Billings, MT Dual Diagnosis Treatment Options

If you’re reading this, something has probably already told you that treating one thing at a time isn’t working. Maybe the anxiety comes back the second the drinking stops. Maybe the depression makes staying sober feel pointless, and the using makes the depression worse. Maybe a family member has been to detox twice and still isn’t sleeping, still isn’t okay.

That pattern has a name. When a mental health condition and a substance use disorder show up in the same person at the same time, clinicians call it a co-occurring disorder, or dual diagnosis. It’s not two separate problems taking turns. It’s one situation, tangled together, where each condition pulls on the other.

Here’s what matters for you, sitting in Billings or somewhere along the Yellowstone Valley: the care model that consistently works better treats both conditions together, by one team, at the same time. SAMHSA’s clinical guidance is direct about this — integrated care is the preferred model for people with co-occurring conditions ⁴. Not one after the other. Not two clinics that occasionally trade voicemails.

This guide walks you through what integrated dual diagnosis care in the Billings region should actually include, how recent Montana Medicaid changes affect what’s covered, and how to tell a genuinely integrated program from one that just puts two services under the same roof. You don’t have to figure all of it out today.

You are not an outlier. If you’ve been carrying both a mental health condition and a substance use problem, you’re carrying something a lot of your neighbors are carrying too — quietly, often without the right kind of help.

Montana’s 2025 Uniform Reporting System data, which tracks adults served by the state’s public mental health authority, tells a clear story. Of the adults in that system, 27.2% have a co-occurring mental health and substance use disorder. Among adults with serious mental illness — the more disabling end of the spectrum, including conditions like schizophrenia, bipolar disorder, and severe major depression — 32.3% also carry a substance use diagnosis ¹. That’s roughly one in three of the sickest, most vulnerable people in the state system dealing with both fronts at once.

Those numbers describe the people who made it in the door. The public system doesn’t capture everyone. It doesn’t capture the person still holding down a job in Billings Heights who drinks after every shift to quiet the panic. It doesn’t capture the college student in the Heights or downtown who’s self-medicating undiagnosed ADHD with stimulants. So think of 27.2% as a floor, not a ceiling.

Yellowstone County concentrates a lot of Montana’s population, its hospitals, and its behavioral health infrastructure. That means the raw number of adults living with co-occurring conditions here is larger than in most Montana counties — and so is the pool of people trying to find care that treats both sides of what they’re dealing with. When a program in the region looks at its intake list and sees person after person with anxiety plus alcohol, depression plus meth, PTSD plus opioids, that’s not a coincidence. That’s the shape of the population.

What that means for you: the fact that both things are happening at once doesn’t make your case unusual or too complicated for treatment. It makes it typical. And typical is something a well-designed program should be built to handle from day one, not something bolted on later.

If the evidence is this clear, you’d think integrated care would be the default by now. It isn’t. Not nationally, and not in Montana.

A 2026 analysis of national survey data tracked how many U.S. adults with co-occurring substance use and mental illness actually received treatment for both conditions. The share climbed from 7.5% in 2021 to 16.9% in 2022 to 18.2% in 2023 ⁸. That is real movement, and it matters. It also means that in the most recent year measured, more than four out of five adults with both conditions were still not getting care for both. Most were getting nothing, or getting only one side treated.

Montana’s own data tells a companion story. The 2025 URS report shows that the state’s public mental health system, which serves the adults most in need, delivered zero measured penetration for the specific evidence-based practice called “Integrated Treatment for Co-occurring Disorders” ¹. Best practice on paper. Not yet on the ground at scale.

Why the gap? A few reasons the research keeps naming:

• Clinicians historically trained in one lane, not both.
• Reimbursement systems that paid mental health providers and substance use providers separately, which quietly incentivized separate delivery ⁵.
• Stigma and low perceived need on the client side — the same 2026 study found that fewer than 2% of untreated adults reported both perceiving a need for treatment and seeking it ⁸.

What this means for you: if the first program you call sounds fragmented, that’s the system’s default, not your fault. Keep looking. Ask the questions from the last section. The programs doing this right exist, and they’re worth finding.

Dual diagnosis care isn’t one setting. It’s a ladder, and where you start depends on how much your body and mind need holding right now. Here’s what the rungs look like in and around Yellowstone County.

Medical detox is the top rung when withdrawal is dangerous or symptoms are severe. Alcohol, benzodiazepine, and opioid withdrawal all carry medical risk that outpatient settings can’t safely absorb. For someone with untreated depression or PTSD on top of that, detox is also when psychiatric symptoms often surge — sleep is gone, the substance that was numbing everything is gone, and the underlying condition shows itself. A good detox has a prescriber who can start or adjust psychiatric medications during this window, not wait until you’re discharged.

Residential inpatient is the next step for people who need 24-hour structure. You live at the facility, usually for a few weeks, and both conditions get worked on daily. This is where the psychiatrist, therapist, and case manager should genuinely share a treatment plan rather than run parallel shifts.

Partial hospitalization (PHP) runs most of the day, five or six days a week, and you sleep at home or in supportive housing. It suits people stable enough to leave residential but still needing heavy clinical contact — a common step when psychiatric symptoms are settling but not settled.

