ASAM criteria denials: answering an SUD level-of-care decision dimension by dimension

What does an ASAM criteria denial usually say?

It names the ASAM Criteria and says the requested level, such as residential treatment, withdrawal management, PHP or IOP, is more than the documented risk requires. Many notices name the dimension the reviewer rated lower and the level they would approve instead; some cite only “ASAM,” with no edition, dimension or level.

Record the edition, each cited dimension and the level the reviewer found appropriate. Steps common to every level-of-care dispute are in the level-of-care denial guide.

• “Can be safely treated at a lower level of care,” often naming the level the reviewer would approve.
• Withdrawal can be managed without 24-hour monitoring.
• Low motivation or “not ready for change.”
• For continued stays: goals met, symptoms stable, or a safe environment to return to.

Which ASAM edition and dimensions did the reviewer apply?

Ask, because two editions are in use. ASAM published the third edition in 2013 and the fourth, for adults, in 2023. The fourth edition renamed and reordered the six dimensions and reorganized the levels of care, so a reviewer applying one edition to an assessment written in the other may be rating different things.

In the fourth edition, dimensions 1 to 5 drive the level-of-care recommendation, and Dimension 6, Person-Centered Considerations, is worked through with the patient in shared decision-making. Readiness to change, the third edition's Dimension 4, is now weighed within each dimension. Medically managed withdrawal management moved into the main continuum, which uses levels such as 2.1 intensive outpatient and 3.7 medically managed residential.

A fourth-edition volume for adolescents and transition-aged youth followed in 2026, and payers adopt editions on their own schedules; the Cigna and Evernorth guide shows editions applied by age.

How do you get the plan's ASAM version and the reviewer's rationale?

Ask in writing for the criteria the reviewer applied, including the edition and any plan guideline or software built on ASAM, plus the reviewer's notes and credentials. Employer plans must disclose mental health and substance use medical-necessity criteria on request, and on appeal must give free copies of documents relevant to the claim.

1. 01Check the notice: under 29 CFR 2560.503-1(g)(1)(v)(A), an employer plan's denial must include the criterion relied on or say a copy is free on request.
2. 02Request the criteria under 29 CFR 2590.712(d)(1) with the criteria request letter tool, and the claim file, including reviewer notes and dimension ratings, under 2560.503-1(h)(2)(iii) and (m)(8).
3. 03Ask whether the reviewer used ASAM's own text, a licensed ASAM-based tool, or a plan guideline that adds its own requirements.
4. 04For state-regulated plans, check state law: California plans must provide criteria at no cost, and Connecticut carriers must post theirs online.

Which laws require plans to use ASAM or similar nonprofit criteria?

No federal rule makes every plan use ASAM. Some states require it, or criteria from nonprofit professional associations, for the plans they regulate, and Medicaid SUD demonstrations commit states to SUD-specific placement criteria such as ASAM. Whether any of these applies depends on how the plan is regulated, so check the plan type first.

State laws reach the plans a state regulates, so confirm whether an employer plan is insured or self-funded before citing one.

• California (Health and Safety Code 1374.721 and Insurance Code 10144.52): state-regulated plans and insurers must apply the most recent criteria from the nonprofit professional association for the relevant specialty, and no different or more restrictive criteria for level-of-care decisions within that scope. Medi-Cal managed care contracts are excluded.
• Connecticut (General Statutes 38a-591c(a)(3)): substance use utilization review must use the most recent ASAM edition, or criteria the carrier shows the Insurance Department are consistent with it.
• Medicaid: CMS letter SMD #17-003 asks section 1115 SUD demonstrations for SUD-specific, multidimensional assessment such as the ASAM Criteria and an independent process for reviewing residential placements; check the state's demonstration.

What dated evidence answers each ASAM dimension?

Answer the dimensions the reviewer cited, and answer each with facts dated inside the disputed period: what was observed, by whom, on which day, and why the lower level cannot manage it. A cited dimension with no dated rebuttal leaves the reviewer's rating unanswered.

The level-of-care crosswalk tool sets each cited dimension against your evidence. When co-occurring mental health care is reviewed under LOCUS or CALOCUS-CASII, see the LOCUS and CALOCUS-CASII denial guide.

How should the multidimensional assessment be documented at admission and each review?

ASAM's implementation guidance calls for a standard assessment covering all six dimensions at entry and regular reassessment against its continued-service and transition criteria. Write each dimension in observable, dated terms, name the edition, explain why each less intensive level was ruled out, and update every dimension at each review.

Concurrent-review timing and same-day steps after a cutoff are in the continued-stay guide.

• Admission: all six dimensions with the facts behind each rating, the edition, and why each lower level was ruled out.
• Shared decision-making: under the fourth edition, the patient's preferences, barriers and the level they will engage in.
• Each review: what changed in each dimension since the last review, not copied-forward text.
• Payer contact: reviewer name, edition and dimensions cited, and what was asked next.

What is different about a withdrawal management (detox) denial?

Detox denials usually say withdrawal can be handled at a less intensive or ambulatory level. ASAM's alcohol withdrawal guideline says level of care should rest on current symptoms, the risk of severe or complicated withdrawal, and other dimensions such as environment, and that most severity scales should not decide level alone.

Check the edition: the third used separate withdrawal management levels (1-WM, 2-WM, 3.2-WM, 3.7-WM and 4-WM), while the fourth folds medically managed withdrawal into the main continuum. Then date and time the risk factors the guideline lists:

• Validated withdrawal scale scores, such as the CIWA-Ar for alcohol, with vitals and hours since last use.
• History of withdrawal seizures or delirium, and the number of prior withdrawal episodes.
• Medical illness, age over 65, and dependence on benzodiazepines or barbiturates.
• Other substance use, active psychiatric symptoms or suicide risk, and an unsafe home or low support.

How should a peer-to-peer go when the reviewer cites ASAM?

Have the treating physician lead, in dimension order, with dated facts for each dimension the reviewer rated lower. Open by confirming the edition, the cited dimensions and the level the reviewer would approve, and close by asking which specific fact would change the decision and how to send it.

Prep and call notes are in the peer-to-peer review guide. Then use the residential treatment appeal letter, or an expedited appeal if the patient is still in care and delay could seriously jeopardize their health.

• Use the reviewer's edition and dimension numbers, translating if your assessment used the other edition.
• Lead with the strongest risk: withdrawal history, overdose, failed lower-level care or an unsafe home.
• Answer “low motivation” with risk evidence from dimensions 1 to 5.
• If an employer plan upholds the denial, the appeal decision requires consulting a professional with appropriate training and experience in the field who was not consulted on the denial (29 CFR 2560.503-1(h)(3)(iii) and (v)).

Can you send Part 2 substance use records with an ASAM appeal?

Usually, with the right consent. Records from a program covered by 42 CFR Part 2 can go to a health plan with the patient's written consent, and since the 2024 rule a single consent can cover all future treatment, payment and health care operations disclosures. Each disclosure made with consent must carry the Part 2 notice.

Check that the consent names health plans or payers and has not been revoked, and send the notice with a copy or clear explanation of the consent (42 CFR 2.32). Send only pages that answer the cited dimensions; see the appeal packet guide.
