H.R. 1909, the Preventing Maternal Deaths Reauthorization Act of 2025, extends and strengthens federal programs aimed at reducing maternal mortality across the United States. The bill reauthorizes funding for state-based maternal mortality review committees—groups that investigate pregnancy-related deaths to identify prevention opportunities—and requires these committees to include obstetricians and gynecologists. It also directs the Centers for Disease Control and Prevention to share evidence-based best practices on preventing maternal deaths with hospitals, medical professional societies, and regional quality improvement groups at least once per year. The legislation increases federal funding from $58 million annually to $100 million per year for fiscal years 2025 through 2029, supporting these maternal health initiatives nationwide.
