Searching for the price of rehab is one of the worst experiences in American health care shopping. Most of the top results are marketing pages for treatment centers that will not name a number until you call, and the numbers they do publish are usually somebody else’s estimate of somebody else’s average. This guide takes a different route: it prices each level of care off documents that have to be accurate, namely government payment schedules and hospital price transparency files.
Two things are worth knowing before the table. First, addiction treatment is priced by level of care, not by substance, so alcohol rehab and drug rehab cost the same for the same intensity of service. Second, medication treatment for opioid use disorder costs a small fraction of residential care, and a large share of programs in the country will treat you for free or close to it if you cannot pay. Both of those facts get buried by the advertising.
What Does Rehab Cost Without Insurance?
| Service | Low | Average | High |
|---|---|---|---|
| Medical detox / withdrawal management, per day | $478 | $642 | $2,150 |
| Detox, 5 to 7 day episode | $2,392 | $4,491 | $15,050 |
| Residential rehab (ASAM 3.5), per day | $307 | $389 | Not published |
| Residential rehab, 30 days | $9,197 | $11,660 | Not published |
| Partial hospitalization (PHP), per day | $319 | $418 | $1,250 |
| Intensive outpatient (IOP), per day | $319 | $418 | $750 |
| Methadone at an opioid treatment program, per week | $120 | $277 | Not published |
| Individual addiction counseling, per hour | $106 | Not published | Not published |
The detox low and average come from two state Medicaid schedules. Illinois pays $478.44 per day for medically monitored withdrawal management (ASAM level 3.7) under its Substance Use Prevention and Recovery fee schedule effective July 1, 2025 and updated May 2026. Rhode Island Medicaid pays $641.60 per day for the same level as of July 1, 2025. The high column is a posted self-pay price: Palo Verde Behavioral Health in Tucson lists a discounted cash price of $2,150 per day for inpatient detox in the price transparency file it updated on August 31, 2026, and Physicians Behavioral Hospital in Shreveport lists $1,200 per day in a file dated February 10, 2026.
Residential rehab rows use the same two state schedules for ASAM level 3.5, clinically managed high-intensity residential treatment: $306.55 per day in Illinois and $388.66 per day in Rhode Island, which is $9,197 to $11,660 over 30 days. Rhode Island also publishes $218.23 per day for lower-intensity ASAM 3.1 residential care.
The PHP and IOP rows use Medicare’s CY 2026 hospital outpatient per diems, which are identical for the two programs: $319.38 for a day with three services and $418.45 for a day with four or more (APCs 5861 through 5864, July 2026 OPPS Addendum A). Community mental health centers are paid less for the same day, $127.74 and $167.38. Against those, Palo Verde’s posted cash prices are $1,250 per PHP day and $750 per IOP day, so a standard eight-week IOP at three days a week is about $18,000 at list.
Methadone is the outlier. Medicare’s 2026 weekly bundle for methadone at an opioid treatment program (HCPCS G2067) is $277.29, of which only $44.41 is the drug and $232.88 is dispensing, counseling, group therapy and toxicology testing. Illinois Medicaid’s weekly medication-assisted treatment rate is $119.98. Annualized, that is roughly $6,200 to $14,400 for a year of treatment, against $9,200 or more for a single month of residential care.
What Drives the Price
Level of care, first and last
Every rate schedule in this article prices the same ladder: outpatient counseling, intensive outpatient, partial hospitalization, residential, medically monitored inpatient. Moving one rung up roughly doubles the daily cost. The single largest cost decision is which rung you actually need, and that is a clinical determination made at assessment, not a menu choice.
Whether a bed is involved
A residential day includes room, board and 24-hour staffing. That is why Illinois pays $306.55 for a residential day and $26.62 per 15 minutes of individual counseling, or about $106 an hour, for the same counseling delivered on an outpatient basis. Group counseling is $10.09 per 15 minutes, roughly $40 an hour.
Hospital versus freestanding
Hospital-based and hospital-licensed programs charge more and, usefully, are required to publish their prices. Freestanding residential programs generally are not covered by the federal hospital price transparency rule, which is exactly why credible list prices for 30-day residential programs are so hard to find. When a program’s price is not published anywhere, that is a disclosure gap, not evidence that the price is low.
Whether the medication is inside the bundle
Medicare’s opioid treatment program rates show how much this matters. The weekly methadone bundle is $277.29 and the weekly oral buprenorphine bundle is $296.57, but the monthly injectable buprenorphine bundle is $2,063.77 because the drug component alone is $1,823.20. Ask whether medication is included in a quoted rate or billed separately. Our guides to Suboxone costs and Narcan costs cover the pharmacy side in detail.
