There are five primary levels of addiction treatment, each designed for a specific severity. Per NSDUH (2023), 48.7 million Americans aged 12+ had SUD — only 24.1% received treatment.
What Is Medical Detox and Who Needs It?
Medical detox is a 3–7 day supervised process managing withdrawal with medications. Necessary for alcohol (5–15% mortality from DTs without supervision), benzodiazepines, and opioids. Detox alone is not treatment — it's stabilization. Search detox programs.
How Does Inpatient Rehab Work?
24/7 structured care for 28–90 days. Programs lasting 90+ days produce 2–3× better outcomes (NIDA). Cost: $5,000–$80,000 for 30 days, insurance covers most under Mental Health Parity Act. Browse inpatient programs. Read our guide on paying without insurance.
What Are Outpatient Programs?
IOP (9–15 hours/week) and PHP (20+ hours/week) let you live at home while attending treatment. Cost $1,000–$10,000. Find outpatient options. See our FMLA guide for job-protection.
What Is MAT?
MAT combines FDA-approved medications with counseling. Buprenorphine, methadone, naltrexone for opioids; naltrexone, acamprosate for alcohol. Reduces overdose deaths by 50% (SAMHSA). Search MAT providers.
How to Verify Insurance Before Admission
Most rehab denials are caused by skipped pre-authorization, not by actual lack of coverage. Under the Mental Health Parity and Addiction Equity Act (MHPAEA), every group and marketplace plan must cover medically necessary substance use treatment at parity with medical care. The variable is how each plan verifies medical necessity and which levels of care require prior authorization.
A reliable verification sequence takes 15–30 minutes:
- Locate the member services number on the back of your insurance card. For a plan-by-plan breakdown of typical deductibles and copays across 10 major insurers, see our insurance hub.
- Ask four specific questions: "Is behavioral health / substance use treatment covered under my plan? What's my deductible and coinsurance? Is pre-authorization required for inpatient, residential, or PHP? Do I have out-of-network benefits?"
- Request a written Benefits of Benefits (BOB) letter. Take it to the facility's intake coordinator — most facilities re-verify with the insurer before admission, and inconsistencies at this stage are the single biggest source of surprise bills.
- If denied, appeal. Industry data from KFF shows fewer than 1% of denied behavioral-health claims are appealed — but first-level appeal success rates are around 40%. Federal law gives you 180 days to file an internal appeal; urgent cases decided within 72 hours.
If you're uninsured, Medicaid coverage is available in all 50 states and in 40+ expansion states covers any adult earning up to 138% of the federal poverty level. See our 8-option guide to paying without insurance.
What Makes a SAMHSA-Verified Facility
Every facility listed on RehabPulse is sourced from the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) Treatment Locator — the federal government's official database of licensed addiction treatment providers. Inclusion is not endorsement, but it does mean the facility has met baseline federal requirements: state licensure, compliance with 42 CFR Part 2 (patient confidentiality), and registration with SAMHSA's Behavioral Health Services Information System.
SAMHSA verification adds confidence along four dimensions:
- Licensure: facility holds active state licensure for the levels of care it provides. Unlicensed "recovery coaching" operations — increasingly common in Florida and Arizona — do not appear in the SAMHSA database.
- Reporting obligations: licensed facilities file annual census data with SAMHSA, which makes their capacity and service mix publicly auditable. Red-flag facilities that quietly close or change scope tend to drop from SAMHSA within 12–18 months.
- Clinical oversight: most SAMHSA-listed facilities carry additional voluntary accreditation — CARF International (52% of behavioral facilities) or The Joint Commission (18%). Accredited facilities show measurably lower staff turnover and better continuity of care per SAMHSA's 2023 N-SSATS survey.
- Data freshness: SAMHSA refreshes its treatment locator quarterly; our directory inherits these updates. If you call a listed facility and find it closed, contact us and we'll verify with SAMHSA.
