A partial hospitalization program, PHP, offers a highly structured environment for people battling drug addiction and mental health issues. Intensive outpatient programs provide more flexible schedules for individuals who can adhere to treatment with less supervision. Find out more about these programs and Capital Recovery’s comprehensive approach.
Key Takeaways
- When battling substance use disorders and mental health issues, it’s essential to be matched with the appropriate level of care.
- PHPs and IOPs are both types of outpatient care, offering evidence-based therapies, but PHP provides more intense treatment for individuals with relapse or crisis risk. IOP offers fewer hours and suits people who can adhere to treatment without highly structured support.
- A thorough evaluation determines the appropriate level of care. Reassessments take place throughout treatment, and clients can move between levels based on progress.

Introduction
Fighting substance use disorders isn’t easy. Matching clients with the right level of care is essential to a personalized approach.
Partial hospitalization programs, PHPs, and intensive outpatient programs, IOPs, are two levels of outpatient treatment offering care at different intensities. PHPs are more structured, while IOPs are more flexible, meeting clients where they are on the treatment spectrum. Learn more about what these programs offer.
What is a Partial Hospitalization Program?
A partial hospitalization program offers structured support for individuals who are dealing with severe symptoms of substance abuse and mental health issues. The program offers therapy sessions several hours a day, several days a week, providing a full-time approach to care. Capital Recovery’s PHP takes place Monday to Friday; clients can return home at night.
PHP is recommended for people in the following situations:
- High relapse or crisis risk
- A stable home environment
- Battling serious mental health conditions that contribute to substance use disorders, which is common, as per SAMHSA research showing co-occurring disorders impacted 48.4 million people 12 and over in 2024
- Individuals stepping down from residential treatment
What is an Intensive Outpatient Program?
An intensive outpatient program is more flexible and requires fewer clinical hours. Clients typically attend 3 hours a day, 3-5 days a week, depending on treatment needs. Care can typically be scheduled around work, school, and other responsibilities.
IOP could be recommended for individuals who:
- Can adhere to treatment with less supervision
- Are stepping down from a partial care program
- Need to step up from traditional outpatient therapy
- Have a stable home environment
How Are PHP and IOP Similar?
While PHP and IOP differ in intensity and structure, they offer similar treatment modalities. For example, both provide:
- Evidence-Based Therapies: Services like cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and motivational interviewing (MI) teach clients coping skills to guide emotional regulation and treatment adherence.
- Individual Therapy: One-on-one settings allow providers to guide a personalized treatment plan and gain deeper insight into the client’s needs.
- Group Therapy Sessions: Reduce feelings of isolation and help clients learn from each other.
- Family Therapy: Family members are often brought into therapy sessions so they can learn about their loved one’s condition and help create a healing environment.
- Medication Management: When necessary, as part of detox and mental health treatment programs.
- Psychoeducation: Clients learn more about their condition and how to handle it.
Additionally, both programs may be structured similarly, with a check-in at the beginning, a review of feelings at the end, and sessions provided throughout the day. They are both part of a comprehensive care plan, with each level serving as a primary form of care or a step up or down from a previous level.
What Are the Key Differences Between PHP and IOP?

The key differences between PHP and IOP include care intensity, time commitment, medical supervision and staffing ratios, and cost and insurance considerations.
- Intensity of Care: PHP is recommended for clients who need a structured environment and stabilization. IOP is less intense.
- Time Commitment: PHP’s full-time approach requires a greater time commitment than a more flexible IOP.
- Medical Supervision and Staffing Ratios: PHP’s intensity typically means more clinical support, with a focus on medication management.
- Cost and Insurance: PHP is more intensive, requires more hours, and is therefore more expensive than a standard IOP. In terms of insurance, that means higher reimbursement amounts and stricter authorization requirements.
How Do I Know Which Therapeutic Services Are Right For Me?
Clinicians typically assess the appropriate level of care after a thorough evaluation. Medical professionals will conduct an evaluation to learn about your physical and mental health and substance use history. They will compare outcomes against American Society of Addiction Medicine (ASAM) criteria, a professional medical society that publishes clinical guidelines for addiction treatment.
Research on treatment settings consistently shows that matching individuals to the appropriate level of care using structured criteria such as the ASAM Criteria is critical to outcomes: a well-matched, stable, motivated client may do well in a lower-intensity setting, while someone with a more severe or repeated relapse history often needs a more intensive level to achieve initial stability.
Reassessments occur regularly, and the team adjusts treatment intensity based on client progress; clients may move up or down across treatment levels.

FAQs
What happens after completing PHP or IOP?
After completing IOP, clients can move on to traditional outpatient treatment with weekly therapy sessions, followed by our aftercare program. We offer continued support to guide long-term recovery, providing resources, ongoing therapy, and check-ins.
Can I switch from PHP to IOP (or vice versa) if my needs change?
Yes, clinics conduct regular assessments and evaluations to ensure you are matched with the appropriate level of care throughout treatment.
Will my insurance cover PHP and IOP the same way?
Most major insurance companies cover both PHP and IOP. However, PHP typically requires more rigorous prior authorization and ongoing utilization review due to its higher intensity and cost. Coverage also varies by plan, so ask your provider and treatment center what you might be paying for.
Can I work or go to school while in IOP?
Yes, because IOP typically requires less time, you can usually schedule treatment around school, work, and other responsibilities.
How do I know if I need PHP or IOP to start?
You will undergo a thorough clinical evaluation. We will compare your symptoms against ASAM criteria to match you with the appropriate level of care.
