Accenture has replaced CGI Federal as the lead contractor for the troubled Obamacare enrolment website, reports Reuters.
The enrolment site failed to work properly for millions of Americans when it was launched last October by the U.S. Centers for Medicare and Medicaid Services (CMS).

"As CMS moves forward in our efforts to help consumers access quality and affordable health coverage, we have selected Accenture to become the lead contractor for the HealthCare.gov portal, and to prepare for next year's open enrolment period," CMS told Reuters.
CGI Federal's contract was scheduled to end on Feb. 28 anyway, and the company confirmed to Reuters it was not being renewed.
Accenture's year-long contract is estimated to be worth around $90 million (£58 million).
David Moskovitz, chief executive of Accenture Federal Services, said: "Accenture will bring deep healthcare industry insight as well as proven experience in building large-scale, public-facing websites to continue improving HealthCare.gov."
