Partial Hospitalization Program
You want serious treatment without disappearing from your own life. A partial hospitalization program gives you most of inpatient's intensity by day, then sends you home to sleep in your own bed.
Battling addiction & ready for help?
What a Partial Hospitalization Program Is
A partial hospitalization program, almost always shortened to PHP, is the most intensive kind of addiction treatment you can get without checking in to live there. You spend most of the day at a treatment center — commonly five to six hours, around five days a week — doing structured therapy and medical care, and then you go home at night and sleep in your own bed. It is built to give you nearly the schedule and support of inpatient rehab while you keep one foot in your real life.
That last part is the whole point. PHP exists for people who need serious, daily structure to get steady but who have a safe, stable place to spend their evenings. You get the depth of treatment without having to disappear from your home, your kids, or your responsibilities. For a lot of people, that combination is exactly what makes starting feel possible instead of impossible.
If you are weighing this and the word “hospitalization” sounds heavier than you bargained for, the name oversells it. A PHP is not a hospital stay. It is a full day of treatment you commute to, and the way through is far more livable than the fear of it suggests.
- PHP is the most intensive level of care that still lets you sleep at home: it delivers close to an inpatient schedule by day, then you go home at night.
- Where you land on the ladder is matched to you, not picked off a menu: addiction medicine built placement criteria precisely so care fits each person, and people who get the matched level tend to complete treatment more often and stay abstinent longer[1].
- PHP works best as a bridge: it is a common step down right after detox or residential care, and a step up when lighter outpatient treatment is not holding.
- The handoff between levels is where recovery is most fragile: many people finish a higher level of care and never connect to the next one, which is exactly the gap PHP is built to close[2][3].
Where PHP Sits Among the Levels of Care
Addiction treatment is not one place you go. It is a range of options sorted by how intensive they are, from round-the-clock hospital-style care down to a single weekly appointment. Clinicians call this range the levels of care, and the published guidelines for it cover everything from ambulatory treatment to full inpatient management, scaled to how severe the situation is[4].
PHP sits high on that ladder — second only to inpatient. Picture a staircase. At the top is live-in residential care, where the facility takes over your day and your supervision completely. At the bottom is a standing therapy appointment you keep while you live your normal life. PHP is the top rung you can stand on and still go home each night. It asks for most of your day, most days of the week, which is why it delivers so much more than a few weekly hours can.
Two things decide which rung fits. The first is safety — whether stopping a substance could be medically dangerous, which decides whether you start at the very top with detox. The second is structure — how much daily scaffolding it takes to stay on track once your body is stable. PHP answers a specific version of that second question: you need a lot of structure, but not a locked-in place to get it. None of these rungs is a verdict on you. They are tools, and the smart move is the one that fits.
Inpatient, PHP, IOP, and Outpatient at a Glance
The clearest way to see where PHP lives is next to its neighbors. Read this top to bottom and find the row that sounds most like the situation you are trying to solve.
| Level of care | Hours | Where you sleep | Who it fits |
|---|---|---|---|
| Inpatient / residential | 24 hours a day, every day | At the facility | Severe addiction, an unsafe or unstable home, dangerous withdrawal, or repeated relapses at lower levels |
| Partial hospitalization (PHP) | Most of the day, ~5 days a week (commonly 5–6 hours) | At home | People who need near-daily structure but have a safe, stable place to spend nights |
| Intensive outpatient (IOP) | A few hours, a few days a week (often ~9–15 hours weekly) | At home | People stable enough to live at home who still need serious, regular support around work or family |
| Standard outpatient | Roughly an hour, about weekly | At home | Milder problems, or keeping recovery steady after a higher level |
The pattern down the column is intensity trading for freedom. Higher up means more structure and more clinical eyes on you. Lower down means more of your own life carrying the weight. PHP is the sweet spot for people who need a great deal of support but are ready to practice recovery in the same world they will keep living in.
What a PHP Day Actually Includes
A PHP is not just supervised time — it is a packed, structured treatment day. The hours are filled with the same core ingredients as the most serious levels of care, delivered in a daily rhythm.
