What Is Inpatient Opiate Treatment? A Complete Guide

Inpatient opiate treatment is 24-hour residential care for opioid use disorder, combining medical detox, therapy, medication management, and relapse prevention in a structured live-in setting. This guide explains who qualifies, what the typical stay looks like, what it costs, and how to find a program that fits your situation and insurance.

Inpatient Opiate Treatment, Defined

Inpatient opiate treatment is a level of care in which a patient lives at a licensed addiction treatment facility around the clock while receiving medical and behavioral health services for opioid use disorder. Stays are typically 28 to 90 days, and the program combines four core components: medically supervised detox, individual and group therapy, medication-assisted treatment when clinically indicated, and discharge planning into aftercare. Inpatient care is the standard of care for moderate-to-severe opioid use disorder because of two clinical realities — opioid withdrawal is physically dangerous when unmanaged, and the relapse risk in the first weeks of recovery is among the highest of any substance use disorder.

The American Society of Addiction Medicine (ASAM) classifies this level of care as Level 3.7 — medically monitored intensive inpatient services — when the facility has 24-hour nursing and on-call physician coverage. Hospital-based opioid treatment is Level 4. Both settings differ from outpatient (Levels 1 and 2) and partial hospitalization (Level 2.5) primarily in the degree of medical supervision and the fact that the patient sleeps at the facility.

Who Qualifies for Inpatient Opiate Treatment?

Qualification is determined by a clinical assessment, not by how long someone has been using or how much they use. Clinicians use the six ASAM dimensions to recommend a level of care:

1. Acute intoxication and withdrawal potential. Patients with significant physiological dependence on opioids — daily heroin or fentanyl use, high-dose prescription opioid use, or polysubstance use with benzodiazepines or alcohol — generally need 24-hour supervision during withdrawal.
2. Biomedical conditions. Co-occurring medical conditions such as pregnancy, hepatitis C, HIV, cardiac disease, or chronic pain often make residential care safer than outpatient detox.
3. Emotional and behavioral conditions. Co-occurring depression, anxiety, PTSD, bipolar disorder, or active suicidal ideation generally indicate a higher level of care.
4. Readiness to change. Patients with low motivation often benefit from the structure and removal from triggers that residential care provides.
5. Relapse potential. A history of repeated relapses, recent overdose, or fentanyl exposure raises the bar for level of care.
6. Recovery environment. Patients without a safe, sober, supportive home are appropriate for residential care almost regardless of severity, because outpatient treatment depends on a stable environment between sessions.

What Inpatient Opiate Treatment Includes

A complete inpatient opioid program includes the following components, integrated into a single continuous course of care.

1. Medical Detox (Days 1–10)

The first phase is medically supervised withdrawal management. On admission, the patient is assessed by a physician or nurse practitioner, and medications are started to control withdrawal symptoms. Buprenorphine (the active ingredient in Suboxone) is the most common detox medication for opioid use disorder, followed by methadone in some hospital-based settings, and clonidine or other comfort medications when buprenorphine is contraindicated. Acute opioid withdrawal generally peaks at 36–72 hours and subsides over 5–10 days. Vital signs and withdrawal scores are monitored multiple times per day during this phase.

2. Residential Therapy (Days 5–90)

Once acute withdrawal stabilizes, the patient transitions into the active treatment phase. This typically includes:

• Individual therapy with a licensed counselor, often using cognitive behavioral therapy (CBT), motivational interviewing, or trauma-focused approaches
• Group therapy covering relapse prevention, coping skills, family dynamics, and recovery education
• Psychiatric care for co-occurring mental health conditions, with medication management as needed
• Medication-assisted treatment with buprenorphine or extended-release naltrexone for patients who are clinically appropriate
• Family programming to involve loved ones in recovery and prepare for discharge
• Recreational and wellness programming — exercise, mindfulness, art or music therapy, nutrition
• 12-step or peer recovery meetings on-site or in the community

3. Discharge Planning & Aftercare

Discharge planning starts within the first week of treatment and intensifies as the stay nears completion. A typical aftercare plan includes a step-down to outpatient therapy or partial hospitalization, continuation of MAT through a community provider, sober living placement when home is not stable, ongoing psychiatric care, and connection to peer support such as Narcotics Anonymous or SMART Recovery. The discharge plan is critical — research consistently shows that patients with structured aftercare relapse at significantly lower rates than those who return home without a plan.

How Long Does Inpatient Opiate Treatment Last?

The three most common program lengths are 30, 60, and 90 days. Each has clinical merit depending on the patient's situation.

Program Length	Best For	Typical Cost (Self-Pay Range)
28–30 days	First-time treatment, employed adults with stable home, lower-severity OUD	$15,000–$30,000
60 days	Repeat treatment, patients with co-occurring conditions, moderate severity	$25,000–$50,000
90 days	Severe OUD, fentanyl exposure, multiple relapses, polysubstance use	$30,000–$80,000+

NIDA's research-based principles of effective treatment state that "remaining in treatment for an adequate period of time is critical" and recommends that most patients need at least 90 days of treatment to significantly reduce or stop drug use. For opioids specifically, longer stays correlate with lower one-year relapse rates, and many clinicians consider 90 days the threshold for measurably better outcomes.

