This bill, known as the "Moms Matter Act," establishes a significant grant program to address maternal mental health conditions and substance use disorders . The Secretary of Health and Human Services will award these grants to eligible entities, prioritizing those serving demographic groups with elevated rates of maternal mortality, severe maternal morbidity, and health disparities, especially in health professional shortage areas. Funds from this program can be used for various initiatives, including establishing or expanding maternity care programs that integrate mental and behavioral health services, offering group prenatal and postpartum care, and providing direct services and referrals for pregnant and postpartum individuals. The grants also support efforts to reduce stigma , raise awareness of warning signs, prevent suicide, and educate maternity care providers on identifying and referring individuals with mental health or substance use issues. A key focus is on improving coordination between maternity and mental health providers and developing information resources. Furthermore, the bill amends the Public Health Service Act to create a new grant program aimed at growing and diversifying the maternal mental and behavioral health care workforce . These grants will help establish or expand educational programs and schools that train providers specializing in maternal mental health and substance use disorders, including through scholarships. Priority will be given to entities that recruit and retain students and faculty from racial and ethnic minority groups and other underserved populations, and those that include bias, racism, and discrimination training in their curriculum. Both grant programs require annual reporting from recipients on their activities and outcomes, with the Secretary of HHS also mandated to submit comprehensive reports to Congress evaluating the effectiveness of the initiatives. The bill authorizes $25,000,000 annually for the maternal mental health equity grants and $15,000,000 annually for the workforce development grants, for fiscal years 2027 through 2031, to ensure sustained investment in these critical areas.
