In the first three months of last year, 3.2 million new adults joined [Medicaid under the expansion provision of the Affordable Care Act], the CMS said in a report posted Jan. 23. Even though the agency has been releasing monthly reports on Medicaid enrollment for some time, those figures did not give a nuanced look at what effect the ACA was having on enrollment because they included children and re-enrollees. The report only tracks enrollment in states that expanded Medicaid as of March 2014, so Michigan, New Hampshire and Pennsylvania were not included. Also not included in the report were California, Washington, D.C., and North Dakota because the agency was still reviewing their data for accuracy. (Dickson, 1/26)

Under the private option, Arkansas uses federal funds to purchase private insurance for low-income residents. (1/26)
