Leaving half the population behind-the continued fight to cover America's mothers: a call to action.

For the last century, healthcare coverage in the United States has been a debated topic. The passage of the Social Security Act Amendments and the Patient Protection and Affordable Care Act has improved the available coverage of vulnerable populations, but access to healthcare is still fraught with barriers. This is particularly true for women in the postpartum period. It is widely accepted that the postpartum period is the optimal time to address health issues that developed during pregnancy or predated pregnancy. With more than half of maternal deaths occurring in the year after a birth and disproportionately affecting women of color, the postpartum time period is critical. The United States is the only industrialized country with a rising maternal mortality rate and therefore must take advantage of the 12 months postpartum, or "fourth trimester," to aid in addressing this national health crisis. As an incentivized provision, most states have expanded Medicaid since the signing of the Patient Protection and Affordable Care Act. However, pregnancy-related coverage still ceases after 60 days postpartum. Although states can apply for a waiver to extend this coverage, this process is unnecessarily laborious. The time has far passed for the federal government to act. Presently, there are numerous pieces of legislation before Congress to provide Medicaid coverage for pregnant patients through 365 days postpartum. Insurance coverage alone will not reverse the rising maternal mortality rate in this country, but it is a crucial first step.
