If you have been asked to choose between a Partial Hospitalization Program and an Intensive Outpatient Program, or if a clinician has recommended one and you are not sure why, this article is for you. PHP and IOP are the two outpatient levels of care that sit on the recovery arc between inpatient treatment and standard weekly therapy. They share the same clinical model. They differ in how many hours per week a person spends inside structured treatment, and that difference matters more than most patients and families initially realize.
Both programs are delivered at Roanoke Refuge by the same clinical team, in the same building, with the same evidence-based approaches. The choice between them is a clinical decision made during the intake assessment, not a menu the patient picks from. The framework that guides it is the American Society of Addiction Medicine criteria, the same set of placement criteria used by hospitals, insurers, and outpatient programs across the country.
What PHP Looks Like Day to Day
Partial Hospitalization is full-day outpatient treatment. A typical PHP day at Roanoke Refuge runs approximately five hours and includes morning check-in, two to three clinical groups, individual therapy on a recurring schedule, a structured lunch break, and an afternoon wrap-up. Patients attend five days per week. The day has the rhythm of a workday, just with the work being recovery instead of email.
PHP is typically the right level of care for a patient who is stepping down from inpatient or detox and is not yet ready for a part-day schedule, or for a patient stepping up from weekly outpatient therapy that is no longer holding the work. The hours-per-week dose is high because the patient needs that much structure to stabilize. Once the clinical work has progressed and the patient demonstrates the skills and stability to hold a less-intensive schedule, the team steps them down to IOP.
What IOP Looks Like Day to Day
Intensive Outpatient is part-day outpatient treatment. IOP at Roanoke Refuge runs nine or more hours per week across three or more days, with each session typically lasting three hours in the morning or evening. The shorter hours mean the patient can hold work, school, or family responsibilities alongside the clinical work. The clinical content is largely the same as PHP — process group therapy, psychoeducation, individual therapy, case management — just delivered in a more concentrated format.
IOP is the right level for a patient who has the stability to engage in the broader life around treatment but still needs structured clinical hours each week. It is also the level most patients step into after PHP, and it is the level most patients spend the longest at across their treatment episode. The recovery work that builds the most durable change tends to happen here, in the months when the patient is testing what they learned in higher-intensity care against the real conditions of their daily life.
How Clinicians Choose Between Them
The placement decision is made during the clinical intake assessment, a 60- to 90-minute conversation with a licensed clinician that walks through six dimensions of the patient’s situation. These include the medical picture, including any withdrawal risk; the emotional and behavioral picture, including co-occurring mental health conditions; the patient’s readiness and engagement; the recovery environment, including who they live with and what their day looks like; the relapse and continued-use history; and the acute intoxication picture if present. The dimensions are the ASAM criteria, and they are what determine which level of care fits the patient sitting in the room.
A patient with high withdrawal risk, recent multiple recurrences, an unstable home environment, or significant co-occurring symptoms typically lands in PHP. A patient with a more stable home life, employment that needs to continue, no significant withdrawal risk, and clinical symptoms that respond well to part-day structure typically lands in IOP. Most patients move through both levels across the course of an episode — PHP first to stabilize, then IOP to continue building skills in the broader life around them.
The Practical Differences in One Place
PHP runs about 25 hours per week across five days. IOP runs about 9 to 12 hours per week across three or more days. PHP is the right starting point for higher-acuity patients or step-downs from inpatient or detox. IOP is the right starting point for patients with a stable enough recovery environment to hold the broader work. The two programs share the same therapeutic approaches, the same clinical team, and the same evidence base. The structural difference is hours per week.
Insurance covers both PHP and IOP at most commercial plans and Virginia Medicaid, and the level is verified during the free benefit-verification call that precedes any clinical commitment.
Which Level Is Right for You
The honest answer is that the level is not picked from a website. The level is determined by the clinical assessment. What this article can do is set expectations, name the framework, and explain what each level looks like day to day so that you arrive at the assessment with a working vocabulary. The assessment itself is a conversation. The clinician will walk through your situation, your goals, and the practical constraints around your life, and the level-of-care recommendation will follow from that conversation.
If you are weighing this decision tonight from a kitchen table in Cave Spring, a quiet bedroom in Daleville, or a parked car somewhere in the Roanoke Valley, the next step is the conversation with admissions. The call is confidential. Insurance verification happens before any clinical commitment is made. And the level-of-care recommendation will be based on your situation, not on what fills which program. That is the standard the team holds itself to, and it is the standard you should expect from any outpatient program you talk with.
