CHIP Enrollment: June 2013 Data Snapshot

Methodology. The data in this report reflect the number of children, including individuals covered under the unborn child option, enrolled in CHIP programs in each state. State CHIP officials provided data specifically for the months of December 2012 and June 2013States also were asked to review data in previous reports in this series and to update data as might be appropriate for previous periods. The data for this report were requested in November 2013; responses were returned by December 2013Data for specific states in reports issued by CMS may differ from data in this report. Beyond the “point-in-time” versus “ever-enrolled” counts described below, differences occur when states provide data for this report for a point-in-time other than the final day of a quarter, when states update enrollment counts, e.g., for retroactive eligibility of a Medicaid-expansion CHIP program.

The data in this report are “point-in-time,” meaning the number of individuals enrolled in a specific month, such as June 2013. A “point-in-time” count is distinct from the “ever-enrolled” count, which is provided in reports issued by CMS. The annual count of children ever-enrolled will always exceed the number enrolled at any point- in-time, as long as new enrollments and departures occur during the year. For example, the CMS CHIP annual report for the year ending in September 2011, shows a total of 7,970,879 children enrolled at any point in time and for any length of time during that FFY 2011. In contrast, the number of children enrolled in the month of September 2011 per data provided for this report (not reported here) was 5,419,887 or 68.0 percent remained enrolled in September. Recent experience shows that one-third of CHIP enrollees enrolled at any time during the year were not enrolled at the end of the year.

Net Change. The data collected for this report are net changes in enrollment across the program and within select eligibility groups, taking into account the net impact of children enrolling and disenrolling from the CHIP program. Because this data are not individual level data and states do not make a distinction between enrollment among current beneficiaries and new beneficiaries, it is not possible to determine from this data the number of children that left the program and the number that newly enrolled in a given time period, i.e., the churn within the program. For example, this data set cannot be used to determine how many of the 5.7 million beneficiaries enrolled in June 2013 had been enrolled in June 2012.
