The Real Cost of Rehab in Southern California

By SoCal Addiction Centers Editorial Team | Last reviewed: | 10 min read Clinically Reviewed

Key Takeaways

  • Medi-Cal covers residential and outpatient addiction treatment at zero cost for eligible Californians through the Drug Medi-Cal Organized Delivery System (DMC-ODS), currently active in all six Southern California counties.
  • Medicare covers up to 190 lifetime days of inpatient substance-use treatment in a participating psychiatric hospital. Outpatient coverage under Part B has no lifetime day cap.
  • Private-pay residential treatment in SoCal typically runs $15,000–$30,000 for a 30-day program at a CARF-accredited mid-market facility. Luxury concierge programs in Malibu, Newport Beach, and Rancho Mirage run $40,000–$80,000+ for 30 days.
  • Medically-monitored detox (ASAM Level 3.7) adds $5,000–$15,000 private-pay on top of residential, or is fully covered under Medi-Cal DMC-ODS and most commercial plans.
  • Intensive Outpatient (IOP) runs $3,000–$10,000 per month private-pay; Partial Hospitalization (PHP) runs $7,000–$14,000 per month.
  • Verify license status before paying. 155 DHCS-licensed SUD facilities in the six SoCal counties had licenses expire more than 30 days before this page was last reviewed. Check the DHCS Licensing and Certification lookup before signing anything.

How much does rehab cost in Southern California?

Residential rehab in Southern California ranges from $0 on Medi-Cal DMC-ODS to $80,000+ per month at Malibu concierge facilities. A mid-market 30-day program at a CARF-accredited residential facility typically costs $15,000–$30,000 private-pay. Intensive outpatient runs $3,000–$10,000 monthly. Detox adds $5,000–$15,000. Rates vary by ASAM level of care, county, and insurance coverage.

The six Southern California counties — Los Angeles, Orange, San Diego, Riverside, San Bernardino, and Ventura — currently hold 1,501 active DHCS-licensed SUD facilities, according to the California Department of Health Care Services Recovery Treatment Facilities public dataset. Prices inside that footprint vary by more than three times depending on county, accreditation status, ASAM level of care, and whether the patient is using Medi-Cal, Medicare, commercial insurance, or paying cash.

All pricing on this page is assembled from public DHCS license filings, CARF-accredited roster analysis, Medi-Cal DMC-ODS rate schedules published by the state, and insurance Summary of Benefits documents. We do not accept facility-supplied numbers and we do not publish pricing that cannot be independently cross-referenced. SoCal Addiction Centers maintains no financial relationships with the facilities named below — no referral fees, no paid listings, no sponsored content.

How much is 2 weeks of rehab?

Two weeks of residential rehab at a CARF-accredited facility in Southern California costs approximately $7,500–$15,000 private-pay at a standard residential program. The same 14 days at a luxury concierge facility (Malibu, Newport Beach, Rancho Mirage) runs $20,000–$40,000. Two weeks of medically-monitored detox alone (ASAM 3.7) runs $5,000–$15,000 private-pay. Medi-Cal DMC-ODS members pay $0 for any of these under current California state funding.

Two-week stays are less common than 30-day stays in residential treatment. ASAM’s clinical guidelines generally place the minimum effective residential stay at 28 days for most substance-use disorders, with methamphetamine and opioid-use disorder patients frequently benefiting from 60–90 days. Facilities that advertise “two-week programs” at the residential level are either (a) running short-term detox-plus-stabilization before step-down to IOP, or (b) operating programs shorter than clinical guidelines recommend. Ask directly which of those you are purchasing.

Detox, by contrast, routinely runs 5–14 days and is frequently billed separately from residential. A 14-day stand-alone medical detox for alcohol, benzodiazepines, or opioids is clinically common and the $5,000–$15,000 private-pay range is accurate for SoCal CARF-accredited detox programs.

How many days will Medicare pay for rehab?

