Levels of Care Mental Health: IOP vs PHP vs Inpatient

Mental health care runs on four levels, set by weekly hours and where you sleep. This guide helps Texas adults and parents choose between therapy, an IOP, a day program or a hospital stay.

The four levels of care in mental health are outpatient (under 9 hours a week), intensive outpatient or IOP (9 to 19), partial hospitalization or PHP (20 or more, home each night) and inpatient (24-hour hospital care), and you need the lowest one that keeps you safe. Mindful Health’s intensive outpatient program in Texas page covers IOP schedules. SAMHSA counted 54.6 million U.S. adults with a mental illness in 2025.

How do the levels of care in mental health compare?

The four levels differ in weekly hours, where you sleep and how much of normal life you keep. Clinicians and insurers name them with two scales: LOCUS for mental health and the ASAM Criteria for substance use.

Outpatient care takes under 9 hours a week, often about 1, and you keep a full work or school schedule. The ASAM Criteria Fourth Edition (2023) call it Level 1.5, and LOCUS places it at Level I or II. At Mindful Health it covers therapy, psychiatry, TMS and Spravato.

An IOP takes 9 to 19 hours a week, and you sleep at home. Most people keep working around 3-hour blocks. It is ASAM Level 2.1 and LOCUS Level III, and Mindful Health runs it 3 hours a day, 3 to 5 days a week.

A PHP takes 20 or more hours a week. You still sleep at home, but it is hard to combine with a full-time job. It is ASAM Level 2.5 and LOCUS Level IV, and Mindful Health runs it 5 hours a day, 5 days a week.

Inpatient care runs around the clock in a hospital, and work or school stops for the stay. It is ASAM Level 4 and LOCUS Level VI. Mindful Health does not offer it, so in an emergency call 911 or 988.

Residential treatment sits between PHP and inpatient care. You live at a non-hospital facility, rated ASAM Levels 3.1 to 3.7 or LOCUS Level V. Mindful Health offers outpatient care, IOP and PHP. It does not run residential or inpatient units.

What is outpatient mental health care?

Outpatient care is scheduled treatment of under 9 hours a week while you live, work and study as normal. LOCUS Level II allows up to 3 hours a week of individual, group or family therapy, with a doctor’s review every 8 weeks.

At Mindful Health, outpatient care means individual therapy, psychiatry and medication management. It also covers two clinic treatments for depression that has not responded to medication: Transcranial Magnetic Stimulation (TMS) and Spravato (esketamine). Therapy and psychiatry run at six Texas clinics or by video for patients anywhere in Texas.

Outpatient care fits when you are safe, your symptoms are steady and you get through work, school and family duties most days. It stops fitting when the week between sessions feels too long. Missed workdays, broken sleep and a medication that has not helped are the usual signs. Our piece on when mental health symptoms become signals explains why medication alone often falls short and what the next step looks like.

What is an intensive outpatient program (IOP)?

An IOP is structured, mostly group-based treatment of 9 to 19 hours a week, and you sleep at home. Medicare sets the floor: a doctor must certify that you need at least 9 hours of services a week.

Mindful Health’s IOP runs about 3 hours a day, 3 to 5 days a week. That adds up to 9 to 15 hours, and you can attend at a Texas clinic or virtually. Days centre on group therapy. A first group session opens with a mood check-in and a short mindfulness exercise. Our walk-through of what to expect in group therapy covers group rules and the closing psychoeducation segment.

IOP fits mild to moderate symptoms that weekly therapy has not settled: depression, anxiety, panic, bipolar disorder or PTSD, in someone who stays safe between sessions. Mindful Health’s IOP typically runs 6 to 12 weeks, depending on progress, diagnosis and insurance.

Not sure you are there yet? Our checklist of signs you need an IOP lists five situations where weekly therapy has stopped being enough. Symptoms that disrupt work, relationships or sleep are one of them.

What is a PHP, or mental health day program?

A partial hospitalization program (PHP), often called a mental health day program, is 20 or more hours a week of daytime treatment with no overnight stay. Medicare treats it as a stand-in for a hospital admission. A doctor must certify that you need at least 20 hours of services a week and would otherwise need inpatient psychiatric care.

