Medicaid & CHIP Total Enrollment Chart - September 2018
The chart below displays the total number of individuals enrolled in Medicaid and the Children's Health Insurance Program (CHIP) in the current month and the period prior to the start of first Marketplace open enrollment period or “baseline” period (July – Sept. 2013). The total number of states that reported data for each period is also included. The enrollment figures are point-in-time counts (as of the last day of the month) and include only enrollees who received comprehensive benefit packages.
The September 2018 total enrollment figure above includes data from all 51 states. Among the 49 states reporting comparable enrollment data for both September 2018 and the July-September 2013 baseline period (CT and ME did not report baseline data), total Medicaid and CHIP program enrollment increased over the baseline period:
- By more than 27.1 percent for all states reporting
- By nearly 36 percent for expansion states that were covering newly eligible adults in September 2018
- By nearly 10 percent for non-expansion states