Amenities, and what “luxury” actually buys
Private rooms, small census, chef-prepared food, gyms and scenic locations are real costs, and they are hotel costs. The clinical services underneath (withdrawal management, counseling, medication management, toxicology testing) are the same services state Medicaid programs pay a few hundred dollars a day for. Luxury pricing is not evidence of better clinical care, and a program unwilling to put a per-day rate and an inclusion list in writing is telling you something.
Cash Price vs. Insurance
Behavioral health is one of the few areas where the published cash price can be higher than every negotiated rate on the same line. In Palo Verde’s file, the $2,150 inpatient cash price sits above every payer rate on that line, including a Medicare Advantage rate of $919.95 and a payer spread running $889 to $1,480. At Physicians Behavioral Hospital, the $1,200 cash price sits above a payer range of $737.63 to $1,245.
The practical reading is that self-pay is a starting number, not a final one, and there is documented room between it and what insurers pay. If you are paying cash at a hospital-licensed program, ask for the rate to be brought toward the payer range and ask for the financial assistance application in the same conversation.
Coverage matters here more than in most categories. Medicaid is accepted by 77.8% of substance use treatment facilities and cash or self-payment by 89.9%, according to SAMHSA’s 2024 facility survey. If you are uninsured and income-eligible, enrolling in Medicaid is usually the highest-value single step available, and it is not a slow process in most states when treatment is urgent.
Free and State-Funded Treatment
This is the part the advertising leaves out. SAMHSA’s 2024 National Substance Use and Mental Health Services Survey found that 46.3% of substance use treatment facilities, 7,383 of them, offered treatment at no charge or at minimal payment to clients who could not afford to pay. That share has held between 45% and 46% every year since 2021.
The money behind much of that is the federal block grant. On February 4, 2026, SAMHSA announced its first FY2026 allocation of $475 million through the Substance Use Prevention, Treatment, and Recovery Services block grant, plus $319 million through the Community Mental Health Services block grant, distributed to all 50 states, D.C. and the territories. States pass that money to local providers, which is how state-funded beds and sliding-scale slots get paid for.
To reach them, call SAMHSA’s National Helpline at 1-800-662-HELP (4357). It is free, confidential and staffed 24 hours a day. SAMHSA states plainly that if you have no insurance or are underinsured, the helpline will refer you to your state office, which is responsible for state-funded treatment programs, and can often refer you to facilities that charge on a sliding fee scale. FindTreatment.gov is the online version of the same routing.
How to Pay Less
Start with the free routing before you start shopping. The helpline and FindTreatment.gov reach the state-funded system that commercial search results do not surface. Waiting lists exist, but so do openings, and ambulatory levels of care usually have shorter ones.
Ask every program for a written per-day rate and an inclusion list. Specifically: is withdrawal management included, is medication included, is the psychiatric evaluation included, is toxicology testing included. Compare that number against the benchmarks in the table above using our fair price checker.
Price the medication route separately. Medication treatment for opioid use disorder is delivered in offices, clinics and by telehealth, and prices in the hundreds of dollars a week rather than the thousands. Our Suboxone cost guide covers the prescription path, and Narcan costs covers overdose reversal, which many programs now supply at no charge.
Use sliding-scale and federally funded clinics for the outpatient portion. Counseling, medication management and IOP are frequently available on an income-based scale. Our free clinics and sliding-scale guide explains how to find them, and our therapy cost guide and psychiatrist cost guide cover the ongoing care that follows a program.
Apply for charity care at any hospital-licensed program. Nonprofit hospitals are required to have written financial assistance policies, and behavioral health admissions qualify like any other. Start with our hospital charity care guide and the charity care checker.
If a bill has already landed, get it itemized and then negotiate. Per diem billing errors (extra days, duplicated levels of care) are common in this category. Use our itemized hospital bill guide to get the line detail, then work the balance down with our medical bill negotiation guide and, if it has already gone to collections, our medical bills in collections guide.
The Bottom Line
Expect roughly $478 to $2,150 a day for medical detox, about $9,200 to $11,700 for a 30-day residential program at documented state rates, and $319 to $1,250 a day for structured day programs. Expect medication treatment for opioid use disorder to cost a fraction of any of that. And expect that nearly half of the treatment facilities in the country report serving people who cannot pay, which means the first phone call should be to the free routing service rather than to the program with the best search ranking.
None of this is a recommendation about which level of care you need, and cost should not be the reason to step down from a level a clinician recommends. It is a set of benchmarks so that when a program names a price, you know whether it is inside the range that documented payers actually pay.
