What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement and prospective authorization and coverage for residential treatment center (RTC) services (ASAM 3.1). Per the American Society of Addiction Medicine (ASAM) criteria, this patient meets Level 3.1 criteria for RTC services. ASAM criteria focus on six dimensions to determine the appropriate level of care, which includes: (1) intoxication and withdrawal potential; (2) biomedical conditions; (3) emotional, behavioral, and cognitive conditions; (4) readiness to change; (5) relapse, continued use, or continued problem potential; and (6) recovery environment. For dimension 1, the patient did not have any symptoms of acute withdrawal after completing detoxification services and was being treated in Level 3.1 RTC. Given these findings, the patient meets ASAM 3.1 requirements for this dimension.

Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California external-review outcomes. Other state and federal programs have different eligibility rules, processes, and current availability; the rates here do not transfer to those programs or predict an individual result. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.
A diagnosis does not by itself establish treatment intensity. See the separate record for residential, PHP, IOP, inpatient, and withdrawal-management denials: behavioral-health level-of-care evidence guide.
These outcomes describe eligible cases completed through California DMHC’s Independent Medical Review program. They do not estimate the chance that an internal appeal, an external review in another jurisdiction, or your individual case will succeed. Use the record to identify evidence patterns involving opioid use disorder, then check the rights and deadlines that apply to your plan.
