Intensive Outpatient Program (IOP) in Massachusetts
An intensive outpatient program (IOP) is addiction treatment that fits around a life. At Massachusetts Center for Addiction in Quincy, IOP means about three hours of group and individual therapy a day, three to five days a week, in a morning track or an evening track, so you can keep working, going to school, or looking after your family while you get treatment. It is more support than weekly counseling and less than a full day program, and for many people it is the level of care that turns early sobriety into a routine.
This page covers what our IOP includes, the daytime and evening schedules, who it is for, how long it runs, what it costs with insurance, and how IOP compares to our partial hospitalization program (PHP) and to standard outpatient therapy. If you already know IOP is the right level, call 844-486-0671 or verify your insurance online.
What Is an Intensive Outpatient Program?
IOP is a structured treatment program you attend from home. You come in for scheduled sessions several days a week, work through a mix of group therapy, individual counseling, education, and skills practice, and spend the rest of your time living your life with the support of a clinical team you see again in a day or two. The design is deliberate: recovery skills learned in a group on Tuesday get tested at work on Wednesday and talked through on Thursday.
Some people start treatment at IOP. More often it is the second step, after detox, inpatient rehab, or PHP has handled the acute phase and the person is stable enough to hold a schedule. Either way, IOP is where the day-to-day work of staying sober gets built.
What Our IOP Includes
- Group therapy, the core of IOP, including process groups and the Little Big Book group
- Psychoeducation on addiction, relapse, stress, and the skills that hold recovery together
- Individual counseling with a primary clinician
- Cognitive behavioral therapy (CBT) and other evidence-based approaches
- Medication-assisted treatment for opioid and alcohol use disorders when appropriate
- Psychiatric services and dual diagnosis care for anxiety, depression, PTSD, and other co-occurring conditions
- Relapse-prevention planning and life-skills workshops
- Referral to sober living for clients who do not have a stable place to live
Clients commit to at least ten hours a week when they start. As recovery stabilizes, hours come down, so the program tapers toward standard outpatient rather than ending abruptly.
IOP Schedule: Daytime and Evening Tracks
We run two tracks so that treatment does not have to compete with a job. Both are three-hour sessions, three to five days a week, and both cover the same clinical program.
Daytime IOP
Morning sessions, which suit people who work afternoons or evenings, parents with school-age children, and clients stepping down from PHP who want to keep the same morning routine.
| Time (3 to 5 days a week) | Treatment group |
|---|---|
| 9:00 – 10:40 AM | Little Big Book Group |
| 10:40 AM – 12:10 PM | Psycho-Educational Group |
Evening IOP
Evening sessions three to five times a week for people who work or study during the day. The evening track includes the same evidence-based therapies, psychiatric services, and recovery-skills workshops as the daytime program. Exact times are set at intake; the schedule can shift as your needs change.
Both tracks are also available through our virtual IOP over secure video for clients who cannot get to Quincy several days a week.
Who IOP Is For
- People stepping down from PHP, inpatient rehab, or detox who are stable enough to keep a schedule but not ready to go it alone.
- People who need to keep working or studying and cannot take weeks off for a day program.
- People early in recovery who need more than weekly therapy, because once a week is not enough contact to get through cravings and bad days.
- People who have relapsed after a period of sobriety and want structure back without starting over at a residential program.
- People with a co-occurring mental health condition who need addiction treatment and psychiatric care in the same place.
Because you live at home during IOP, home needs to be safe and substance-free. If it is not, sober living alongside IOP is the usual arrangement, and admissions can set both up.
When IOP is not the right fit
IOP is not the place to start if you are in active withdrawal from alcohol, benzodiazepines, or opioids, if you need daily clinical supervision to stay safe, or if you have tried outpatient-level care recently and it has not held. In those cases detox or PHP comes first and IOP is the step-down. The clinical assessment at admission sorts this out, and if we think you need a higher level of care we will tell you and help you get there.
IOP vs. PHP
| IOP | PHP | |
|---|---|---|
| Hours | About 3 hours a day, 3 to 5 days a week (9–15 hours) | About 6 hours a day, 5 days a week (25–30 hours) |
| Work and school | Usually continues; evening track available | Usually on medical leave |
| Best for | Some stability already; building independence | Stepping down from inpatient or detox; needing daily structure |
| Clinical contact | Several sessions a week | Multiple groups every day plus individual therapy and daily check-ins |
| Focus | Practicing recovery in real life | Stabilization and deeper therapeutic work |
The two are designed to be used in sequence. Most of our PHP clients step down into IOP, and most IOP clients step down into outpatient therapy and aftercare. If you are not sure which one you need, the assessment call decides it; there is no penalty for starting at the higher level and stepping down early.
IOP vs. Standard Outpatient Therapy
Standard outpatient care is one or two sessions a week. IOP is nine or more hours a week across several days, with group work as the backbone. The difference matters most in the first few months, when the gap between a Tuesday session and the next Tuesday is where people relapse. IOP closes that gap. When the weeks get steadier, stepping down to outpatient is the natural next move, and the plan for it is written before IOP ends so the transition is not a restart.
How Long Does IOP Last?
Most clients are in IOP for several weeks to a few months, with hours reducing over that time. Some stay longer at a lower frequency because it is working and they want the accountability. Length is set by progress and by the clinical team’s weekly reviews, not by a fixed calendar, and insurance authorizations follow those reviews.
IOP Cost and Insurance Coverage
IOP is one of the most widely covered levels of addiction treatment, and we are in-network with the major Massachusetts commercial carriers. Your cost depends on your deductible, copay, and coinsurance, and admissions will verify the exact figure before you enroll. Because IOP uses fewer hours than PHP, it is also the least expensive structured program for people paying privately. Our guide to how much IOP costs has the detail.
After IOP
Finishing IOP is not the end of treatment; it is the point where treatment gets lighter. Clients move into outpatient therapy, an aftercare group, peer support meetings, or a combination, with a plan written before the last IOP session so there is no gap. Our aftercare program keeps you connected to the same team after the structured program ends.

Intensive Outpatient Treatment: Common Questions
Intensive outpatient program. “Intensive” because it is several sessions a week rather than one; “outpatient” because you live at home.
Yes, and most clients do. The evening track exists for that reason. If you need time off for sessions, IOP hours qualify for intermittent FMLA leave, and we complete the paperwork.
Both, along with co-occurring mental health conditions. We treat alcohol, opioids, benzodiazepines, stimulants, and cannabis in the same program.
Not necessarily. Some people start at IOP. Whether that is safe depends on withdrawal risk, how recent the last use was, and how stable things are at home, which the admissions assessment covers.
By nearly every commercial plan, as a standard level of substance use treatment. We verify your specific benefits before you start.
