The Obama administration will replace CGI Federal, its main IT contractor for the glitch-prone HealthCare.gov.

"CGI and the Centers for Medicare & Medicaid Services (CMS) have mutually agreed to complete work on CGI's contract for the Federally-Facilitated Marketplace (FFM), in line with the previously-scheduled February 2014 contract end date," Linda F. Odorisio, CGI's vice president of global communications, said in a statement Friday to CNBC.
