Intensive Outpatient Program (IOP) for Addiction
Flexible, Evidence-Based Addiction Treatment While You Continue Your Daily Life
Kolmac’s intensive outpatient program allows you to receive structured addiction treatment without stepping away from work, school, or family. IOP provides professional clinical care for alcohol use disorder, drug addiction, and gambling addiction through group therapy, individual counseling, psychiatric services, and medication management, all while you live at home.
Fifty years ago, Kolmac introduced one of the first intensive outpatient programs in the country because we understood that inpatient rehab was not the right fit for everyone. That same philosophy drives our program today: effective, accessible treatment that meets you where you are.
IOP is available at all Kolmac locations across Maryland, Virginia, Washington, D.C., and Pennsylvania, including in-person, virtual, and hybrid options. Call (888) 521-7692 or request an appointment to get started within one business day.
What Is an Intensive Outpatient Program?
An intensive outpatient program (IOP) is a structured level of addiction treatment that provides several hours of therapy per week without requiring you to live at a treatment facility. IOP falls between a partial hospitalization program (PHP) and standard outpatient care on the continuum of treatment.
IOP is recognized by insurance providers and the American Society of Addiction Medicine (ASAM) as an appropriate level of care for individuals who need consistent clinical support but have enough stability to manage daily responsibilities outside of treatment. Research consistently shows that intensive outpatient treatment is as effective as inpatient rehab for many patients.
At Kolmac, IOP combines group therapy, individual counseling, psychiatric services, medication-assisted treatment (MAT), and family participation into a single, integrated treatment plan.

Three Phases of Kolmac IOP Treatment
Kolmac’s intensive outpatient program follows a structured, three-phase approach that ensures a smooth transition from stabilization through long-term recovery support.
Phase 1: Detoxification. For patients who need medically supervised withdrawal management, Kolmac offers virtual, home-based detox. Our medical team monitors you throughout the process, adjusting medications as needed to keep you safe and comfortable before you begin IOP.
Phase 2: Intensive Outpatient Program (IOP). The core treatment phase combines group therapy, individual counseling, psychiatric services, and skill-building. This is where the daily work of recovery happens while you continue living at home and maintaining your responsibilities.
Phase 3: Outpatient and Continuing Care. After stabilization, patients step down to a less intensive outpatient schedule that includes group sessions, individual therapy, family participation, and ongoing medical support. Patients can participate in continuing care in-person, fully virtual, or in a hybrid format.
Our clinical team ensures consistency across all three phases so you never feel like you are starting over.

Who Is IOP Right For?
Kolmac’s intensive outpatient program is appropriate for individuals who:
- Have a stable and supportive home environment
- Need structured treatment but can manage daily responsibilities alongside care
- Are stepping down from a partial hospitalization program (PHP) or inpatient rehab
- Prefer to continue working, attending school, or caregiving during treatment
- Are committed to long-term recovery and ready to engage in group-based treatment
If you are unsure whether IOP is the right level of care, Kolmac’s clinical team will determine the appropriate placement through an initial evaluation. Some patients begin in PHP and transition to IOP as they stabilize, while others enter IOP directly.
Family Participation
Addiction affects the whole family, and recovery is stronger when families are involved. Kolmac offers weekly family group sessions (all virtual, three options per week) where loved ones can learn about addiction, understand the recovery process, and build healthier communication patterns.
We also encourage participation in community support groups such as Al-Anon, Nar-Anon, Alcoholics Anonymous, Narcotics Anonymous, and SMART Recovery Family and Friends.
IOP vs. PHP: Choosing the Right Level of Care
The main difference between an intensive outpatient program and a partial hospitalization program is the number of hours per week.
IOP involves 3 hours per day, 4 days per week (12 hours/week). It is appropriate for patients who have enough stability to manage daily responsibilities alongside treatment, are stepping down from PHP, or are entering treatment for the first time with a supportive home environment.
PHP involves 6 hours per day, 5 days per week (30 hours/week). It is appropriate for patients who need a higher level of structure, are earlier in their recovery, or have co-occurring mental health conditions that require close monitoring.
At Kolmac, many patients begin in PHP and transition to IOP as they stabilize. Our clinical team determines the appropriate level of care through an initial evaluation.
Virtual IOP and Telehealth Options
In addition to in-person IOP at all Kolmac locations, we offer virtual IOP through secure telehealth. Virtual IOP is available across Pennsylvania, Maryland, Virginia, and Washington, D.C., and provides the same evidence-based treatment as our in-person program.
Virtual IOP is ideal for patients who live farther from a Kolmac location, have transportation barriers, or prefer the convenience of attending sessions from home.

