Notes: Cases with ICD. 9. CM codes in more than one category (i.e., psychosis, dependence) have been assigned to a single category according to the order listed in the above tables. This approach undercounts the admissions involving rehab/detox (approximately 40% of all inpatient hospitalizations). These cases are captured under the psychosis, dependence, and abuse categories. All the codes used for the analysis are based on ICD.9.CM diagnosis codes except codes 94.64-94.69, which are procedure codes.
