If your program still documents admissions using the 3rd Edition’s six dimensions, the switch to the 4th Edition is probably already on your state’s calendar, if it hasn’t happened yet. ASAM published the 4th Edition of The ASAM Criteria in 2023. It rebuilt the multidimensional assessment that drives level-of-care placement, and states have been adopting it one at a time, each on its own schedule.
This guide goes dimension by dimension through what changed between the 3rd Edition, which plenty of programs still use, and the 4th. The point is practical. Get your intake forms, EHR templates and staff training updated before your state’s date arrives, not after a surveyor points it out.
What Is the ASAM Criteria, and Why Do the Dimensions Matter?
The ASAM Criteria is the framework most states and payers use to decide what level of care a person with a substance use or co-occurring condition needs. A diagnosis alone doesn’t answer that question. Clinicians assess the person across six dimensions covering things like withdrawal risk, physical health, psychiatric symptoms and the environment they’ll go back to, and that profile points toward outpatient care, residential treatment or something more medically intensive.
State Medicaid agencies tie reimbursement to it. CARF certifies residential levels of care against it. Surveyors read your assessments with it in mind. So when the dimensions change, your paperwork has a compliance problem the day your state adopts the new edition, and old dimension names on an intake form are one of the easiest findings a reviewer can write. If you’re not sure where your documentation stands, our free self-assessment is a quick first check. Running a residential program? The ASAM 3.7 readiness check goes deeper, including whether your assessment already uses the 4th Edition dimensions.
The Six Dimensions Under the ASAM Criteria, 3rd Edition
Many programs are still documenting against these:
- Acute Intoxication and/or Withdrawal Potential: a person’s past and current experience with substance use and withdrawal.
- Biomedical Conditions and Complications: health history and current physical condition.
- Emotional, Behavioral, or Cognitive Conditions and Complications: thoughts, emotions and mental health issues.
- Readiness to Change: how ready and interested the person is in changing their substance use.
- Relapse, Continued Use, or Continued Problem Potential: the person’s own history and risk around relapse or continued use.
- Recovery/Living Environment: the people, places and things around them that help or hurt recovery.
What Changed in the ASAM Criteria, 4th Edition
There are still six dimensions. Most have new names, several absorb pieces of old ones, and one is new:
- Intoxication, Withdrawal, and Addiction Medications
- Biomedical Conditions
- Psychiatric and Cognitive Conditions
- Substance Use-Related Risks
- Recovery Environment Interactions
- Person-Centered Considerations
The biggest shift is what happened to Readiness to Change. In the 3rd Edition it was its own dimension and could push a placement decision by itself. In the 4th Edition it no longer stands alone. Readiness now feeds into clinical judgment across the other dimensions.
Its old slot went to Person-Centered Considerations, which captures barriers to care (social determinants of health among them) along with what the patient actually wants. Each dimension also now carries subdimensions that spell out specific assessment factors. That part hits documentation hardest. A form that simply renames the six headings will still miss what reviewers expect to find underneath them.
Side-by-Side: 3rd Edition vs. 4th Edition Dimensions
| 3rd Edition | 4th Edition |
|---|---|
| Acute Intoxication and/or Withdrawal Potential | Intoxication, Withdrawal, and Addiction Medications |
| Biomedical Conditions and Complications | Biomedical Conditions |
| Emotional, Behavioral, or Cognitive Conditions and Complications | Psychiatric and Cognitive Conditions |
| Readiness to Change | Folded into clinical judgment across other dimensions |
| Relapse, Continued Use, or Continued Problem Potential | Substance Use-Related Risks |
| Recovery/Living Environment | Recovery Environment Interactions |
| (no equivalent) | Person-Centered Considerations (new) |
State Adoption Timeline: When Does the 4th Edition Take Effect?
There’s no national effective date. Each state licensing authority and Medicaid agency sets its own, and they don’t always line up with each other.
