Tennessee and South Carolina are joining five other states in extending health care coverage to women with low-to-modest incomes for a full year after childbirth, U.S. Health and Human Services Secretary Xavier Becerra announced on Friday.

The expansion of Medicaid and the Children’s Health Insurance Program comes as the U.S. Supreme Court could be poised to overturn women’s constitutional right to abortion. That could make the coverage more urgently needed than ever if more women, especially older women or those in poorer health, end up carrying pregnancies to term. In Tennessee, a trigger law would outlaw abortion in the state if Roe v. Wade were overturned. South Carolina has a law banning abortions after six weeks.

States are currently required to provide 60 days of coverage after childbirth, but medical experts say women can die from pregnancy-related conditions up to a year after giving birth and that most pregnancy-related deaths are preventable. Maternal mortality is particularly serious for Black women, whose pregnancy-related death rate is three times that of white women.

Asked about the effect of an abortion ban on Tennessee women at a Thursday news conference, Republican Gov. Bill Lee, who opposes abortion, pointed to the extension.

“It’s important that we recognize that women in crisis need support and assistance through this process. For example, that’s why we’ve expanded our postpartum coverage for women in TennCare,” Lee said.

TennCare is Tennessee’s version of Medicaid, the federal-state program covering about one in five Americans, from many newborns, to low-income adults and frail nursing home residents. The program pays for about four out of every 10 births in the United States.

About 700 U.S. women die annually because of pregnancy-related problems, a little over half after the woman has given birth, according to data from the Centers for Disease Control and Prevention. Nearly 12% of maternal deaths occur 43 to 365 days after delivery.

The expanded coverage is made possible by a provision in the COVID-19 relief bill that will expire after five years unless Congress reapproves it or makes it permanent.
