The president said he would not rule out any ideas proposed in Congress, except any proposal that was "primarily funded through taxing middle class families".
He also said reshaping America's health care system was crucial to helping the broader economy, and that any reform would reduce rather than add to the US deficit.
Talking about the general economy, Mr Obama said the US had been "on the verge of a complete financial meltdown", but there was now "stabilisation".
"We've stepped away from the brink," he said, adding that "things would be even worse" without the government's financial bailout package.
Five congressional committees are currently working on healthcare bills, and although there is consensus on some aspects of reform, lawmakers are divided on whether to set up a public health insurance scheme for Americans without employer-sponsored coverage.
There is also much disagreement about how to raise revenue to fund the proposed expansion of healthcare coverage.
