"Putting a greater financial burden on older Americans is not the way to solve the problems in our health care system", LeaMond said.
Hardest hit by insurance losses would be low-income adults.
Those concerns were echoed by group after group, including AARP, the American Hospital Association, the American Academy of Family Physicians, the Association of American Medical Colleges and the March of Dimes. Cassidy has said the "test" is whether children in that situation would get the health care they need.
Republicans had one top priority for their health care bill: it had to lower insurance premiums.
As NPR's Danielle Kurtzleben reported, a 64-year-old making $26,500 would pay $1,700 in premiums annually under Obamacare. In the end, it estimated that around one-sixth of the population lives in states that would seek both of those waivers.
Acknowledging that it can't pinpoint which states might seek the waiver, CBO analysts project that one-sixth of the USA population reside in states that could choose not to cover essential health services and may opt to charge people with preexising conditions more in in premiums than healthy people. What might be similar is doing away with the Medicaid expansion program.
The CBO found that the AHCA will cut $834 billion from Medicaid over 10 years, which will cause 14 million Americans to lose coverage.
Other House Republicans also defended their bill, noting the CBO did find it would lower premium costs for younger and healthier people. Kevin Brady, R-Texas, the chairman of the House Ways and Means Committee.
But a bill that results in private- or public-sector coverage for fewer Americans is not a better way.
Though one-sixth of the US population may not seem like a lot, it equates to about 53.5 million Americans-and some public policy experts are saying that a single state's decision to adopt a waiver could have effects across state lines, weakening protections for people across every state.
But the CBO also acknowledges that its analysis includes some uncertainty, in part because the AHCA would allow states to get waivers that would exempt their insurers from many Obamacare coverage rules. The House bill allows states to opt out of the Affordable Care Act's ban on higher premiums for those with pre-existing conditions if they provide high-risk pools, with federal funding help. President Donald Trump, who made replacing Obamacare a key campaign promise in 2016, and other Republicans say it is too costly and creates unwarranted government interference in health care decisions. That would occur, the CBO said, because states could rescind the essential health benefits provision, meaning insurance companies could offer skimpier coverage plans.
As a outcome, the CBO and the JCT expect that the waivers in those states would have another effect: Community-rated premiums would increase over time, and people who are less healthy (including those with pre-existing or newly acquired medical conditions) would ultimately be unable to purchase comprehensive nongroup health insurance at premiums comparable with those under the PPACA.
"That's what we have to try to do is come up with options in our version of the bill that prevent those kind of outcomes", said Thune. First, the only real benefit of this legislation goes to the 1 percent and insurance and pharmaceutical industries that will receive $600 million in tax breaks.
