About drug and alcohol rehab in California

Substance use treatment ranges from short-term outpatient counseling to long-term residential rehab and medication-assisted treatment. The right level of care depends on the substance, severity, mental-health co-occurrence, and home support.

Services typically offered

Insurance, Medicare, and Medicaid coverage

Most providers accept some combination of Medicaid, Medicare (limited), private insurance, sliding-scale self-pay, and state-funded coverage for those without insurance. Federal parity laws require most plans to cover addiction treatment at the same level as physical health care.

Medi-Cal covers drug and alcohol rehab through the Home and Community-Based Alternatives (HCBA) waiver program. To qualify, residents typically need to meet the financial threshold (about 138% FPL ($1,732/month for an individual in 2026)) and have a documented care need that would otherwise require nursing-facility-level care. Applications go through California Department of Health Care Services (DHCS), which is also the licensing authority for these providers.

California Medicaid & eligibility deep dive

Eligibility for Medi-Cal

To qualify for drug and alcohol rehab under Medi-Cal, applicants generally need to meet two criteria: financial eligibility and a documented care need. Financial eligibility is based on income — typically 138% FPL ($1,732/month for an individual in 2026) — and on countable assets, usually capped around $2,000 for an individual (with separate rules for spouses). The care-need test typically requires a level-of-care assessment showing the applicant would need nursing-facility-level care without home- and community-based support.

The Home and Community-Based Alternatives (HCBA) waiver program

California's primary vehicle for drug and alcohol rehab coverage is the Home and Community-Based Alternatives (HCBA) waiver. Covered services typically include outpatient counseling, intensive outpatient programs, partial hospitalization, residential treatment for qualifying conditions, medication-assisted treatment for substance use disorder, and crisis intervention. Some programs require pre-authorization through a managed-care organization.

How to apply

  1. Complete the Medicaid application through California Department of Health Care Services (DHCS) (www.dhcs.ca.gov/), by phone, in person at a local office, or through healthcare.gov.
  2. Provide income documentation (pay stubs, tax returns, Social Security benefit letters), bank statements, and proof of citizenship or legal residency.
  3. Once enrolled in Medicaid, request a long-term services and supports (LTSS) assessment to determine eligibility for the Home and Community-Based Alternatives (HCBA) waiver.
  4. If approved, you can choose any participating drug and alcohol rehab provider — the ones listed below all accept Medicaid where they have contracts.

Application timelines vary: Medicaid itself can be approved in 30–45 days for most applicants, while waiver enrollment may take 60–180 days due to assessments and waitlists. Some California regions have shorter waitlists than others — typically urban metros move faster than rural counties.

How to choose a drug and alcohol rehab provider

When you compare drug and alcohol rehab providers, focus on five things: (1) certification status (Medicare- or Medicaid-certified for clinical care; SAMHSA-listed for behavioral health), (2) services offered relative to the specific need, (3) which insurance plans and Medicaid waivers they accept, (4) how quickly they can start, (5) patient and family reviews where available. Reputable providers explain coverage, costs, and care plans up front; high-pressure sales tactics are a red flag.

Before signing a care agreement, ask for the answers to these questions in writing: which services are billed to Medicare/Medicaid versus billed to you out of pocket; who is the primary care coordinator; how the agency handles after-hours calls and emergencies; the typical response time for new requests; and two or three references from current patients or families. Providers who refuse to share references are a yellow flag — keep looking.

Frequently Asked Questions

How much does drug and alcohol rehab cost in California?

Cost varies dramatically based on level of care. Outpatient counseling can be $50–$200 per session with insurance; intensive outpatient runs $3,000–$10,000 for a typical course; residential treatment ranges from $5,000 to $30,000+ for 30 days. Medi-Cal covers drug and alcohol rehab for qualifying residents, and most providers below accept sliding-scale or state-funded coverage for the uninsured.

Does Medicaid cover drug and alcohol rehab in California?

Yes. Medi-Cal covers drug and alcohol rehab through Home and Community-Based Alternatives (HCBA) waiver. Eligibility is based on financial need (typically 138% FPL ($1,732/month for an individual in 2026)) and a documented care need that would otherwise require nursing-facility-level care. Apply through California Department of Health Care Services (DHCS) or use the federal portal at healthcare.gov.

How do I choose the right drug and alcohol rehab provider?

Compare providers on five things: (1) certification status — Medicare/Medicaid certified or, for behavioral health, SAMHSA-listed; (2) services offered relative to your specific needs; (3) which insurance plans and Medicaid waivers they accept; (4) how quickly they can start care; (5) patient and family reviews where available. Reputable agencies provide written care plans, clear cost breakdowns, and answer questions without high-pressure sales tactics.

What's the difference between inpatient and outpatient rehab?

Inpatient (residential) rehab: the patient lives at the facility for 28–90+ days, with 24-hour clinical supervision. Best for severe addiction, multiple relapses, unsafe home environment, or co-occurring mental health needs. Outpatient: the patient lives at home and attends treatment 1–5 days per week. Levels include standard outpatient (1–2 hrs/week), Intensive Outpatient Programs (IOP, 9–20 hrs/week), and Partial Hospitalization Programs (PHP, 20+ hrs/week). The right level depends on substance, severity, and home support.

Are these providers verified?

Yes. Every facility on this page is listed in the federal SAMHSA FindTreatment.gov national directory and refreshed monthly. SAMHSA (Substance Abuse and Mental Health Services Administration) is the U.S. government agency responsible for behavioral health services. Inclusion in their directory means the facility has reported its services and contact info to the federal government.

Does Senova charge for using this directory?

No. Senova is free for patients and families. We never charge to view providers, request a callback, or save vendors to your account. We don't sell your contact information. Providers can also list their agency for free; we offer optional paid plans only for premium features like priority placement on relevant searches.

Can I request a call back from a specific provider?

Yes. Click "Request vendor to contact me" on any provider card. If you're not signed in, you'll be prompted to create a free account first (takes 30 seconds) so the provider has your contact info. Your request is logged in your profile under "Callback Requests" — you can track which providers you've contacted and when.

Are reviews on Senova verified?

Reviews labeled "Verified" come from users who used Senova to request a callback from that provider — meaning they had a real interaction. Unverified reviews come from any signed-in user. We don't allow anonymous reviews and we don't accept paid reviews from providers. If you spot a review that looks fake, contact us at hello@senova.info.

What's the difference between Medicare and Medicaid for drug and alcohol rehab?

Medicare is the federal health insurance for people 65+ and certain younger adults with disabilities — it covers drug and alcohol rehab when criteria are met (homebound status, physician order, skilled need). Medicaid is the joint federal-state program for low-income Americans — it covers drug and alcohol rehab more broadly through state HCBS waivers. Many people qualify for both ("dual-eligible") and use them together to maximize coverage.

What if I'm in a mental-health or substance-use crisis right now?

Don't wait for a directory listing — call or text 988 immediately for the Suicide & Crisis Lifeline (free, confidential, 24/7), or call SAMHSA's helpline at 1-800-662-4357 for substance use treatment referrals. If there's immediate danger to yourself or someone else, call 911 or go to the nearest emergency room. The providers below are for ongoing treatment after the immediate crisis is stabilized.

How often is the data on this page updated?

Senova refreshes the underlying federal datasets on the 1st of every month. SAMHSA FindTreatment.gov publishes updates approximately quarterly, and we sync within 24 hours of their release. Provider information that changes more often (phone numbers, addresses, accepted insurance) is only as current as the federal source — call the provider directly to confirm critical details before scheduling care.
