90-Day Inpatient Rehab in Las Vegas, Nevada
The strongest outcomes data in addiction treatment supports stays of 90 days or longer for severe substance use disorder, prior relapse, and dual diagnosis. PPO insurance accepted; once the out-of-pocket maximum is reached, the rest is covered.
A 90-day inpatient stay is the right answer for clients whose disorder, history, or environment make 30 days insufficient. The peer-reviewed evidence is clear: longer stays produce better one-year abstinence rates, especially for opioid use disorder, methamphetamine use, and patients with serious co-occurring conditions.
What is the success rate of 90-day rehab?
Across the addiction-treatment outcomes literature, length of stay is one of the strongest single predictors of one-year abstinence. Patients who complete 90 days inpatient show roughly 1.5–2x higher one-year abstinence rates than those who complete 30-day stays for moderate-to-severe substance use disorder. The effect is largest for opioid use disorder, methamphetamine use, and patients with significant trauma history or co-occurring mental health conditions. See dual diagnosis treatment.
How much does 90-day rehab cost in Las Vegas?
Self-pay: $40,000–$90,000 at standard inpatient programs, $150,000+ at luxury programs. With in-network PPO insurance, the out-of-pocket maximum is typically reached during the first 30 days; days 31–90 then accrue at $0 cost-sharing for the patient. Total out-of-pocket cost for 90 days is usually identical to 30 days — $0–$3,500 — because the OOP max is the cap. Our cost guide covers the math.
What\'s the longest you can stay in rehab?
Inpatient stays of 120 to 180+ days are clinically appropriate for severe, complex cases. Therapeutic communities and long-term rehab programs run 6–12 months. PPO insurance can authorize stays beyond 90 days with strong concurrent medical-necessity documentation, though it gets harder. Court-ordered cases often run 6 months. See court-ordered rehab.
What happens in 90-day inpatient rehab?
Days 1–14: medical detox and acute stabilization. Days 15–45: intensive residential treatment — daily individual therapy, multiple groups per day (CBT, DBT, motivational interviewing, contingency management, relapse prevention), psychiatric stabilization on appropriate medications, beginning trauma work, family contact. Days 46–75: deeper trauma processing (EMDR, prolonged exposure, somatic therapies as appropriate), family programming and family discharge meetings, vocational and educational assessment, gradual privilege expansion with off-site outings and weekend passes. Days 76–90: comprehensive discharge planning — sober-living placement, IOP enrollment, MAT continuation, relapse-prevention plan, primary-care reconnection.
Who benefits most from 90 days?
- Patients with moderate-to-severe substance use disorder as defined by DSM-5 criteria.
- Anyone with multiple prior treatment failures at the 30-day or outpatient level.
- Active opioid use disorder involving fentanyl — see our fentanyl rehab page.
- Methamphetamine use disorder — see our meth rehab page.
- Patients with significant trauma history or PTSD requiring extended trauma-focused therapy.
- Anyone with unstable housing or an active-use environment to return to.
- Court-mandated cases with explicit duration requirements.
What 90 days makes possible
The first 30 days handle stabilization. The middle 30 days handle the deeper clinical work — trauma, family systems, identity beyond use. The final 30 days handle reintegration: vocational planning, family discharge meetings, transition to outpatient and sober living, and relapse-prevention rehearsal. Trying to compress all three phases into 30 days is why 30-day-only stays often relapse. The data backs this up.
Frequently Asked Questions
- What is the success rate of 90-day rehab?

Studies of patients in 90-day inpatient programs show 1-year abstinence rates approximately 1.5–2x higher than 30-day-only stays for moderate-to-severe substance use disorder. The effect is largest for opioid, methamphetamine, and dual-diagnosis populations.
