TRUSTED CONTENTAddiction treatment in Missouri costs roughly $40 to $830 a day before insurance, with weekly outpatient counseling at the low end and residential care at the high end. Missouri programs quoted RehabSeekers.com $6,000–$25,000 for a month of residential rehab, $220–$700 a day for medical detox, $7,000–$13,000 a month for partial hospitalization (PHP), $2,500–$9,000 for intensive outpatient (IOP) and $1,200–$5,000 for standard outpatient care.
Our own data: RehabSeekers.com commissioned a team of researchers to phone treatment programs in Missouri, across several cities, and in every other state, recording the self-pay prices they quoted for 2027. MO HealthNet, a state-regulated health plan or Division of Behavioral Health funding can bring your share far below these figures. Read our method.

Residential care costs the most because it includes a bed, meals and round-the-clock staff; the top Missouri quote reached $830 a day.
Is rehab in Missouri cheaper than in other states?
Somewhat. Missouri’s typical residential price of $15,500 a month is below the U.S. median of $16,500, and 29 states charge more. On residential care, its eight neighbors split this way: Kansas, Oklahoma and Arkansas are cheaper; Iowa, Kentucky and Nebraska match Missouri; Illinois and Tennessee cost more.
Missouri against the rest of the country
- Missouri is a slightly lower-cost state for most kinds of rehab. A typical month of residential care costs $15,500, 6% below the U.S. median; 29 states charge more and 7 charge less.
- Medical detox, residential, PHP and IOP come in under the median. The widest gap is for PHP, at 7% below the U.S. median.
- Standard outpatient matches the national median at $3,100 a month, so here a Missouri quote looks like most of the country.
- How the eight neighbors line up. For residential care, Kansas, Oklahoma and Arkansas are cheaper; Iowa, Kentucky and Nebraska match Missouri; Illinois and Tennessee cost more. Arkansas and Oklahoma tie for the lowest price on the map, $2,000 a month less than in Missouri.
| Level of care | Typical price | vs. U.S. median | Rank among 50 states | Cheapest neighbor |
|---|---|---|---|---|
| Medical detox | $460 a day | 3% below the U.S. median | 28 states cost more, 8 cost less, 13 the same | Arkansas, Kansas and Oklahoma (tied), $400 a day ($60 less) |

Three of Missouri’s neighbors (Iowa, Kentucky and Nebraska) have the same typical residential price as Missouri. That is a finding in itself: here, your program and how you pay shape the bill more than the state line does. Typical detox is $460 a day in Missouri, Tennessee, Iowa, Kentucky and Nebraska. Public funding in Missouri flows to Missouri providers, so check coverage before you choose a program in Arkansas or anywhere else.
What does Missouri law make health insurers offer for addiction treatment?
Missouri requires insurers to offer chemical dependency coverage with day minimums for detox, residential and outpatient care. It is a required offer, not a required benefit: the group or individual policyholder, often an employer, can accept or reject it.
| Service | Minimum per benefit period | Missouri self-pay value |
|---|---|---|
| Detoxification (medical or social setting) | At least 6 days | $1,320–$4,200 for 6 days |
| Residential treatment | At least 21 days | $4,200–$17,500 for 21 days, prorated from the monthly price |
| Outpatient, including partial- or full-day programs | At least 26 days of treatment | Counted in treatment days; 26 days of weekly counseling would span several months, so a calendar-day price does not apply |
| Medication-assisted treatment | Must be included | Not priced in our survey |
Coverage minimums: Revised Statutes of Missouri § 376.811. Prices: RehabSeekers.com Rehab Cost Survey, 2027, before insurance.
- Same cost-sharing as physical illness. When the coverage is included, it carries the same coinsurance, copayments and deductibles that apply to physical illness. A lifetime cap of no fewer than 10 treatment episodes is allowed, but not for medical detox in a life-threatening situation.
- Parity for mental health conditions. Under RSMo 376.1550, insured plans cannot put a greater financial burden on mental health treatment than on physical health treatment, and deductibles and out-of-pocket limits must count care for all conditions together. Individually underwritten plans are excluded.
- Insured plans only. These state rules apply to insured plans regulated in Missouri; self-funded employer plans follow federal law instead.
Addiction medications without prior authorization
Since 2019, Missouri law (RSMo 191.1165) has required health insurance plans delivered in the state (not self-funded employer plans) to include buprenorphine, methadone, naloxone, naltrexone and buprenorphine/naloxone, without prior authorization, without annual or lifetime dollar limits and without step therapy that conflicts with a prescriber’s treatment plan. These medications must also sit on the lowest cost-sharing tier of the plan’s formulary. MO HealthNet must cover these medications and services too.

