How much does rehab cost in California by level of care?

In California, the level of care sets the price. Residential programs cost $6,000–$45,000 a month because you live on site with 24-hour care; standard outpatient therapy costs $1,200–$5,000 a month because you live at home. Detox is charged by the day at $230–$800.

California rehab costs by level of care, before insurance (2027 prices)
Level of care	Cost per day	Cost per month	Typical (midpoint)	Typical length
Medical detox	$230–$800	$7,000–$24,000	$515 a day	3–10 days
Residential (inpatient)	$200–$1,500	$6,000–$45,000	$25,500 a month	30–90 days

Source: RehabSeekers.com Rehab Cost Survey, 2027 prices before insurance. “Typical” is the midpoint of the lowest and highest price California centers quoted. Monthly figures assume 30 days.

Why is California the most expensive state for residential rehab?

The difference is at the top of the market. The cheapest residential quote we got in California, $6,000 a month, matched the cheapest quote in most states. But the most expensive reached $45,000 a month, the highest in our 50-state survey, and the widest range of any state. That pulls California’s typical residential price up to $25,500.

How California ranks among all 50 states

California has the most expensive residential rehab in the country. Its typical price of $25,500 a month is 55% above the national median.
The gap is mostly about residential care. California detox ($515 a day) and PHP ($11,250 a month) are only 9% and 5% above the median, and standard outpatient care is right at it.
IOP sits high: only 6 states have a higher typical price than California’s $6,500 a month, though 26 cost less.
Every neighbor is cheaper for residential care. In Arizona, it typically costs $10,000 a month less.

California rehab prices ranked against all 50 states, before insurance
Level of care	Typical price	vs. U.S. median	Rank among 50 states	Cheapest neighbor
Medical detox	$515 a day	9% above the U.S. median	17 states cost more, 30 cost less, 2 the same	California is the cheapest
Residential	$25,500 a month	55% above the U.S. median	The most expensive of all 50 states	Arizona, $15,500 a month ($10,000 less)
PHP	$11,250 a month	5% above the U.S. median	15 states cost more, 34 cost less	Arizona, $10,750 a month ($500 less)
IOP	$6,500 a month	8% above the U.S. median	6 states cost more, 26 cost less, 17 the same	Tied with Arizona and Oregon ($6,500 a month)
Standard outpatient	$3,100 a month	At the U.S. median	19 states cost more, 12 cost less, 18 the same	California is the cheapest

Typical price is the midpoint of each state’s price range in the RehabSeekers.com Rehab Cost Survey, 2027 prices. States with the same typical price count as tied. See rehab costs in all 50 states.

For other levels of care, California is much closer to the rest of the country. If an assessment shows you don’t need 24-hour care, PHP or IOP can cost a fraction of a residential stay, and a lower-priced residential program can offer the same core therapies as a high-end one. Ask every program for a written list of what is included.

Is rehab cheaper in Arizona, Nevada or Oregon?

For residential care, yes: every neighboring state costs less. Typical residential rehab runs $15,500 a month in Arizona, $18,500 in Oregon and $21,000 in Nevada, compared with $25,500 in California. For detox and standard outpatient care, California is slightly cheaper than its neighbors; PHP and IOP prices are close.

Before you travel, check that your coverage follows you. Medi-Cal and county-funded programs generally pay for care in California, and a private plan may treat an out-of-state program as out of network. Aftercare is easier to keep up close to home, too.

Does Medi-Cal cover rehab in California?

Yes. Medi-Cal, California’s Medicaid program, covers addiction treatment, and it has charged no copayments since July 1, 2022. California delivers this care through counties rather than through Medi-Cal health plans: your plan screens you and refers you to your county’s substance use program.

Your county decides the benefit. As of January 1, 2025, 40 counties ran the Drug Medi-Cal Organized Delivery System (DMC-ODS), which covers outpatient, intensive outpatient, withdrawal management, residential and inpatient care, opioid treatment programs and medication for addiction treatment. Other counties offer the narrower Drug Medi-Cal benefit.
No hard limit on residential days. DMC-ODS uses a 30-day statewide average length of stay as a goal, not a cap, and you can start treatment before a formal diagnosis.
Residential funding. Federal approval to pay for treatment in larger residential facilities runs through December 31, 2026. The state asked the federal government to renew it for 2027–2031 in May 2026; approval was still pending when this page was checked.
Contingency management. California was the first state to win federal approval to cover contingency management, small rewards for meeting recovery goals in stimulant use disorder treatment, through its Recovery Incentives Program in participating counties.
Who qualifies and how to apply. California expanded Medi-Cal on January 1, 2014, to adults with incomes up to 138% of the federal poverty level. Apply through BenefitsCal, Covered California or your county office.

