US President Barack Obama has announced a one-year reprieve for millions of Americans facing cancellation of their health insurance policies under his embattled healthcare law.

He said insurers could extend individually purchased plans that would otherwise be cancelled.

The president had vowed Americans who liked their policies could keep them while pushing for the law's passage.

"We fumbled the rollout on this healthcare law," he said.

Growing impatience

In recent weeks insurance companies have sent letters to their customers announcing cancellation of coverage that does not meet the Affordable Care Act's strict new requirements for policies sold on the individual private market.

While Mr Obama said on Thursday that those people could keep their old plans, he encouraged them to shop around for better, more cost-effective coverage.

Under the change announced on Thursday, insurance companies that extend those plans will be required to inform customers of which medical care they do not cover, and inform them that other insurance options offering more coverage may be available.

Mr Obama also said he expected to have to "win back" credibility and the "confidence" of the American people in the wake of ongoing healthcare issues.

"I completely get how upsetting this can be for many Americans," particularly after his assurances that everyone who wanted to keep their plans would be able to, he said. "To those Americans I hear you loud and clear."

A 'burden'

Mr Obama acknowledged the flaws with the law's rollout had put a "burden" on his fellow Democrats.

The law has proven controversial, and Republicans have sought political advantage in every reported problem with the law.

The law, known to both sides as "Obamacare", is certain to be an issue in the 2014 mid-term elections.

The White House had previously said it was against proposals that would allow insurers to continue selling medical coverage that did not offer the level of benefits required under the law.

"The old individual market was not working well," Mr Obama said on Thursday. "And it's important that we don't pretend that somehow that's a place worth going back to."

Meanwhile, the Obama administration is still struggling to fix ongoing glitches with the healthcare.gov website, established by the law to enable consumers who do not get health insurance from their employers or from the government to shop for private plans.

Among other issues, the site has been plagued by long wait times to sign up for an insurance plan and serious flaws on the back end where customers' data are processed and sent to insurance companies.

The problems have proven so severe that fewer than 27,000 people in 36 US states have successfully enrolled in healthcare programs on the site since it launched on 1 October.

"Fewer people have signed up for Obamacare nationwide than the 280,000 who've already lost their plan in Kentucky as a result of Obamacare mandates,'' Senate Republican Minority Leader Mitch McConnell said.

Republican opposition

Democratic Congressman Mike Doyle told MSNBC on Thursday that his House colleagues had voiced "the frustration level that many of us have" to Mr Obama during their meeting.

The 1 October launch of the insurance marketplace websites run by the federal and state governments was the culmination of more than three years of political combat in Washington over the Patient Protection and Affordable Care Act, signed into law by Mr Obama in 2010.

The law establishes the healthcare.gov medical insurance marketplace website and others run by the states, bolsters coverage requirements, mandates that people carry insurance or pay a tax penalty, and offers subsidies to assist in the purchase of the insurance, among other provisions.

Republicans - who have long fought to undo the controversial healthcare law - have seized on Mr Obama's past pledges that people would be able to keep insurance plans they liked.

Some conservatives have gone as far as to accuse Mr Obama of lying to the public during his campaign for the law's passage.
