WASHINGTON -- The last-minute Senate Republican effort to repeal the Affordable Care Act would cost New Jersey $10 billion during its first six years, according to an independent study released Wednesday.

The study by Avalere Health said the loss to the state would grow to $112 billion from 2020, when the law would take effect, to 2036, 10 years after the federal health care block grant ran out under legislation sponsored by U.S. Sens. Lindsey Graham, R-S.C., and Bill Cassidy, R-La.

The legislation could increase the number of uninsured Americans by 32 million after 2026, according to the Kaiser Family Foundation, which studies health care.

"Graham-Cassidy does not change the fundamental cruelty of Trumpcare," said Rep. Frank Pallone Jr., D-6th Dist., the top Democrat on the House Energy and Commerce Committee.

"It is time for Republicans to abandon Trumpcare and to work with Democrats on bipartisan solutions to reduce costs and improve access to health care."

The last-ditch push comes as the Senate faces a Sept. 30 deadline to pass a repeal measure with just 50 votes rather than 60. That means lawmakers would have to vote with minimal hearings, little debate and no complete Congressional Budget Office analysis.

Meanwhile, independent studies show the current Affordable Care Act is working well in most places, and large rate hike requests are due primary to Republican repeal efforts.

Senate Republicans scrapped bipartisan legislation to fix problems with the existing law, and Rep. Josh Gottheimer, who as co-chair of the Problem Solvers Caucus led a similar effort in the House, said members of both parties should continue to work together.

"The American people deserve a bipartisan approach to fix our health care system, stabilize the individual marketplace and prevent premiums from rising," said Gottheimer, D-5th Dist.

President Donald Trump, who promised to leave Medicaid alone and to provide health care to everyone, endorsed the Senate Republican bill that breaks both campaign pledges.

In New Jersey, the cuts threaten the health insurance of 900,000 residents, according to New Jersey Policy Perspective, a progressive research group.

The bill would take the money that now goes for insurance subsidies and expanded Medicaid, cut $239 billion, and redistribute the rest to the states in such a way that those that enrolled more residents would get fewer federal dollars and those states that never expanded Medicaid would get more.

Individuals would no longer be required to carry insurance. Horizon Blue Cross Blue Shield of New Jersey the state's largest insurer, blamed the threatened loss of the mandate for contributing to its request for a double-digit rate increase.

States could seek waivers from federal requirements that insurers not charge more for pre-existing conditions and provide a minimum package of benefits including treatment for opioid addiction.

"The Graham-Cassidy bill would significantly reduce funding to states over the long term, particularly for states that have already expanded Medicaid," said Caroline Pearson, Avalere senior vice president. "States would have broad flexibility to shape their markets but would have less funding to subsidize coverage for low- and middle-income individuals."

New Jersey ranked 49th by getting back 38 cents for every $1 collected by the Internal Revenue Service from the state in 2015, according to the consumer website WalletHub. The Garden State is one of three states, along with Connecticut and Washington, that would lose $10 million 2020 to 2026, according to Avalere. Only five other states would lose more.

The cut would amount to 11 percent of New Jersey's health care funding from 2020 to 2026, expanding to 40 percent during the 2020-2036 period.

Indeed, nine of the 10 states listed by WalletHub as receiving the smallest amount from Washington per $1 in taxes collected, including New Jersey, would get less money.

Four of the 10 states with the best return on investment would get more federal health care funds, including Graham's home state of South Carolina, whose residents received $3.07 from Washington for every $1 collected in federal taxes.

Federal aid accounted for 27 percent of the Garden State's revenue in 2014, less than 38 other states, according to the Tax Foundation, a Washington research group.

Meanwhile, Mississippi, which received 40.9 percent of its revenue from Washington, more than any other state, would get an extra $6 billion under the Senate GOP bill.

The trade group for the health insurers came out against the Senate GOP proposal on Wednesday, saying it "would have real consequences on consumers and patients" in a letter from Marilyn B. Tavenner, president and chief executive of America's Health Insurance Plans.

The American Hospital Association's president and chief executive, Rick Pollack, said, "This proposal would erode key protections for patients and consumers and does nothing to stabilize the insurance market now or in the long term."

They joined the American Medical Association, New Jersey Hospital Association, American Cancer Society Cancer Action Network and AARP, the powerful seniors' lobby, are among the medical and patient groups that have called on the Senate to reject the latest repeal effort.
