Nature of Statutory Criteria/Case Summary: Patient has requested reimbursement for residential treatment center (RTC) services & partial hospitalization program (PHP) services. The AACAP & AACP have unified the CALOCUS & CASII into a single instrument, the CALOCUS-CASII. This instrument is a standardized tool used to determine the intensity of services needed for children & adolescents, 6-18 years of age, presenting with psychiatric, substance use, medical &/or developmental concerns. Using CALOCUS-CASII, providers score patients on a scale of 1-5 using a six-pronged Dimensional Rating System: (1) risk of harm; (2) functional status; (3) co-occurrence of developmental, medical, substance use & psychiatric conditions; (4) recovery environment (a. stressors & b. supports); (5) resiliency & response to services; & (6) engagement. The composite score is then used to determine LOC needed.
