The purpose of this legislation is to improve the early detection and management of preeclampsia, a serious pregnancy-related condition that can lead to severe health complications for both mothers and babies. The law aims to ensure that states receive clear guidance on which screening tests for preeclampsia can be covered under Medicaid and the Children's Health Insurance Program (CHIP). Key provisions of the law require the Secretary of Health and Human Services to issue guidance within 180 days of the law's enactment.
