This paper uses the 2014-2015 Current Population Survey Annual Social and Economic Supplement to consider changes in medical out-of-pocket expenditures over 2013-2014.  This period covers the implementation of several provisions of the Patient Protection and Affordable Care Act (ACA), which aims to make healthcare services more affordable through improved access to health insurance, an increase in covered services, and limits on out-of-pocket spending.  The paper estimates changes in out-of-pocket spending on health insurance premiums and non-premium medical expenditures for individuals younger than age 65 and not reporting Medicare coverage over the 2013 and 2014 calendar years.  Results across all insurance types suggest that average premium expenditures remained stable and average non-premium expenditures decreased by $48.  Results vary by insurance type with the most pronounced effects for individuals with direct purchase coverage, including decreases in average premium expenditures of $592 and in average non-premium medical expenditures of $236.
