Senate Majority Leader Mitch McConnell has committed to bringing the Graham-Cassidy bill to the floor of the Senate next week.
A vote must be taken by September 30 to pass the bill by simple majority through the budget reconciliation process.
It's uncertain whether the majority leader has the 50 votes necessary to pass the bill that would gut the mandates of the Affordable Care Act. Vice President Mike Pence would break a tie, but with only 52 GOP Senators, and the votes of four in question - Susan Collins of Maine, Lisa Murkowski of Alaska, Rand Paul of Kentucky and John McCain of Arizona - a failed vote would be another embarrassing defeat for the Republicans and President Donald Trump.
The Washington Post reported McConnell's intent to consider the Graham-Cassidy proposal next week.
Politico reported there would be a vote next week.
The Congressional Budget Office has said it would not have a full score of the bill by then.

Millions are expected to lose coverage under the bill that would fund individual insurance through block grants to states.
The bill partially repeals President Obama's signature healthcare law. It would leave in place ACA taxes and give the money as block grants.

It would get rid of Healthcare.gov, subsidies and tax credits for consumers and eliminate the individual and employer mandates.
It would allow states to waive coverage for essential health benefits.
Medicaid expansion would end and funding capped with payment equalized among states.
It would bar Planned Parenthood from getting Medicaid funding for family and reproductive health services for a year.
Providers, insurers, Democrats and some governors both Democratic and Republican, are opposed to the bill.
Procedure is that McConnell will bring the bill as an amendment to a House bill, according to Brookings Institution. If debate begins on Tuesday, a vote-a-rama is likely or Republicans could use procedural maneuvers to end the process, the report said.
On Monday at 10 a.m., the Senate Finance Committee is scheduled to hold a hearing on the Graham-Cassidy proposal.