The ASAM Criteria Fourth Edition, released in 2023, renamed this level from “Partial Hospital” to Level 2.5, “High-Intensity Outpatient”. LOCUS places it at Level IV, with treatment at least 5 days a week.

Mindful Health’s partial hospitalization program meets 5 hours a day, 5 days a week, for 25 hours in total. Groups use cognitive behavioural therapy (CBT) and dialectical behaviour therapy (DBT), alongside psychiatry. It suits people whose symptoms weekly care has not controlled, people who made too little progress in IOP and people leaving inpatient care.

One test works for any program sold as a “day program”: ask for the weekly hours. Twenty or more is PHP. Nine to 19 is IOP, whatever the program calls itself.

What is inpatient mental health care?

Inpatient care is 24-hour treatment in a psychiatric hospital or a hospital psychiatric unit, for people who cannot stay safe at home right now. Staff watch safety around the clock and can adjust medication every day.

The aim is to stabilise you, then move you to PHP or IOP once you meet that level’s criteria.

Mindful Health does not run an inpatient unit. If you or someone you love is in danger now, call 911, call or text 988 (the Suicide & Crisis Lifeline), or go to the nearest emergency room. Our guide to suicide warning signs lists the verbal and behavioural signs that call for same-day action, and what to say to someone at risk.

Inpatient vs outpatient mental health: who decides the level?

A clinician decides, using a structured assessment that insurers also use to judge medical necessity, meaning whether a level of care is clinically justified. For mental health, the usual tool is LOCUS, the Level of Care Utilization System from the American Association of Community Psychiatrists. For substance use and dual diagnosis (a mental health condition plus a substance use disorder), it is the ASAM Criteria.

LOCUS scores six areas: risk of harm, functional status, medical and psychiatric co-morbidity, recovery environment, treatment history and engagement. Most scores add up to a total. Three can override it. A risk-of-harm score of 4 sets the level at V (residential), and a score of 5 sets it at VI (hospital). Functional status and co-morbidity follow the same rule, with one exception: a score of 4 does not force Level V when your home is low-stress and highly supportive.

That override explains why a sharp rise in safety risk can mean hospital care even when work and family are holding up. LOCUS training material states that the tool supports clinical judgement and does not replace it.

The ASAM Criteria Fourth Edition builds co-occurring care into the core standards for every level. A program at any level is expected to treat a mental health condition and substance use together.

Our position: start at the least intensive level that keeps you safe and functioning, and agree a step-down target in the first week.

How does step-down from inpatient work?

Step-down means moving to a less intensive level once you meet its criteria. Step-up is the reverse. Together they form the continuum of care, and the usual path out of hospital runs inpatient, then PHP, then IOP, then outpatient therapy.

The hours show why each step matters. A week in hospital is 168 hours of care. Mindful Health’s PHP drops that to 25. Its IOP drops it to 9 to 15. Weekly therapy is about 1 hour. We treat the steepest drop as the riskiest: going from PHP straight to weekly therapy removes 24 hours of support in a single week. A planned stretch in IOP keeps group support in place while you test your coping skills at home.

A step up is due when thoughts of self-harm become new, more frequent or more specific, or when you miss work, school or caregiving for days at a time. Rising drinking or drug use alongside low mood is another sign. So is no progress by your next treatment review; Medicare requires IOP reviews at least every 60 days.

You are ready to step down when symptoms have held steady since your last review and you use coping skills between sessions without prompting. Sleep, meals and work or school should be back on a routine, with an outpatient therapist or psychiatrist booked before discharge.

IOP vs PHP vs outpatient: which level do you need?

Five questions settle most cases, and a clinical assessment confirms the answer.

