If someone you love is struggling with substance use, the treatment world can feel like a wall of words. Inpatient, residential, PHP, IOP, outpatient. This guide explains what those terms mean in plain language, so you can figure out roughly where your family member fits and what to ask for next.
What "Levels of Care" Means and Why It Exists
"Levels of care" is the term clinicians use for how much support and structure a person needs at a given moment. More intensive care means more hours, more supervision, and more clinical attention. Less intensive care means more independence and fewer hours each week.
The point of having different levels is simple. Care is matched to need. A person in early, fragile recovery may need a lot of structure. A person who is more stable may do well with a few sessions a week. Most programs in the United States use a shared framework from the American Society of Addiction Medicine (ASAM) to describe these levels. We will use that framework here, kept plain.
Levels are not a ranking of how "serious" a person is, and they are not permanent. They describe a fit for right now.
A Plain Walk Down the Continuum
Here is the continuum from the most intensive level to the least. Each line notes who a level tends to fit. A clinical screen, not a guess, decides the actual placement.
- Inpatient or medical (ASAM Level 4). The most intensive level. A hospital setting with around-the-clock medical staff. This fits someone who needs medical monitoring, often for a serious or higher-risk withdrawal or another acute medical concern.
- Residential (ASAM Level 3.x). A live-in program, staffed day and night, without the full hospital medical setup. This fits someone who needs a stable, structured living environment to focus on recovery, away from triggers at home.
- Partial hospitalization, or PHP (ASAM Level 2.5). A day program. A person lives at home or in sober housing and attends treatment for many hours on most weekdays, then goes home at night. This fits someone who needs a high number of structured hours but does not need overnight supervision.
- Intensive outpatient, or IOP (ASAM Level 2.1). Several hours of structured treatment per week, spread across multiple days, while the person lives at home and keeps up with work, school, or family. This fits someone who needs real structure and group support but can stay safe outside of program hours.
- Outpatient (ASAM Level 1.0). The least intensive level. Regular individual or group sessions, often weekly. This fits someone who is more stable and needs ongoing support, or who is stepping down after a more intensive program.
Shift provides outpatient (1.0) and intensive outpatient (2.1) through telehealth. Shift does not provide residential or inpatient care. When a different level is the right fit, Shift can help refer up or down.

What Makes IOP "Intensive"
IOP sits in the middle of the continuum, and the word "intensive" points to the structure. Compared with standard weekly outpatient, IOP packs in more hours and more touchpoints.
A typical intensive outpatient program includes:
- More hours per week. Several sessions across multiple days, rather than one weekly visit.
- Group therapy. Regular groups where people work on skills and recovery together, guided by a clinician.
- Individual therapy. One-on-one sessions to work on personal goals and challenges.
- Medication-assisted treatment (MAT). When clinically appropriate, FDA-approved medications can be part of the plan, managed by the care team.
- Family programming. Sessions that bring family members into the process, since recovery affects the whole household.
The combination of more hours, group plus individual work, and medical support is what separates IOP from a standard weekly check-in.
What Virtual IOP Adds, and Where It Fits
Virtual IOP, sometimes called telehealth IOP, is intensive outpatient delivered over secure video instead of in a clinic. It sits at the same point on the continuum as in-person IOP (ASAM Level 2.1). The level of care is the same. The setting is different.
Delivering IOP virtually can remove some real barriers. There is no commute. People can join from home, which can make it easier to keep a job, stay in school, or manage caregiving. For families spread across a region, it can also make family sessions simpler to attend.
Shift is a fully telehealth program serving California, certified by the California Department of Health Care Services (DHCS). Records are protected under federal confidentiality rules for substance use treatment (42 CFR Part 2). Cohorts run in the morning, afternoon, and evening, so a person can pick a schedule that fits their life. You can read more about Shift's virtual IOP in California and what we do.
How People Move Between Levels
Moving between levels is normal and expected. It is part of how treatment is supposed to work.
"Stepping up" means moving to a more intensive level, for example from IOP to PHP or residential, when someone needs more support than their current level provides. "Stepping down" means moving to a less intensive level, for example from PHP to IOP, or from IOP to standard outpatient, as a person stabilizes.
A person might enter at one level, step down as they gain footing, and adjust again if life changes. None of that is failure. It is the care matching the need at each point. Shift can refer up to a higher level when that is the right call, and can be a step-down landing spot for someone leaving residential or PHP. See how it works for a walk through the day-to-day.
How to Figure Out the Right Starting Level
You do not have to diagnose the right level on your own. The honest answer is that a clinical screen decides placement, not a family member's best guess.
What you can do is gather what you know. How is the person's physical safety right now? Are they able to function at home, work, or school? Is there a history of higher-risk withdrawal? Is the home environment stable? These are the kinds of questions a clinical team will ask during an assessment, and they help match a person to the right level.
If you are not sure where to begin, a benefit check and a first conversation are a reasonable starting point. Shift can talk through the options and, when Shift is not the right fit, point you toward care that is. Families often find the for families resources a helpful place to start.
Frequently asked questions
What is the difference between IOP and PHP?
Both are structured outpatient programs where a person lives at home. PHP (ASAM Level 2.5) involves more hours, usually most of the day on most weekdays. IOP (ASAM Level 2.1) involves fewer hours spread across several days, which leaves room for work, school, or family. A clinical assessment determines which fits.
Is virtual IOP confidential?
Shift's records are protected under 42 CFR Part 2, the federal rule that governs the confidentiality of substance use disorder treatment records. Sessions are delivered over secure video. You can ask the care team how your information is handled before you enroll.
Does insurance cover virtual IOP at Shift?
Shift is out-of-network with commercial insurance carriers, which means Shift does not hold in-network contracts with them. Out-of-network benefits vary by plan. Shift offers a benefit check so you can understand what your specific plan may cover before deciding.
