Upgraded Health Site Faces Test

An updated version of HealthCare.gov now includes a window-shopping tool that could help the website withstand new pressures, including millions of people returning in coming months for insurance, federal officials said.

The window-shopping tool, which was added to the site Sunday evening, will let consumers see plans and premiums tailored to their needs before going through the process of signing up for coverage. The site is set to be relaunched in six days under a high degree of scrutiny from the public and lawmakers. Bottlenecks in the sign-up process, including verifying a consumer’s income and other personal information, were blamed for many of the site’s troubles in 2013.
