Abstract

Objectives: Hospital emergency departments (EDs) function as the safety net for patients with non-traumatic dental conditions (NTDCs). With the implementation of Medicaid expansion under the Affordable Care Act (ACA) many adults became eligible for dental benefits. We examined the impact of "early" Medicaid expansion in Minnesota on ED visits for NTDCs from 2008 (prereform) to 2014 (postreform). Methods: Data from the State Emergency Department Databases for Minnesota were analyzed for 2 years: 2008 and 2014. All individuals who presented to the ED with a dental problem were identified based on the International Classification of Diseases, Ninth Revision, Clinical Modification with a primary diagnosis of 520.0-529.9. Demographic variables including patient age, gender, and primary payer were examined. Results: Between 2008 and 2014 there was a 18.8 percent increase in the number of all non-dental ED visits and a 9.7 percent decrease in the number of NTDC visits. In that time period, young adults 18-26 years old showed a significant decrease (19.3 percent, P<0.001) in the number of NTDC visits. Conclusions: The Minnesota experience suggests that the increase in Medicaid dental benefits through the ACA has significantly decreased NTDC visits, especially among young adults who were eligible for a dependent coverage policy that extends parents' health insurance to age 26. To our knowledge, no previous study has reported on the impact of early Medicaid expansion on the rate of ED use for NTDCs.
