Levels of Care for Addiction & Mental Health
Addiction and mental health treatment is not one thing. It is a continuum, and picking the right point on it is the single most important decision at the start of care — it drives your outcome, your schedule, and your cost. Here is how each level works and how clinicians decide.
The continuum of care, most to least intensive
Most people do not start at the top and stay there. A typical episode of care moves down one or two steps as symptoms stabilize, with each transition planned in advance.
- 1
Medically managed withdrawal (detox)
24-hour medical supervision, typically 3–7 days
Anyone at risk of dangerous withdrawal — alcohol, benzodiazepines, or high-dose opioids.

Inpatient & residential treatment
Live on site, typically 2–6 weeks
People who need to be away from their environment, or whose psychiatric or medical risk is too high for outpatient care.
Inpatient vs. residential treatment, compared - 3
Partial hospitalization (PHP)
About 25–30 hours a week, home each night
People stepping down from residential care, or who need daily structure without 24-hour supervision.
Partial hospitalization program in Alexandria, VA - 4
Intensive outpatient (IOP)
About 9–15 hours a week, evenings available
People holding down work, school, or family responsibilities who still need real clinical intensity.
Intensive outpatient program in Alexandria, VA - 5
Outpatient therapy & psychiatry
Weekly or biweekly sessions
People maintaining recovery, or whose symptoms are manageable with regular therapy and medication management.

Frequently asked questions
- What are the levels of care for addiction treatment?
- From most to least intensive: medically managed withdrawal (detox), inpatient or residential treatment, partial hospitalization (PHP) at about 25 to 30 hours a week, intensive outpatient (IOP) at nine to fifteen hours a week, and standard outpatient therapy and medication management. Most people move down through two or three levels during a single episode of care.
- Who decides which level of care I need?
- A licensed clinician does, using ASAM criteria for substance use disorders and comparable guidelines for psychiatric care. The assessment looks at withdrawal risk, medical and psychiatric stability, motivation, relapse history, and how supportive your living environment is. Your insurance plan then reviews that documentation for medical necessity.
- Can I start outpatient treatment without going to detox first?
- Often yes. Detox is required when withdrawal poses a medical risk — alcohol, benzodiazepines, and heavy opioid use most commonly. Many people begin directly in PHP or IOP. Our assessment determines this, and if withdrawal management is needed first we coordinate with trusted, vetted providers.
- How long does each level of care last?
- PHP commonly runs two to four weeks, IOP eight to twelve weeks, and outpatient therapy continues as long as it is useful. Length is clinical, not a fixed package, and insurance authorizations are renewed through concurrent review as your treatment team documents progress.
- Do you offer detox or residential treatment?
- We are an outpatient center offering PHP, IOP, virtual IOP, outpatient therapy, psychiatry and medication-assisted treatment. When someone needs detox or residential care, we refer to trusted, vetted providers and coordinate the step down back into our programs.
In-person PHP, IOP and outpatient programming is at our Alexandria, VA center, serving Virginia, Maryland, and Washington, DC. Virtual care is available to people located in Virginia. If you need help deciding, our insurance coverage guides explain what each plan pays at each level.