Intensive outpatient (IOP) drops to roughly nine to twelve hours a week, usually across three days. It’s designed to fit around work or school. For dual diagnosis, look for IOPs that keep the same prescriber and therapist from higher levels of care — that continuity is where a lot of programs quietly fail ¹⁸.

Standard outpatient is weekly therapy plus medication management. It’s the long tail of treatment, and it’s where relapse prevention lives.

Wrapping around all of these: targeted case management, which under Montana Medicaid requires you to also be receiving at least one other mental health or SUD service ^{11, 12}. That coordinator is often the person who keeps the ladder from becoming a set of disconnected steps.

The money side of dual diagnosis care used to be one of the reasons integrated treatment stayed out of reach in Montana. Two conditions, two funding streams, two sets of paperwork — and the client stuck in the middle. That’s shifted in the last couple of years, and it’s worth knowing what changed, because it directly affects what a program can offer you without charging out of pocket.

On February 26, 2024, CMS approved Montana’s HEART 1115 demonstration amendment. That approval added Medicaid coverage for several services that map directly onto dual diagnosis care: contingency management (an evidence-based reward-for-abstinence approach), tenancy supports for people at risk of losing housing, reentry services for adults leaving state prisons with SUD or mental illness, and an outpatient SUD therapy package that specifically includes psychosocial rehabilitation, co-occurring mental health services, face-to-face crisis services, and face-to-face care coordination ¹⁵. That last bundle matters most for you. It means a single Medicaid-billable package can now cover the therapy, the co-occurring mental health work, the crisis response, and the coordinator keeping it all connected — under one authority, not four.

The state’s briefing to the Criminal Justice Oversight Committee confirmed the same scope and flagged the reentry piece for adults coming out of incarceration with co-occurring conditions ¹⁴.

Alongside HEART, Montana’s State Plan Amendment 23-0005 clarified coverage for behavioral and remedial services recommended by a licensed clinician ¹⁰. And the state’s targeted case management benefits — one for mental health, one for substance use disorder — both require you to also be receiving at least one other qualifying service, which is the state’s way of saying case management is meant to wrap around treatment, not stand alone ^{11, 12}.

Wanting help and getting help aren’t the same thing. If you’ve hit a wall trying to start dual diagnosis treatment, or started and dropped out, the reasons are usually not personal failure. They’re patterned, and they show up in the research.

• Stigma and low perceived need. The 2026 national analysis of adults with co-occurring conditions found that fewer than 2% of untreated adults reported both recognizing they needed treatment and actively seeking it ⁸. Some of that is the illness talking — depression tells you nothing will help, substance use tells you it’s not that bad. Some of it is watching how people around you talk about “those” people. Both are real, and neither means you’re beyond help.
• Cost and coverage confusion. Even with Montana Medicaid and HEART 1115 expansions in place, people still get turned away or hit with surprise bills because a service wasn’t authorized the way it needed to be. Ask a program to walk you through what’s covered before you commit.
• Housing and basic stability. At the Billings Crisis Care Center, 81% of clients are homeless or at risk of homelessness, and 64–72% have co-occurring disorders ²⁰. You can’t focus on therapy if you don’t know where you’re sleeping. Look for programs connected to tenancy supports, which HEART now helps fund ¹⁴.
• Feeling passed around. The systems that were built separately still act separately. If the first door you knocked on wasn’t the right one, that’s information, not a verdict. Try another.

Justice involvement changes the shape of dual diagnosis care, but it doesn’t lock you out of it. In Montana’s drug courts, roughly one-third of participants have co-occurring disorders, and more than half of admissions with reported mental health status carry a psychiatric diagnosis ⁹. If that describes you, or the person you’re trying to help, you’re in a group the system is actually paying more attention to now than it did five years ago.

Two pieces of that shift matter for Billings. First, HEART 1115 added Medicaid-funded reentry services for adults leaving state prisons with substance use or mental illness diagnoses, along with the same co-occurring mental health and crisis packages available in the community ¹⁴. That means the coverage doesn’t have to restart from zero on release day. Second, targeted case management under Montana Medicaid can wrap around court-ordered treatment, provided you’re already receiving at least one other qualifying mental health or SUD service ^{11, 12}. A case manager who knows the court calendar, the treatment plan, and the housing situation is often the person who keeps a probation status from unraveling.

Ask any program you’re considering whether they’ve worked with drug court participants, whether they can send progress documentation the court will actually accept, and how they handle a positive screen without you losing everything.

You don’t have to sort all of this out today. You have to make one call, or help someone you love make one call. That’s the whole assignment for right now.

When you make it, ask three questions:

1. Do you treat mental health and substance use together, with one team sharing a plan?
2. What do you bill under Montana Medicaid, and what do you bill under the HEART demonstration?
3. What happens if I’m not fully ready yet?

The answers will tell you a lot in about five minutes.

If the first program isn’t the right fit, that’s not the end of the search. It’s the start of a shorter one, because you now know what to listen for. Integrated care exists in the Yellowstone Valley. It’s worth the extra call to find it.

If you want a starting point that treats both conditions under one roof with a Montana-based team, Elk Ridge Recovery is one place to begin that conversation.
