Enactment of ambitious health reform laws in Massachusetts and Vermont in 2006 helped instigate a wave of state legislative activities to expand coverage to uninsured people. We identify thirty-nine states that have enacted laws in at least one access category since 2006. At least thirteen states have begun processes to enact comprehensive reforms to cover at least half of their uninsured residents. Key activities involve coverage expansions for uninsured children and for uninsured adults; regulatory changes in small-group and individual insurance markets; and individual and employer mandates. The future extent and durability of this wave are uncertain.
