The Healthy Maternity and Obstetric Medicine Act aims to improve maternal and infant health outcomes by expanding access to affordable health coverage for pregnant individuals. It establishes a special enrollment period for pregnant individuals across various health insurance plans, including those offered through the Affordable Care Act Exchanges, group health plans, and the Federal Employee Health Benefit Program. This enrollment period begins upon reporting the pregnancy to the insurer or Exchange, or upon confirmation by a healthcare provider, ensuring timely access to care. Furthermore, the bill mandates that all group and individual health insurance plans providing dependent coverage must include comprehensive maternity care for all pregnant dependents, irrespective of their age. This provision ensures coverage for pregnancy, childbirth, and postpartum care, addressing a gap where young women might lack coverage. The legislation also strengthens Medicaid and CHIP provisions for pregnant and postpartum individuals. Specifically, it makes it mandatory for states to provide 12-month continuous coverage under Medicaid and CHIP for pregnant and postpartum individuals, moving from an optional to a required benefit. This ensures uninterrupted access to care throughout pregnancy and the critical postpartum period. The bill also requires states to maintain their Medicaid income eligibility standards for pregnant individuals and infants at or above their January 1, 2025 levels, removing previous upper limits. These changes are designed to reduce maternal mortality and improve health outcomes for mothers and babies, particularly addressing disparities in communities of color.
