4th Edition - Print Version

The ASAM Criteria Fourth Edition is a comprehensive set of standards and decision rules that use a holistic, person-centered approach to determining the appropriate level of care and developing treatment plans for patients with addiction and co-occurring conditions.

The revised standards have been crafted using a rigorous methodology for scientific evidence review and consensus development. The result is an update that is easier to understand and apply for improved patient care.

New in this edition:

  • Color-coding system organizes information into easily identifiable sections, facilitating quicker access to key content
  • Redesigned charts and graphics distill complex concepts into simpler, clearer explanations
  • Updated clinical standards reflect the current state of scientific evidence and clinical practice, and integrate more person-centered considerations when assessing the level of care.

What’s new in The ASAM Criteria, Fourth Edition?

Core Components of The ASAM Criteria

The ASAM Criteria standards include three core components that work in tandem when making level of care recommendations. As a patient enters addiction treatment an ASAM Criteria Level of Care Assessment is used to identify the patient’s clinical needs. The results of the assessment are applied to the Dimensional Admission Criteria to determine the recommended level of care.

The ASAM Criteria also define standards for the different levels of care across the continuum, describing the setting, staffing, service intensity and other core elements at each level of care

As a patient moves through treatment, they are regularly reassessed. The transition and continued service criteria are applied to determine if the patient is ready to move to a less intensive level of care, requires a more intensive level of care, or should continue at the current level of care.



Updated Six Dimensions

The six dimensions of The ASAM Criteria were updated in the Fourth Edition. The Third Edition’s Dimension 4: Readiness to Change does not contribute independently to the recommended level of care; rather, it impacts clinical judgments related to risks in other dimensions and influences the services that should be delivered at any level of care and should be carefully considered in treatment planning.

The Fourth Edition reorders the dimensions such that consideration of readiness to change is integrated across dimensions and replaced by a new dimension, Dimension 6: Person-Centered Considerations. This new dimension considers barriers to care—including social determinants of health (SDOH)—patient preferences, and the need for motivational enhancement. The Fourth Edition also simplifies and updates dimension names to reflect the field’s evolving terminology and facilitate effective dissemination of these standards.

Newly Defined Subdimensions

The Fourth Edition describes subdimensions, reflecting core actionable factors, that should be assessed within each dimension. During the Level of Care Assessment, the subdimensions in bold and blue inform level of care recommendations and initial treatment for immediate needs; however, all subdimensions are considered for treatment planning purposes. Dimensions 1 through 5 are used to develop a level of care recommendation. When assessing Dimension 6, the assessor works with the patient using a shared decision-making framework to determine which level of care the patient is willing and able to engage in.

Updated Continuum of Care

The Continuum of care has also been updated in the Fourth Edition. The continuum still includes four broad treatment levels (1 through 4). And within these four broad levels of care, decimal numbers express further gradations of intensity and types of care provided. Major changes include:

  • Integration of medically managed levels of care – which provide medical management for intoxication, withdrawal management and biomedical and psychiatric comorbidities – into the main continuum of care. The continuum also includes programs with enhanced biomedical capabilities (ie, Level 3.7 BIO) to manage patients with medical comorbidities and enhanced capabilities to treat patients with co-occurring mental health conditions (ie, co-occurring enhanced [COE] levels of care, which include Levels 1.5 COE, 1.7 COE, 2.5 COE, 2.7 COE, 3.5 COE, 3.7 COE, and 4 Psychiatric).
  • A new Level 1.0 – Long-Term Remission Monitoring. This level of care provides long-term remission monitoring for patients in sustained remission, providing recovery management checkups and rapid reengagement in care when needed. This organization promotes a chronic care model of addiction treatment.
  • The Dimensional Admission Criteria may recommend a recovery residence in addition to an outpatient level of care (ie, Levels 1 and 2).

Fourth Edition Development

The Fourth Edition of The ASAM Criteria will be released in four volumes. Subsequent volumes will focus on adolescents and transition-age youth, justice-involved patients, and treatment of behavioral addictions (i.e., gambling, internet, and gaming addiction). The 4th Edition uses a rigorous methodology for evidence review and formal consensus development under the guidance of a new editorial subcommittee.  Learn More

ASAM Criteria Software

Three software tools are currently available to support the implementation of The ASAM Criteria, including:

  • ASAM CONTINUUM – a comprehensive electronic assessment tool that allows clinicians, counselors, and other staff to assess individuals with addictive substance use disorders and co-occurring conditions and leverage a computerized clinical decision support system (CDSS) to make level of care recommendations.
  • ASAM Co-Triage – a computer-guided provisional referral tool designed to generate an initial level of care placement for individuals with substance use problems.
  • The ASAM Criteria Navigator - ASAM has partnered with Optum to develop software for using The ASAM Criteria in utilization review and management workflows.



ASAM offers live and online courses designed to meet the learning needs of multiple audiences in making use of the ASAM Criteria. Take an ASAM course or work with one of our endorsed trainers.  Learn more
