WASHINGTON—The U.S. Senate has agreed to limit debate on legislation to retroactively extend federal COBRA health insurance premium subsidies and certain other expired tax code provisions.

The Senate’s 60-34 vote late Monday sets the stage for a final vote on the legislation, H.R. 4851, later this week.

Under the bill that the House already has approved, the 15-month, 65% federal premium subsidy would be extended to employees involuntarily terminated from April 1 through April 30.

The last short-term extension expired March 31.

Previously, as part of broader bill H.R. 4213, the Senate approved a longer extension to enable employees laid off through the end of the year to receive the COBRA premium subsidy, but the House has yet to take up that measure.
