Do the new MAGI standards mean that more children will move from CHIP to Medicaid?

No, the number of children moving from CHIP to Medicaid is not affected by the change to MAGI.

Under the law, those states that cover children ages 6-18 with incomes between 100% and 133% of the FPL in CHIP will be transitioning these children to Medicaid so that children under 133% of the FPL, regardless of their age, are eligible for the same coverage program (some states will continue to have different, higher income standards for younger children). The change to MAGI standards does not change the number of children who will move from CHIP to Medicaid.