  1. Can you keep yourself safe tonight? If not, call 911 or 988, or go to an emergency room. That is inpatient care.
  2. Can you get through most of a workday or school day? If not, PHP is the usual match, even without a hospital stay first.
  3. Have weekly therapy and medication failed to settle your symptoms, while you still manage most days? IOP is the usual next step.
  4. Are your symptoms steady and your daily life mostly intact? Outpatient therapy or psychiatry fits.
  5. Is drinking or drug use part of the picture? Ask for a program that treats both together. Mindful Recovery treats adults with substance use and co-occurring mental health conditions in San Antonio, with Heath, Cypress and Georgetown listed as coming soon.

Diagnosis does not set the level. Two people with the same depression diagnosis can need different levels: one still working with family support at home, one who has stopped leaving the house.

Can you keep working, and what does insurance cover?

You can usually keep working through outpatient care and IOP, rarely through PHP, and not during an inpatient stay. A 3-hour IOP block fits around a shift. PHP’s 25 hours equal a part-time job.

The federal Family and Medical Leave Act (FMLA) gives eligible employees up to 12 workweeks of unpaid, job-protected leave in a 12-month period for a serious health condition. You qualify after 12 months with your employer and 1,250 hours worked, at a site with at least 50 employees within 75 miles.

Coverage checks tighten as hours rise, and Medicare shows the pattern. It has covered IOP since 1 January 2024. Medicare’s certification rules in 42 CFR 424.24 require a doctor to recertify IOP at least every 60 days, and PHP by day 18, then at least every 30 days. For hospital stays, Medicare’s inpatient mental health coverage page lists a 2026 Part A deductible of $1,736 per benefit period. Part A also caps stays in psychiatric hospitals at 190 days over your lifetime.

Mindful Health accepts many major insurance plans, including TriWest. Our intake team checks your benefits before your first appointment, so you know what your plan pays at the recommended level.

Which level of care fits a teenager?

Teens use the same levels, with school and family built into the plan. Clinicians often assess children and teens with CALOCUS, the child and adolescent version of LOCUS.

Mindful Health’s adolescent IOP and PHP programs serve ages 12 to 18, if still in high school. Teens live at home throughout. IOP leaves more of the day free for class. PHP runs in the daytime and changes the school day, so ask about school coordination before enrolling. Care can include family support and care coordination, and the team explains how updates reach parents while protecting the teen’s privacy.

Mindful Health also offers TMS for eligible teens aged 15 to 21 with major depressive disorder, in person only. Falling grades, school avoidance, withdrawal from friends and changes in sleep are reasons to ask for an assessment before a crisis forces the question.

The right level of care is the one that fits this week

The four levels sit on one scale: under 9 hours, 9 to 19, 20 or more, and around the clock. Choose by safety and daily functioning rather than diagnosis, and plan the step down before you start. A Mindful Health clinician can assess you or your teen, recommend a level and check what your insurance pays for it.

Request an assessment with Mindful Health or call (888) 877-6395. In a crisis, call 911 or call or text 988.

FAQs About Levels Of Care In Mental Health

How long does IOP or PHP last?

Mindful Health’s IOP typically runs 6 to 12 weeks, depending on progress, diagnosis and insurance. PHP has no fixed length either. Medicare requires a doctor to recertify PHP by day 18 and at least every 30 days after that. Your team reviews progress at each check and steps you down once you meet IOP criteria.

Can you go straight into PHP without a hospital stay?

Yes. Medicare defines PHP as care for people who would otherwise need inpatient psychiatric treatment, so it works as an alternative to admission. If an assessment finds you need 20 or more hours a week but can stay safe at home overnight, Mindful Health’s 25-hour PHP is a direct starting point.

Is residential treatment the same as inpatient care?

No. In the ASAM Criteria Fourth Edition (2023), residential care covers Levels 3.1 to 3.7 and takes place in a non-hospital facility where you live during treatment. Inpatient care is Level 4, inside a hospital, with daily medical management. Mindful Health offers neither; its levels are outpatient care, IOP and PHP.

Can you do an IOP online in Texas?

Yes. Mindful Health runs its IOP in person or virtually, about 3 hours a day, 3 to 5 days a week, for patients located in Texas. Virtual IOP works best with a private room and a stable connection. TMS and Spravato still need clinic visits, though the evaluation for both can start by video.
