Preventing Maternal Deaths Reauthorization Act of 2023

This bill reauthorizes the Preventing Maternal Deaths program through 2028, extending existing provisions under the Public Health Service Act. It requires maternal mortality review committees to include obstetricians and gynecologists and improves death certificate accuracy by directing coordination with death certifiers. The Centers for Disease Control and Prevention must annually share evidence-based best practices for preventing maternal mortality with hospitals, state health groups, and perinatal quality collaboratives. The changes directly affect state maternal mortality review committees, healthcare providers, and hospitals receiving CDC guidance. The bill does not create new funding but extends the current program's authorization period from 2019-2023 to 2024-2028.