- Illinois: IDHS/SUPR began issuing licenses reflecting 4th Edition levels of care on June 1, 2025, with July 1, 2025 as the official adoption date and the start of compliance monitoring. Existing organizations received updated licenses mapping their 3rd Edition level of care to its 4th Edition equivalent. The state’s transition page has the crosswalk.
- Washington: The Health Care Authority originally planned to move to the 4th Edition on January 1, 2026. The legislature then passed SB 5361 (Chapter 335, Laws of 2025), signed May 17, 2025, which pushed the deadline for Medicaid managed care organizations and carriers to January 1, 2028. The law also lets HCA and the Office of the Insurance Commissioner jointly decide not to use the criteria at all, so keep an eye on HCA’s ASAM page before you change your forms.
- Other states: Many are still working out their timelines. Medicaid managed care contracts, state licensing rules and CARF or Joint Commission survey expectations don’t always move together, so confirm your date directly with your state licensing authority.
Washington is a good reminder not to plan around a date you read once. They move.
What This Means for Your Facility’s Documentation and Staff Training
Whatever your state’s date turns out to be, three pieces of work take longer than people expect. Start them early.
Intake and assessment forms
Every paper or EHR intake form that uses the old dimension names needs the 4th Edition names and subdimensions, including Person-Centered Considerations. If your EHR vendor controls the template, ask now when their 4th Edition version ships. Some vendors are further along than others, and waiting on one is a bad reason to miss a state deadline.
Clinical staff training
Assessors and utilization review staff need more than a list of new names. They need to understand why Readiness to Change stopped driving placement, and how to document social determinants and patient preference so the note holds up in a chart review. A one-hour slide deck rarely gets people there. Have them practice on real, de-identified cases.
Level-of-care mapping
Some states are crosswalking existing 3rd Edition levels to new 4th Edition levels. Illinois, for example, converted Level 1 Outpatient to Level 1.5 Outpatient Therapy. Your utilization review notes and payer authorizations have to use the level names that are current in your state, or you’ll spend weeks on denials that have nothing to do with the care you actually gave.

Frequently Asked Questions
Do all states require the ASAM 4th Edition now?
No. Adoption is state by state. Illinois adopted the 4th Edition effective July 1, 2025. Washington planned to move on January 1, 2026, then passed a 2025 law pushing its deadline to January 1, 2028. Many states have not published a final timeline, so confirm your state’s date with its licensing or Medicaid agency before changing your documentation.
What happened to Readiness to Change as a dimension?
It was removed as a stand-alone dimension. In the 4th Edition, readiness to change informs clinical judgment within the other dimensions instead of driving level-of-care placement on its own. Its place in the list went to the new Person-Centered Considerations dimension.
Is the 3rd Edition still acceptable?
Until your state moves to the 4th Edition, your state’s rules decide which edition you document against. Once it moves, 3rd Edition dimension names on your intake and assessment forms become a documentation finding waiting to happen.
Do we need to retrain all clinical staff on the new dimensions?
Yes. Anyone who conducts multidimensional assessments, makes level-of-care recommendations or completes utilization review documentation should be trained on the renamed dimensions, the new subdimensions and the Person-Centered Considerations dimension before your state’s effective date.
Will our CARF or Joint Commission accreditation require this update?
CARF has updated its ASAM Level of Care Certification rating elements for Levels 3.1, 3.5 and 3.7 to align with the 4th Edition, so certified residential programs are already measured against it. More broadly, accrediting bodies expect programs to document against current clinical standards, and as the 4th Edition takes hold in your state, surveyors will expect your assessments and treatment plans to reflect it.
Where can we get a clear picture of what our program needs to update?
Start with our free self-assessment for a quick baseline, then reach out through our services page for a direct review of your intake forms, EHR templates and staff training against the current ASAM Criteria dimensions.
Moving from the 3rd Edition to the 4th is more than a naming update. It changes how readiness to change is weighed and adds a dimension built around patient preference and social determinants of health. It also expects documentation down to the subdimension level. Programs that finish the work before their state’s date usually have a quiet transition. The ones that wait tend to find out from a survey finding.
