Senate Republicans have unveiled a sweeping plan to overhaul the Medicaid program, with changes policy analysts warn could lead to even greater coverage losses and pain for hospital systems than the aggressive proposal passed by the House of Representatives last month.

Senate Republicans on Monday proposed steeper Medicaid cuts than those included in the House-passed version of President Donald Trump’s signature policy bill—making the bill’s passage by the July 4 deadline set by Congressional Republicans even more uncertain as Medicaid cuts have been a major sticking point for some in the GOP.

The proposal would salvage some clean-energy tax credits and phase out others more slowly, making up some of the cost by imposing deeper cuts to Medicaid than the House-passed bill would.
