Maria, a 29-year-old mother from Houston, nearly missed her diabetes screening after giving birth—until she learned her Medicaid coverage wouldn’t end after two months. Like thousands of new mothers in Texas and New York, she stayed insured for a full year, giving her time to catch a condition that could have harmed her for life. A new study from Columbia University shows that extending Medicaid coverage to 12 months after childbirth has significantly increased follow-up care for women with serious pregnancy complications like diabetes and high blood pressure. These conditions raise the risk of heart disease, stroke, and even death later on, yet too many new mothers have historically fallen through the cracks when their insurance vanished just 60 days after delivery.
The research, published in Health Affairs Scholar, analyzed Medicaid claims from over five years of births in New York and Texas—two states with very different health systems but large low-income populations. It focused on women with diabetes in pregnancy (DIP) or hypertensive disorders of pregnancy (HDP), who need ongoing care to avoid long-term health problems. Before 2020, most lost coverage after two months, making it hard to attend check-ups or refill prescriptions. But when the pandemic brought continuous enrollment, care improved. Then, when Texas dropped that policy, follow-up visits dropped too. In contrast, New York’s switch to 12-month postpartum coverage in 2024 led to a clear rise in screenings and doctor visits.
The numbers tell a powerful story. In both states, women were more likely to get diabetes screenings and outpatient care when covered longer. Texas saw the biggest jump—likely because care rates started so low. Even prescriptions for blood pressure medications increased, though more modestly. The study included women on all types of Medicaid, including Emergency Medicaid in New York, showing the policy helped even the most vulnerable. With 49 states and Washington, D.C. now adopting the 12-month option under the American Rescue Plan Act, millions more mothers could benefit.
"Extending postpartum Medicaid coverage is an effective strategy to increase follow-up care among Medicaid beneficiaries," says Ellerie Weber of the Icahn School of Medicine at Mount Sinai, co-author of the study. The findings confirm what doctors have long argued: a single six-week check-up isn’t enough. The American College of Obstetricians and Gynecologists recommends ongoing care, and now there’s strong evidence that insurance coverage makes it possible.
As more states roll out the 12-month rule, the hope is that fewer mothers will slip through the cracks. For women like Maria, that extra time isn’t just paperwork—it’s a lifeline.
