As high health costs persist, insurance affordability remains a challenge for many employers and individuals. However, allowing insurers to sell coverage across state lines could result in unintended consequences such as market segmentation that could threaten the viability of insurers licensed in states with strict benefit coverage, issue, or rating rules. The ability for high-risk individuals to obtain coverage could be compromised as a result. If rules governing insurance are consistent across the states, as they are under the ACA, market segmentation could be minimized. However, potential premium savings would also be minimal, as premiums would continue to reflect local health care costs, regardless of location of the insurer.
