The Trump administration will give states leeway to winnow down the mandatory health benefits guaranteed to consumers who buy Affordable Care Act insurance plans, under a rule issued Monday.

People who don’t have health coverage will also be able to get more exemptions from ACA penalties for going without insurance, according to guidance provided by the Centers for Medicare and Medicaid Services. Congress has repealed the penalty, but the move doesn’t take effect until 2019.

People who are opposed to abortion but can only select from plans that cover the procedure will be able to seek an exception and forego insurance without having to pay the penalty. The broader exemptions will be available immediately.

The changes to the ACA plans reflect the administration’s goal of dismantling former President Barack Obama’s signature health law and transferring more health-policy decisions to the states. Republicans say federal requirements on health policy and benefits have led to rising premium prices for people who buy their own insurance.

“Too many Americans are facing skyrocketing premiums that they can’t afford, and every year consumers are faced with the threat of fewer choices,” CMS Administrator Seema Verma said Monday.
