What the insurer actually argued
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 204 | 64.2% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 11 | 0% |
What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement and prospective authorization and coverage for intensive outpatient program (IOP) services.At issue is whether intensive outpatient program (IOP) services provided from 1/01/21 forward to treat the patient’s mental health or substance use disorder were, and are, medically necessary as defined in Health and Safety Code section 1374.72(a)(3)(A).California Health and Safety Code section 1374.72(a)(3)(A) states that “Medically necessary treatment of a mental health or substance use disorder” means a service or product addressing the specific needs of that patient, for the purpose of preventing, diagnosing, or treating an illness, injury, condition, or its symptoms, including minimizing the progression of that illness, injury, condition, or its symptoms, in a manner that is all of the following:(i) In accordanc…
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement and prospective authorization and coverage for prior residential treatment center (RTC) services (ASAM 3.5) and/or RTC services (ASAM 3.5) going forward. Per the Researchers criteria, this patient met and meets Level 3.5 criteria for RTC services for the time periods under review. ASAM criteria focuses on six dimensions to determine the appropriate level of care, which includes: (1) intoxication and associated risk, withdrawal and associated risks, and addiction medication needs; (2) biomedical conditions including physical health concerns and pregnancy-related concerns; (3) psychiatric and cognitive conditions and history including active psychiatric symptoms and persistent disability; (4) substance use-related risks including the likelihood of engaging in risky…
Where the denial was upheld
Nature of Statutory Criteria/Case Summary: The parent of an enrollee has requested authorization and coverage for Residential Treatment Center Services at a facility that offers and utilizes Cognitive Behavioral Therapy (CBT), Dialectical Behavioral Therapy (DBT), Eye Movement Desensitization and Reprocessing (EMDR), and medication management/psychiatry, for up to 6 months with the possibility of up to 12 months that can accommodate special education needs and that is appropriately qualified to treat autism and the enrollee’s other conditions.At issue in this case is whether any or all of the requested Residential Treatment Center Services at a facility that offers and utilizes Cognitive Behavioral Therapy (CBT), Dialectical Behavioral Therapy (DBT), Eye Movement Desensitization and Reprocessing (EMDR), and medication management/psychiatry, for up to 6 months with the possibility of up t…
Nature of Statutory Criteria/Case Summary: A patient has requested authorization & coverage for RTC services at a single RTC to treat patient’s multiple diagnoses (mental health & chronic pain) & a private room at an RTC. Per the ASAM criteria, this patient doesn’t meet Level 3.5 criteria for RTC services at a single RTC to treat patient’s multiple diagnoses. ASAM criteria focuses on six dimensions to determine the appropriate level of care: For dimension 1 (intoxication & withdrawal potential), patient meets ASAM 3.5 as patient didn’t experience any intoxication or withdrawal. For dimension 2 (biomedical conditions), patient meets ASAM 3.5 as the documentation supports that patient’s biomedical condition is not severe enough to warrant inpatient treatment but is sufficient to distract from treatment or recovery efforts.
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 anxiety disorder, then check the rights and deadlines that apply to your plan.
