The busted ObamaCare websites cost a lot of people a lot of time. But for one Nevada man, problems with the state insurance exchange reportedly cost him $407,000.

The Las Vegas Review-Journal reported that Larry Basich, a 62-year-old Vegas resident, has been stuck with the massive medical bill despite signing up for an insurance plan via the state exchange last fall.

Basich, according to the article, selected a UnitedHealthcare plan in November, and even paid his first premium. But he never received confirmation that he was enrolled, despite being assured that he was by Nevada Health Link.

Amid the confusion, Basich suffered a heart attack at the end of December, and had to undergo a triple bypass. Now, according to the Review-Journal, no insurer will claim his bills -- and he's caught in a financially frightening battle as he appeals to the exchange and its contractor, Xerox, for help.

"All I wanted to do when I moved here was buy a house, get a dog and go to some spring training games for the Dodgers," Basich, who moved from Hawaii, told the newspaper.

Xerox reportedly tried to assign Basich's bills to another insurance plan, but that plan is refusing to accept them. Basich's insurance broker also complained that Xerox is spending a lot of time lawyering up and documenting all of Basich's communications.

"I believe Xerox is covering themselves because of a huge system error," broker Tamar Burch told the paper.

But Xerox reportedly says the company is trying to fix the problem. "Mr. Basich's issue is complex, and we're working on it every day," a spokeswoman told the paper.