How much does medical detox cost in Missouri?
Missouri programs quoted $220–$700 a day for medical detox, so ten days can reach $2,200–$7,000. Missouri’s insurance offer sets a minimum of 6 detox days per benefit period, worth $1,320–$4,200 at self-pay prices.
| Detox length | Estimated total before insurance |
|---|---|
| 3 days | $660–$2,100 |
| 5 days | $1,100–$3,500 |
| 7 days | $1,540–$4,900 |
| 10 days | $2,200–$7,000 |
Detox is most important for alcohol, opioid and benzodiazepine withdrawal. DBH’s CSTAR Opioid programs pair supervised withdrawal with ongoing medication-assisted care.
How much do 30, 60 and 90 days of residential rehab cost in Missouri?
Self-pay residential care in Missouri costs $6,000–$25,000 for 30 days and $18,000–$75,000 for 90 days. MO HealthNet’s federal waiver sets a goal of a 30-day statewide average stay in residential treatment; that is a target for the program as a whole, not a cap on any one person’s stay.
| Length of stay | Estimated total before insurance | Good to know |
|---|---|---|
| 30 days | $6,000–$25,000 | Short-term stay; most people step down to PHP or IOP next |
| 60 days | $12,000–$50,000 | Allows more practice of relapse-prevention skills |
| 90 days | $18,000–$75,000 | NIDA says most individuals need at least 3 months of treatment |
What a step-down plan adds up to
Detox, then residential care, then PHP and IOP totals $19,540–$60,900 in Missouri before insurance. Each step after residential care costs less per day, so a clinically appropriate earlier step-down lowers the total. See PHP and IOP programs.
| Stage | Length | Estimated cost before insurance |
|---|---|---|
| Medical detox | 7 days | $1,540–$4,900 |
| Residential treatment | 30 days | $6,000–$25,000 |
| Partial hospitalization | 30 days | $7,000–$13,000 |
| Intensive outpatient | 60 days | $5,000–$18,000 |
| Full course of care | 127 days | $19,540–$60,900 |