What Does Inpatient Opiate Treatment Cost?

Self-pay rates for inpatient opiate treatment in the United States typically run $500 to $2,000 per day, with luxury and executive programs reaching $3,000 per day or more. A standard 30-day stay falls between $15,000 and $30,000; a 90-day stay between $30,000 and $80,000. With insurance, most patients pay only a fraction of these numbers — typically a deductible plus a coinsurance percentage, capped by their annual out-of-pocket maximum.

Does Insurance Cover Inpatient Opiate Treatment?

Yes — and federal law requires it. The Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) requires most commercial health insurance plans to cover substance use disorder treatment at parity with medical and surgical care. The Affordable Care Act expanded that requirement to most individual and small-group plans. In practical terms, this means that if your plan covers inpatient hospitalization for a medical condition, it must cover medically necessary inpatient opioid treatment under comparable terms.

Most major commercial carriers — Blue Cross Blue Shield, Aetna, Cigna, UnitedHealthcare, Humana, Anthem, Optum — pay for inpatient opiate detox and residential rehab when medically necessary. Verification takes about 10 minutes and tells you exactly what your out-of-pocket cost will be. Read our complete insurance guide →

Inpatient vs. Outpatient Treatment for Opioids

For most patients with moderate-to-severe opioid use disorder, inpatient is the safer and more effective starting point. Outpatient treatment depends on the patient remaining sober between sessions, which is extraordinarily difficult during early recovery from opioids. The risk of fatal overdose during a relapse — particularly with fentanyl in the drug supply — makes the controlled environment of residential care a meaningful safety intervention. Outpatient treatment is appropriate as a step-down after residential care, or as a primary level of care for patients with mild OUD, strong recovery support at home, and no significant co-occurring conditions.

Frequently Asked Questions

How do you qualify for inpatient rehab?

Qualification for inpatient opioid rehab is based on a clinical assessment using the American Society of Addiction Medicine (ASAM) criteria. The assessment looks at six dimensions: acute intoxication and withdrawal risk, biomedical conditions, emotional and behavioral conditions, readiness to change, relapse potential, and recovery environment. A patient is generally appropriate for residential level of care (ASAM Level 3) if they have moderate-to-severe opioid use disorder, are at risk of dangerous withdrawal, lack a safe and supportive home environment, or have failed at lower levels of care. Most adults using heroin, fentanyl, or high-dose prescription opioids meet criteria. The intake clinician at the facility — not the insurance company — makes the determination, and our placement specialists can pre-screen you over the phone in about 15 minutes.

How long can you stay in inpatient rehab?

Standard inpatient opiate rehab lengths are 28–30 days, 60 days, and 90 days. Stays can be extended when a clinician documents medical necessity, and some patients stay 120 days or longer. Research from the National Institute on Drug Abuse repeatedly shows that opioid treatment outcomes improve with longer residential stays, with 90 days often cited as the threshold for measurably better one-year outcomes. Insurance authorizations are typically reviewed every 7–14 days during the stay, and the facility utilization review team handles re-authorization on the patient's behalf.

What happens during opiate detox?

Inpatient opiate detox manages withdrawal under 24-hour medical supervision. On admission, the patient is assessed and stabilized, often with the first dose of buprenorphine or another comfort medication. Over the next 5–10 days, vital signs are monitored multiple times per day, withdrawal symptoms are scored using a tool such as the COWS (Clinical Opiate Withdrawal Scale), and medications are adjusted to keep the patient safe and comfortable. Once acute withdrawal resolves, the patient transitions into the residential rehab phase of treatment. See our detailed guide on the opiate detox process.

What is the difference between inpatient and residential opiate treatment?

Clinically the terms overlap. "Inpatient" historically referred to hospital-based treatment with full medical staffing, while "residential" referred to non-hospital licensed facilities. Today, most insurance plans and clinicians use the terms interchangeably to describe 24-hour live-in addiction treatment outside of a hospital. The American Society of Addiction Medicine groups both as ASAM Level 3 (residential) or Level 4 (medically managed inpatient, hospital-based). For most opioid patients, ASAM Level 3.7 — medically monitored residential — is the appropriate setting.

What does a typical day in inpatient opiate rehab look like?

After detox stabilization, most facilities follow a structured daily schedule: morning medication and medical check, breakfast, individual therapy or psychiatric appointment, group therapy (often cognitive behavioral or relapse prevention focused), lunch, education group or skills-based programming, afternoon recreation or wellness activity, dinner, evening 12-step or community meeting, and lights out. Patients typically receive 30–40 hours of clinical programming per week, which is the threshold most insurers require for residential level of care reimbursement.
