California Gov. Gavin Newsom signed a new law on Tuesday to make abortions cheaper for people on private insurance plans, the first of more than a dozen bills the state’s Democratic leaders plan to pass this year to prepare for a potential U.S. Supreme Court ruling that could overturn Roe v. Wade.

The new conservative majority on the U.S. Supreme Court is weighing whether to overturn Roe v. Wade, the landmark 1973 ruling that banned states from outlawing abortion.

If they do, at least 26 states are likely to either ban abortion outright or severely limit access, according to the Guttmacher Institute, a research and policy organization that supports abortion rights.

That would force many women to travel to other states to get abortions, prompting Democratic-led states like California to propose and pass new laws to prepare for them.

Last week, Democratic Washington Gov. Jay Inslee signed a law aimed at banning legal action against people who aid or receive an abortion, a measure responding to the Texas law that lets people sue abortion providers or those who assist them.

Oregon lawmakers included $15 million in their state budget to help pay for people to travel to the state to get abortions.

California has a similar bill, one of 14 proposals aimed at expanding and protecting access to abortion in the nation’s most populous state. The bills were inspired by a report from the Future of Abortion Council, a group Newsom convened last year to advise him about how to respond if Roe v. Wade is overturned.

“We’re looking at 26 states that will introduce some sort of ban and restriction on abortion, so you have the other half of the country that will need to prepare for how we take care of those patients,” said Jodi Hicks, CEO and President of Planned Parenthood Affiliates of California. “We’re all imagining and trying to prepare correctly for what that impact will be.”

California already requires health insurance companies to cover abortions. But insurers often charge things like co-pays and deductibles that can add an average of $543 to the cost of a medication abortion and $887 to the cost of a procedural abortion, according to an analysis by the California Health Benefits Review Program.

The law Newsom signed on Tuesday eliminates those fees. While the law will make abortions cheaper, it will also slightly increase monthly premiums for patients and their employers.

But the savings from eliminating the fees will be greater than the increased premiums, according to an analysis by the California Health Benefits Review Program.

The law, authored by state Sen. Lena Gonzalez, makes California the fourth state to ban the fees — joining Illinois, New York and Oregon.

“As states across the country attempt to move us backwards by restricting fundamental reproductive rights, California continues to protect and advance reproductive freedom for all,” Newsom said.

The U.S. Supreme Court is expected to decide this summer whether to uphold a law in Mississippi that bans abortions after 15 weeks of pregnancy. During a public hearing on the case last year, a majority of justices indicated they were willing to uphold the law and even overturn Roe v. Wade.
