What the insurer actually argued
| Reason given | Decisions | Overturned |

Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 3 | 33.3% |
What the reviewers wrote
Where the denial was overturned

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 substance use disorder, then check the rights and deadlines that apply to your plan.
