We apply a difference-in-regression-discontinuities design using administrative claims data. We find that the reform increased adolescents' inpatient care utilization. It also reduced out-of-pocket healthcare expenditures. This effect was larger among low-income households, facilitating income redistribution. However, the lack of evidence on health improvements and household consumption spending responses suggests that generous patient cost-sharing for adolescent healthcare may cause efficiency losses.
