PHP (Partial Hospitalization Program) is the more intensive level of care, typically running 5 to 6 days a week for 4 to 6 hours a day with daily clinical contact. IOP (Intensive Outpatient Program) is less intensive, usually 3 to 5 days a week for about 3 hours a session, and is built to fit around work, school, or family life. PHP tends to make sense as a step down from residential treatment or detox, or for anyone who needs daily structure. IOP tends to make sense for people who are more stable and ready to practice recovery skills while returning to daily responsibilities.
Choosing between PHP and IOP is one of the most common questions people ask once they’ve decided to get help for a substance use or mental health condition. Both are structured, evidence based levels of care. The real difference comes down to intensity, time commitment, and how much daily support a person needs while they rebuild their routine.
What Is PHP (Partial Hospitalization Program)?
Partial Hospitalization Program is a structured, full day treatment option for people who need more support than standard outpatient care but don’t require 24 hour supervision. Most PHP schedules run 5 to 6 days a week for 4 to 6 hours a day, and clients return home or to sober living each evening.
PHP typically includes:
- Daily group therapy and individual therapy
- Psychiatric evaluation and medication management
- Structured programming that mirrors the intensity of residential care
- A clear plan for stepping down to IOP as symptoms stabilize
PHP is often the right fit for someone stepping down from detox or residential treatment at Arkview’s Mechanicsburg location, or for someone whose symptoms are serious enough to need daily oversight but who doesn’t need to live on site.
What Is IOP (Intensive Outpatient Program)?
Intensive Outpatient Program is a step down from PHP, built for people who are more stable and ready to apply recovery skills in their everyday environment. IOP sessions usually run 3 to 5 days a week for about 3 hours a day, scheduled around work, school, or family obligations.
IOP typically includes:
- Group therapy several times a week
- Individual therapy as needed
- Relapse prevention planning and skill building
- Ongoing psychiatric support when medication is part of the treatment plan
Arkview also offers Virtual IOP for substance use disorder throughout Pennsylvania, delivered by Pennsylvania licensed clinicians, for people who want the structure of IOP without traveling to a facility every session.

How Arkview Determines Your Level of Care
During your Level of Care Assessment (LOCA), Arkview’s clinical team considers factors like:
- How much daily structure do you need right now? If your symptoms are severe or you’re just coming out of detox or residential care, PHP’s daily contact usually makes more sense.
- Can you safely manage mornings and evenings on your own? IOP assumes you can handle unstructured time between sessions. PHP assumes you need more support during the day.
- Do you need to keep working or attending school? IOP’s lighter schedule is built to fit around those obligations. PHP is a bigger time commitment.
- Is your primary concern mental health, substance use, or both? Arkview runs separate PHP and IOP tracks for mental health and for substance use, so the program you enter is built around your specific situation rather than a mixed caseload.
PHP and IOP for Mental Health vs. Substance Use at Arkview
Arkview Behavioral Health runs PHP and IOP as separate programs for substance use and for primary mental health conditions like depression, anxiety, bipolar disorder, and PTSD. That separation matters because someone in treatment for a primary mental health condition is treated in a program built around that population, not folded into a group focused on substance use recovery, and vice versa.
Both tracks are available at Arkview’s Mechanicsburg and York locations, with the same clinical team supporting clients whether they start in PHP, step down to IOP, or begin with Virtual IOP.

Frequently Asked Questions
Is PHP more intensive than IOP?
Yes. PHP runs 5 to 6 days a week for 4 to 6 hours a day with daily clinical contact, while IOP runs 3 to 5 days a week for about 3 hours a day. Most people step down from PHP to IOP as they stabilize. Ask admissions which level fits where you are right now.
Can I go straight into IOP without doing PHP first?
Yes, for many people IOP is the right starting point, especially if symptoms are manageable and daily responsibilities like work or school need to continue. Arkview’s admissions team reviews your situation to recommend a starting level. Start the conversation with admissions.
Does insurance cover PHP and IOP?
Most major insurers cover both levels of care when they’re clinically appropriate. Arkview accepts Blue Cross Blue Shield, Cigna, Geisinger, United Healthcare, UPMC Health Plan, and Tricare, and verifies your specific benefits before treatment starts. Contact admissions to confirm your plan.
Is there a virtual option for PHP or IOP?
Arkview offers Virtual IOP for substance use disorder statewide, delivered by Pennsylvania licensed clinicians. PHP is not currently offered virtually, since the daily, in-person structure is part of what makes it effective.
Does Arkview treat mental health and substance use in the same PHP or IOP groups?
No. Arkview runs separate PHP and IOP tracks for substance use and for primary mental health conditions, so treatment is built around the specific population rather than a mixed caseload. Learn more on the mental health programs page.
