A child who is not an unborn child, whose family income exceeds 150 percent of the poverty line, and who is ineligible under this section solely because of sub. (8) (b), or whose family income exceeds 300 percent of the poverty line, may obtain eligibility under this section if the difference between the child’s family income and 150 percent of the poverty line is obligated or expended on behalf of the child or any member of the child’s family for medical care or any other type of remedial care recognized under state law or for personal health insurance premiums or for both. Eligibility obtained under this subdivision during any 6-month period, as determined by the department, continues for the remainder of the 6-month period and extends to all children in the family.

For a pregnant woman to obtain eligibility under subd. 1., the amount that must be obligated or expended in any 6-month period is equal to the sum of the differences in each of those 6 months between the pregnant woman’s monthly family income and the monthly family income that is 300 percent of the poverty line. For a child to obtain eligibility under subd. 2., the amount that must be obligated or expended in any 6-month period is equal to the sum of the differences in each of those 6 months between the child’s monthly family income and the monthly family income that is 150 percent of the poverty line.
