The Trump administration issued a sweeping new rule on Tuesday to make it easier for small businesses to band together and set up health insurance plans that skirt many requirements of the Affordable Care Act, offering lower costs but also fewer benefits.

Covered California’s premiums are expected to rise significantly next year, but the head of the state’s insurance exchange said the Trump administration’s legal bid to dismantle protections for people with preexisting medical conditions will likely not contribute to the increases.

The American Academy of Actuaries has identified increasing health care costs and the effects of public policy changes as among the major drivers of 2019 premium rate changes for individual insurance coverage that is subject to Affordable Care Act (ACA) rules.

A federal appeals court on Thursday ruled that insurers are not entitled to collect billions of dollars they claim the federal government owes as part of an ObamaCare program.
