What the reviewers wrote

Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.

Where the denial was overturned

Nature of Statutory Criteria/Case Summary: The patient’s parent has requested reimbursement and prospective authorization and coverage for inpatient (CALOCUS) provides a reliable framework for determining the appropriate level of care for adolescents needing mental health treatment. Using CALOCUS, 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) developmental, medical, substance use 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. Applying the CALOCUS framework, this patient meets the criteria for inpatient psychiatric level of care services.

Nature of Statutory Criteria/Case Summary: The patient’s parent has requested reimbursement and prospective authorization and coverage for inpatient psychiatric hospitalization 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.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for (1) risperidone (Risperdal), and (2) inpatient psychiatric hospitalization services for a minimum of 30 days and up to 90 days at a facility that specializes in paranoid schizophrenia with negative affect and bipolar disorder. In treating patients with psychosis, the determination of the antipsychotic and treatment plan should be in a shared decision making model between the patient and the clinical team. In this case, the patient has been noncompliant with and resistant to taking medications. Given that the patient’s current psychiatric treatment team is not recommending treatment with risperidone and the patient’s refusal of medications, the requested medication is not medically indicated.
