*The remake of the nation’s health-care system has hit a parliamentary snag in the Senate, and appears likely to be headed back to the House for one final vote before becoming law, a spokesman for Senate Majority Leader Harry Reid said.

The legislation makes a handful of changes to the sweeping health bill signed into law by Mr. Obama on Tuesday, including bolstering government subsidies to help individuals purchase health insurance and closing a politically unpopular gap in prescription drug coverage under Medicare, the health insurance for seniors.

Reid spokesman Jim Manley said Republicans have found two “minor” provisions in the bill that are likely to be subject to procedural challenges on the floor, and ultimately struck from the legislation. If successful as expected, the Republican challenges would modify the bill, requiring it to be sent back to the House for consideration again.
