But it is unclear if Edwards is simply following through on campaign promises or trying to build a political portfolio for a possible bid for the presidency.
Edwards is sponsoring the Bipartisan Patient Protection Act, commonly called the patients' bill of rights, along with Sen. John McCain, R-Ariz.
In recent months several media outlets have speculated that Edwards is eyeing a run for the presidency in 2004.
But pundits point to the Democratic senator's lack of political experience as a potential liability. The former Raleigh lawyer was elected to the U.S. Senate in 1998 without having held an elected office.
But in a recent issue of Time Magazine, McCain showered praise on Edwards. "A lot of charisma," McCain told Time. "His honesty becomes apparent."
Democratic political consultant James Carville, who worked on Bill Clinton's campaign and in the White House, also praised Edwards. "A real thoroughbred," Carville said in the Time article. "He's got the touch."
The Time article also speculates that Edwards is trying to make a mark for himself through the patients' bill of rights legislation.
Under the proposal, patients would be able to seek the advice of medical specialists, gain direct access to pediatricians, obstetricians and gynecologists, and go to the nearest emergency room without being penalized by their HMO.
Jerome Maddox, an assistant political science professor at the University of Pennsylvania, said he thinks Edwards would make a solid presidential candidate but also pointed to his lack of political experience.
