PHP vs. IOP: What Is the Difference?

The main difference between a partial hospitalization program (PHP) and an intensive outpatient program (IOP) is how much structured treatment time each one involves. PHP provides more hours of treatment on treatment days, while IOP provides fewer, which leaves more room for work, school and family. Both are outpatient levels of care for adults, and both can support people with substance use, mental health conditions or both.

The right choice depends on your symptoms, your safety and how much structure your daily life allows, and an assessment can help sort that out.
