As lawmakers debated ways to trim the federal deficit and enact a fix to the tricky issue of physician Medicare payments last month, a coalition of hospitals and business groups took over two busy Capitol Hill subway stations with ads aimed at holding off a new round of hospital reimbursement cuts.

The Coalition to Protect America's Health Care, which the American Hospital Association helped to found in 2000, placed wall-to-wall ads in the Capitol South and Union Station Metro stops, the two busiest subway stations for Hill staffers and members of Congress.
