Health care provider EmblemHealth has agreed to pay $575,000 to the state of New York to settle allegations that it inadvertently disclosed the Social Security numbers of more than 81,000 people.

According to the New York Attorney General’s Office, 81,122 EmblemHealth policyholders, including 55,664 New York residents, were sent a paper mailing with a label that included their Social Security number on it in October 2016. Normally, all mailings include a unique mailing identifier that is printed on the envelope, Attorney General Eric Schneiderman said in a press release announcing the settlement.
