This bill, titled the Preventing Maternal Deaths Reauthorization Act of 2025, aims to strengthen efforts to reduce maternal mortality and morbidity across the United States. It reauthorizes and enhances federal support for State-based maternal mortality review committees , ensuring their continued operation and effectiveness. Key amendments include explicitly adding obstetricians and gynecologists to the clinical specialties represented on these committees and improving data collection by coordinating with death certifiers to enhance the quality of death records. Furthermore, the legislation mandates the Secretary of Health and Human Services, through the CDC, to regularly disseminate best practices on maternal mortality prevention to hospitals, State professional societies, and perinatal quality collaboratives at least once per fiscal year. Finally, it significantly increases the authorized funding for these programs to $100,000,000 annually for fiscal years 2025 through 2029, up from previous levels.
