In comparison with the estimates for the previous version of the act, under the House-passed act, the number of people with health insurance would, by CBO and JCT’s estimates, be slightly higher and average premiums for insurance purchased individually—that is, nongroup insurance—would be lower, in part because the insurance, on average, would pay for a smaller proportion of health care costs. In addition, the agencies expect that some people would use the tax credits authorized by the act to purchase policies that would not cover major medical risks and that are not counted as insurance in this cost estimate.
