Day treatment is what a partial hospitalization program (PHP) for opioid use disorder is. You attend the program while awake and sleep at home or in a sober living place. There is no set time frame for PHP. Your care team looks at your progress and needs to set your stay length.[1]
PHP is just one piece of your care plan. It does not take the place of medication treatment when you need that. Your own needs and what the program offers shape if PHP works for you. Learn about other choices in our guide on the levels of opioid rehab. If your schedule makes daily care difficult, our guide to weekend rehab for opioids shows how to fit treatment around work.

What PHP for Opioid Use Disorder Involves
Partial hospitalization (PHP) is a form of intensive outpatient care. You attend treatment sessions during the day. At night, you typically return home.
PHP is a setting for care. It is not one specific treatment for opioid use disorder. Programs give different services. Getting medicine can change by provider. Ask what care a program gives.
It helps to tell the gap between dependence and a disorder. Long-term use of many drugs can cause physical dependence. This can happen even with proper use. Dependence by itself is not addiction.[2] A doctor or licensed clinician is the only one who can diagnose opioid use disorder.
5.7 million
estimated U.S. people age 12 or older had opioid use disorder in 2023[3]
2 of 11
DSM-5-TR criteria needed within 12 months for a diagnosis[4]
These figures show how widespread the issue is. They do not indicate if PHP suits you. A clinician checks your needs to select the right care level.
Using Medication for Opioid Use Disorder in PHP
Medication is a key part of treatment for opioid use disorder. The FDA has approved methadone, buprenorphine, and naltrexone for this purpose.[6] NIDA says these medications are effective and evidence-based.[7] Studies show that people on methadone or buprenorphine have lower rates of death from all causes and overdose.[8]
Each facility handles medication differently. Some PHPs give it via their own staff. Others partner with an outside prescriber or an opioid treatment program. Counseling and other supports help. Yet they cannot take the place of medication if it is the right fit for you.
Ask the program who manages your medications. Find out how appointments are set. Also, clarify how your treatment plan continues after your stay ends. This keeps your path forward clear and prevents gaps in your care.
How PHP, IOP, Residential Care, and Detox Compare
The ASAM framework has five main levels of care. It also adds sublevels based on medical supervision.[9] Each level does a different job in recovery. Your needs decide which one is right.
| Level of Care | Typical Setting | Broad Purpose | Key Questions to Ask |
|---|---|---|---|
| Standard Outpatient | Clinic or office | Ongoing therapy while living at home | Does it offer medication for opioid use disorder? What is the follow-up plan? |
| Intensive Outpatient (IOP) | Clinic or group setting | Group and individual sessions several times a week | How does the schedule fit work or school? Is medication treatment included? |
| Partial Hospitalization (PHP) | Day treatment facility | Intensive daytime care, returning home each night | What are the daily hours? How is medication managed during the day? |
| Withdrawal Management (Detox) | Medical facility or clinic | Managing physical withdrawal safely under medical supervision | Is this followed by ongoing treatment with medications for opioid use disorder? Who plans the next step? |
Schedules and program names differ by area. Check the details with the provider.
Why Detox Alone Does Not Work
Withdrawal management helps you pass physical withdrawal safely. Yet detox by itself does not treat substance use disorder.[10] Without ongoing care, people often relapse. CDC guidance advises against detox without meds for opioid use disorder. This increases risks for resuming drug use, overdose, and overdose death.[11]
Think of detox as the first step, not the finish line. It belongs in a larger plan that adds therapy and medication support. When you weigh options, seek providers who connect withdrawal to long-term care. Learn about that next phase in our guide to opioid detox duration. Our list of medical detox programs helps you find local spots that focus on safety and next steps for medical help during withdrawal.
Sample PHP Days and Treatment Timelines
Days in a partial hospitalization program (PHP) look different at each facility. Most plans blend structure with some flexibility. Group and individual counseling are common parts of the day.
To show what a day may look like, here is one sample schedule. Keep in mind that times and activities shift from program to program.
- A group session on coping skills or psychoeducation is where you arrive.Morning:
- Midday: A therapist meets with you one-on-one to talk about your personal goals. You may also see a prescriber to manage your medication.
- Afternoon: You participate in another group session, which might involve family therapy or peer support.
- Evening: You head home. Some programs give homework or push you to practice the skills you learned that day.