Group therapy is the backbone. Most of the day runs on group sessions, where you do the real work of recovery alongside other people facing the same fight — building skills, processing what using cost you, and learning that you are not uniquely broken. Individual therapy is woven in so you have private, one-on-one time to go after the personal roots of your addiction with a clinician who knows your story.
Psychiatric and medical oversight runs underneath all of it. Because PHP is a medical level of care, clinicians are watching your physical and mental health throughout — adjusting as you stabilize and catching problems early. Medication is part of the toolkit where it helps. For opioid and alcohol use disorders especially, medication is a cornerstone of effective treatment, and a program that supports it is handing you a fuller set of tools[5]. It is worth asking any program directly whether they offer medication, because not every facility makes it available.
Skills and relapse prevention are the practical core. A good chunk of the day goes to learning concrete tools: how to handle a craving without acting on it, how to spot the situations and feelings that have set off using before, and what to actually do when one shows up. This is the part you take home — and because you go home every night, you get to test those skills against real life immediately and bring back what happened.
How PHP Compares to IOP and Inpatient
Two comparisons clear up most of the confusion about where PHP fits.
PHP versus IOP comes down to hours. Both let you live at home while you get real treatment — that part is identical. The difference is the dose. Intensive outpatient runs a few hours a few days a week, often around nine to fifteen hours total. PHP fills most of the day most days, closer to thirty hours a week. A natural path is to start in PHP and step down to IOP as you steady, keeping the support while you take back more of your time.
PHP versus inpatient comes down to nights. The treatment days look similar — both are intensive and full — but inpatient keeps you at the facility around the clock, while PHP sends you home each evening. Inpatient is built for the hardest end of the spectrum: dangerous withdrawal, a home environment tangled up with using, or a history of relapsing the moment outside support drops away. PHP is for people who need that level of daytime intensity but have somewhere safe and stable to land at night.
Who PHP Is Right For
PHP fits two kinds of moments especially well, and they pull in opposite directions on the ladder.
It is a strong step down. Right after medical detox or a residential stay, dropping straight to a weekly appointment is a long fall. PHP catches you there. Detox clears the drug and stabilizes your body, but it does not treat the addiction underneath, and the stretch right after is where people are most likely to slip — many finish that first level and never connect to ongoing care[2][6]. Continuing on a medication for the underlying disorder while you step down is linked to staying connected to care rather than falling through the gap[3]. PHP is built to be where that catch happens.
It is also a strong step up. If you have been in standard outpatient or IOP and it is not holding — cravings are winning, you have slipped, life is unraveling faster than weekly sessions can address — moving up to PHP is not a failure. It is reading the situation clearly and getting the support that fits. Stepping up a level when a lighter one stops working is the system doing exactly what it was designed to do.
Underneath both moments is a clinical match, and you do not have to make it alone. Placement is meant to be driven by your own needs and goals rather than a fixed formula[7], and getting that match right genuinely matters — receiving the level of care the criteria point to is consistently tied to better treatment and health outcomes[8]. A clinician sizing up withdrawal risk, your home environment, any co-occurring mental-health condition, and how much structure you need is exactly how the right rung gets chosen.
When the pandemic forced treatment online, intensive outpatient care for substance use proved feasible to deliver and study at scale, which widened access for people far from a clinic or juggling work and caregiving[9]. Some programs now run partial hospitalization and intensive outpatient in virtual or hybrid formats, so the daily structure can reach people who could never have driven to a center five days a week.
How Long PHP Lasts and What Comes Next
Most people are in PHP for a matter of weeks, not months — typically a few weeks of full days, adjusted to how you are doing rather than a fixed sentence. The aim is not to stay as high on the ladder as possible. It is to use the intensity to get steady, then step down to a level that takes less of your time as you carry more of the weight yourself.
