About one-sixth of the population resides in areas in which the nongroup market would start to become unstable beginning in 2020. That instability would result from market responses to decisions by some states to waive two provisions of federal law, as would be permitted under H.R. 1628. One type of waiver would allow states to modify the requirements governing essential health benefits (EHBs), which set minimum standards for the benefits that insurance in the nongroup and small-group markets must cover. A second type of waiver would allow insurers to set premiums on the basis of an individual’s health status if the person had not demonstrated continuous coverage; that is, the waiver would eliminate the requirement for what is termed community rating for premiums charged to such people. CBO and [Joint Taxation Committee] anticipate that most healthy people applying for insurance in the nongroup market in those states would be able to choose between premiums based on their own expected health care costs (medically underwritten premiums) and premiums based on the average health care costs for people who share the same age and smoking status and who reside in the same geographic area (community-rated premiums). By choosing the former, people who are healthier than average would be able to purchase nongroup insurance with relatively low premiums.

CBO and JCT expect that, as a consequence, the waivers in those states would have another effect: Community-rated premiums would rise over time, and people who are less healthy (including those with preexisting or newly acquired medical conditions) would ultimately be unable to purchase comprehensive nongroup health insurance at premiums comparable to those under current law, if they could purchase it at all — despite the additional funding that would be available under H.R. 1628 to help reduce premiums.
