Partial Hospitalization (PHP), Explained

What is partial hospitalization (PHP)?

Partial hospitalization is a defined level on the standardized continuum of addiction care — the most intensive form of outpatient treatment, sitting just below residential care and just above intensive outpatient 1Ref 1American Society of Addiction Medicine (2024).The ASAM Criteria.That ASAM defines a standardized continuum of care in which partial hospitalization is the most intensive outpatient level, between intensive outpatient and residential care, with placement based on assessed need rather than a fixed program length.. In practice it means attending treatment for most of the day, several or all weekdays, and then going home each night. The days are full: group therapy, individual counseling, medication management, and skills work, delivered with the kind of daily oversight that a weekly appointment cannot provide. Placement at this level is meant to follow an assessment of what a person actually needs, not a fixed program length 1Ref 1American Society of Addiction Medicine (2024).The ASAM Criteria.That ASAM defines a standardized continuum of care in which partial hospitalization is the most intensive outpatient level, between intensive outpatient and residential care, with placement based on assessed need rather than a fixed program length..

PHP (partial hospitalization program) is sometimes called day treatment; on the ASAM continuum it is Level 2.5.

PHP gives you full treatment days and your own bed at night — much of what residential offers, without moving in.

How PHP differs from IOP and residential care

PHP is defined mostly by hours and oversight. Compared with intensive outpatient — an IOP vs PHP question people ask constantly — PHP runs longer days and more of them, closer to a full-time treatment schedule, while IOP is several hours across fewer days. Compared with residential or inpatient care, PHP asks nothing of your nights: you sleep at home rather than in a facility. That single difference is the point of the level.

The right level is the one an assessment points to. Because no single treatment is right for everyone, matching the intensity to the person matters more than choosing the most hours available 2Ref 2National Institute on Drug Abuse (2018).Principles of Drug Addiction Treatment: A Research-Based Guide (Third Edition).That no single treatment is right for everyone and that remaining in treatment for an adequate time — generally at least three months, with longer often better — is critical to outcomes..

Who does PHP fit?

PHP fits people who need close, near-daily support but are medically safe to be at home overnight and have a stable enough home to return to each evening. It is a common landing place in two directions. Some people step up to PHP from a lighter outpatient level that was not holding recovery in place. Others step down to PHP from residential treatment or a hospital as they stabilize, keeping intensive daytime support while they re-enter ordinary life gradually. Either way, what carries the outcome is staying engaged in care long enough to benefit — generally at least three months of continued treatment across whatever levels a person moves through, with longer often better 2Ref 2National Institute on Drug Abuse (2018).Principles of Drug Addiction Treatment: A Research-Based Guide (Third Edition).That no single treatment is right for everyone and that remaining in treatment for an adequate time — generally at least three months, with longer often better — is critical to outcomes.. PHP is one intensive stretch within that longer arc, rarely the whole of it.

What a day in PHP looks like

A PHP daily schedule is built like a workday of treatment rather than a scattering of appointments. A typical day combines several therapy groups, individual counseling, psychoeducation, and medical or medication check-ins, often with a meal or breaks structured in. People usually arrive in the morning, spend most of the day in programming, and head home in the afternoon or evening. The exact mix varies by program and by what your assessment found, since matching the plan to the person matters more than any fixed template 2Ref 2National Institute on Drug Abuse (2018).Principles of Drug Addiction Treatment: A Research-Based Guide (Third Edition).That no single treatment is right for everyone and that remaining in treatment for an adequate time — generally at least three months, with longer often better — is critical to outcomes..

Because you return home each night, PHP also lets you carry the day's work straight into real life — trying out coping skills at home and bringing back what happened for the next day's groups. Good programs are built from approaches with evidence behind them and, importantly, are supported by the services that hold recovery together over time: counseling, care coordination, and connection to ongoing treatment 3Ref 3Substance Abuse and Mental Health Services Administration (2021).TIP 63: Medications for Opioid Use Disorder — Full Document.That the three FDA-approved medications for opioid use disorder are methadone, buprenorphine, and naltrexone, and that effective care pairs medication with the counseling and services that support recovery.. The full days are intense, but the structure is what many people in a fragile stretch of recovery genuinely need.

