Most inpatient alcohol rehab programs last 28 to 30 days, but stays of 60 or 90 days are common and often recommended for people with severe or long-standing alcohol use. The right length depends on several individual factors, including how much you drink, how long you’ve been drinking, whether you have other mental health conditions, and how your body responds to detox and early treatment.
Standard Program Lengths
Inpatient programs generally fall into three tiers: 30 days, 60 days, and 90 days. The 30-day model is the most widely available and the most commonly covered by insurance. It typically includes medical detox in the first week followed by roughly three weeks of structured therapy, group sessions, and recovery planning. For many people with moderate alcohol dependence and a stable living situation to return to, 30 days provides a solid foundation.
Programs lasting 60 or 90 days offer the same core structure but allow more time to work through deeper psychological patterns, practice coping skills, and stabilize before returning to daily life. These longer stays are frequently recommended for people who have relapsed after shorter programs, those with co-occurring conditions like depression or anxiety, or anyone whose home environment poses a high risk for relapse. Research consistently shows that longer treatment durations correlate with better long-term outcomes, particularly for people with severe dependence.
Some residential programs extend beyond 90 days into what’s often called extended care or therapeutic community treatment, which can last six months to a year. These are less common and typically reserved for people with very high-severity addiction or unstable housing situations.
What Happens During Detox
The first phase of any inpatient stay is medical detoxification, and for alcohol this is a critical period. Alcohol withdrawal can be dangerous, producing symptoms ranging from tremors and anxiety to seizures. Withdrawal symptoms typically peak within the first two to three days. After stabilization, medications used to manage withdrawal are gradually tapered over 7 to 10 days. So detox alone can account for roughly the first 10 days of your stay before the deeper therapeutic work truly begins.
This is one reason a 30-day program can feel short. Once detox is complete, you may have only about three weeks of active therapy. For people whose withdrawal is particularly severe or complicated, that window shrinks further.
How Clinicians Decide Your Length of Stay
The most widely used framework for placement decisions is the ASAM Criteria, developed by the American Society of Addiction Medicine. Clinicians assess six dimensions of your health: your physical condition, any withdrawal risks, other medical or psychological conditions, your readiness to change, your risk of relapse, and your living environment. These factors together determine not just whether you need inpatient care but how long you should stay.
Your treatment plan isn’t locked in on day one. Clinicians reassess regularly and adjust the recommendation based on how you’re progressing. Someone who stabilizes quickly and has strong support at home might step down to outpatient care sooner. Someone struggling with cravings, unresolved trauma, or co-occurring mental health issues will likely be advised to stay longer. The goal is matching the intensity and duration of treatment to your actual needs at any given point.
What a Typical Day Looks Like
Inpatient rehab is structured and intensive. Most programs involve several hours of therapeutic activity each day, including individual counseling, group therapy, educational sessions about addiction, and skill-building workshops. Expect a consistent daily schedule that starts early and fills most of the day, with time set aside for meals, exercise, and rest. Weekly team meetings involving your counselor, a physician, and often a case manager or social worker help guide your treatment plan.
This level of structure is one of the key advantages of inpatient care over outpatient treatment. You’re removed from the triggers and routines of daily life, which gives your brain and body the chance to reset without the constant pull of old habits.
How Much It Costs
Cost is often the factor that determines program length in practice. A 30-day program at a private facility typically runs between $5,000 and $20,000, with an average around $12,500. Programs lasting 60 to 90 days range from $12,000 to $60,000, averaging about $36,000. The daily cost at private facilities averages roughly $575.
State-run facilities are significantly cheaper, sometimes free, but they come with longer wait times and fewer program options. Publicly funded long-term programs can cost $8,000 or more for specialized care but remain far more affordable than private alternatives.
Insurance typically covers some portion of inpatient treatment when it’s deemed medically necessary. However, insurers conduct their own medical necessity reviews and may authorize only a certain number of days at a time, requiring your treatment team to justify continued stay. This means your actual length of stay can be shaped as much by your insurance plan as by clinical recommendations. Medicare, for example, covers inpatient days with no coinsurance for the first 60 days after you meet the annual deductible, but costs increase significantly beyond that point.
Protecting Your Job During Treatment
If you’re employed and worried about taking time off, the Family and Medical Leave Act provides up to 12 weeks of unpaid, job-protected leave per year for eligible employees. Substance abuse treatment qualifies as a serious health condition under FMLA, as long as the treatment is provided by or referred by a health care provider. Your employer cannot take action against you for exercising this right.
One important distinction: FMLA protects leave taken for treatment, not for substance use itself. If you miss work because of drinking, that’s not covered. But time spent in inpatient rehab is. This protection also extends to employees who need leave to care for a family member receiving treatment.
After Inpatient Care
Inpatient rehab is the most intensive phase of recovery, but it’s rarely the final one. Most treatment plans include a step-down to less intensive care after discharge. This might mean transitioning to an outpatient program where you attend therapy several times a week while living at home, or moving into a sober living house where you have more independence but remain in a substance-free environment with peer support.
The transition out of inpatient care is one of the highest-risk periods for relapse. Having a clear aftercare plan before you leave, including ongoing therapy, support group involvement, and a stable living situation, significantly improves your chances of staying sober. Many people find that the real work of recovery begins after they leave the protected environment of inpatient treatment and start applying what they learned to everyday life.
