What doctors think of the Obamacare replacement plan

Titled the American Health Care Act, the bill aims to repeal and replace the Affordable Care Act, overhauling the existing healthcare system.

The bill includes provisions such as allowing people with pre-existing conditions to keep their coverage, so long as they don't have a lapse in insurance.

By some estimates, up to 10 million Americans could lose their insurance under the AHCA. And the AHCA is already facing backlash from conservative Republicans who have nicknamed the bill "Obamacare 2.0."

Doctors' organizations, hospital groups, and patient advocacy groups are also not the biggest fans of the bill as it is. Here's what some of the major groups have said.
