he administration reversed course Friday and scaled back the release of personal information from HealthCare.gov, after The Associated Press reported that such details as consumers’ income and tobacco use were going to private companies with a commercial interest in the data.

The episode could become a blemish on what’s otherwise shaping up as a successful open enrollment season for the second year of expanded coverage under President Barack Obama’s health care law…

HealthCare.gov is used by millions to sign up for subsidized private coverage under the law, or to merely browse for insurance plans in their communities.

The latest changes by the administration mean that the website is no longer explicitly sending out such details as age, income, ZIP code, tobacco use and whether a woman is pregnant.
