The change comes on top of $112 billion provided for the samepurpose in an earlier measure by Senate Majority Leader MitchMcConnell. That effort stalled two weeks ago due to a lack ofsupport from rival moderate and conservative Republicans.

The new measure, to be released to all Senate Republicans laterThursday morning, also discards earlier plans to repeal threeObamacare taxes on the wealthy, according to the summary. That moveeffectively freed up about $230 billion in cash to bolster healthexpenditures.

The revised bill also includes a provision that would allowpeople for the first time to use health savings accounts to payinsurance premiums, according to the document.

The taxes that will be retained include a net investment incometax on high earners and a Medicare surcharge on the wealthy. Thechanges also remove a tax break for health-insurance executives’pay.

McConnell of Kentucky is trying to find a narrow path to satisfymoderates within his party without alienating conservatives, whosupport deep spending cuts. Republicans on Wednesday said leadershadn’t told them yet which components of the U.S. health caresystem will benefit.

“I want to see how funds are used to help ensure that people canget access to affordable coverage, and that’s the key,” saidSenator Rob Portman of Ohio, who objected to McConnell’s originalbill. “But we don’t have the specifics."

Republicans are planning to include in the health bill a versionof an amendment proposed by Republican Senator Ted Cruz of Texasand GOP Senator Mike Lee of Utah, a person familiar with the plansaid.

Basic plans

Cruz and Lee want to allow insurers to offer cheap, bare-bonesplans alongside those that meet the more comprehensive coveragerequirements of Obamacare. Critics in both parties say the proposalwould essentially put people with pre-existing conditions in theObamacare insurance pool and allow young, healthy people to buycheaper plans in a separate pool.

But Lee wrote in a tweet Thursday morning that he hasn’t seenthe new language of the amendment added to the bill and is"withholding judgment."

Republican leaders asked the CBO to provide an analysis with,and without, the provision.

Cruz said Thursday he won’t vote to let the health bill advanceunless his proposal, or something very similar, is sent to the fullSenate.

“The bill will not have the votes to go forward if there are notmeaningful protections for consumer freedom that significantlylower premiums,” Cruz told reporters.

But health insurers have said the plan backed by Cruz woulddestabilize the insurance market and undermine protections for sickpeople. The BlueCross BlueShield Association called the Cruz plan“unworkable.”

America’s Health Insurance Plans, the industry’s main lobbyinggroup, said his proposal would hurt the market by dividing healthyand sick people into separate groups. The sick people, AHIP said,would face extraordinarily high premiums, or might not be able tofind coverage.

For the overall measure to pass, and Republicans to live upto their promise to eliminate President Barack Obama’s signaturedomestic accomplishment, they can lose no more than two GOP votesfrom their 52-48 majority amid unanimous Democraticopposition.

Bipartisan discussion

Without having seen McConnell’s latest plan, more than half adozen Republican and Democratic senators have discussedalternatives -- a bipartisan approach that would infuriateconservatives and probably would be a hard sell in the House, wherelawmakers in May passed their own plan to gut Obamacare.

After the bill is released and scoured by the CongressionalBudget Office, it will become clearer whether Republican leadershave found a balance between moderates’ desire for more spendingfor Medicaid and subsidies for Obamacare’s insurance exchanges, andconservatives seeking a smaller government role in health care.

“There’s a lot of different viewpoints, a lot of differentfeelings about it and they all have to be taken into considerationif you want to put together enough votes to pass the doggonething,” said Senate Finance Chairman Orrin Hatch, a UtahRepublican.

Paul objects

GOP Senator Rand Paul of Kentucky, a Tea Party stalwart, saidWednesday he will oppose the new measure and vote to block it fromfloor consideration -- without having seen the legislation. Thatmeans Republicans can lose support from only one more of theirmembers.

“The new bill looks a lot like the old bill except it spendsmore money, taxes more and does little to assuage the concerns ofconservatives,” Paul told reporters. “At this point, I cannotsupport the bill.”

As part of a drive to lure other support with more healthfunding, Republican leaders will retain several Obamacare taxincreases, a reversal from the earlier measure, according to a GOPaide familiar with the plan. That includes Obamacare’s 3.8 percenttax on net investment income for people who earn more than $200,000and couples with incomes over $250,000, as well as a 0.9 percentMedicare surtax on the same incomes.

The plan will also scrap a tax break for health-insuranceexecutives’ pay, the aide said, keeping an Obamacare provisionallowing health insurance companies to deduct from their taxes$500,000 of the pay of each top official. That’s a tougherrestriction than the limit imposed on other companies, which is $1million per executive.

Those changes are designed to address concerns of moderates,including Bob Corker of Tennessee and Susan Collins ofMaine, after Democrats and other critics said the earlier versioncut taxes for the wealthy at the expense of low-income and sickpeople. The three tax items produce a revenue stream of nearly $232billion over a decade.

Medicaid concerns

Collins said the Medicaid funding in McConnell’s earlierproposal, which the CBO said amounted to a cut of $772 billion fromcurrent projections over a decade, would hurt rural hospitals inher home state and others. Portman, whose home state of Ohio tookadvantage of Obamacare’s Medicaid expansion, is among thoseconcerned about funding levels and how the expansion is phased out.Corker is among those who want more generous subsidies for peoplebuying individual policies on insurance exchanges.

Republican leaders have considered boosting market stabilizationfunds for the exchanges. McConnell’s earlier proposal provided $50billion over four years to bolster insurance markets, in additionto cost-sharing subsidies to insurers covering lower-income people.It also included a state innovation pool of $62 billion over eightyears that would allow funding for high-risk pools, reinsurance andother items.

Republican leaders already have made clear the measure will havesome provisions demanded by some moderates, including $45 billionsought by Portman and Senator Shelley Moore Capito of West Virginiato address opioid addiction.

Meanwhile, the balancing act with conservatives is at least astough. Outside groups that promote small government and low taxes,including the Club for Growth and Tea Party Patriots, are keepingthe pressure on Republicans to simply repeal Obamacare and replaceit later.

“Failure is not an option,” said Jenny Beth Martin, presidentand co-founder of Tea Party Patriots. “This is what the votersvoted for them to do.”