SAMHSA verification is a floor, not a ceiling. For higher-quality signals, layer it with CARF/Joint Commission accreditation and ask facilities about their specific program outcomes, not just credentials.
Red Flags to Avoid When Choosing a Rehab
The rehab industry has a documented problem with predatory marketing, particularly in areas with high insurance reimbursement (South Florida, Malibu, Arizona). The Federal Trade Commission has brought enforcement actions against operators for patient brokering, kickback schemes, and deceptive outcome claims. A 2020 GAO report found that roughly 7% of self-identified "rehab centers" in SAMHSA's database had pending regulatory actions against them — a small minority, but enough that user vigilance matters.
Walk away if you see any of these patterns during the inquiry process:
- Guaranteed outcomes. No legitimate facility promises "95% success" or "permanent recovery." Addiction is a chronic condition with variable outcomes — ethical providers discuss realistic remission rates (50–80% with sustained treatment per NIDA).
- Aggressive sales pressure: "We only have one bed left, you need to decide today." Legitimate facilities give you time to verify benefits and consult with family.
- Unsolicited outreach after searching online. If a facility contacts you without you reaching out first, they likely purchased your lead from a broker — a practice banned by the Eliminating Kickbacks in Recovery Act of 2018.
- Cash-only pricing without itemized billing. Even self-pay facilities should provide clear breakdowns (room/board vs clinical services vs medical management). Avoid "all-inclusive" quotes with no line items.
- Frequent facility rebranding: same address, new name every 12–24 months. This pattern often indicates a facility rotating ownership to escape complaints or regulatory scrutiny. You can search facility history through state corporate records.
- No medical director listed. Any facility offering detox or MAT must have a licensed medical director; residential facilities should also have 24/7 medical staffing. If you can't find the MD's name on the facility's website or state licensing records, that's a significant red flag.
When in doubt, use SAMHSA's free National Helpline (1-800-662-HELP) for an unbiased facility referral, or call our helpline for free insurance verification across multiple facilities.
How Long Does Rehab Actually Last?
"How long is rehab?" is the single most-asked question among people considering treatment, and the honest answer is: it depends, but longer is usually better. NIDA's Principles of Drug Addiction Treatment explicitly states that durations shorter than 90 days are of "limited effectiveness" for severe SUD. That finding has held across replication studies since 1999. Yet the 28-day residential program remains the market standard — not because 28 days is clinically optimal, but because it fit early insurance coverage ceilings.
Typical durations by level of care:
- Medical detox: 3–7 days. Not treatment itself — stabilization before treatment. Detox alone produces 80%+ relapse without follow-up care.
- Short-term residential: 28–30 days. The insurance-default program. Works for some mild-moderate cases but shows worse long-term outcomes than longer stays for severe SUD.
- Mid-length residential: 60 days. A compromise tier — enough time for medication stabilization and initial behavioral skill-building but before employment/housing disruption becomes severe.
- Long-term residential: 90 days+. NIDA's evidence-backed floor for severe SUD. 90-day retention rates correlate with 2–3× better 12-month remission per NIDA's seminal DATOS study.
- Partial Hospitalization Program (PHP): 20+ hours/week for 2–6 weeks, often as step-down from residential or step-up from IOP.
- Intensive Outpatient (IOP): 9–15 hours/week for 8–12 weeks. The most common modality overall.
- Standard outpatient: 1–3 sessions/week, open-ended duration. Often years-long for maintenance phase.
- MAT maintenance: medication-assisted treatment for opioid or alcohol use disorder is typically multi-year. Some patients safely taper after 1–2 years of stability; others remain on buprenorphine or methadone indefinitely — a legitimate clinical choice with strong evidence.
If insurance pushes toward shorter stays, concurrent review with documented medical necessity can often extend authorization. Under MHPAEA, insurers cannot apply stricter day-limits to SUD than they apply to medical care. If clinical notes document ongoing need, extensions are frequently approved — but only when requested before current authorization expires.
