WASHINGTON, Nov 10 (Reuters) - Former President Bill Clinton visited the U.S. Capitol on Tuesday to urge Senate Democrats to quickly pass a broad healthcare overhaul, but a party leader said final action could spill into next year.

With the clock ticking on President Barack Obama's hopes of signing a healthcare bill by the end of the year, Clinton told Democratic senators it was economically imperative that they pass the long-delayed measure.

"People hire us to come to work in places like this to solve problems, to stand up and do it," Clinton, who failed in his own 1994 effort to revamp the healthcare system, said he told senators in the closed-door session.

"I just urged them to resolve their differences and pass a bill," he told reporters.

The overhaul has been stalled in the Senate for a month, but gained new urgency on Saturday when the House of Representatives passed a bill designed to extend coverage to most Americans and bar practices such as denying insurance to those with pre-existing conditions.
