According to a CMS report, Medicaid enrollment increased by nearly 9 million between October 2013 and the end of August 2014, boosting total enrollment in the low-income health program by 14.7%. The report showed enrollment in Medicaid and CHIP stood at 67.9 million at the end of last August, with 27.8 million children enrolled in both programs. The data showed a sharp contrast in enrollment trends among states that chose to expand their Medicaid programs under the ACA and those that opted out of the expansion. California, an expansion state, saw its Medicaid and CHIP rolls grow by more than 2 million between July to September 2013 and this August. Non-expansion states experienced growth in the single digits, such as Wisconsin, which grew less than 2%, and Texas, which grew less than 4%. South Carolina had the biggest gain, of 10.5%.
