This guide walks through what rehab is, the levels of care it can mean, how long people usually stay and what to check before committing: state licensing, accreditation from the Joint Commission or CARF, and the signs of a center that is not what it advertises. It also covers paying for care and whether to stay near home.
Key Points About Rehab and Choosing a Center
- Rehab is treatment for a substance use disorder, while detox only manages withdrawal as a substance leaves the body.
- Outpatient care is most common, at 83.8% of facilities, against 22.5% with residential care outside a hospital (SAMHSA, 2025).
- No single level of care fits everyone, so an assessment should decide where you start, not a brochure (NIDA).
- Verify a center’s state license and accreditation from the Joint Commission or CARF before you enroll or share insurance details.
- Ads posing as real centers, call lines that hide who answers and free travel offers are reasons to check further.

What Is Drug and Alcohol Rehab?
Rehabilitation is what the word shortens. In drug and alcohol care, it names treatment for a substance use disorder, and a rehab center is where that treatment happens, whether someone stays on site or comes in a few times a week.
Licensing or accreditation is common but not universal, so verify credentials before enrolling. Rehab treats the disorder itself. What detox is is narrower than that: supervised care while a drug leaves the body, easing withdrawal without treating the disorder. Here, rehab means addiction treatment, not physical therapy after an injury.
In 2024, 15,953 U.S. facilities provided substance use treatment, according to the Substance Abuse and Mental Health Services Administration (SAMHSA). Outpatient care is the most common offering, at 83.8% of facilities, followed by residential care outside a hospital at 22.5%, with hospital inpatient care at 7.5%.
That range is why an assessment comes before placement. As the National Institute on Drug Abuse (NIDA) puts it, “No single treatment is appropriate for everyone.”
Types of Rehab Programs
Rehab programs divide into two broad settings. In residential care, a person lives at the program; in outpatient care, they attend treatment while living at home. Between those two ends sit partial hospitalization and intensive outpatient care.
The American Society of Addiction Medicine (ASAM) ranks these levels by how much support they provide, and the ASAM Criteria give programs, clinicians and insurers a shared way to describe them. An assessment against those criteria decides which level fits a person. The full levels of care compared, detox, hospital care and medication rows included, sit in the wider treatment guide.
| Program | ASAM level | Where a person lives | What it involves | Learn more |
|---|---|---|---|---|
| Residential (inpatient) rehab | 3.1, 3.5, 3.7 | At the program | Staff on site around the clock; therapy, groups and structure, plus medical care at level 3.7 | Inpatient rehab |
| Partial hospitalization (high-intensity outpatient) | 2.5 | At home | Sessions for much of the day across several days each week | Partial hospitalization programs |
| Intensive outpatient (IOP) | 2.1 | At home | Several sessions a week, often built around work or school | Outpatient rehab |
| Outpatient therapy | 1.5 | At home | Regular counseling or therapy visits | Outpatient rehab |
Level 2.5 is where names often trip people up. ASAM calls it high-intensity outpatient care, and many programs still call that level partial hospitalization.
Medication for opioid or alcohol use disorder, sometimes described as medication-assisted treatment, can be part of any level. Withdrawal management is built into the medically managed levels (1.7, 2.7, 3.7 and 4) and into clinically managed residential care (3.5), and where detox happens varies with the setting.
NIDA holds that a treatment plan should be reviewed and adjusted as a person’s needs change, which is why a stay can start at a higher level and finish at a lower one.

What a Rehab Program Includes
Most rehab programs open with an assessment and a treatment plan built from it. Care usually combines therapy, medical attention and support.
Behavioral therapies “are the most commonly used forms” of treatment for drug use disorders, according to the National Institute on Drug Abuse (NIDA). The Substance Abuse and Mental Health Services Administration (SAMHSA) counts FDA-approved medications for alcohol and opioid use disorders among its five signs of quality care, with family involvement and ongoing support.
None of those medications is approved yet to prevent relapse for other substances, SAMHSA notes.
Care for co-occurring disorders sits alongside any of this. Programs also run on structure and routine.
How Long Rehab Lasts
There is no single right length, and no one can name yours at intake. NIDA’s research finds that most people need 3 months of treatment or more before their drug use falls significantly or stops, and staying longer is tied to better results. Those months often cover more than one level of care, running from residential care into outpatient care.
Many programs advertise fixed stays, though a published schedule is not a clinical recommendation and how long rehab lasts still comes down to the person. Length gets reviewed as care goes on. The ASAM Criteria’s continued-service criteria give care teams a shared way to judge whether someone’s progress still fits their level of care, and to adjust it.
How to Check a Rehab’s License and Accreditation
A state license comes first: it is permission to operate, and to offer those services, in that state. CARF and The Joint Commission both accredit programs, meaning an outside group measured the program against that organization’s standards. LegitScript certification and NAATP membership are signals worth checking, and neither replaces a license or an accreditation.
SAMHSA’s 2024 survey of treatment facilities found 95.8% of facilities treating substance use disorders held a license, certification or accreditation from at least one agency: 69.0% through a state substance use agency, 33.9% CARF, 25.9% The Joint Commission.
SAMHSA suggests two questions about a program’s standing: “Has the program been licensed or certified by the state?” and “Is the program currently in good standing in the state?”
| Credential | Who issues it | What it tells you | What it doesn’t tell you | How to check |
|---|---|---|---|---|
| State license | Your state’s substance use or health agency | It may legally offer these services there | Whether it is accredited, or offers medication | Get the license number, then check it with the agency |
| Joint Commission accreditation | The Joint Commission | The organization met its behavioral health standards | Whether every service line is covered | Its Quality Check search |
| CARF accreditation | CARF International | The services met CARF’s quality standards | Whether your program is the one accredited | CARF’s Find a Provider search |
| LegitScript certification | LegitScript | Licensing, transparency and advertising standards were met | How good the care is; it is not accreditation | Ask the program, or use its lookup |
| NAATP membership | The National Association of Addiction Treatment Providers | A trade group requiring licensing, accreditation and ethics | Whether it holds either one | Ask the program, or check its website |
LegitScript certification answers a narrower question: it certifies that a provider meets standards for licensing, transparency and honest advertising, and Google’s addiction services policy has required it of U.S. advertisers since 2018. LegitScript calls it independent verification of those standards, not a judgment of quality.
NAATP is a trade association, so membership is not accreditation. Its member terms require a license, an accreditation and a code of ethics.
How to Choose a Rehab Center: Questions to Ask
Start with a short list, then ask every program the same questions. Search FindTreatment.gov, or browse treatment centers by state and city for what is near you. The SAMHSA National Helpline answers calls at 1-800-662-HELP (4357) and TTY 1-800-487-4889, and takes texts at 435748.
The Addictions.com helpline connects you with a treatment provider who can go over programs, insurance and start dates. Calling commits you to nothing.
Fit depends on cost, work and family needs, as well as age, gender, culture and language.
Programs vary on medication: 61.7% of facilities offered medication for opioid use disorder in 2024, according to SAMHSA’s National Substance Use and Mental Health Services Survey.

