Meta Platforms Inc. was sued over claims that private medical data is being shared secretly with Facebook when patients access web portals for some health-care providers.

Facebook’s Pixel tracking tool redirects patient communications and other supposedly “secure” information without authorization and in violation of federal and state laws, according to the lawsuit filed Friday in San Francisco federal court as a proposed class action on behalf of millions of patients.
