More from the CBO's analysis of the House GOP Health Care repeal bill (H.R. 2):
Under H.R. 2, about 32 million fewer nonelderly people would have health insurance in 2019, leaving a total of about 54 million nonelderly people uninsured. The share of legal nonelderly residents with insurance coverage in 2019 would be about 83 percent, compared with a projected share of 94 percent under current law (and 83 percent currently).
In particular, if H.R. 2 was enacted, premiums for health insurance in the individual market would be somewhat lower than under current law, mostly because the average insurance policy in this market would cover a smaller share of enrollees’ costs for health care and a slightly narrower range of benefits. The effects of those differences would be offset in part by other factors that would tend to raise premiums in the individual market if PPACA was repealed; for example, insurers would probably incur higher administrative costs per policy and enrollees would tend to be less healthy, leading to higher average costs for their health care.
Although premiums in the individual market would be lower, on average, under H.R. 2 than under current law, many people would end up paying more for health insurance— because under current law, the majority of enrollees purchasing coverage in that market would receive subsidies via the insurance exchanges, and H.R. 2 would eliminate those subsidies.