CostRed Flags When Choosing a Rehab
Some businesses pose as treatment centers, and some are paid to steer people to particular programs. If something feels off, check the program yourself before sharing insurance details.
In a 2026 alert, the Federal Trade Commission (FTC) advised skipping the paid search results and typing a center’s address straight into the browser, since impostors answered calls with “Admissions” or “Recovery helpline”. A 2025 alert described businesses advertising under real centers’ names, and pointed searches to FindTreatment.gov and reports to ReportFraud.ftc.gov.
- An ad leads somewhere other than the center.
- The person answering will not name the facility.
- Free travel, housing, cash or gifts to enroll.
- No current state license to show.
- One program for everyone, no assessment.
- A promised cure or guaranteed results.
Each Addictions.com number carries a label showing who answers before you call.
A kickback paid or received for a referral to a treatment facility or recovery home is a federal crime under the Eliminating Kickbacks in Recovery Act, subject to a fine of up to $200,000, a prison term of up to 10 years, or both, for each occurrence. A 2017 Massachusetts Attorney General advisory described recruiters covering travel or insurance for enrollees, an old example of the tactic, not today’s enforcement. LegitScript requires certified providers to disclose any incentives they offer patients. NIDA calls addiction chronic, with relapse rates of 40% to 60% like other chronic illnesses, so relapse does not mean treatment failed.
Paying for Rehab: Insurance and Low-Cost Options
Health insurance is accepted at most rehab programs, and many accept Medicaid. Some charge little or nothing when someone cannot pay. Since insurance coverage varies by plan, ask your insurer and the program what you will owe before intake.
HealthCare.gov says: “All Marketplace plans cover mental health and substance abuse services as essential health benefits.” Parity applies under the Mental Health Parity and Addiction Equity Act, though the 2024 rule’s newer provisions are not being enforced, the Departments of Labor, Health and Human Services, and the Treasury said on May 15, 2025.
SAMHSA’s 2024 N-SUMHSS survey, released in 2025, found 78.3% accepting private insurance, 77.8% accepting Medicaid and 46.3% offering free or minimal-payment care across all substance use treatment facilities.
Ask a program about how to get into rehab with no money, and expect rehab costs without insurance to vary by setting and length of stay.
Rehab Close to Home or Farther Away?
Staying close to home keeps family able to take part and makes the same outpatient care easier to continue; a program farther away offers distance from the routine, or a specialty that is scarce nearby.
Either way, two questions matter: is the program licensed where it sits, and will the plan pay for care there? Treatment centers by state keeps both in view.
The National Institute on Drug Abuse says family and friends can be decisive in getting a person with a drug problem into treatment and keeping them there.
| Option | Possible advantages | Things to check |
|---|---|---|
| Close to home | Family can join sessions; the same outpatient care can continue | Whether it fits the person, not just the map |
| Elsewhere in the state | More programs to compare, and plan networks usually stay the same | Family visits and follow-up care mean time on the road |
| Out of state | A break from the familiar; specialty programs | That state’s license, out-of-network costs, who pays for travel |
Travel is the other cost to pin down: a distant program’s offer to cover it is a detail to examine, not a reason to enroll.
Frequently Asked Questions About Rehab
Rehab is short for rehabilitation. In substance use care, it means treatment for a drug or alcohol use disorder. What rehab involves runs from the first assessment through aftercare.
Detox manages withdrawal, when a substance clears the body. Rehab treats the disorder itself, with therapy, medical care and ongoing support. Many people move from one to the other.
Check a program’s license and accreditation, then put the same questions to each one. Red flags include a promised cure, a refusal to name the facility, or free travel to enroll.
It varies. Most people need 3 months of treatment or more, NIDA reports, and often move through more than one level of care. Length depends on the person and the program.
It depends on the setting, how long the stay runs and what your coverage pays. Paying without insurance turns on the same three things.
All Marketplace plans cover substance use treatment, according to HealthCare.gov, and most treatment facilities take private insurance or Medicaid, according to SAMHSA. What you owe depends on the plan, so check insurance coverage for rehab before intake.
HIPAA covers health information, and 42 CFR Part 2 goes further for records held by substance use treatment programs that receive federal assistance. According to the Department of Health and Human Services, Part 2 also restricts how those records can be used in legal proceedings unless you consent or a court orders it.
Usually not. Many programs take people who reach out on their own. Some health plans require a referral or prior approval, so ask the plan before an intake.
