Where the denial was overturned

Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for residential treatment center (RTC) services (ASAM 3.1). Per the American Society of Addiction Medicine (ASAM) criteria, this patient meets Level 3.1 criteria for RTC services.

Given these findings, the patient meets ASAM 3.1 requirements for this dimension.

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 psychodynamic psychotherapy up to three times per week. The 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.
