Levels of Addiction Care: From Detox to Outpatient

Medically reviewed by Bradley Tourtlotte, MD · Written by the Addiction Rehab Center clinical team · Last reviewed June 2026

Addiction treatment is not one thing — it is a continuum of care designed to match support to need and to step up or down as someone progresses. Understanding the levels can make the process feel less mysterious. This guide explains the main stages clinicians use, based on the American Society of Addiction Medicine (ASAM) framework. It is general education, not medical advice; a qualified clinician determines the right level through assessment.

Why levels of care exist

People come to treatment with very different needs. Some require around-the-clock medical supervision; others are stable enough to keep working while attending therapy a few times a week. Levels of care let treatment be intensive when it needs to be and lighter as someone stabilizes, which supports both safety and long-term recovery. Many people move through several levels over time.

Medical detox

Detox, or withdrawal management, clears substances from the body under medical supervision. It is the safest way to handle withdrawal, and it matters because severe alcohol or benzodiazepine withdrawal can be life-threatening and needs medical oversight. Detox treats physical dependence but is usually a starting point rather than complete treatment. Learn more on our alcohol detox page.

Residential and inpatient treatment

In residential care, people live at the facility and receive structured therapy, medical support, and a substance-free environment around the clock. It often suits those who need to step away from triggers or who have not found stability in less intensive settings. You can read more about NYSHIP residential treatment.

Partial hospitalization (PHP)

PHP offers a high level of structure — typically several hours of treatment most days of the week — while the person returns home or to sober housing at night. It is a common step down from residential care or a step up from outpatient when more support is needed.

Intensive outpatient and outpatient care

Intensive outpatient programs (IOP) provide several hours of group and individual therapy a week, letting people keep up with work, school, and family. Standard outpatient care involves less frequent sessions and often supports long-term recovery and relapse prevention. Explore NYSHIP outpatient treatment for details.

Stepping up and stepping down

One of the strengths of the continuum is its flexibility. People are not locked into a single level; care is meant to adjust as needs change. Someone might step down from residential care to PHP and then to outpatient as they stabilize, or step back up to a more intensive level if they hit a rough patch. A move to a higher level of care is not a failure — it is the system working as intended to keep you supported. Regular reassessment helps ensure the level of care still fits where you are.

Therapies and medication across the continuum

At every level, evidence-based therapies do much of the work — cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and motivational interviewing among them. Medication-assisted treatment with buprenorphine, methadone, or naltrexone can support recovery from alcohol or opioid use disorders. When mental-health conditions are also present, integrated dual-diagnosis care addresses them alongside substance use.

How NYSHIP covers the continuum

NYSHIP and the Empire Plan typically cover medically necessary care at each of these levels, though copays, network rules, and authorization requirements vary by plan and clinical need. A free, confidential benefits check can confirm what applies to you. You can review does NYSHIP cover rehab or start a benefits verification any time.
