Under the 2025 One Big Beautiful Bill Act (OBBBA), many of these children may be at risk of losing their Medicaid coverage.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To estimate changes in oral health outcomes and health care costs associated with projected Medicaid coverage loss among US children.<\/jats:p>\n <\/jats:sec>\n \n Design, Setting, and Participants<\/jats:title>\n A stochastic decision-analytic microsimulation model was developed to project changes in oral health and economic outcomes associated with Medicaid coverage loss among US children aged 0 to 18 years over a 10-year horizon (2025-2034). Simulated population characteristics were informed by the nationally representative National Health and Nutrition Examination Survey (NHANES) 2013-2018. Sensitivity analyses evaluated uncertainty in policy magnitude and structural assumptions. All analyses were performed from July 25 to March 2, 2025.<\/jats:p>\n <\/jats:sec>\n \n Exposure<\/jats:title>\n Projected annual Medicaid disenrollment of 480\u202f000 children under the 2025 OBBBA from 2025 through 2034.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n Incremental incident caries events and emergency department visits for nontraumatic dental-related conditions, quality-adjusted life-years (QALYs), and health care costs.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The simulated cohort was based on 11\u202f696 NHANES participants aged younger than 19 years (mean [SD] age, 9.2 [0.1] years; 5778 [weighted percentage, 49.2%] females). Over 10 years, projected coverage loss was associated with 95\u202f799 (95% uncertainty interval [UI], 15 107-171 514) additional incident caries events, 27 084 (95% UI, \u221241 015 to \u221212 458) QALYs lost, and $86.5 million (95% UI, $47.1-$125.1 million) in additional health care costs in the base-case scenario. Across alternative policy impact scenarios, incremental caries events ranged from 54 051 (95% UI, \u22125354 to 111 084) to 161 231 (95% UI, 58 630-261 271), and incremental costs ranged from $47.9 million (95% UI, $17.1-$77.6 million) to $145.8 million (95% UI, $92.5-$193.4 million).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In this decision-analytic microsimulation modeling study, projected pediatric Medicaid coverage loss was associated with worsening oral health outcomes and increased health care costs.
