The Supreme Court's decision upholding President Obama's health-care reform law may have cleared up some legal questions, but the landmark ruling does little to remove the uncertainty that has been hovering over the industry and the broader economy about the looming regulations.

That's because it's still not clear what the final picture of health reform will look like, especially as Republican lawmakers press ahead with their fight to either repeal or defund the Affordable Healthcare Act, or Obamacare.

"Short of spiking the whole thing down, I always thought that's how it would be. There's very little that's been changed by the Supreme Court from that perspective," said Douglas Holtz-Eakin, former director of the Congressional Budget Office and an opponent of the legislation.

New Rules Loom

Even though they don't know whether efforts to amend, repeal or defund the ACA will be successful, companies in the health-care sector have to press forward with crafting and putting into place new policies aimed at becoming compliant.
