Levels of Addiction Treatment Compared
What Are the Levels of Care in Addiction Treatment?
Treatment runs from most to least intensive: medical detox, hospital inpatient, residential, partial hospitalization, intensive outpatient and outpatient, with medication treatment possible at most levels. They differ in whether you live there, how many hours a week they take and how long they last. A clinical assessment decides which fits you, and your level can change as you progress.
Compare Levels of Care
| Level | Where you live | Time commitment | Typical length | Often suits | Listed facilities |
|---|---|---|---|---|---|
| Medical detox | A hospital ward, an inpatient detox unit, or at home with close medical supervision | Around the clock while withdrawal is managed | Several days to a week or more | People at risk of severe withdrawal. For alcohol, sedative and opioid withdrawal, 24-hour medical care is often the preferred setting. Detox is a first step that prepares you for treatment, not treatment by itself. | 2,318 |
| Hospital inpatient | In a hospital, 24/7 | Around the clock | Days or weeks | People with serious mental health or medical concerns who need detox and rehabilitation care together. | 574 |
| Residential rehab | Live-in, in a non-hospital setting | Around the clock, with house rules for residents and families | One month to one year, usually a few months; therapeutic communities plan 6 to 12 months | People without a stable living or work situation, or with limited family support. | 2,541 |
| Partial hospitalization (PHP) | At home; you go to the program each day | Usually 4 to 8 hours a day, at least 20 hours a week under Medicare's rules | Varies by program and need | People who need structure close to inpatient care but can live at home. | 1,879 |
| Intensive outpatient (IOP) | At home | Usually 9 or more hours a week over 3 to 5 days | Traditionally 4 to 12 weeks, many programs longer | People who need more than weekly counseling while keeping up with work, school or family. Group counseling is the core; sessions often run 90 minutes. | 5,474 |
| Outpatient | At home | Regular office or telehealth visits | Ongoing; most people need at least 3 months in treatment | People with a stable home, reliable transportation and support, often with jobs. Costs less than residential or inpatient care. | 10,175 |
| Methadone clinic (OTP) | At home | Clinic visits for dosing, with take-home doses earned over time | As long as it helps; medication is standard care for opioid use disorder | People with opioid use disorder. | 1,506 |
| Buprenorphine (Suboxone) treatment | At home | Office or telehealth visits with a prescriber | As long as it helps | People with opioid use disorder; it can be prescribed in a doctor's office. | 6,998 |

How Treatment Steps Up and Down
Treatment isn't one fixed program. Many people start with detox if withdrawal could be dangerous, move into residential or intensive outpatient care, then step down to outpatient counseling and recovery support. After intensive treatment, staying in less intensive continuing care helps lower the risk of relapse. Medication for opioid use disorder and medication for alcohol use disorder can be part of care at almost every level.
Alcohol and benzodiazepine withdrawal can be dangerous without medical care. If you drink heavily every day or take benzodiazepines, talk with a clinician before you stop. See withdrawal symptoms and timelines.
What Each Level Costs and Who Pays
Outpatient care costs less than residential or inpatient treatment. Marketplace health plans cover substance use treatment as an essential health benefit, Medicare covers inpatient and outpatient treatment including intensive outpatient services, and most listed facilities accept Medicaid.

Frequently Asked Questions
Who Decides Which Level of Care You Need?
Everyone entering treatment gets a clinical assessment that determines the best type of treatment, and it continues during treatment, so your level of care can change as your needs do.
Is Detox the Same as Rehab?
No. Detox manages withdrawal safely and prepares you for treatment. Treatment afterward, in a residential or outpatient program, works on the substance use itself.
Can You Keep Working During Treatment?
Outpatient and intensive outpatient programs let you live at home and often suit people with jobs. If you need inpatient care, the federal Family and Medical Leave Act can protect your job for eligible workers.
What Is the Difference Between IOP and PHP?
Both let you live at home. Intensive outpatient usually means 9 or more hours a week; partial hospitalization usually means 4 to 8 hours a day, at least 20 hours a week under Medicare's rules.
