The Supporting Healthy Pregnancy Act of 2023 would require biological fathers to pay at least 50 percent of a mother's out-of-pocket medical expenses related to pregnancy and delivery through the child support system, but only if the mother requests such support. The bill amends federal child support requirements under the Social Security Act, meaning states would need to establish and enforce this obligation as part of their child support programs. The legislation specifically excludes abortion-related expenses from the definition of covered medical expenses. The changes would take effect on January 1 of the first calendar year following the bill's enactment, though states that need to pass new legislation to implement the requirement would have until the end of their next regular legislative session to comply. The bill does not establish new federal funding but would modify existing state child support enforcement obligations.
