Getting into rehab typically starts with a single phone call, either to a treatment facility directly, to your insurance company, or to a free national helpline. The process from that first call to walking through the doors can take anywhere from a few hours in an emergency to a couple of weeks for planned admissions. Here’s what the process actually looks like, step by step.
Start With a Phone Call
You have three main starting points. The first is calling a treatment facility directly. Most rehab centers have admissions staff available around the clock who will ask basic questions about what substance you’re using, how much, how long, and whether you have insurance. They can often tell you within that first conversation whether they’re a good fit and whether they have a bed available.
The second option is calling your insurance company’s behavioral health number, printed on the back of your card. They’ll walk you through what your plan covers and give you a list of in-network facilities. The third is SAMHSA’s national helpline at 1-800-662-4357, which is free, confidential, and available 24/7. They can refer you to local facilities, including those offering sliding-scale fees or state-funded treatment if you don’t have insurance. You can also search facilities yourself at FindTreatment.gov, a federal database updated annually from surveys of every licensed treatment provider in the country.
What Happens During the Assessment
Once you contact a facility, the next step is an intake assessment. This is a structured interview that covers six areas of your life: your current substance use and withdrawal risk, any medical conditions, your mental and emotional health, how ready you feel to make changes, your risk of relapse, and your living situation and support system. This framework, developed by the American Society of Addiction Medicine, is the standard used across the field to figure out the right level of care for each person.
The assessment isn’t a pass/fail test. Its purpose is to match you with the least intensive level of treatment that’s still safe and effective for your situation. Someone with a stable home, mild use patterns, and no medical complications might be placed in outpatient care. Someone going through severe withdrawal or living in an environment that makes recovery dangerous would likely need residential or inpatient treatment. Some of this assessment happens over the phone before admission, and the rest is completed in person when you arrive.
Understanding the Levels of Care
Rehab isn’t one thing. It’s a spectrum of treatment settings, and knowing the differences helps you understand what’s being recommended and why.
- Outpatient (fewer than 9 hours per week): You live at home and attend therapy sessions, group meetings, or counseling a few times a week. This works for people with milder substance use issues or as a step down after more intensive treatment.
- Intensive outpatient (9 to 19 hours per week): A significant time commitment, but you still sleep at home. Sessions typically run three to five days a week for several hours at a time.
- Partial hospitalization (20+ hours per week): You attend a structured clinical program most of the day, most days of the week, but return home in the evenings. This level includes daily monitoring.
- Residential treatment (24-hour care): You live at the facility full-time. Programs range from low-intensity residential, with at least 5 hours of treatment services per week in a structured setting, to clinically managed residential for people with severe social or psychological conditions who need an immersive environment.
- Medically monitored inpatient: A 24-hour facility with physicians on-site around the clock for people who need direct medical observation, often during detox or when complex medical conditions are involved.
- Hospital-based inpatient: The highest level, with daily physician care and 24-hour nursing. This is reserved for people with severe medical, emotional, or cognitive conditions that need primary medical attention alongside addiction treatment.
Most people picture “rehab” as a 28- or 30-day residential stay, and that is one common format. But many people enter treatment at the outpatient or intensive outpatient level and never need to leave home.
If You Need Detox First
If your body has become physically dependent on a substance, particularly alcohol, opioids, or benzodiazepines, you’ll likely go through medical detox before starting a treatment program. Detox is not rehab itself. It’s the process of safely clearing the substance from your system under medical supervision.
Timelines vary by substance. Alcohol withdrawal symptoms can begin within 6 to 12 hours of your last drink, starting with anxiety, tremors, sweating, and nausea. More dangerous complications, including seizures, can develop between 24 and 48 hours after stopping. The most severe form, delirium tremens, typically appears between 48 and 72 hours. People with mild to moderate withdrawal symptoms and no history of complicated withdrawal may be able to detox in an outpatient setting. Those at risk for seizures or delirium need 24-hour medical monitoring.
Medical staff use standardized scales to measure how severe your withdrawal is and adjust care accordingly. Detox generally lasts three to seven days for most substances, though some withdrawal timelines run longer. Once you’re medically stable, you transition into the treatment program itself.
Paying for Treatment
Federal law requires most health insurance plans to cover substance use disorder treatment on the same terms as other medical care. The Mental Health Parity and Addiction Equity Act prohibits insurers from setting higher copays, stricter visit limits, or more burdensome prior authorization requirements for addiction treatment than they do for comparable medical or surgical benefits. This applies to both employer-sponsored plans and individual marketplace plans. If your insurer is making it harder to access addiction treatment than, say, physical therapy or cardiac rehab, that may be a parity violation you can report.
Call your insurer before choosing a facility to understand your deductible, copay, and whether a particular program is in-network. Many residential facilities also offer payment plans. If you don’t have insurance, state-funded treatment programs exist in every state, and SAMHSA’s helpline can connect you with options in your area. Some facilities operate on a sliding scale based on income.
Protecting Your Job
The Family and Medical Leave Act allows eligible employees to take unpaid, job-protected leave to enter treatment for substance abuse. The key requirement is that the treatment must be provided by or referred by a health care provider. Simply being absent from work because of substance use, without entering a treatment program, does not qualify.
Your employer cannot retaliate against you for exercising your right to take FMLA leave for treatment. However, there’s an important exception: if your employer has a written, non-discriminatory substance abuse policy that was communicated to all employees, they can enforce that policy regardless of whether you’re currently on leave. In practical terms, this means it’s worth reading your employee handbook before disclosing anything. FMLA also protects employees who need time off to care for a spouse, child, or parent who is going into treatment.
To qualify for FMLA, you need to have worked for your employer for at least 12 months and logged at least 1,250 hours in the past year, and your employer must have 50 or more employees within a 75-mile radius.
When Someone Won’t Go Voluntarily
Most rehab admissions are voluntary, but every state has some legal mechanism for families to pursue when a loved one’s substance use puts them in immediate danger. These laws vary significantly by state. Florida’s Marchman Act allows family members to petition a court for involuntary assessment and treatment. Massachusetts has a similar process under Section 35.
Washington State’s law, known as Ricky’s Law, is one example of how these processes work. A designated crisis responder evaluates the individual on the scene. If they determine the person is a danger to themselves or others, or is gravely disabled due to a substance use disorder, the person can be detained at a secure withdrawal management facility for an initial period of up to 120 hours, followed by up to 14 days of civil commitment for detox and stabilization. This applies to adults and adolescents over 13.
Involuntary commitment is a last resort and a legally complex process. If you’re considering this path for a family member, contacting your county’s crisis services line or a local addiction attorney is the most direct way to learn what’s available in your state.
What to Bring and How to Prepare
If you’re entering a residential program, most facilities will send you a packing list after your intake call. Generally, you’ll want to bring comfortable clothing for about a week (laundry is usually available), basic toiletries without alcohol-based products, any prescription medications in their original bottles, your insurance card and ID, and a list of emergency contacts. Most facilities restrict or prohibit electronics, so ask about their phone and laptop policies beforehand.
Before you leave, handle the logistics that could become stressors while you’re away: set up auto-pay on bills, arrange care for pets or children, notify your employer, and let one or two trusted people know where you’ll be. The less you have to worry about on the outside, the more you can focus on the work inside.
