WASHINGTON — Women seeking abortions and some basic health services, including prenatal care, contraception and cancer screenings, would face restrictions and struggle to pay for some of that medical care under the House Republicans’ proposed bill.

The legislation, which would replace much of former President Barack Obama’s health law, was approved by two House committees on Thursday. Republicans are hoping to move quickly to pass it, despite unified opposition from Democrats, criticism from some conservatives who don’t think it goes far enough and several health groups who fear millions of Americans would lose coverage and benefits.

The bill would prohibit for a year any funding to Planned Parenthood, a major provider of women’s health services, restrict abortion access in covered plans on the health exchange and scale back Medicaid services used by many low-income women, among other changes.

Washington Sen. Patty Murray, the top Democrat on the Health, Labor, Education and Pensions Committee, said the legislation is a “slap in the face” to women. She said it would shift more decisions to insurance companies.

House Republican leaders said the bill, which is backed by President Donald Trump, will prevent higher premiums some have seen under the current law and give patients more control over their care.

The abortion restrictions and cuts to women’s health care could draw opposition from some Republican women.

Sens. Lisa Murkowski of Alaska and Susan Collins of Maine have both said that a prohibition on Planned Parenthood funding shouldn’t be part of the bill. Last month, Murkowski told the Alaska state legislature that she doesn’t believe that taxpayer money should go toward abortions but added, “I will not vote to deny Alaskans access to the health services that Planned Parenthood provides.”

Support from Collins and Murkowski will be crucial once the bill moves to the Senate, since there are 52 Republicans and the GOP will need 50 votes to pass it. A look at the bill:

Republicans have tried for years to block federal payments to the group. Now that Republican Donald Trump is president, they are adding the one-year freeze in funding.

Under Obama’s health law, health plans on the exchange can cover elective abortions, but they must collect a separate premium to pay for them so it’s clear that no federal funds are used. The GOP bill would go further, prohibiting the use of new federal tax credits to purchase any plan that covers abortions.

The bill would phase out the current law’s expanded Medicaid coverage for more low-income people that 31 states accepted, which is almost completely financed by federal funds. That could affect women’s health care services, including mammograms and prenatal care, for those who would lose that coverage. The legislation also repeals the requirement that state Medicaid plans must provide “essential health benefits” that are currently required, including pregnancy, maternity and newborn care.
