Background: The Affordable Care Act (ACA)-dependent coverage Provision (the Provision), implemented in 2010, extended family insurance coverage to adult children until age 26.
Objectives: To examine the impact of the ACA Provision on insurance coverage and care among women with a recent live birth.
Research design, subjects, and outcome measures: We conducted a difference-in-difference analysis to assess the effect of the Provision using data from the Pregnancy Risk Assessment Monitoring System among 22,599 women aged 19-25 (treatment group) and 22,361 women aged 27-31 years (control group). Outcomes include insurance coverage in the month before and during pregnancy, and at delivery, and receipt of timely prenatal care, a postpartum check-up, and postpartum contraceptive use.
Results: Compared with the control group, the Provision was associated with a 4.7-percentage point decrease in being uninsured and a 5.9-percentage point increase in private insurance coverage in the month before pregnancy, and a 5.4-percentage point increase in private insurance coverage and a 5.9-percentage point decrease in Medicaid coverage during pregnancy, with similar changes in insurance coverage at delivery. Findings demonstrated a 3.6-percentage point increase in receipt of timely prenatal care, and no change in receipt of a postpartum check-up or postpartum contraceptive use.
Conclusions: Among women with a recent live birth, the Provision was associated with a decreased likelihood of being uninsured and increased private insurance coverage in the month before pregnancy, a shift from Medicaid to private insurance coverage during pregnancy and at delivery, and an increased likelihood of receiving timely prenatal care.
