Until now, SoonerCare members got to keep their insurance for 60 days after birth. But several pregnancy-related health problems — like heart conditions, postpartum depression and dental damage — last significantly longer than that.

The new policy allows members to stay enrolled for one year after delivery. It also increases the income cutoff, so more low-wage workers will qualify.

Secretary of Health Kevin Corbett notes one in five Oklahoma women of child-bearing age are uninsured, and the state consistently ranks among the worst for pregnancy-related deaths.

"Almost 12% occur past the six-week postpartum visit," Corbett said at a news conference Monday. "More than half of these deaths are preventable and are often related to chronic conditions such as diabetes, hypertension, mental illness and substance abuse or misuse."

The hope is extended coverage will curb deaths and keep new moms healthier.
