HealthCare.gov fixer Optum: 'Finished!'

Optum, the tech unit of UnitedHealth Group Inc. that was hired to repair the federal health insurance exchange after HealthCare.gov's disastrous launch two years ago, has declared its work complete. The Wall Street Journal reports that Optum's announcement this week comes as HealthCare.gov performed significantly better in its second sign-up period. The company was hired in October 2013 after the visitors endured long waits and major tech problems trying to sign up for insurance. Optum had worked on the original HealthCare.gov, but its software was one of the few bits that worked right from the start.