Medi-Cal health plans such as L.A. Care, Health Net and Kaiser Permanente refer members to county treatment. See all rehabs that accept Medi-Cal.

How does SB 855 affect what you pay with private insurance?

SB 855, in effect for California-regulated plans issued or renewed since January 1, 2021, requires health plans to cover medically necessary treatment for every substance use disorder, judged by generally accepted standards of care such as the ASAM Criteria. Plans cannot limit coverage to short-term or acute treatment, so residential, intensive outpatient and inpatient care are covered benefits.

If no in-network program can see you in time

Under SB 855, when no in-network provider can offer timely care within the required distance, your plan must arrange out-of-network care for you, and you pay the same out-of-pocket costs as you would in network.

You still pay your deductible, copays and coinsurance up to your plan’s out-of-pocket maximum. SB 855 applies to plans regulated by California’s Department of Managed Health Care and Department of Insurance. If your employer’s plan is self-funded, ask your HR team which rules apply. Federal parity law still requires most plans that cover addiction treatment to cover it on terms similar to medical care. See rehab by insurance provider.

How can you pay for rehab in California without insurance?

Start with your county. The California Department of Health Care Services passes federal block-grant money to county behavioral health departments, which run or contract local treatment programs. Counties must prioritize pregnant women, women with dependent children and people who inject drugs.

County help with insurance costs: Since January 2021, counties can use block-grant money to cover deductibles, coinsurance and copays (not premiums) for privately insured people when cost stands in the way of treatment.
Check Medi-Cal: With no copays, it is the lowest-cost route if you qualify.
Ask about self-pay rates and payment plans: Many California programs discount for paying directly or spread the cost over months.
Use your EAP or HSA/FSA funds: Employee assistance programs offer free counseling and referrals, and addiction treatment is generally a qualified medical expense.

Find state-funded programs in the RehabSeekers.com directory. For a national overview of payment options, see rehab costs in the United States.

Which way of paying for rehab costs least in California?

For most people, Medi-Cal is the cheapest route, because it charges no copays. A California-regulated health plan is next, capped by your out-of-pocket maximum. County-funded care helps people without coverage, and self-pay means paying the prices on this page, ideally with a discount or payment plan.

Ways to pay for rehab in California, compared
How you pay	What you pay	Good to know
Medi-Cal	No copays since July 2022	Treatment comes through your county; DMC-ODS counties offer the full range of care
Private or Covered California plan	Deductible and cost-sharing up to your out-of-pocket maximum	SB 855 requires coverage of medically necessary treatment in California-regulated plans
Medicare	Part A and Part B deductibles and coinsurance	Covers hospital inpatient care and outpatient treatment, not most non-hospital residential programs
County-funded care	Set by the program, based on ability to pay	Priority for pregnant women, women with dependent children and people who inject drugs
Self-pay	$6,000–$45,000 a month residential; $1,200–$5,000 a month outpatient	Ask for a self-pay discount and a written list of what is included

What do high-end California rehab programs cost?

At the top of the market, California residential rehab reached $45,000 a month in our survey, or $1,500 a day. That is the most expensive quote we recorded anywhere in the country, and it is the main reason California’s typical price is so high.

Higher prices usually buy comfort and attention rather than a different kind of treatment: private rooms, more individual therapy hours, a higher staff-to-client ratio, and extras such as fitness facilities or holistic therapies. The core of good care, including an assessment, evidence-based therapy, medical oversight and a discharge plan, is available across the price range. If you are comparing a $6,000 program with a much pricier one, ask both for their weekly schedule, therapist credentials and what is billed on top. A cheaper program you can afford to stay in for longer may serve you better than a short stay at a premium one.

How can you lower the cost of rehab in California?

Check Medi-Cal eligibility first. With no copays, it can bring the cost of treatment close to zero.
Use your county. County behavioral health departments can fund treatment and, since 2021, may help privately insured people with deductibles and copays.
Insist on an in-network program, or use SB 855. If no in-network program can see you in time nearby, your California-regulated plan must arrange care at in-network cost.
Step down when it is clinically appropriate. California IOP costs $3,000–$10,000 a month, a fraction of residential care.
Compare programs, not just cities. The gap between California’s cheapest and priciest residential quotes was $39,000 a month.

