What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: The patient’s parent has requested reimbursement and prospective authorization and coverage for residential treatment center services. The American Academy of Child and Adolescent Psychiatry (AACAP) and American Association for Community Psychiatry (AACP) have unified the Child and Adolescent Level of Care Utilization System (CALOCUS) and the Child and Adolescent Service Intensity Instrument (CASII) into a single instrument, the Child and Adolescent Level of Care/Service Intensity Utilization System (CALOCUS-CASII). This instrument is a standardized tool used to determine the intensity of services needed for children and adolescents, 6-18 years of age, presenting with psychiatric, substance use, medical and/or developmental concerns. Using CALOCUS-CASII, providers score patients on a scale of 1-5 using a six-pronged Dimensional Rating System.

Where the denial was upheld
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for Residential Treatment Center (RTC) services.At issue is whether the Residential Treatment Center (RTC) services at issue were 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 accordance with the generally accepted standards of mental health and substance use disorder care.(ii) Clinically appropriate in terms of type…
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for partial hospitalization program (PHP) services for 30 days.Findings: The physician reviewer found that American Association of Community Psychiatrists Level of Care Utilization System (LOCUS) provides a reliable framework for determining the appropriate level of care for adults needing mental health treatment. Using LOCUS, providers score patients on a scale of 1-5 using a six-pronged Dimensional Rating System. The six dimensions include: (1) risk of harm; (2) functional status; (3) medical, addictive and psychiatric comorbidity; (4) recovery environment (a. stressors and b. supports); (5) treatment and recovery history; and (6) engagement. The composite score is then used to determine the level of care needed.
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 anorexia nervosa, then check the rights and deadlines that apply to your plan.
