"If the president's health care law is too complex and costly for big businesses and insurance companies to figure out, American families deserve a break from it as well," he said in a statement, alluding to the law's individual insurance mandate and other controversial measures.
While the Supreme Court has upheld the law's constitutionality, and the electorate returned Obama to the White House for a second term knowing his signature legislative achievement, House Republicans have continued to make it an issue.
Republicans lawmakers have voted 40 times to repeal the law; and some have vowed to oppose any 2014 budget measure that includes funding for implementation of the law, even if it could mean a government shutdown.
The delay on some caps on consumer costs follows other steps by the administration to adjust implementation of the Affordable Care Act, including an announcement last month of a one-year delay on a requirement that employers with more than 50 employees to offer health insurance or pay a penalty.
For his part, President Obama has acknowledged the rocky road but insists everything is going according to plan.
"This is a big country, and the health care industry is massive and there are tons of providers. And so as we implement, there are going to be glitches," he said last month. "And we're just steadily working through all that stuff."
