Inpatient vs outpatient rehab: which you need, and how long it lasts

If you need help now: call 911 in an emergency. Severe alcohol withdrawal can be life-threatening; see alcohol detox in Texas. In a crisis, call or text 988. SAMHSA's National Helpline, 1-800-662-4357, is free and open 24/7.

Inpatient and outpatient side by side

Level	Where you sleep	Time in treatment	Often a fit when
Inpatient: hospital or residential	At the program	Around the clock	You aren't safe at home, need 24-hour medical care, or lower levels haven't worked
Partial hospitalization (PHP)	At home	At least 20 hours a week	You need a lot of structure but have a safe place to live
Intensive outpatient (IOP)	At home	At least 9 hours a week for adults, often mornings or evenings	You need more than weekly counseling and want to keep working or studying
Outpatient counseling	At home	Usually one or two sessions a week	Milder problems, or a step down after a more intensive level

Detox (withdrawal management) can happen at any of these: outpatient, in a residential program or in a hospital. Medication for alcohol or opioid use disorder can be part of every level. The difference between PHP and IOP: IOP vs PHP vs weekly therapy. How outpatient care works week to week, including for alcohol: outpatient rehab in Texas.

Who needs inpatient rehab

Programs and health plans use the ASAM Criteria, from the American Society of Addiction Medicine, to match people to a level of care. The assessment looks at several areas of your life, including:

• Withdrawal risk: some withdrawal, from alcohol especially, needs 24-hour medical care.
• Physical and mental health: conditions that need close medical or psychiatric care.
• Your home: whether it's safe and supports recovery, or is full of alcohol, drugs or conflict.
• What's happened before: whether outpatient treatment has worked for you, and how likely a return to use is without more support.

The general rule is the least intensive level that's safe and effective, stepping up if you need more. People with little support at home, or an unsafe home, may do better in a more intensive setting.

Does outpatient rehab work?

Yes, for most people. A 2014 review in Psychiatric Services looked at studies of intensive outpatient programs and rated the evidence as high: IOPs were as effective as inpatient or residential treatment for most people, and every study found reductions in substance use. Outpatient care also lets you practice recovery in your real life, with your own triggers, while you have support.

NIDA's research principles add that no single treatment is right for everyone, that treatment should address the whole person, and that medication combined with counseling works best for many people with alcohol or opioid use disorders.

How long rehab lasts

Stage	How long
Detox	Days. Alcohol withdrawal usually peaks 24 to 72 hours after the last drink, though some symptoms last weeks. Texas Medicaid can approve outpatient detox for up to 21 days.
Residential	No fixed length. Health plans approve days in blocks and review your progress before approving more.
PHP and IOP	Often several weeks to a few months, depending on your progress and what your plan approves.
Outpatient and recovery support	Months or longer: counseling, medication, support groups, recovery coaching or sober living.

Is 30 days of rehab enough? NIDA's research says most people need at least 3 months in treatment to significantly reduce or stop their drug use, and the best outcomes come with longer treatment. That's 3 months in all, not 3 months in a residential bed: a few weeks of residential care followed by IOP and outpatient care counts. Ask any program what comes after it, and have the next step booked before you leave.

What a day looks like

• Residential: a full schedule of group and individual counseling, education about addiction, medical and medication care, family sessions, and planning for after discharge, with staff on site day and night.
• PHP: much of the same, most of the day, five or so days a week, home each night.
• IOP: mostly group therapy, about three hours a day, three to five days a week, around work or school, plus individual sessions.

What insurance and Medicaid cover

• Private and Marketplace plans cover inpatient and outpatient rehab when it's medically necessary. Inpatient, PHP and often IOP need prior authorization. See does insurance cover rehab?
• Texas Medicaid covers outpatient counseling, detox and residential treatment at licensed programs, with no copays; detox and residential need prior authorization. Health plans can also cover PHP and IOP in place of inpatient care. See rehab that takes Medicaid in Texas.
• Medicare Part A covers inpatient hospital care, and Part B covers outpatient care, IOP and PHP. Many residential programs aren't hospitals, so ask before you go.
• No insurance: free and state-funded rehab in Texas. What you'd pay for IOP and PHP: IOP vs PHP cost in Texas.

Keeping your job

The Family and Medical Leave Act (FMLA) can cover time off for substance use treatment given by, or on referral from, a health care provider, if you and your employer qualify; absence because of use itself isn't covered (29 CFR 825.119). IOP is often scheduled around work hours. Ask your employer's HR team about leave and any employee assistance program.
