The 2.3 percent tax on some devices sold by medical manufacturers was created under the Affordable Care Act. It is not set to take effect until 2020, following a move by lawmakers to include its postponement as part of the deal that ended a government shutdown in January. But lawmakers of both parties have long sought to repeal the tax, arguing that its enactment could lead to higher prices for consumers as well as the loss of tens of thousands of manufacturing jobs.
Fifty-seven Democrats joined 226 Republicans in approving the measure Tuesday night. The path forward in the Senate remains uncertain.
