A Brief Overview of ASAM Criteria 4th Edition Updates

The ASAM Criteria is a publication that provides standardized guidelines for assessing the needs of patients suffering from substance use disorder and developing individualized treatment plans. It prioritizes multidimensional assessment, which takes many unique aspects of the patient’s life and needs into account, such as their specific diagnoses, psychological state, social circumstances, and resources. The 4th edition was published in 2023 in both digital and print formats. 

Levels of Care Assessment

The ASAM Criteria describes four levels of care: outpatient, intensive outpatient, residential, and inpatient. Based on patient assessment, the provider will identify which level of care is appropriate for their needs. This determination will then be regularly reassessed. Notable adjustments to the levels of care made in the 4th edition include:

• Eliminating Level 0.5, with early intervention methods described in a different section;
• Eliminating Level 3.3, instead prioritizing the fact that cognitive challenges should be addressed at every level of care;
• Withdrawal management services described in Level 3.2 becoming integrated with Level 3.5;
• Standards for recovery support service becoming integrated into every level of care;
• Requiring the capacity for co-occurring levels of care;
• Adding harm reduction as an element of individual care.

As mentioned, in order to determine what level of care is appropriate, the patient will need to undergo a level of care assessment. This involves an interview following a standardized guide, which as of the 4th edition integrates medically managed levels of care into the continuum and further emphasizes person-centered concerns. Furthermore, criteria have been rearranged and updated to improve the process and outcomes, and a level describing standards for long-term remission monitoring has been added. Following the level of care assessment, a treatment planning assessment will be implemented. 

Continuum of Care

As the name implies, the “continuum of care” represents a continuum of gradations of intensity within the levels of care, represented as decimal points. It also describes more specific types of care within each level. Levels of care described in the 4th edition of the ASAM criteria include:

• RR: Recovery residence
• 1.0: Long-term remission monitoring
• 1.5: Outpatient therapy
• 1.7: Medically-managed outpatient
• 2.1: Intensive outpatient (IOP)
• 2.5: High-intensity outpatient (HIOP)
• 2.7: Medically-managed intensive outpatient
• 3.1: Clinically-managed low-intensity residential 
• 3.5: Clinically-managed high-intensity residential
• 3.7: Medically-managed residential
• 4.0: Medically-managed inpatient

The 4th edition introduced long-term remission monitoring, as well as options for recovery residence in conjunction with outpatient levels of care. It also incorporated medical management for addiction, withdrawal, and comorbid conditions into the continuum of care. 

6 Dimensions

Assessment of patient needs are built around 6 dimensions, which, in the 4th edition, are further clarified by subdimensions that describe actionable factors for each dimension. The six dimensions and their subdimensions are as follows:

• Intoxication, withdrawal, and addiction medications

• Intoxication and associated risks
• Withdrawal and associated risks
• Addiction medication needs

• Biomedical conditions

• Physical health concerns
• Pregnancy-related concerns
• Sleep problems

• Psychiatric and cognitive conditions

• Active psychiatric concerns
• Persistent disability
• Cognitive functioning
• Trauma exposure and related needs
• Psychiatric and cognitive history

• Substance Use-Related Risks

• Likelihood of risky substance use
• Likelihood of risky SUD-related behaviors

• Recovery Environment Interactions

• Ability to function in current environment
• Safety in current environment
• Support in current environment
• Cultural perceptions of substance use

• Person-Centered Considerations

• Patient preferences
• Barriers to care
• Need for motivational enhancement

Many of these updated dimensions are the result of merging dimensions from previous editions, while the previous 4th dimension “readiness to change” was removed and a new 6th dimension “person-centered considerations” was added. 

Training

Training for the 4th edition ASAM Criteria is available through online courses on the ASAM website. BestNotes is hosted a webinar on August 20th, 2025 to review the ASAM changes. These courses can support clinicians in expanding their understanding of principles, applications, and use of the ASAM CONTINUUM software. Some sessions may be available free of charge. ASAM also offers 300+ training slides for the 4th edition ASAM Criteria by request. 

It is vital for clinicians to not only stay up to date with new editions of the ASAM Criteria, but also to ensure that everyone working in a facility is up to speed with new practices and workflows. Furthermore, it is important that any new programs are properly integrated with existing addiction treatment and behavioral health software.
