It has been five years since the Affordable Care Act, better known as ObamaCare, was signed into law. The disastrous rollout of the federal marketplace website, Healthcare.gov, is well-known. According to a Bloomberg Government analysis released in September 2014, the cost of Healthcare.gov was more than $2 billion, more than twice the Obama administration’s estimates. Appropriately, the federal marketplace has been a subject of numerous congressional hearings.

But state-run websites have also squandered hundreds of millions of federal tax dollars. While the House Committee on Oversight and Government Reform has been investigating some of the problems with state-run websites, much more can and should be done. Every House and Senate committee that oversees healthcare issues should carefully examine the roles played by the Centers for Medicare and Medicaid Services (CMS), state officials and contractors in the design and implementation of the websites.

Other states experienced their own particular brand of exchange fiascos. Add Hawaii, Minnesota, New Mexico, Idaho, and Vermont to the list.

The Obama administration says it does not have contingency plans should the Supreme Court decide the IRS acted illegally and the subsidies must stop. But Chairman Joe Pitts (R-PA) of the House Energy and Commerce Health Subcommittee has information that suggests otherwise.

He said during a recent congressional hearing that he has learned of a 100-page document showing the Obama administration is preparing contingency plans should the Supreme Court invalidate the federal subsidies in King v Burwell.

HHS Secretary Sylvia Burwell repeatedly denied the existence of such a document, and says she has no legal way around the Supreme Court. “That’s why you’re not hearing plans” from the administration, Burwell told Pitts. “Because we don’t have the authority.” States should not count on a simple – or legal – solution from the administration.

Instead, governors would be well advised to work with members of Congress who are developing contingency legislation that would allow people to continue to get subsidies legally so they don’t lose their coverage – clearing through the jungle of bureaucracy created by ObamaCare and restoring decisions over health coverage to citizens.

At some point between now and the beginning of July, 2015, the Supreme Court will decide King v. Burwell. If the Court sides with the plaintiffs and invalidates the Internal Revenue Service (IRS) rule permitting federally facilitated exchanges to grant premium tax credits, the effects will be dramatic. Premium tax credits and cost-sharing reduction payments in the federally facilitated exchanges would probably cease at the end of July.

At that point, approximately 8 million Federally Facilitated Marketplace (FFM) enrollees currently receiving subsidies would have to decide whether to continue to pay the premiums themselves. Without the subsidies, their premiums would increase 122 to 774 percent depending on the state, with a national average increase of 255 percent. Millions of individuals would likely be unable to afford these premium increases and would cease paying their premiums. Their coverage would probably end 30 days thereafter.
