Perinatal insurance coverage and behavioural health-related maternal mortality.

Increases in postpartum maternal deaths, including a substantial number associated with behavioural health conditions, are a public health crisis and have contributed to overall increases in maternal mortality. A leading hypothesis to explain this pattern suggests lack of availability or continuity of resources for behavioural health treatment after delivery, often secondary to lapses in insurance coverage. Extending postpartum Medicaid coverage through the first year postpartum could mitigate excess morbidity and mortality among postpartum individuals, particularly those with behavioural health conditions.
