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 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.

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.