Medication is part of PHP

Medication belongs at this level. For opioid use disorder, the three FDA-approved medications are methadone, buprenorphine, and naltrexone, and effective care pairs medication with the counseling and services that support recovery 3Ref 3Substance Abuse and Mental Health Services Administration (2021).TIP 63: Medications for Opioid Use Disorder — Full Document.That the three FDA-approved medications for opioid use disorder are methadone, buprenorphine, and naltrexone, and that effective care pairs medication with the counseling and services that support recovery.. The guideline of record recommends treating opioid use disorder with methadone or buprenorphine rather than withdrawal management alone, says no medication should be withheld because someone is still using other substances, and warns against arbitrary time limits on it 4Ref 4American Society of Addiction Medicine (2020).The ASAM National Practice Guideline for the Treatment of Opioid Use Disorder — 2020 Focused Update.That the guideline recommends treating opioid use disorder with methadone or buprenorphine rather than withdrawal management alone, that no medication should be withheld because of ongoing use of other substances, and that medication should not be arbitrarily time-limited.. A PHP that prescribes or coordinates these medications is delivering standard, evidence-based care, not cutting a corner.

Being on medication for addiction is not trading one dependence for another. It is a standard of care that fits inside a day program as naturally as it fits anywhere else.

Cost, coverage, and parity

PHP costs more than IOP because it uses more hours and more staff time, though it is still less than round-the-clock residential care because there is no overnight stay. What you pay depends heavily on your plan and whether the program is in network, so checking your specific benefits is worth doing before committing. Coverage for day treatment is shaped by federal parity law: the Mental Health Parity and Addiction Equity Act generally requires that a plan covering mental-health and substance-use benefits not impose more restrictive limits on them than it does on medical and surgical care 5Ref 5Centers for Medicare & Medicaid Services (2024).Mental Health Parity and Addiction Equity Act (MHPAEA).That MHPAEA generally requires plans covering mental-health and substance-use benefits not to impose more restrictive limits than for medical and surgical benefits, but does not itself mandate that a plan cover substance-use treatment.. That is a real protection, but it has limits — parity does not by itself force a plan to cover substance-use treatment at all; it governs how a plan that does cover it may set the terms 5Ref 5Centers for Medicare & Medicaid Services (2024).Mental Health Parity and Addiction Equity Act (MHPAEA).That MHPAEA generally requires plans covering mental-health and substance-use benefits not to impose more restrictive limits than for medical and surgical benefits, but does not itself mandate that a plan cover substance-use treatment.. Reading your own plan document, or asking the insurer directly, is the only way to know what applies to a PHP stay.

Choosing a program and finding one

Because this level is expensive and demanding, it is worth choosing a program the way you would choose any serious treatment — not the one with the loudest marketing. Ask what the groups actually consist of, whether the program offers or coordinates medication, what its clinicians are licensed to do, and how it handles a step up or step down when your needs change. A good program answers those plainly; evasive answers are their own signal, and evidence-based treatment is the standard to hold a program to rather than amenities or promises.

For a neutral place to start that has no stake in admitting you, SAMHSA's National Helpline is free, confidential, and staffed around the clock at 1-800-662-HELP, and it provides referrals to local treatment and support rather than counseling on the call 6Ref 6Substance Abuse and Mental Health Services Administration (2024).SAMHSA's National Helpline.That 1-800-662-HELP is SAMHSA's free, confidential, around-the-clock treatment-referral and information service that provides referrals to local treatment and support rather than counseling.. A level-of-care assessment is the usual entry point, and it is the assessment — not a program's sales desk — that should decide whether PHP is the right fit.
