Drug and Alcohol Rehabs in Union, MO
Union is the seat of Franklin County, an hour southwest of St. Louis where the outer suburbs give way to the Ozark foothills.
The county was settled by German immigrants from the 1830s, and Washington a few miles north was for a century the largest producer of corncob pipes in the world.
Franklin County has grown as the St. Louis metro has spread west along Interstate 44.
Franklin County has recorded a substantial decline in overdose deaths, from 47 in the twelve months to December 2021 to 27 in the twelve months to December 2025 on provisional CDC counts, a fall of 43 percent.
The treatment picture is thin locally. Around eight facilities sit within twelve miles of Union, three of which indicate intensive outpatient and five offer medication-assisted treatment.
None indicates detox or residential care within twelve miles.
Widening to thirty miles reaches twenty-seven facilities including two with detox and three beds, as the ring stretches toward the St. Louis metro.
Five maintenance providers locally is the strongest part of the picture and sits behind a good deal of that improvement.
Which Level of Care Do You Need
The figures below use a twelve-mile catchment with wider numbers where they change the picture, covering Downtown Union MO, Washington and Sullivan.
Medically Supervised Detox
Detox means riding out withdrawal with clinical staff watching, usually across three to seven days for alcohol and five to ten for opioids. Nothing within twelve miles of Union indicates detox provision, and around two do within thirty. Those sit toward the St. Louis metro, around forty minutes northeast, so the practical position is better than the local count suggests.
Inpatient Residential Treatment
Residential care puts someone in a live-in setting for weeks at a time, with therapy and daily routine running together. Nothing within twelve miles indicates residential provision, and around three do within thirty. Because detox sits outside the local ring and usually has to come first, arranging the two together is worth doing rather than separately.
Outpatient, IOP and PHP Treatment
Because Missouri assesses against ASAM criteria, the level you are placed at is a clinical finding rather than a sales category, and it is worth asking to see it. Around eight providers within twelve miles offer outpatient services, three indicate intensive outpatient and five medication-assisted treatment, rising to twenty-six and eight within thirty with fifteen offering maintenance treatment. Three intensive outpatient programs and five maintenance providers together make an ongoing plan workable without leaving the county.
Dual Diagnosis and Co-Occurring Disorders Treatment
Around half of people with a substance use disorder also have a diagnosable mental health condition, and treating one while leaving the other alone rarely holds. Around three providers within twelve miles of Union indicate this work, rising to about twelve within thirty. If a mental health condition is part of the picture, expect an integrated placement to sit toward the St. Louis metro.
Sober Living Homes and Transitional Living
Transitional and sober living housing sits outside this directory. Standards in Missouri come through the Missouri Coalition of Recovery Support Providers, the state’s National Alliance for Recovery Residences affiliate. Since certification is optional, ask a residence directly whether it holds it and who inspects it. Housing costs in Franklin County sit below the St. Louis metro, which makes recovery housing more achievable here.
Addiction Treatment Cost and Insurance Coverage in Union, MO
Franklin County prices below the St. Louis metro while sitting within reach of it, and with CSTAR and PR+ both available the publicly funded route reaches further than the private market does.
How Much Does Addiction Rehab Cost?
Standard outpatient care in Union costs roughly $1,300 to $5,200 a month and is well supplied locally, alongside intensive outpatient at $2,700 to $9,200 a month and medication-assisted treatment. Residential treatment at $6,200 to $26,000 a month and medical detox at $1,500 to $5,000 a week both mean the drive toward St. Louis.
Because the local strength is intensive outpatient and maintenance treatment together, establishing whether that combination would meet the clinical need is worth doing before committing to a bed an hour away.
| Level of care | Monthly | Daily |
|---|---|---|
| Medical detox (7–14 days) | $1,500 – $5,000 per week | $215 – $715 |
| Residential inpatient | $6,200 – $26,000 | $205 – $865 |
| PHP | $7,200 – $14,000 | $240 – $465 |
| IOP | $2,700 – $9,200 | $90 – $305 |
| Outpatient | $1,300 – $5,200 | $43 – $172 |
| Level of care | Monthly | Daily |
|---|---|---|
| Residential inpatient | $18,000 – $52,000+ | $600 – $1,730 |
| PHP | $14,500 – $33,000 | $485 – $1,100 |
| IOP | $10,000 – $25,000 | $335 – $835 |
| Outpatient | $5,200 – $16,000 | $175 – $535 |
Does Insurance Cover Rehab?
Yes. Addiction treatment sits among the essential health benefits most plans are required to include. What a plan actually pays varies with the employer, the network and the level of care, so two people with the same insurer can face very different bills. Employer plans, Medicare and MO HealthNet are all common here.
Being insured settles less than people expect. Prior authorization applies to detox and residential admission, and the network question decides the cost. Anyone commuting into St. Louis for work should know that treatment at the far end of that existing drive is frequently more practical than it first appears.
Free and State-Funded Addiction Rehab in Union, MO
Missouri funds addiction treatment through CSTAR, the Comprehensive Substance Treatment and Rehabilitation program, which covers a full continuum from outpatient through residential care and includes temporary living arrangements where they are needed. Four specialised versions exist, including one designed for women and their children. If you do not have Medicaid, ask about PR+, which is modelled on CSTAR and built specifically for people without coverage. That distinction is the single most useful thing to know before ringing round programs here.
Missouri also runs one of the largest Certified Community Behavioral Health Clinic networks in the country, with around twenty CCBHCs between them covering all 114 counties and the city of St. Louis. A CCBHC is required to serve anyone who asks regardless of ability to pay or where they live, and Missouri expanded Medicaid in 2021, so a good number of adults who assumed they did not qualify now do.
