Testing of Healthcare.gov to be kept confidential

The new HealthCare.gov is set to open for broad testing by insurers on Tuesday, but they're not going to be publicly talking—or tweeting—about it. On Monday, the Centers for Medicare and Medicaid Services emailed insurers that it would require "all testers to acknowledge the confidentiality of this process to access the testing environment," according to a copy reviewed by The Wall Street Journal. The agency didn't require such an agreement of insurers last year ahead of the launch of HealthCare.gov, a CMS spokesman said. Last fall, early hints about the troubled launch of the federal marketplace emerged weeks before it went live on Oct. 1. Insurance executives and other sources noted possible problems.
