On July 24, 2008, the House approved H.Res. 1388, which blocks for the remainder of the year a Medicare Modernization Act provision requiring Congress to consider Medicare funding legislation on an expedited basis if the Medicare Trustees estimate for two consecutive years that more than 45% of total Medicare spending will be derived from general revenues within a seven-year window. The Bush Administration had submitted legislation to Congress in February 2008 responding to the first such warning by the Medicare Trustees.