These things are typical, yet not promised. Each program makes its own plan.
Care teams often link your PHP treatment with your other doctors. They weave substance use disorder care into your other health services.[12] This keeps your overall treatment connected.
What Makes Length Change
A PHP stay does not have one set week count. The American Society of Addiction Medicine (ASAM) notes that treatment length should fit your progress.[1] It should not track a fixed calendar. Your needs help set the timeline. Program structure is another factor. How you react to care counts as well. Teams check your progress on a regular basis. They tweak the plan as you move forward.
A Sample Order of Steps
This path shows where PHP sits in addiction treatment. It serves as a sample, not a rigid set of rules. Not everyone goes to detox before PHP. Stepping down to less intensive care does not stop medication treatment.
Check and Plan
You finish an evaluation to see what you need. Your team makes a personal plan. It may include medication for opioid use disorder and therapy goals.
Next Steps
The team looks at your progress. They decide if you should stay in PHP. Or you may step down to intensive outpatient care (IOP). Another level of care is also possible.[1]
Ongoing Care
You keep getting support through follow-ups.[12] Community resources help too.
Intensive outpatient treatment generally provides 6 to 19 hours per week of services such as individual and group counseling, medication management, family therapy, educational groups, occupational and recreational therapy, and other therapies.[13] This range describes IOP, not PHP. Always ask the program about its daily schedule. Ask how they decide when it is time to move on.
Is PHP Right for You? When to Look Elsewhere
Picking the right care is a medical decision. A qualified provider looks at your needs and safety. They do not base this on a single symptom or a quiz.
The ASAM Criteria looks at six areas. This covers health issues and withdrawal risks.[9] It matches care intensity to your needs.[14] Good care treats the whole person. It handles medical, mental, social, and legal needs.[15]
PHP is an intensive, outpatient service.[16] It may work well if you want daytime structure but can sleep safely at home. For instance, it might fit someone needing regular counseling and medication management who is safe overnight. Not everyone starts with detox; your current needs set the starting point.
On the other hand, you may need a higher level of care. This is true if you have steady withdrawal signs that need constant medical watching. It is also true if you have big health problems. Or if you have safety risks that are hard to handle at home. Providers will ask about these things to help pick the right fit:
- Withdrawal: Is medical monitoring needed?
- Mental health: Do you have other health conditions?
- History: Have you used other care levels?
- Home: Is your home life stable?
- Logistics: Can you arrive for sessions on time?

Frequently Asked Questions
What qualifies as opioid use disorder?
Doctors look at a pattern of symptoms. They check how these signs affect your life. It is not just about taking an opioid. DSM-5-TR classifies the condition as mild with 2–3 criteria, moderate with 4–5, and severe with 6 or more.[20] A qualified clinician makes this diagnosis.
Is PHP a form of rehab?
Yes. "Rehab" is a broad term for treatment programs that help people recover from substance use disorders. Partial Hospitalization (PHP) is one specific, structured, non-residential option within that spectrum. It offers intensive daytime care while allowing you to return home in the evenings, fitting between residential treatment and less intensive outpatient care.[16]
How long does PHP for opioid use disorder usually last?
There is no single PHP length that fits everyone. NIDA reports that research indicates most people who need treatment for drug addiction need at least three months in treatment to significantly reduce or stop drug use, but this is a general finding, not a PHP-specific stay length.[15] Ask the team how often they check your progress.
Can PHP provide or coordinate medication treatment for opioid use disorder?
Some programs provide medication treatment. Others work with an outside doctor or clinic. Methadone treatment for opioid use disorder is generally provided through a federally certified opioid treatment program, subject to specific regulatory exceptions.[21] Ask who prescribes your meds and how care continues after PHP ends.
What are the hardest addictions to quit?
There is no reliable ranking for who finds it hardest to stop. No single treatment is appropriate for everyone, and effective care should be tailored to individual needs.[22] A personal health check is more useful than comparing substances.
Does physical dependence mean someone has opioid use disorder?
Not necessarily. Physical dependence can happen with prescribed opioids. It is not a diagnosis by itself. DSM-5-TR does not count tolerance or withdrawal toward the diagnosis when those symptoms occur solely during appropriate medical treatment.[23] A clinician can help tell the difference between these two things.
