ASAM (the American Society of Addiction Medicine) defines the canonical levels of care for substance-use treatment. Every payer UR reviewer, every state licensing rule, and every clinical placement decision references these levels. This is the ground-truth reference.
Placement at any level of care under ASAM is driven by an assessment across six dimensions. The same client can meet criteria for very different levels of care depending on which dimensions are most acute. Authorization decisions hinge on clinical documentation in each dimension.
ASAM levels span outpatient through hospital-level care. Each level is defined by the intensity of clinical services, the medical and nursing involvement required, and the residential vs ambulatory setting. The levels below are the standard reference language payer reviewers and accreditation surveyors will use.
Education and screening for individuals at risk of developing a substance use disorder but who don't yet meet diagnostic criteria. Often delivered in schools, primary care, employee assistance programs, and community settings. Not a billable treatment level for most commercial payers.
Traditional outpatient — individual and group counseling, typically less than 9 hours per week for adults (less than 6 for adolescents). For individuals with mild to moderate SUD who don't require structured programming. Includes Opioid Treatment Programs (Level 1-OTP) when methadone or buprenorphine is part of the treatment plan.
Structured day or evening programming, typically 9 to 19 hours per week for adults (6 to 19 for adolescents). Includes group therapy, individual sessions, family programming, and skills-based education. Best suited to clients with moderate severity who don't need 24-hour structure but need more than weekly therapy.
20+ hours per week of structured programming. Clients live at home or in supportive housing and attend programming during the day. Suited for clients stable enough to live independently or in a recovery residence but who need near-daily clinical intervention. Often the step-down from residential.
24-hour structured living with at least 5 hours per week of clinical services. Sober living-adjacent — emphasizes recovery skills, peer support, and accountability rather than intensive clinical intervention. Often used as a step-down from higher levels of residential or as a step-up from supportive recovery housing.
24-hour residential designed for adults with cognitive impairments, traumatic brain injury, or significant functional limitations. Programming is paced and structured to accommodate slower processing and learning. Less common than 3.5 in independent treatment settings.
The default level of care for what most operators and the public call 'rehab.' 24-hour residential treatment with intensive clinical programming, multiple groups per day, individual sessions, family work, and recovery skills. For clients whose recovery environment is destabilizing and who need separation from triggers to engage in treatment.
Medically monitored detoxification and stabilization. 24-hour nursing care with daily physician contact. For clients with significant withdrawal severity or co-occurring medical complications that don't require full hospital-level care. Often the entry point for clients with severe alcohol or opioid use disorders.
Full hospital-level care. 24-hour physician availability and ICU-capable nursing. For clients with life-threatening withdrawal, acute medical complications, or psychiatric instability requiring inpatient-level management. Typically delivered in hospital settings, not freestanding treatment centers.
Most commercial payers and many Medicaid plans require ASAM criteria documentation for initial authorization and continued stay reviews. The UR reviewer will be looking specifically for:
The ASAM Criteria 4th edition (2023) refined how levels are described and tightened how the dimensions tie to placement decisions. The most consequential changes for operators:
For an existing program, the 4th edition mostly changes documentation expectations, not staffing or facility requirements. Your policy and procedure manual and your treatment plan templates should reflect 4th edition language by your next accreditation survey.