A common path runs detox, then residential or PHP, then IOP, then standard outpatient, often with sober living alongside the later steps — each move a step down as you grow stronger. Recovery is rarely a straight line, and the ladder is built to flex with you. If a lower rung stops holding, stepping back up for a while is wisdom, not relapse of character. Recovery support that wraps around formal treatment, including abstinence-based recovery housing, is the most widely available form of recovery support in the country, and it is recognized as part of the continuum, not an extra[10].
PHP is serious treatment that lets you keep one foot in your real life — the structure of a program with the ground of your own home underneath you. It pairs well with continued medication for addiction and the talk therapy that carries recovery forward once the intensity steps down.

Frequently asked questions
What is a partial hospitalization program (PHP)?
A partial hospitalization program is the most intensive level of addiction treatment that still lets you sleep at home. You spend most of the day at a treatment center — commonly five to six hours, around five days a week — in structured group and individual therapy with psychiatric and medical oversight, then you go home at night. Despite the name, it is not an overnight hospital stay. It delivers close to the schedule of inpatient rehab for people who need that much daily support but have a safe, stable place to spend their evenings. Where a person lands on the ladder of care is meant to be matched to their needs, and people who get the matched level tend to complete treatment more often and stay abstinent longer[1].
How many hours a day is PHP, and how long does it last?
A PHP day usually runs about five to six hours, roughly five days a week, so it fills most of the day most days — close to thirty hours of treatment in a typical week. Most people stay in PHP for a matter of weeks rather than months, adjusted to how they are doing rather than a fixed length. The point is to use that intensity to get steady, then step down to a lighter level such as intensive outpatient as you take back more of your own time. Recovery is rarely a straight line, and the level of care is meant to be revisited as your needs change[7].
What is the difference between PHP and IOP?
The difference is hours, not approach. Both partial hospitalization (PHP) and intensive outpatient (IOP) let you live at home while you get real, structured treatment built on group therapy, individual therapy, and relapse-prevention skills. PHP is the more intensive of the two — most of the day, most days of the week. IOP dials the time down to a few hours a few days a week, often around nine to fifteen hours total, so it fits around a job, school, or family. A common path is to start in PHP and step down to IOP as you steady, keeping the support while reclaiming more of your time. Both formats also adapt well to telehealth, which has widened access for people far from a clinic[9].
What is the difference between PHP and inpatient rehab?
The difference comes down to nights. The treatment days look similar — both are intensive and full — but inpatient (residential) rehab keeps you at the facility around the clock, while PHP sends you home each evening. Inpatient is built for the hardest end of the spectrum: dangerous withdrawal, a home environment tangled up with using, or a history of relapsing as soon as outside support drops away. PHP is for people who need that level of daytime intensity but have somewhere safe and stable to land at night. Many people actually move from one to the other, using PHP as the step down right after a residential stay so they do not fall straight from round-the-clock care to a weekly appointment.
Who is PHP the right fit for?
PHP fits two moments especially well. It is a strong step down right after medical detox or residential care, when dropping straight to weekly therapy would be too big a fall — detox stabilizes the body but does not treat the addiction underneath, and many people finish a higher level and never connect to ongoing care, which is exactly the gap PHP closes[2][3]. It is also a strong step up when standard outpatient or IOP is not holding and someone needs more structure to get steady. The common thread is needing serious daily support while having a safe, sober place to spend nights. Getting that match right matters — receiving the level of care the criteria point to is tied to better treatment outcomes[8] — and a clinician can help you sort it out.
Does insurance cover partial hospitalization?
PHP is a recognized medical level of care, and many health plans — including Medicaid in many states — cover it when it is medically necessary, though specifics vary widely by plan, state, and program. Insurers typically decide coverage based on placement criteria that weigh how much structure and supervision a person actually needs, which is the same kind of needs-based matching clinicians use to choose a level of care in the first place[1]. The practical move is to ask the treatment program directly: good admissions teams verify your benefits, explain what your plan covers, and lay out any out-of-pocket cost before you start, so you are not guessing. Cost should not be the thing that keeps you from getting help — there are people whose job is to help you work it out.
