Key House and Senate health care leaders in both parties reached a deal on Sunday on legislation to protect patients from surprise medical bills. The deal between House Energy and Commerce Committee Chairman Frank Pallone Jr. (D-N.J.), Rep. Greg Walden (R-Ore.), the top Republican on that panel, and Senate Health Committee Chairman Lamar Alexander (R-Tenn.) is a step forward for the effort, which is seen as a rare area of possible bipartisan action this year.
