Over 71.6 million individuals were enrolled in Medicaid and CHIP in May 2015. This enrollment count is point-in-time (on the last day of the month) and includes all enrollees in the Medicaid and CHIP programs who are receiving a comprehensive benefit package.
509,082 additional people were enrolled in May 2015 as compared to April 2015 in the 51 states that reported comparable May and April 2015 data.
Looking at the additional enrollment since October 2013 when the initial Marketplace open enrollment period began, among the 49 states reporting both May 2015 enrollment data and data from July-September of 2013, more than 12.8 million additional individuals are enrolled in Medicaid and CHIP as of May 2015, more than a 22 percent increase over the average monthly enrollment for July through September of 2013. (Connecticut and Maine are not included in this count.)
