2 Data & Methods We used data from the National Health Interview Survey (NHIS). 6 This survey, conducted annually, is nationally representative of the civilian noninstitutionalized U.S. population. The family core component collects information on every member of a sample household, including information on demographics, health characteristics and insurance coverage. The interviewed sample in 2013 consisted of 104,520 individuals. One adult and one child (ages 0-17) per household were randomly selected for the sample adult and sample child components. We compared cost barriers for five categories of health care services: (1) dental care, including check-ups (2) medical services, (3) mental health services, (4) prescription drugs and (5) eyeglasses. The dependent variable in the analysis was a binary variable based on the response to the following question: During the past 12 months was there ever a time when you needed [health care service] and didn t get it because you could not afford it? We examined trends in cost as a barrier to dental care for children ages 2-20, three non-elderly adult age groups (21-34, and 50-64) and elderly adults ages 65 and older. We also reported results for nonelderly adults by four levels of household income as defined in the NHIS: (1) less than 100% of the Federal Poverty Level (FPL), (2) % of the FPL, % of the FPL and (4) 400% of the FPL and higher. We tested for statistical significance across time using a chi-squared test. Our point estimates and statistical inferences take into account the complex survey design of the NHIS. Results Figure 1 shows the percentage of the population reporting cost as a barrier to obtaining needed dental care, medical care, prescription drugs, mental health services and eyeglasses. The trends over time were similar for all five services a fairly steady increase from 2000 to 2010, followed by a decrease from 2010 to Changes from 2000 to 2010 and from 2010 to 2013 were statistically significant. Changes between 2012 and 2013 for all health care services were not statistically significant. Figure 2 shows that from 2000 to 2010, the percentage of population who experienced cost barriers to dental care increased among all age groups, with the notable exception of children. From 2010 to 2013 cost barriers to dental care declined among both children and working-age adults. The percentage of adults ages reporting cost as a barrier to dental care fell from 17.1 percent in 2012 to 14.8 percent in 2013, the largest decrease of any age group. All of these changes were statistically significant. In 2013, young adults ages were just as likely as adults to report cost barriers to dental care. Young adults are no longer the age group with the highest level of cost barriers to dental care. Figure 3 shows trends for adults broken down by household income level. From 2000 to 2010, the percentage who could not obtain needed dental care due to cost increased among all income groups. From 2010 to 2013, it declined among all income groups. Both of these changes over time were statistically significant. However, changes from 2012 to 2013 were not statistically significant. 2

Discussion The percentage of the U.S. population reporting cost barriers to dental care continues to decrease, with young adults experiencing the most significant decline. While a full analysis of the underlying causes driving this improvement in the affordability of dental care is beyond the scope of this research brief, we offer some possible explanations. One important factor contributing to the overall decline in cost barriers to dental care could be changes in the actual cost of dental care. A recent analysis shows that dental care prices have grown at much lower rates in recent years and have increased less than the price of other health care services. 7 Policy changes at the national level that occurred between 2010 and 2013 may have contributed to the decline in access barriers due to cost. Maintenance of Effort (MOE) provisions enacted under the Affordable Care Act (ACA), which end for adults in 2014 and for children in 2019, helped to preserve ongoing coverage in Medicaid and CHIP. 8 The policy change could have reduced the percentage of low-income adults and children with cost barriers to dental care. The ACA s expanded dependent coverage provision is likely to have played a role in improving affordability of dental care for young adults. Since September 2010, the ACA has allowed young adults to remain on their parents private health insurance until age Although this policy does not apply directly to private dental benefits, a recent study reported that relative to the pre-reform period, private dental benefits coverage among adults increased in 2011 and 2012 as a result of the reform. 10 This dental benefits spillover effect also led to an increase in dental care utilization 4

5 and a decrease in cost barriers to dental care among young adults. While the improvements in affordability of dental care observed in the past few years are encouraging, cost still remains the most important reason for avoiding or delaying needed dental care. 11,12 Looking forward, up to 8.7 million children are expected to gain dental benefits by 2018 as a result of the ACA. 13 Up to 8.3 million adults are eligible to gain Medicaid dental benefits due to the Medicaid expansion. 14 In addition, through April 19, 2014 about 1.1 million adults and 88,000 children obtained private dental coverage through stand-alone dental plans in the new health insurance marketplaces, with an unknown number gaining dental coverage through private medical insurance. 15 Adults ages were by far the most likely age group to purchase dental benefits in the marketplaces. 16 This expansion of dental benefits coverage could further improve the affordability of dental care, although there is considerable uncertainty at this stage in the type of dental benefit plans being purchased in the health insurance marketplaces as well as the readiness of Medicaid programs in many states to absorb an influx of new beneficiaries. 17 Problems such as administrative burdens and low reimbursement rates may limit the number of dental providers that accept Medicaid. 18 Recent studies show that reforming Medicaid, including increasing reimbursement rates closer to market levels, is associated with an increase in dental care utilization. 19,20 The Health Policy Institute will continue to monitor barriers to needed dental care in the coming years.
