Here Is What's In The House-Approved Health Care Bill03:59

House Republicans approved their plan to replace the Affordable Care Act on Thursday.

Here's a rundown of key provisions in the American Health Care Act and what would happen if the Senate approves them and the bill becomes law.

Buying insurance

The bill would no longer require people to buy insurance through the marketplaces created by the Affordable Care Act, also known as Obamacare, if they want to use federal tax credits to buy coverage. It also would eliminate the tax penalty for failing to have health insurance coverage, effectively doing away with that requirement altogether.

In place of that mandate, the bill encourages people to maintain coverage by prohibiting insurance companies from cutting them off or charging more for pre-existing conditions as long as their insurance doesn't lapse. If coverage is interrupted for more than 63 days, however, insurers can charge people a 30 percent penalty over their premium for one year.

Tax credits

The House Republican plan would eliminate the income-based tax credits and subsidies available under the Affordable Care Act, replacing them with age-based tax credits ranging from $2,000 a year for people in their 20s to $4,000 a year for those older than 60.

That means some people will see their costs go up while others would pay less, depending on your age and where you live. This Kaiser Family Foundation interactive map shows how the change would play out across the country.

The map shows that a 27-year-old who makes $30,000 a year would see costs rise about $2,000 in Nebraska but fall by about the same amount in Washington state. A 60-year-old, however, would see costs rise almost everywhere, with increases of almost $20,000 a year in Nebraska.

Both Kaiser and the Congressional Budget Office found that, on average, older people with lower incomes would be worse off under the Republican plan than under the Affordable Care Act.

Tax cuts

The bill eliminates nearly all the taxes that were included in the Affordable Care Act to pay for the subsidies that help people buy insurance. Those cuts, which add up to about $592 billion, include a tax on incomes over $200,000 (or $250,000 for a married couple); a tax on health insurers and a limit on how much insurance companies can deduct for executive pay; and a tax on medical-device manufacturers.

Medicaid

The AHCA would make dramatic changes to Medicaid, the federal-state health program for the poor and disabled.

The Affordable Care Act allows states to expand eligibility for Medicaid to single, nondisabled adults with incomes slightly above the poverty line, with the federal government picking up most of the cost. That meant single adults who earn up to $15,800 a year could qualify in the 31 states, plus the District of Columbia, that expanded Medicaid. About 10 million people enrolled under that expansion.

The Republican plan would gradually roll back that expansion starting in 2019 by cutting the federal reimbursement to states for anyone who leaves the Medicaid rolls. People often cycle in and out of the program as their income fluctuates, so the result would likely be an ever-dwindling number of people covered.

The House bill also converts Medicaid from an entitlement program, in which the government pays all the health-related costs for those who qualify, to a grant program. The federal government would give states either a set amount of money for each Medicaid enrollee or let them choose to receive a fixed-dollar block grant.

The Congressional Budget Office estimated in March that the bill would cut Medicaid spending by $880 billion.
