This edition of the Five Slide Series estimates the amount each states’ residents are paying for the Medicaid expansion population’s coverage – whether or not their state is  participating in the coverage program.  In the aggregate, we estimate that an annual financial transfer of $17 billion is occurring from the residents of the non-expansion states to the residents of the expansion states.   A state not yet participating in the expansion can move its residents from collectively being large-scale net losers to a large-scale net gainers by opting to participate.
