865 of the 1,393 California programs in our directory don't charge, are government-run, offer reduced fees or accept Medicaid. Call a program to confirm what it charges and whether you qualify.
Each count comes from the payment details programs report in our directory. The counts overlap: a program with a sliding scale that also takes Medicaid appears in both. When one organization lists a site more than once, it counts once.
Programs that don't charge, are government-run or offer reduced fees are listed first, followed by programs whose low-cost option is Medicaid. Showing 81 to 100 of 865.

There's no single national rule. Each state runs its own publicly funded treatment system and sets its own eligibility rules. In California, California Department of Health Care Services (DHCS) oversees publicly funded substance use services.
Federal rules do set some priorities. Programs that get SAMHSA substance use block grant funds and serve women have to give pregnant women preference for admission. Funded programs that serve people who inject drugs give treatment preference in this order:
A program that reports "no payment accepted" doesn't charge patients. Government-run programs may still bill insurance or use a sliding scale, and eligibility can depend on where you live, your income and whether you're insured. Ask before you go.
California Department of Health Care Services (DHCS) is the California agency for publicly funded substance use treatment. Visit the California Department of Health Care Services (DHCS) website for help finding treatment.
588 of the 1,393 California programs in our directory say they accept Medicaid, and 377 accept a state-financed health plan other than Medicaid. California's Medicaid program is Medi-Cal.
State Medicaid programs cover addiction treatment to different degrees. Whether detox, residential care, outpatient programs or medication for opioid use disorder are covered depends on California's rules and your plan, so check with both the program and your plan. Check eligibility and apply.
In California, substance use treatment programs are licensed or certified by California Department of Health Care Services, Licensing and Certification Division. Check the state's provider list.
Some programs are. Of the 1,393 California programs in our directory, 38 report that they accept no payment, and 137 are run by a state, county or tribal agency. 25 more are run by the VA, the Department of Defense or the Indian Health Service. Those programs serve only eligible veterans, military health system patients or American Indian and Alaska Native patients. Government-run programs can still bill insurance or charge on a sliding scale, so ask about cost when you call. If you have no insurance, SAMHSA's National Helpline (see samhsa.gov) can refer you to California Department of Health Care Services (DHCS), which handles state-funded treatment.
588 of the 1,393 California programs in our directory say they accept Medicaid. California's Medicaid program is Medi-Cal. State Medicaid programs cover addiction treatment to different degrees, so ask the program and your Medicaid plan which services are covered before you start.
It depends on the type of care, how long it lasts and the program itself. Outpatient care usually costs less than a residential stay. In California, 483 programs in our directory use a sliding fee scale based on income, and 296 offer payment assistance. Ask for the self-pay rate and whether you qualify for a reduced fee before you're admitted.
Under federal block grant rules, programs that get block grant funds and serve women must give pregnant women preference for admission. Funded programs that serve people who inject drugs give treatment preference in this order: pregnant women who inject drugs, other pregnant women with a substance use disorder, people who inject drugs, and then everyone else (45 CFR 96.131). Other eligibility rules vary by state, so ask the program or California Department of Health Care Services (DHCS).
A sliding fee scale sets what you pay based on your income and other factors. Payment assistance varies more: each program decides what help it offers, so ask what's available and what paperwork you'll need.
Yes. Veterans can ask the VA about substance use treatment through VA health care. American Indian and Alaska Native people can contact the Indian Health Service or a tribal health program about alcohol and substance use services.
