Looks like gifts and inheritances will not be counted at all for MAGI.
NOTE: Gifts and Inheritances
Other common examples of “lump sums” are one-time gifts or inheritances. Gifts and
inheritances are NOT included in MAGI (because gifts and inheritances are taxed to
the donor or the estate, not to the receiver). Therefore, under MAGI rules for both
Medicaid and APTCs, gifts and inheritances will not be counted at all.
