The Trump administration proposed new rules on Wednesday to stabilize health insurance markets roiled by efforts to repeal the Affordable Care Act, by big increases in premiums and by the exodus of major insurers. The move came a day after Humana announced that, starting next year, it would completely withdraw from the public marketplaces created by former President Barack Obama’s signature domestic achievement.

While Congress continues to struggle with how to “repeal and replace” the Affordable Care Act, the Trump administration today unveiled its first regulation aimed at keeping insurers participating in the individual market in 2018.

Humana announced on Tuesday that it would no longer offer health insurance coverage in the state marketplaces created under the federal health care law, becoming the first major insurer to cast a no-confidence vote over selling individual plans on the public exchanges for 2018.

A top House Republican on healthcare said Tuesday that lawmakers are looking to dramatically restructure Medicaid as part of an ObamaCare repeal bill.

National healthcare spending is projected to grow 5.6% annually over the next decade, according to a CMS report published Wednesday by Health Affairs.

The Affordable Care Act’s tax on high-cost employer health plans faced sharp opposition from employers and unions. Now, Republicans are drawing equal fire for ACA replacement proposals that those groups say would have some of the same effects.
