Choosing a Denver intensive outpatient program (IOP) comes down to three things: whether you can safely live at home during treatment, how many clinical hours a week you actually need, and whether the program takes your coverage. If you already know IOP is the right fit, the fastest way to find out what you would pay is to verify your insurance benefits before you compare schedules.
TL;DR IOP is the right level of care when home is safe and withdrawal is not. If either of those is shaky, start higher and step down. Coverage, not clinical fit, is what stalls most Denver enrollments, so check benefits first.
Key Takeaways
- IOP means roughly 9 to 19 clinical hours a week while you live at home, per the ASAM Criteria that Colorado uses to determine level of care.
- Home stability decides the level of care. Active withdrawal risk, uncontrolled psychiatric symptoms, or unsafe housing point to detox or residential care first.
- Colorado Medicaid covers the full substance use continuum, including intensive outpatient, though each managed care organization applies its own review rules.
- Evening programming is what makes IOP work for people holding a job or caring for family. Confirm the actual days and times before you enroll.
- If you are medically stable and home is safe, choose IOP. If withdrawal or psychiatric symptoms are active, choose detox or residential first and treat IOP as the step-down.
Is IOP the right level of care for you?
IOP fits adults who need structured, frequent clinical contact but do not need 24-hour medical supervision. You attend group and individual sessions several days a week, sleep at home, and keep working or caring for family in between.
Three conditions usually need to be true:
- You can stop or reduce use without medically supervised withdrawal.
- You have somewhere safe and reasonably substance-free to sleep.
- You can reliably get to sessions, in person or by video.
If all three hold, IOP gives you real clinical intensity without stepping out of your life. If any one of them is shaky, a higher level of care is the safer starting point, and IOP becomes the step-down after you stabilize.
Signs you need a higher level of care first
Some symptoms are not a judgment call. Talk to a clinician about medically supervised detox or residential addiction treatment if any of these apply:
- Withdrawal symptoms such as severe tremor, vomiting, rapid heart rate, confusion, or seizures, particularly when stopping alcohol or benzodiazepines.
- Suicidal thoughts, a plan, or recent self-injury.
- Hallucinations, disorganized thinking, or mania that impairs decision-making.
- Repeated overdoses, or relapse within days despite outpatient attendance.
- No safe place to sleep, or a home where others are actively using.
If someone is in immediate danger, call 911 or go to the nearest emergency department. For a mental health or substance use crisis that is not immediately life-threatening, call or text 988.
IOP compared with detox, residential, and inpatient care
The differences that matter are supervision, where you sleep, and how quickly the program can respond if you become medically unstable.
| Intensive outpatient (IOP) | Residential (ASAM 3.5) | Inpatient | Medically supervised detox (ASAM 3.7) | |
|---|---|---|---|---|
| Clinical intensity | Roughly 9 to 19 hours a week | Structured programming across the full day | Structured programming with medical oversight | Continuous monitoring through acute withdrawal |
| Where you sleep | At home or in recovery-supportive housing | On site | On site | On site, in a medical setting |
| Medical oversight | Scheduled clinical contact, not around the clock | On-site staffing day and night | On-site medical and clinical staffing | Nursing and medical management of withdrawal |
| Typical length | Weeks, varies with clinical need | Weeks, varies with clinical need | Varies with clinical need | Short, based on withdrawal course |
| Who it suits | Medically stable adults with stable housing | Adults needing daily structure away from triggers | Adults needing integrated medical and psychiatric care | Adults with active or risky withdrawal |
| Keeps work and family routines | Yes, especially with evening sessions | No, you stay on site | No, you stay on site | No, you stay on site |
Movement between these levels is normal and expected. Many people enter at detox, step to residential or inpatient treatment, then finish in IOP. Others start in IOP and step up if symptoms escalate.
A note on the numbers: the ASAM Criteria Fourth Edition, which Colorado’s Medicaid agency publishes for providers, defines Level 2.1 intensive outpatient as 9 to 19 hours of clinical services per week and folds withdrawal management into the x.7 levels of care (Colorado Department of Health Care Policy & Financing).
Ask about partial hospitalization separately
Some Denver providers offer a partial hospitalization program (PHP), a near-daily day program that sits between IOP and residential care. Programs vary in whether they run one, so ask directly rather than assuming a provider offers every level.
What a Denver IOP week actually looks like
A realistic IOP week is built around group therapy, with individual sessions layered in. Ask any program you are considering for the exact days, times, and format before you commit, because a schedule that collides with your shift or your childcare is the most common reason people drop out.
Foundry’s Denver IOP runs on this structure:
- Three structured group sessions a week, three hours each, from 6:00 to 9:00 PM
- Individual counseling with a licensed professional counselor or clinical social worker
- Individual recovery coaching with a certified addiction specialist
- Typically one individual session a week with a counselor or recovery coach
Our clinicians work in DBT, CBT, motivational interviewing, schema work, trauma therapies, and Gestalt approaches, and family programming is built into the program rather than sold separately. Care is delivered in person at our outpatient location at 3254 Larimer St. in Denver, or through virtual IOP by secure telehealth if getting to Larimer Street three evenings a week is not realistic.
Full program details, including what each group covers, are on our Denver intensive outpatient program page.