Medicare Part A covers inpatient substance-use treatment under the same 190-day lifetime limit that applies to inpatient psychiatric hospitalization, per the CMS Medicare Benefit Policy Manual, Chapter 2. That cap applies only to psychiatric hospitals (not general acute-care hospitals or free-standing SUD residential programs). Inside the 190-day cap, Medicare Part A covers:

  • Days 1–60: full coverage after the Part A deductible ($1,676 in 2026)
  • Days 61–90: daily coinsurance (approximately $419/day in 2026)
  • Days 91–190: “lifetime reserve days” coinsurance (approximately $838/day in 2026), each day used counts against the 60 lifetime reserve days across all inpatient stays

Medicare Part B covers outpatient substance-use treatment — IOP, PHP, MAT office visits, counseling — with no lifetime day cap, subject to the Part B deductible and 20% coinsurance. Medicare began covering Intensive Outpatient Programs as a distinct benefit category in 2024 under the Consolidated Appropriations Act.

Medicare Advantage plans (Part C) must cover everything Original Medicare covers and often add benefits. Check the specific plan’s Summary of Benefits for SUD coverage details.

Does Medi-Cal pay for rehab in California?

Yes. Medi-Cal covers substance-use disorder treatment at zero out-of-pocket cost to eligible California residents through the Drug Medi-Cal Organized Delivery System, known as DMC-ODS. All six Southern California counties participate in DMC-ODS:

DMC-ODS covers the full ASAM continuum: outpatient services, intensive outpatient, partial hospitalization, residential treatment, withdrawal management (detox), medication-assisted treatment (methadone, buprenorphine, naltrexone), recovery services, and case management. There is no enrollment fee, no copay, and no per-day charge for covered services at participating DMC-ODS providers.

Eligibility requires current Medi-Cal enrollment and a clinical determination that SUD treatment is medically necessary — a standard that is not difficult to meet for active substance-use disorder. A facility’s contracted status with DMC-ODS is independent of its CARF or Joint Commission accreditation; some DMC-ODS providers are CARF-accredited, some are not.

Patients without current Medi-Cal enrollment can apply at BenefitsCal.com or at any county social services office. Retroactive enrollment is sometimes available. The DMC-ODS provider can usually help navigate the enrollment process in parallel with admission.

Is rehab free in California?

Rehab is free in California for Medi-Cal DMC-ODS enrollees and for qualifying patients at county-operated or state-funded programs. Beyond Medi-Cal, “free rehab” in California exists through three additional channels:

State-funded residential programs at county-operated facilities. Each of the six SoCal counties funds a limited number of no-cost residential beds through the Behavioral Health division. Waitlists apply. MLK Jr. Behavioral Health Center in LA County is one example of a county-funded flagship facility with this structure.

VA health care for eligible U.S. veterans. The VA operates substance-use disorder treatment programs at multiple SoCal facilities at no cost to enrolled veterans, independent of the private SoCal treatment market.

Scholarship and sliding-scale beds at some CARF-accredited private residential facilities. These programs — often funded through facility foundation arms or individual donor designations — offer reduced-fee or free residential treatment to patients who can demonstrate financial need. Availability fluctuates. Phoenix House (Santa Ana), The Salvation Army Adult Rehabilitation Centers, and the Betty Ford Center’s scholarship fund are established examples.

“Free rehab” in the sense of no-cost admission to a private luxury facility does not exist. Any program advertising itself as free without identifying its funding source — Medi-Cal, VA, county, or named foundation — warrants verification before admission. Call the California DHCS Licensing and Certification Division at (916) 322-2911 to confirm a facility’s licensure status before any intake paperwork is signed.

