A partial hospitalization program (PHP) for opioid use disorder works as day treatment. You spend the day at the program. At night, you sleep at home or in a sober living place. PHP does not have a standard length. The care team looks at your progress and needs to set your stay.[1] For details on that evening routine, our guide to sober living after opioid rehab covers what to expect and how to choose a home.

PHP serves as one piece of care. It does not replace medication treatment if you need it. Whether PHP fits you depends on your needs and the program's services. Check our guide on the levels of opioid rehab to find more options.

Understanding PHP for Opioid Use Disorder

PHP is a kind of intensive outpatient care. Treatment happens during the day. You normally go home at night.

PHP is a setting, not a specific treatment for opioid use disorder. Services differ across programs. Access to medicine can change by provider. Ask what treatments a program offers.

Understanding the gap between dependence and a disorder is useful. Long-term use of many drugs can cause physical dependence. This can happen even with proper use. Being dependent is not the same as being addicted.[2] A doctor or licensed clinician must diagnose opioid use disorder.

These stats point to how widespread the issue is. They do not show if PHP fits your case. A clinician reviews your needs to find the right care level.

Opioid Use Disorder PHP: Medication Details

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]

Programs handle medication in different ways. Some PHPs give it through internal staff. Other sites use an outside prescriber or an opioid treatment program. Counseling and extra supports help. But if medication is the right choice for you, these supports do not replace it.

When speaking with a program, ask who manages your medications. Inquire about how appointments are scheduled. Make sure you understand how your treatment plan continues after your stay. This ensures a clear path forward and prevents gaps in your care.

Comparing PHP, IOP, Residential Care, and Detox

The ASAM framework lists five main levels of care. It includes sublevels based on medical supervision.[9] Each level plays a distinct role in recovery. Your specific needs decide which one is right for you.

Level of CareTypical SettingBroad PurposeKey Questions to Ask
Standard OutpatientClinic or officeOngoing therapy while living at homeDoes it offer medication for opioid use disorder? What is the follow-up plan?
Intensive Outpatient (IOP)Clinic or group settingGroup and individual sessions several times a weekHow does the schedule fit work or school? Is medication treatment included?
Partial Hospitalization (PHP)Day treatment facilityIntensive daytime care, returning home each nightWhat are the daily hours? How is medication managed during the day?
Withdrawal Management (Detox)Medical facility or clinicManaging physical withdrawal safely under medical supervisionIs this followed by ongoing treatment with medications for opioid use disorder? Who plans the next step?

Names and schedules for these programs differ by place. Always check details with the provider.

Why Detox Falls Short

Withdrawal management helps you get through physical withdrawal safely. However, detox by itself is not enough for substance use disorder.[10] Without continued care, people often use drugs again. CDC guidance warns against doing detox without meds for opioid use disorder. This increases risks for resuming drug use, overdose, and overdose death.[11]

Detox is a starting point, not a final goal. It should fit into a broader plan with ongoing therapy and medication support. Look for providers who link withdrawal to long-term care when you compare options. Read about opioid detox duration to understand that phase. Our list of medical detox programs helps you find local options focused on safety and next steps for medical help during withdrawal. For a closer look at that timeline, our guide to opioid detox duration explains what to expect during that phase.

Typical Days and Timelines in a PHP for Opioid Use Disorder

What a day looks like in a partial hospitalization program (PHP) can differ by facility. Structure and flexibility are mixed in most programs. Individual and group counseling are common services.

Steps, A typical day in PHP. 1. Morning group session; 2. Midday one-on-one meeting; 3. Afternoon group session; 4. Return home.

Here is a sample daily layout to help you picture the flow. Specific times and tasks shift from one program to the next.

  • Morning: You arrive for a group session focused on coping skills or psychoeducation.
  • Midday: A therapist works with you one-on-one on your personal goals. You might also talk to a prescriber about your medication.
  • Afternoon: You join a second group session that may focus on peer support or family therapy.
  • Evening: You go back home. Some programs ask for homework or want you to use the skills you practiced that day.

Every program puts together its own schedule. So, these items are common, but they are not a guarantee.

Care teams often link your PHP treatment with your other doctors. They combine substance use disorder care with your other health services.[12] This keeps your full treatment plan connected.

What Drives the Length of Stay

A PHP stay does not come with a fixed number of weeks. The American Society of Addiction Medicine (ASAM) says the length of treatment should fit your progress.[1] It should not follow a set calendar. Your needs help shape the timeline. The program's structure is also a factor. How you answer to care matters too. Teams look at your progress on a regular basis. They change the plan as you go along.

A Sample Step-by-Step Path

This path shows where PHP fits in addiction treatment. It is a sample, not a hard rule. Not everyone goes to detox before starting PHP. Dropping to a lower level of care does not stop medication treatment.

  1. 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.

  2. 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]

  3. Ongoing Care

    You keep getting support through follow-ups.[12] Community resources help too.

In general, intensive outpatient treatment offers 6 to 19 hours a week. These hours cover services like individual and group counseling, medication management, family therapy, educational groups, occupational and recreational therapy, and other therapies.[13] That range is for IOP, not PHP. Check the daily schedule with the program. Also ask how they decide when you are ready to move on.

When PHP Fits, and When to Consider Other Care

A medical decision picks the right care. A qualified provider checks your safety and needs. One symptom or a quiz is not enough for them.

Six areas are covered by the ASAM Criteria. This includes health issues and withdrawal risks.[9] It matches your needs to care intensity.[14] Whole-person care is the goal. It handles legal, social, mental, and medical needs.[15]

PHP is an intensive, outpatient service.[16] It may fit if you need daytime structure but can be safe at home overnight. For example, it might suit someone who needs regular counseling and medication management but is safe at night. Detox is not always the first step; your current needs set the start point.

Conversely, you may need to evaluate a higher level of care if you have ongoing withdrawal symptoms that require constant medical monitoring, serious medical complications, or safety concerns that cannot be managed in a home setting. Your providers will ask about these points to find the right fit:

  • Withdrawal: Is medical monitoring a need for you?
  • Mental health: Do you carry any other conditions?
  • History: Have you used other levels of care?
  • Home: Is your living situation steady?
  • Logistics: Can you make it to sessions on time?

Check out our level of care assessment guide if you are not certain.

Prep for your visit with the check below. It does not pick your care level.

Questions to Discuss With a Provider

  1. Has a provider checked your withdrawal and health needs?
  2. Does the program offer or manage medication for opioid use disorder?
  3. Is the schedule and transport plan workable for you?
  4. Do you know what support exists outside program hours?
  5. Is there a clear plan after PHP ends?

This self-check is for information only and isn't a diagnosis. It does not determine your level of care.

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.
