This is in addition to the $93.7 million it cost to build the non-functional website in the first place. From The Washington Times:
Officials at the Centers for Medicare and Medicaid Services, the agency that oversees the HealthCare.gov website, said the new contract requirements include functions that were not included in the initial launch.
The Centers for Medicare and Medicaid Services this year set aside $45 million in upfront payments to repair the website and reserved an additional $45 million to cover other anticipated costs. But Tuesday’s deal, valued at $31 million more than those two numbers combined, is based on an informed review of the federal exchange and its needs, officials said.
Note to the federal government, I would have gladly built a non-functioning website for half of that.
