Addiction treatment is not a one-size-fits-all process. It involves multiple stages of care, each designed to meet individuals at different points in their recovery journey.
This article outlines the main levels of care in addiction treatment and why understanding them is crucial for lasting recovery.
Level 0.5: Early Intervention Services
The levels of addiction care follow a structured framework recognized across the treatment field. One commonly used guideline is from the American Society of Addiction Medicine (ASAM), which outlines a continuum of services based on intensity and individual needs. Starting with Level 0.5, the continuum supports clients from early-stage intervention through the most intensive inpatient care.
This level targets individuals at risk of developing a substance use disorder but who do not yet meet diagnostic criteria. Early intervention services include screening, brief intervention, and referral to treatment when necessary. The goal is prevention—educating and intervening before the substance use escalates into dependence.
Level I: Outpatient Services
Outpatient treatment involves less than nine hours of structured programming per week for adults and is typically considered the first formal level of addiction care following early intervention. It is designed for individuals with mild substance use disorders or those transitioning from more intensive programs. Outpatient services provide a flexible, low-intensity structure that still offers essential clinical support.
Clients participate in services such as individual counseling, group therapy, relapse prevention education, and, when appropriate, family support. Because sessions are scheduled around personal obligations, outpatient care is ideal for those who need help maintaining recovery while continuing work, school, or caregiving responsibilities. It reinforces recovery skills in real-world environments and helps prevent relapse through ongoing accountability and therapeutic guidance.
Level II: Intensive Outpatient and Partial Hospitalization Services
Level II is divided into two subcategories and serves individuals who require more structured care than outpatient services but do not need 24-hour supervision
- Level II.1: Intensive Outpatient Program (IOP): Clients attend treatment for at least nine hours per week. The focus is on building coping skills, preventing relapse, and addressing co-occurring mental health issues. IOP is flexible and accommodates clients who need more structure than outpatient but do not require inpatient care.
- Level II.5: Partial Hospitalization Program (PHP): A more intensive option, PHP generally involves 20 or more hours of treatment per week. Clients may receive medical monitoring, psychiatric services, and comprehensive therapy. PHP is appropriate for individuals with more complex clinical needs but who are still stable enough to live at home.

Level III: Residential/Inpatient Services
Level III encompasses a range of inpatient treatment intensities. It’s intended for individuals who need a structured, live-in setting with round-the-clock support. This level often provides a critical bridge between outpatient treatment and medically managed care, delivering intensive therapy in a safe, stable environment:
- Level III.1: Clinically Managed Low-Intensity Residential Services: Best for individuals needing a stable recovery environment and structured support. Treatment often includes peer support and recovery education.
- Level III.3: Clinically Managed Medium-Intensity Residential Services: Designed for individuals with cognitive impairments or chronic relapse patterns. These programs emphasize repetition and slower-paced learning.
- Level III.5: Clinically Managed High-Intensity Residential Services: Intended for those with significant emotional, behavioral, or cognitive conditions. Programming is highly structured and addresses complex substance use and mental health challenges.
- Level III.7: Medically Monitored Intensive Inpatient Services: Offers 24-hour medical monitoring and nursing care. These facilities are staffed by licensed medical professionals and serve individuals with severe withdrawal risks or co-occurring conditions.
Level IV: Medically Managed Intensive Inpatient Services
This is the most intensive level of care, offering 24-hour nursing, continuous medical oversight, and daily physician visits. Delivered in hospital-based settings, it is intended for individuals experiencing life-threatening substance use disorders or severe co-occurring medical and psychiatric conditions.
Treatment at this level prioritizes immediate stabilization and medically managed detoxification, while also initiating therapeutic interventions. The goal is to achieve medical and emotional stability so the individual can safely transition to a lower level of care.
Continuum of Care and Step-Down Approach
Addiction recovery is not linear. Individuals often move through multiple levels of care as their needs change. A person may start at Level IV for detox, transition to residential treatment, then step down to IOP, and eventually outpatient services. This step-down approach ensures continuity and maximizes the chances of long-term success.
A professional assessment is critical in determining where someone should begin and how they should progress through treatment.
