Abstract
BACKGROUND: The Affordable Care Act (ACA) requires that privately insured women can obtain contraceptive services and supplies without cost sharing. This may substantially affect women who prefer an intrauterine device (IUD), a long-acting reversible contraceptive, because of high upfront costs that they would otherwise face. However, imperfect enforcement of and exceptions to this provision could limit its effect. STUDY DESIGN: We analyzed administrative data for 417,221 women whose physicians queried their insurance plans from January 2012 to March 2014 to determine whether each woman had insurance coverage for a hormonal IUD and the extent of that coverage. RESULTS: In January 2012, 58% of women would have incurred out-of-pocket costs for an IUD, compared to only 13% of women in March 2014. Differentials by age and region virtually dissolved over the period studied, which suggests that the ACA reduced inequality among insured women. CONCLUSIONS: Our findings suggest that the cost of hormonal IUDs fell to US$0 for most insured women following the implementation of the ACA. IMPLICATIONS: Financial barriers to one of the most effective methods of contraception fell substantially following the ACA. If more women interested in this method can access it, this may contribute to a decline in unintended pregnancies in the United States.
