Cigarette smoking during pregnancy is an important cause of poor maternal and infant health outcomes in the population eligible for Medicaid. These outcomes may be avoided or attenuated by timely, highquality prenatal care. Using data from the Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System for the period 2004-10, we examined the effects of two optional state Medicaid enrollment policies on smoking cessation, preterm birth, and having an infant who was small for gestational age. We used a natural experiment to compare outcomes before and after nineteen states adopted either of the two policies. The first policy, presumptive eligibility, permits women to receive prenatal care while their Medicaid application is pending. Its adoption led to a 7.7-percentage-point increase in smoking cessation but did not reduce adverse birth outcomes. The second policy, the unbornchild option, permits states to provide coverage to pregnant women who cannot document their citizenship or residency. Its adoption was not significantly associated with any of the three outcomes. The presumptiveeligibility enrollment policy will continue to be an important tool for promoting timely prenatal care and smoking cessation.