What does each type of rehab cost in California?

Medical detox: $230–$800 a day

Most detox stays last 3 to 10 days. Detox covers 24-hour medical monitoring, medication to ease withdrawal, a bed and meals, and a plan for what comes next; lab work and take-home prescriptions are sometimes extra. It is the first step, not the whole treatment, especially for alcohol, benzodiazepines and opioids.

Estimated medical detox cost in California by length
Detox length	Estimated total before insurance
3 days	$690–$2,400
5 days	$1,150–$4,000
7 days	$1,610–$5,600
10 days	$2,300–$8,000

Residential rehab: $6,000–$45,000 a month

The price usually includes your room, meals, individual and group therapy, nursing care and discharge planning. High-end California programs add private rooms, more one-on-one therapy and amenities, which is where the top of the range comes from. NIDA notes that most individuals need at least 3 months of treatment, so compare 30-day, 60-day and 90-day programs on total cost, and look for dual diagnosis care if you need it.

Estimated residential rehab cost in California by length of stay
Length of stay	Estimated total before insurance	Good to know
30 days	$6,000–$45,000	A standard short-term stay, often followed by PHP or IOP
60 days	$12,000–$90,000	More time to stabilize and practice coping skills
90 days	$18,000–$135,000	NIDA says most individuals need at least 3 months of treatment

Partial hospitalization: $7,500–$15,000 a month

Five to six hours of treatment most weekdays, with group and individual therapy and medical check-ins, while you live at home or in supportive housing. Housing and transportation are usually extra. See PHP programs.

Intensive outpatient: $3,000–$10,000 a month

Three to five sessions a week, often in the evening, so you can keep working. A three-month IOP costs $9,000–$30,000. See IOP programs and evening treatment.

Standard outpatient: $1,200–$5,000 a month

One or two counseling sessions a week, the most affordable level of care. Prescriber visits for medication for opioid use disorder are often billed separately; Medi-Cal covers these medications.

Ask every California program about these extra costs

Is detox included, or billed as a separate stage?
Are medications, lab work and drug testing included?
Are psychiatric visits for co-occurring conditions extra?
What does the family program cost?
Is there a fee for sober living or aftercare after discharge?

How much does a full course of rehab cost in California?

Going from detox to residential care, then stepping down through PHP and IOP, can cost $21,110–$85,600 in California before insurance. Most of that is the residential month; PHP and IOP typically cost less per day than detox or residential care.

Example: what a full step-down course of care can cost in California
Stage	Length	Estimated cost before insurance
Medical detox	7 days	$1,610–$5,600
Residential treatment	30 days	$6,000–$45,000
Partial hospitalization	30 days	$7,500–$15,000
Intensive outpatient	60 days	$6,000–$20,000
Full course of care	127 days	$21,110–$85,600

Three ways a California treatment plan can add up

Real treatment plans rarely follow one script. Here is what three common paths would cost at California prices if you paid yourself, before any insurance, Medi-Cal or county help.

Example California treatment paths and their cost before insurance
Path	What it includes	Estimated cost
Outpatient-first	5 days of detox, then 3 months of IOP	$10,150–$34,000
One month residential	7 days of detox, 30 days residential, then 2 months of standard outpatient	$10,010–$60,600
Long-term residential	90 days residential, then 3 months of standard outpatient	$21,600–$150,000

The spread inside each row comes almost entirely from the residential range, which runs from $6,000 to $45,000 a month in California. Choosing a program near the lower end of that range, or stepping down to IOP when your clinician agrees, has the biggest effect on what you pay. With Medi-Cal, which has no copays, the same paths can cost little or nothing.

How many Californians need addiction treatment?

About 5.6 million Californians age 12 and older, or 16.65%, had a past-year substance use disorder (2023–2024 average), according to SAMHSA’s state estimates. In 2024, 82.18% of Californians classified as needing substance use treatment did not receive it.

The CDC’s provisional data counts 9,687 drug overdose deaths in California in the 12 months ending December 2024. Cost is one of the barriers behind that treatment gap, which is why no-copay Medi-Cal, county programs and SB 855 matter. Research supports the spending: NIDA estimates that every $1 invested in addiction treatment returns $4 to $7 in reduced drug-related crime, criminal justice costs and theft.

How we collected California rehab prices

A team of researchers commissioned by RehabSeekers.com called at least five addiction treatment centers in every state, across multiple cities, and asked the price of each level of care before insurance. California’s ranges run from the lowest to the highest price California centers quoted.
