This study examines the effects of new and higher premiums on SCHIP enrollment in Kansas, Kentucky, and New Hampshirethree states that implemented premium changes in 2003. We used state administrative enrollment records from 2001 to 20042005 to track changes in total caseloads, new enrollments, and disenrollment timing in premium-paying categories of SCHIP before and after the premium changes were implemented. Premium hikes were associated with lower caseloads in all three states and with earlier disenrollment in Kentucky and New Hampshire. Premium increases appeared to have greater disenrollment effects for lower-income children in New Hampshire and for nonwhite children in Kentucky.
