To examine the impact of a Medicaid‐serving pediatric accountable care organization () on health service use by children who qualify for Medicaid by virtue of a disability under the “aged, blind, and disabled” () eligibility criteria.

Data Sources/Study Setting

We evaluated a 2013 Ohio policy change that effectively moved Medicaid children into an model of care using Ohio Medicaid administrative claims data for years 2011‐2016.

Principal Findings

Being part of the increased adolescent preventative service and decreased use of medications as compared to similar children in non‐ capitated managed care plans. Relative home health service use decreased for children in the .


Our overall results indicate that being part of an may improve quality in certain areas, such as adolescent well‐child visits, though there may be room for improvement in other areas considered important by patients and their families such as home health service.