Continuing Care After IOP
After you stabilize in recovery, you can step down to our outpatient program, which includes group treatment, individual therapy, family participation, medical support, and MAT/Suboxone management. Patients can participate in continuing care in-person, fully virtual, or in a hybrid format depending on need and preference.
Why Group Therapy Works
Group therapy is the backbone of Kolmac’s intensive outpatient program. We evolved in groups, and we recover best in groups. When individuals isolate themselves and refuse to allow others to help, they often resort to negative coping mechanisms. Group therapy keeps patients connected to peers who understand what they are going through, which is essential for lasting recovery.
Evidence-based benefits of group therapy include:
- Structure and peer support to sustain recovery after the initial treatment phase
- Connection and community to reduce loneliness and isolation
- Inspiration from hearing the experiences of peers in recovery
- Opportunities to learn, develop, and practice healthy coping strategies
- Knowledge about the neurobiological, social, and psychological components of addiction
Therapeutic approaches used in Kolmac IOP groups include cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), acceptance and commitment therapy (ACT), and relapse prevention. Sessions also cover anger management, stress management, nutrition and healthy lifestyle, meditation and mindfulness, healthy relationships, and setting boundaries.
Frequently Asked Questions About Intensive Outpatient Programs
How long does an intensive outpatient program last?
The length of IOP varies by individual need. Most patients participate in IOP for 8 to 12 weeks, though some may need more or less time depending on their progress. After completing IOP, patients typically step down to standard outpatient care and continuing care programming.
Can I work while attending IOP?
Yes. Kolmac’s IOP is specifically designed to allow you to continue working, attending school, or managing family responsibilities. Sessions are scheduled during blocks of the day that accommodate most work schedules, and some locations offer weekend options.
Does insurance cover intensive outpatient treatment?
Yes. Most major insurance plans cover IOP as a recognized level of addiction treatment. Kolmac’s admissions team will verify your benefits and explain any out-of-pocket costs before you begin. Contact us at (888) 521-7692 to check your insurance coverage.
What is the difference between IOP and regular outpatient therapy?
IOP is more structured and intensive than standard outpatient therapy. While regular outpatient might involve one session per week, IOP includes 3 hours of treatment, 4 days per week, combining group therapy, individual counseling, and medical support. IOP provides a higher level of accountability and clinical oversight.
Do you treat co-occurring mental health conditions during IOP?
Yes. Kolmac integrates psychiatric services into IOP to address co-occurring conditions such as depression, anxiety, trauma, and mood disorders. Our clinical team treats addiction and mental health together rather than separately. For standalone mental health treatment, our Mental Health IOP may be a better fit.
Is medication-assisted treatment (MAT) available during IOP?
Yes. Kolmac offers MAT including Suboxone and other FDA-approved medications for opioid and alcohol use disorders. A psychiatrist prescribes and monitors medication, with support from a Psychiatric Nurse Practitioner.
How quickly can I start IOP?
Kolmac’s streamlined admissions process allows most patients to start treatment within one business day. Call (888) 521-7692 or request an appointment online to begin.
What happens if I need a higher level of care than IOP?
If our clinical team determines that you need more intensive support, you may be placed in Kolmac’s partial hospitalization program (PHP), which provides 6 hours of treatment per day, 5 days per week. Patients can transition between levels of care as their needs change.