Medication and co-occurring conditions
Ask every program two questions about medication: who prescribes, and how follow-up is handled between sessions. Programs differ widely, and a gap in prescribing is a common failure point when someone moves between levels of care.
Co-occurring anxiety, depression, PTSD, and other mental health conditions are the norm rather than the exception in addiction treatment, so ask how a program treats both at once instead of treating them in sequence. Our own approach to co-occurring and dual-diagnosis care uses the Trauma-Integrated Care model developed by Dr. Michael Barnes, which addresses unresolved trauma alongside substance use.
Does Colorado Medicaid cover intensive outpatient treatment?
Yes. Health First Colorado, the state’s Medicaid program, covers the full substance use disorder continuum, including withdrawal management, inpatient, residential, intensive outpatient, medication-assisted treatment, and outpatient services (Colorado Department of Health Care Policy & Financing).
Coverage existing and coverage being approved for you are different questions. Each regional managed care organization applies its own documentation and review requirements, so what a specific program will cost you depends on your plan and your clinical assessment.
What to have ready when you call about coverage:
- Your full name, date of birth, and Medicaid member ID
- The name of your plan and your regional organization
- The program name and location you are asking about
- A note of who you spoke with and when
Foundry’s outpatient program is in-network with Aetna, Blue Cross Blue Shield, Cigna, Rocky Mountain Health, and UnitedHealthcare, and accepts RAE 1 and RAE 2 Medicaid. We work with most major insurance plans, and on an out-of-network basis where that makes sense. If Medicaid is how you are paying, our Medicaid rehab program page covers how coverage works across our levels of care.
How to vet a Denver IOP provider
Program pages tend to describe intentions. A phone call surfaces how a program actually runs. Work through these seven questions with every provider on your list.
- Is the program licensed in Colorado, and is it accredited? Ask for the license and any national accreditation, such as The Joint Commission.
- Who performs the clinical assessment, and how often is it revisited? A program using ASAM criteria should be able to explain why IOP fits you, and what would trigger a change.
- How is medication handled? On site, or coordinated with an outside prescriber, and who manages follow-up.
- Who runs the groups? Ask for clinician licensure types, group size, and who supervises clinically.
- Are co-occurring mental health conditions treated in the same program? Being sent between two providers for one problem adds friction at the worst time.
- What are the real days and times? Confirm evening or daytime availability, attendance policy, and whether virtual sessions are an option.
- What will this cost with my coverage? Ask for a benefits check in writing.
Red flags worth walking away from
- No verifiable Colorado licensure
- No documented assessment process beyond a single intake call
- No prescriber available when medication is clinically indicated
- Group sizes the program will not disclose
- Pressure to sign a long contract or pay cash for services that are not itemized
- Refusal to name clinical staff or describe their credentials
You can review our clinical team and their credentials as a benchmark for the level of detail a program should be willing to share.
How to start IOP at Foundry
- Call or submit a benefits check. Our admissions team confirms coverage and asks about current use, recent treatment, and medications.
- Complete a clinical screening. The screening determines whether IOP is clinically appropriate, or whether detox or residential care should come first.
- Finish intake paperwork. Consents, health history, privacy notices, and any medication releases.
- Start programming. Group and individual sessions begin on the schedule set during intake.
What to bring to your first session:
- Photo ID
- Insurance or Medicaid card
- A current medication list with doses and prescribing clinician
- A discharge summary if you recently completed detox or residential treatment
- An emergency contact name and phone number
Family involvement is part of the program rather than an add-on, and our family addiction program is where partners, parents, and adult children get their own support.
If you need time off work or school, most employers accept a neutral note confirming scheduled outpatient behavioral health treatment and the days it occurs. Our admissions staff can help with the verification an employer or school requires.
Frequently asked questions
How many hours a week is an IOP?
Roughly 9 to 19 hours of clinical services a week, usually delivered across three to five days. Foundry’s Denver IOP runs three three-hour groups a week in the evening, plus individual sessions.
Can I keep working while I attend IOP?
Usually yes, which is the point of the level of care. Evening programming exists so that people can hold a job or manage childcare during the day. Confirm the exact times before you enroll.
How is IOP different from standard outpatient therapy?
Standard outpatient care is typically one session a week. IOP delivers several hours of structured group and individual therapy across multiple days, with closer clinical contact and more coordination between providers.
Can I do IOP entirely online?
Some programs offer a fully virtual track. Foundry delivers IOP through secure telehealth as well as in person, which helps if you live outside the metro area or cannot travel to sessions in the evening.
Will my employer find out I am in treatment?
Substance use treatment records carry strong federal privacy protections. Disclosure normally requires your written authorization, with narrow exceptions. Ask any program how records are stored and what a release would cover before you sign anything.
Does IOP include medication for opioid or alcohol use disorder?
It can, though availability differs by program. Ask whether medication is prescribed on site or coordinated with an outside prescriber, and how monitoring works between sessions.
How soon can I start IOP after detox?
Timing depends on your clinical stability at discharge and on program availability, so ask admissions directly rather than planning around a general estimate. Coordinating the handoff before discharge is what prevents a gap in care.
Is IOP as effective as residential treatment?
Neither is universally better. Outcomes track how well the level of care matches clinical severity, housing stability, and psychiatric needs, which is exactly what an ASAM-based assessment is designed to determine.
