Avik Roy, the president of the Foundation for Research on Equal Opportunity, and a conservative health care analyst, cheered the bill on Twitter, saying, “If it passes, it’ll be the greatest policy achievement by a G.O.P. Congress in my lifetime.” The bill, he explained in an email, provides a mechanism for poor Americans to move from Medicaid coverage into the private market, a goal he has long championed as a way of equalizing insurance coverage across income groups.
States would continue to receive extra funding for Obamacare’s expansion of Medicaid to more poor adults, but only temporarily. After several years, states wishing to cover that population would be expected to pay a much greater share of the bill, even as they adjust to leaner federal funding for other Medicaid beneficiaries — disabled children, nursing home residents — who are more vulnerable.
High-income earners would get substantial tax cuts on payroll and investment income. Subsidies for those low-income Americans who buy their own insurance would decline compared with current law. Low-income Americans who currently buy their own insurance would also lose federal help in paying their deductibles and co-payments.
The bill does offer insurance subsidies to poor Americans who live in states that don’t offer them Medicaid coverage, a group without good insurance options under Obamacare. But the high-deductible plans that would become the norm might continue to leave care out of their financial reach even if they do buy insurance.
The battle over resources played into the public debate. Mitch McConnell, the Senate majority leader, said the bill was needed to “bring help to the families who have been struggling with Obamacare.” In a Facebook post, President Barack Obama, without mentioning the taxes that made his program possible, condemned the Senate bill as “a massive transfer of wealth from middle-class and poor families to the richest people in America.”
In another expression of Republican principles, the bill would make it much easier for states to set their own rules for insurance regulation, a return to the norm before Obamacare.
Under the bill, states would be able to apply for waivers that would let them eliminate consumer protection regulations, like rules that require all health plans to cover a basic package of benefits or that prevent insurance plans from limiting how much care they will cover in a given year.
States could get rid of the online marketplaces that help consumers compare similar health plans, and make a variety of other changes to the health insurance system. The standards for approval are quite permissive. Not every state would choose to eliminate such rules, of course. But several might.
“You can eliminate all those financial protections,” said Nicholas Bagley, a law professor at the University of Michigan. “That would be huge.”
Americans with pre-existing conditions would continue to enjoy protection from discrimination: In contrast with the House health bill, insurers would not be allowed to charge higher prices to customers with a history of illness, even in states that wish to loosen insurance regulations.
But patients with serious illnesses may still face skimpier, less useful coverage. States may waive benefit requirements and allow insurers to charge customers more. Someone seriously ill who buys a plan that does not cover prescription drugs, for example, may not find it very valuable.
There are features that would tend to drive down the sticker price of insurance, a crucial concern of many Republican lawmakers, who have criticized high prices under Obamacare. Plans that cover fewer benefits and come with higher deductibles would cost less than more comprehensive coverage.
But because federal subsidies would also decline, only a fraction of people buying their own insurance would enjoy the benefits of lower prices. Many middle-income Americans would be expected to pay a larger share of their income to purchase health insurance that covers a smaller share of their care.
The bill also includes substantial funds to help protect insurers from losses caused by unusually expensive patients, a measure designed to lure into the market those insurance carriers that have grown skittish by losses in the early years of Obamacare. But it removes a policy dear to the insurance industry — if no one else. Without an individual mandate with penalties for Americans who remain uninsured, healthier customers may choose to opt out of the market until they need medical care, increasing costs for those who stay in.
The reforms are unlikely to drive down out-of-pocket spending, another perennial complaint of the bill’s authors, and a central critique by President Trump of the current system. He often likes to say that Obamacare plans come with deductibles so high that they are unusable. Subsidies under the bill would help middle-income consumers buy insurance that pays 58 percent of the average patient’s medical costs, down from 70 percent under Obamacare; it would also remove a different type of subsidy designed to lower deductibles further for Americans earning less than around $30,000 a year.
Out-of-pocket spending is the top concern of most voters. The insurance they would buy under the bill might seem cheap at first, but it wouldn’t be if they ended up paying more in deductibles.
Mr. McConnell was constrained by political considerations and the peculiar rules of the legislative mechanism that he chose to avoid a Democratic filibuster. Despite those limits, he managed to produce a bill that reflects some bedrock conservative values. But the bill also shows some jagged seams. It may not fix many of Obamacare’s problems — high premiums, high deductibles, declining competition — that he has railed against in promoting the new bill’s passage.
