• As a result, CBO has also bumped up its estimates of how many Americans will be uninsured over the next decade — from 30 million to 34 million people.

Why now: Insurance premiums tend to go up every year, but the magnitude of these increases stems largely from the repeal of the ACA's individual mandate, the expansion of skimpy short-term plans, and the decision last year to cut off the law's cost-sharing payments.

What's next: Although the administration hasn't teed up any new policy announcements lately, senior officials from the Blue Cross Blue Shield Association told reporters yesterday that there's still reason to be nervous.

• It's too late to help moderate premium hikes for 2019, they said, so they're focused on 2020.
• They're hoping new policies like the change in short-term plans won't take effect until 2020, so that they won't upend the market assumptions plans have made for next year.
• "It continues to be uncertain times," said Justine Handelman, a BCBSA senior vice president.