Cost by level of care (ASAM)

Pricing in SoCal tracks closely with the ASAM Criteria level of care. These are the ranges our directory sees most consistently across CARF-accredited facilities in the six-county footprint:

ASAM levelClinical descriptionSoCal private-pay range (30 days)Medi-Cal DMC-ODS
Level 1.0Outpatient services (<9 hrs/week)$1,500–$5,000$0
Level 2.1Intensive Outpatient (9+ hrs/week)$3,000–$10,000$0
Level 2.5Partial Hospitalization (20+ hrs/week)$7,000–$14,000$0
Level 3.1Clinically managed low-intensity residential$5,000–$15,000$0
Level 3.3Clinically managed population-specific high-intensity residential$8,000–$20,000$0
Level 3.5Clinically managed high-intensity residential$10,000–$25,000$0
Level 3.7Medically monitored intensive inpatient$15,000–$40,000$0
Level 4.0Medically managed intensive inpatient (hospital)Billed as hospital inpatientHospital admission rules apply

Luxury residential (typically ASAM 3.5 or 3.7) at Malibu, Newport Beach, Rancho Mirage, and select Santa Monica facilities prices above the private-pay ranges in the table — $40,000–$80,000+ for 30 days is typical, with some concierge programs exceeding $100,000. What those prices include varies widely and is covered separately in our Luxury & Executive Rehab pillar.

What insurance covers in SoCal

Commercial insurance coverage for SUD treatment in California is governed by two laws that matter more than the plan’s Summary of Benefits:

Federal parity. The Mental Health Parity and Addiction Equity Act of 2008 requires group health plans to cover SUD benefits no more restrictively than medical-surgical benefits. A plan cannot impose a more restrictive prior-authorization process, higher copay, or different visit limit on SUD care than on comparable medical care.

California state parity. California Health and Safety Code § 1374.72 and related statutes extend parity to individual and state-regulated group plans sold in California, including Covered California marketplace plans.

What this means for cost: if a plan covers residential treatment at all, it must cover residential SUD treatment on parity terms. If the plan’s Summary of Benefits shows an impossibly narrow SUD benefit (e.g., only covering 30 days inpatient per year with no continuing care), that is likely a parity violation and worth appealing. The California Department of Managed Health Care processes parity complaints.

Our separate Insurance Coverage pillar walks through Kaiser Permanente, Anthem Blue Cross, Blue Shield of California, Tricare, and Medi-Cal MCO coverage in detail. For insurance verification without calling facilities (which can trigger sales contact), use our Verify Insurance tool.

Why prices vary so much within Southern California

Three factors explain most of the three-times price variation across SoCal’s 1,501 licensed facilities:

Geography and real estate. A residential facility in Malibu operating out of a $20M beachfront property prices to cover its cost basis. The same clinical program in San Bernardino or Riverside County operates on a fraction of the real-estate overhead. Neither facility is necessarily “better” — they are selling the same ASAM level of care in different packaging.

Accreditation status. CARF accreditation, Joint Commission accreditation, and LegitScript certification each impose quality standards that cost money to achieve and maintain. Facilities without any independent accreditation operate on a lower cost basis but provide less externally-verified quality assurance. Of the 1,346 DHCS-active SUD facilities currently in our six-county dataset, 122 are CARF-accredited for at least one SUD-treatment program. Our directory’s Verified facility tier identifies them.

What’s included. “30 days at $25,000” can mean very different things. Some programs price-in detox, medication, individual therapy, group therapy, family therapy, aftercare planning, and 90 days of continuing-care telehealth. Others price each of those separately and the $25,000 covers only the residential stay. Ask for an itemized good-faith estimate under the No Surprises Act before admission.

Questions to ask before paying

When a facility quotes a price, the numbers only mean something in context. Before writing any check, ask:

  • What ASAM level of care is this quoted rate for? (Detox, residential, IOP, PHP are priced separately.)
  • What is included in this rate — medication, detox, therapy modalities, aftercare, family services?
  • Are you CARF-accredited, Joint Commission-accredited, or LegitScript-certified? For what specific programs?
  • Is this facility currently contracted with my insurance plan? Provide the facility NPI and tax ID to verify independently.
  • Do you offer sliding-scale or scholarship beds? Under what criteria?
  • What is your DHCS license number, and is it currently active? (Cross-reference at dhcs.ca.gov.)
  • What happens to my pre-payment if I leave treatment early?

A facility unwilling or unable to answer these questions is not one worth writing a check to.
