Kaiser Permanente, a major nonprofit health system operating in multiple states, agreed to a $47.5 million settlement after members alleged the company used common “web tracking” tools (such as pixels and analytics code) on its websites and mobile apps in ways that could transmit data about users’ activity on authenticated, logged-in pages. Plaintiffs say that when patients used online portals—where people schedule appointments, view benefits, or interact with care-related tools—the trackers enabled third parties to receive information linked to an individual’s health care interactions without clear permission. The settlement covers Kaiser members in California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia, Washington, and Washington, D.C. who accessed authenticated pages between November 2017 and May 2024, with estimated payments of roughly $20–$40 depending on claim volume and membership duration. The lawsuit was filed because health information is among the most sensitive categories of personal data, and patients typically expect that what they do inside a provider’s portal stays between them and the provider. The case alleges violations of federal and state privacy laws by sharing patient-related browsing and interaction data with third parties, even if Kaiser denies wrongdoing; settling allows Kaiser to resolve the claims without admitting liability while putting real money behind the privacy expectations patients have when using digital health tools. Beyond individual payments, the case is significant because it spotlights how marketing/analytics technology—routine in retail and media—can become legally and ethically fraught when embedded in health care environments where the consequences of disclosure are higher. More broadly, this fits a growing wave of litigation and regulatory scrutiny over tracking technologies in health care, where “HIPAA-covered entities” and their vendors must safeguard protected health information and limit disclosures without authorization. Plaintiffs’ theories in similar cases often overlap with HIPAA’s privacy framework (even though HIPAA itself generally doesn’t provide a private right of action), as well as state consumer privacy and medical confidentiality laws, and concerns about data flows to platforms like ad networks. The industry implication is clear: health systems, telehealth companies, and health apps are being pushed to audit pixels/SDKs, tighten vendor contracts and consent mechanisms, and redesign patient portals so analytics can’t inadvertently expose sensitive health-related interactions to third parties.