Select a level of care and move the slider to the number of days you have in mind. For detox, the tool multiplies the Missouri daily quote (up to 14 days). For residential, PHP, IOP and outpatient care, it takes the Missouri monthly quote and prorates it to the days you choose.
These are estimates before insurance; your program’s quote may differ.
Does MO HealthNet (Missouri Medicaid) pay for rehab?
Yes. MO HealthNet is Missouri’s Medicaid program, and its managed care plans list behavioral health and substance use services among the benefits every plan must offer. For members, MO HealthNet usually costs far less than any self-pay price on this page.
- Expansion is in the state constitution. Missouri voters added Medicaid expansion to the constitution. Beginning July 1, 2021, adults ages 19 to 64 with income at or below 133% of the federal poverty level qualify. The same section bars extra eligibility or enrollment burdens on this group.
- Residential treatment in larger facilities. CMS approved Missouri’s Substance Use Disorder and Serious Mental Illness demonstration on December 6, 2023. Through December 31, 2028, it lets MO HealthNet pay for medically necessary residential treatment in facilities classed as institutions for mental disease (IMDs), for full-benefit members ages 12 to 64.
- Three plans plus a children’s plan. Managed care members are served by Healthy Blue, Home State Health or UnitedHealthcare. Show Me Healthy Kids, managed by Home State Health, covers certain children and former foster youth.
- Medication for addiction. State law requires MO HealthNet to cover buprenorphine, methadone, naloxone, naltrexone and the buprenorphine/naloxone combination.
- Copays. Missouri rescinded its rule on Medicaid copayments and coinsurance in March 2022 and its pharmacy copay rule in November 2022. Confirm with your plan before treatment starts.
- Applying. You can apply online through the myDSS portal, by phone, or with a paper application.
Federal work requirements for expansion adults, which states must put in place by January 1, 2027, exclude people in certain drug or alcohol treatment programs and treat people with a substance use disorder as medically frail. Keep answering renewal notices during treatment. Find rehabs that accept Medicaid.
How do you get state-funded rehab in Missouri?
Through the Missouri Department of Mental Health’s Division of Behavioral Health (DBH). DBH contracts with community organizations to deliver most services, and not every provider has a contract, so ask a program whether it takes state funding.
- CSTAR programs. Comprehensive Substance Treatment and Rehabilitation programs come in four tracks: General Population (intensive outpatient and a full range of services), Women and Children, Adolescent (ages 12 to 17) and Opioid (medication-assisted withdrawal followed by ongoing treatment).
- Primary Recovery Plus. Modeled on CSTAR General Population, it offers a full continuum of services for people without Medicaid coverage.
- Detox and residential support. DBH-funded detoxification and residential support are offered for people who need a safe, substance-free setting during treatment.
- What you pay. DBH says the cost of services is based on a person’s ability to pay. State law (RSMo 630.210) requires a standard means test for department charges.
- Who goes first. Pregnant women, people who inject drugs and certain referrals from other state agencies get first priority. CSTAR Opioid programs also prioritize people who are HIV positive.
Missouri also has 18 Certified Community Behavioral Health Clinics serving all 114 counties, part of a federal demonstration that began in Missouri on July 1, 2017. People ordered into the Substance Awareness Traffic Offender Program (SATOP) after a DWI attend DBH-certified programs; part of the SATOP supplemental fee pays for financial help for eligible participants under a standard means test. Our directory lists state-funded programs alongside private centers.

How many Missourians need addiction treatment?
SAMHSA estimates that 1,016,000 Missourians age 12 and older, or 19.39%, had a past-year substance use disorder (2023–2024 average). In 2024, 79.36% of Missourians classified as needing substance use treatment, about 794,000 people, did not receive it.
The Missouri Department of Health and Senior Services counted an all-time high of 2,180 overdose deaths in 2022 and 1,948 in 2023. CDC data put Missouri’s 2024 age-adjusted drug overdose death rate at 23.7 per 100,000. The state counts and the CDC rate measure different things and are not directly comparable. In June 2026, the department said deaths had fallen for three consecutive years, with accidental drug poisonings down 17.4% in 2025; it did not publish a 2025 total in that release.
How we collected Missouri rehab prices
RehabSeekers.com commissioned a team of researchers who telephoned at least five treatment centers in each state, in more than one city, and asked for the self-pay price of each level of care. Missouri ranges run from the lowest to the highest quote Missouri centers gave.
- Prices and timing: quotes for admission in early 2027, gathered by phone from October 2026 through January 2027, not copied from other websites.
- Totals: detox multiplies the daily price; residential, PHP, IOP and outpatient totals prorate the monthly price by day.
- Coverage and health facts come from the Missouri Constitution and Revised Statutes, the Departments of Social Services, Mental Health and Health and Senior Services, CMS, SAMHSA, the CDC and NIDA, listed under Sources.

Do Missouri insurers have to cover rehab?
Insurers must offer chemical dependency coverage with minimums of 6 detox days, 21 residential days and 26 outpatient days per benefit period, at the same cost-sharing as physical illness.

Does my insurance need prior authorization for Suboxone or methadone in Missouri?
Not for the medications Missouri law lists. Under RSMo 191.1165, health insurance plans delivered in Missouri (not self-funded employer plans) cannot require prior authorization or annual or lifetime dollar limits for buprenorphine, methadone, naloxone, naltrexone or buprenorphine/naloxone, and MO HealthNet must cover them.
