An Obamacare software glitch is now incorrectly tabulating how much people must pay for health insurance, according to a report from the Wall Street Journal.

“There’s a blanket acknowledgment that rates are being calculated incorrectly,” a senior health insurance executive told the WSJ. “Our tech and operations people are very concerned about the problems they’re seeing and the potential of them to stick around.”

Government officials, however, say they are not worried and promised the Obamacare insurance exchanges will be ready to go on October 1. “We continue working with [insurers] and we are confident that on Oct. 1, consumers will see accurate premium costs, including tax credits,” said Medicare spokesperson Brian Cook.

The group responsible for building the calculator application, CGI Group Inc., bagged an $88 million taxpayer-funded government contract, the largest of any contractor, reports the WSJ.

Late Wednesday, Obama officials admitted that the Obamacare exchanges pose so many “cybersecurity threats” that it is instituting a new “rapid response mechanism,” a call center to field consumer complaints. It has also produced a publication on how to “Protect Yourself From Fraud In The Health Insurance Marketplace.”

The Federal Trade Commission says it expects fraudsters and scam artists to use Obamacare to target victims. Analysts say Obamacare is primed and ready for massive online identity theft by con artists.

“There are people licking their chops and saying, ‘A sucker is born every minute,'” said Health Access California director Elizabeth Abbott.

Obamacare’s government health exchanges open in 10 days.
