The most important lines in the CBO report
"Community-rated premiums would rise over time, and people who are less healthy ... 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."
What it means: In the states that get waivers from the ACA's pricing and benefit rules, people with pre-existing conditions could be priced out of the market. Those states would cover about one sixth of the population.
"People living in states modifying the [essential health benefits] who used services or benefits no longer included in the EHBs would experience substantial increases in out-of-pocket spending on health care or would choose to forgo the services."
What it means: CBO confirmed that premiums would go down in those states, which was one of the GOP's main goals — but the tradeoff is that people could pay more in other ways. Among the benefits that those states might eliminate: "maternity care, mental health and substance abuse benefits, rehabilitative and habilitative services, and pediatric dental benefits."
"CBO and JCT estimate that a few million people would buy policies that would not cover major medical risks."
What it means: In the states with the waivers, some people might buy plans that don't cover a lot — but those plans would be so skimpy that CBO doesn't count them as health coverage.
