NOTES:  *Coverage under the Medicaid expansion became effective January 1, 2014 in all states that have adopted expansion unless otherwise noted. Maine has adopted the expansion but is not included in the count of states that expanded through SPAs because it has not yet submitted a SPA to the federal government. Number of uninsured adults who would be eligible for Medicaid coverage if non-expansion states expand includes individuals currently in the coverage gap (<100% FPL), those who currently may be eligible for Marketplace coverage (100-138% FPL), and those who are currently eligible for Medicaid but not enrolled; US total is for all non-expansion states; state values may not sum to national total due to rounding. SPA: State Plan Amendment. CMS: Centers for Medicare and Medicaid Services.
