Statistical Enrollment Data System – States submit quarterly and annual CHIP statistical data to CMS through the SEDS automated reporting system (U.S. Department of Health and Human Services, Centers for Medicare & Medicaid Services, 2010, p. 47). Using forms provided by CMS, states report unduplicated counts of the number of children under age 19 who are enrolled in separate CHIPs and Medicaid expansion CHIPs. SEDS is a web-based system maintained by CMS since 2000 that collects new and total Medicaid and CHIP enrollment data from states on a quarterly basis. States must submit quarterly enrollment data within 30 days after the end of the fiscal quarter and aggregate annual data within 30 days after the end of the fourth quarter.46 This analysis uses quarterly and annual total enrollment data from three of the SEDS reporting forms and, to our knowledge, is the first analysis to do so.
