Objectives. We investigated how access to and continuity of care might be affected by transitions between health insurance coverage sources, including the Marketplace (also called the Exchange), Medicaid, and the Children's Health Insurance Program (CHIP). Methods. From January to February 2014 and from Augustto September 2014, we searched provider directories for networks of primary care physicians and selected pediatric specialists participating in Marketplace, Medicaid, and CHIP in 6 market areas of the United States and calculated the degree to which networks overlapped. Results. Networks of physicians in Medicaid and CHIP were nearly identical, meaning transitions between those programs may not result in much physician disruption. This was not the case for Marketplace and Medicaid and CHIP networks. Conclusions. Transitions from the Marketplace to Medicaid or CHIP may result in different degrees of physician disruption for consumers depending on where they live and what type of Marketplace product they purchase.
