How Narrow or Broad Are ACA Marketplace Physician Networks?

Health insurance companies often limit their number of in-network providers to minimize costs, negatively affecting patients’ choices, potential wait times, and continuity of care, especially when changing insurance plans. A 2023 survey found that 20% of consumers with marketplace plans were unable to access necessary services from in-network providers, highlighting concerns around the size and composition of provider networks. To increase access to care and address these issues, it is necessary to improve the clarity of information and the breadth of in-network providers.
