The study included children ages 13 to 17 who filled a new prescription for an antidepressant medication and who were continuously enrolled over the study period. A new prescription was defined as a prescription fill with no antidepressant prescription fills in the prior three months. The percentage of children receiving any psychotherapy in the six months after the index prescription was calculated by using CPT codes for psychotherapy (90804—90824, 90826—90829, 90843—90849, 90853, 90855, 90857, M0064, H004, and H1011).
