinics (OTPs) as of November 2026. Access varies by county, and rural areas may have fewer programs. Spanish-language services are listed at 110 of these clinics, and 117 offer telehealth for some visits, though methadone dosing itself is usually in person. If you live far from a clinic, then telehealth may cover counseling but not the daily dose, so plan travel before intake.
Payment is the practical question. Among the 129 OTPs, 120 accept Medicaid (Medi-Cal), 107 accept private insurance, 118 accept Medicare, and 70 offer a sliding fee scale. Because Medi-Cal covers methadone treatment for eligible adults, cost is often less of a barrier than people expect. Methadone clinic California coverage through Medi-Cal reaches 120 of the 129 listed OTPs, which makes cost a smaller obstacle for eligible adults. If you are unsure about your plan, ask the clinic directly about coverage before your first appointment.

Good to know
How many methadone clinics are in California?

Does Medi-Cal pay for methadone treatment?
Yes, Medi-Cal generally covers methadone treatment at certified OTPs for eligible adults, and 120 of the 129 California OTPs accept Medicaid. Coverage details can vary by county and plan. Ask the clinic's intake staff to verify your eligibility before your first visit so you know what to expect.
How long does methadone treatment last?
There is no set timeline. Some people stay on methadone for months, others for years, depending on their history and stability. Federal rules require periodic reviews, and take-home doses are earned over time. The decision to taper is medical and should be made with your prescriber, never on your own.
Can I take methadone at home?
Take-home doses are allowed only after a period of documented stability, which typically includes negative drug tests and regular attendance. Most people start with daily clinic visits. The exact schedule is set by federal and state rules, and 117 California OTPs offer telehealth for counseling and some visits to reduce travel.
How do methadone and Suboxone differ?
Methadone calls for more structure early on because it is dispensed at an OTP, while buprenorphine (brand name Suboxone) can be prescribed by many clinicians. Both treat opioid use disorder. Suboxone treatment in California is available at 605 facilities that offer medication for opioid use disorder.
Are methadone clinics confidential?
Yes. Federal confidentiality rules protect substance use treatment records, and clinics cannot share them without your written consent except in limited safety situations. A call to the helpline is private too, costs nothing, and commits you to no treatment.
