Abstract

Oregon expanded Emergency Medicaid coverage to 60 days of postpartum care in 2018, facilitating ongoing care for conditions such as gestational diabetes. We linked Medicaid claims and birth certificates from 2010 to 2019 in Oregon and South Carolina, which did not expand postpartum care. We used a difference-in-difference design to measure the effects of postpartum care coverage among Emergency Medicaid recipients with gestational diabetes. Primary outcomes were receipt of recommended glucose tolerance testing and new diagnosis of Type 2 diabetes. Our sample included 2,270 live births among a predominantly multiparous, Latina population. Postpartum coverage was associated with a significant increase in receipt of a recommended glucose tolerance test (23.1 percentage points, 95% CI 16.9–29.3) and in diagnosis of Type 2 diabetes (4.6 percentage points, 95% CI 3.3–65.9). Expansion of postpartum coverage increased recommended screenings and care among Emergency Medicaid enrollees with pregnancies complicated by gestational diabetes.
