About the Mount Sinai Settlement

Mount Sinai Health System agreed to pay $5,256,588 to resolve patient privacy violation claims after allegations surfaced about sharing personal health information with Facebook through Meta Pixel tracking technology. 

 

This healthcare data breach settlement addresses serious concerns about patient data protection and healthcare portal privacy. 

 

The lawyers handling this lawsuit say the case highlights increasing worries about how healthcare providers share medical records and use tracking technology on their patient websites. According to the attorneys, this settlement reflects broader concerns about privacy protections in digital healthcare platforms.

 

Mount Sinai Data Breach Allegations Explained

Several lawsuits have accused the healthcare provider of illegally sharing patient data with Facebook. 

 

Plaintiffs say that from October 27, 2020, to October 27, 2023, Mount Sinai's healthcare system used Facebook’s Pixel and Conversions API (CAPI) on its MyChart patient portal allegedly without obtaining proper patient consent.

 

This tracking technology allegedly violated federal and state privacy laws by collecting and transmitting sensitive health information to third parties. 

 

Attorneys for the plaintiffs also argued that privacy violations went far beyond typical website analytics, as the tracking captured data from critical healthcare activities, including when patients:

  • Viewed test results
  • Scheduled appointments
  • Communicated with doctors
  • Accessed medical records
  • Reviewed billing information

 

Mount Sinai's response

Mount Sinai Health System denied all allegations in the lawsuit, emphasizing that “no medical information from the patient portal was shared with Facebook.”

 

Despite these denials, the healthcare giant settled the case rather than face the expenses and unpredictable outcomes of extended court proceedings.

 

The settlement allows Mount Sinai to resolve the privacy dispute while maintaining its position of innocence. Under the agreement, the health system will compensate affected patients without admitting wrongdoing or accepting legal liability for the alleged privacy violations.

 

More on Facebook Pixel CAPI Tech 

The alleged Facebook pixel and CAPI interface work primarily by embedding tracking code into websites.

 

When patients logged into their MyChart patient portal, this technology allegedly captured information about their online activities.

 

The lawsuit claims this tracking violated multiple laws including:

  • Federal Electronic Communications Privacy Act
  • New York Deceptive Trade Practices laws
  • HIPAA regulations regarding protected health information

 

Class action attorneys argued that these tracking technologies captured detailed user behavior, including page visits, click patterns, and time spent on specific portal sections.

 

The invasion of privacy claims stem from the alleged unauthorized sharing of these behavioral patterns with Facebook, even if specific medical details weren't directly transmitted.

 

Lawsuit Proceedings and Progress

The Mount Sinai lawsuit settlement originated when four plaintiffs—Ronda Cooper, Coral Fraser, David Giltin, and Gilbert Manda—filed suit in the United States District Court for the Southern District of New York. 

 

The case progressed through initial motions and discovery before the parties agreed to mediation, which led to the current settlement agreement that received preliminary approval on June 16, 2025.

 

Legal claims

The plaintiffs alleged multiple violations:

  • Electronic Communications Privacy Act violations: Unauthorized interception of electronic communications.
  • New York Deceptive Trade Practices: Misrepresentation of data collection practices.
  • Breach of fiduciary duty: Violation of patient-provider trust.
  • Unjust enrichment: Benefiting from unauthorized data collection.
  • Breach of implied contract: Violating privacy policy terms.
  • Invasion of privacy: Intrusion upon seclusion.

 

These claims reflected growing concerns about healthcare data privacy in the digital age.

Frequently Asked Questions (FAQ)

You're eligible if you had a Mount Sinai MyChart account and logged into it through MyChart.mountsinai.org between October 27, 2020, and October 27, 2023. The settlement administrator has identified approximately 1,314,147 eligible class members who should have received or will receive a notice with a unique ID number that confirms their eligibility status.

 

If you miss the October 14, 2025 deadline, you forfeit your right to receive any payment from the $5,256,588 settlement fund. You'll still be bound by the settlement terms, meaning you can't sue Mount Sinai individually for these privacy violations, but you won't receive any compensation for the alleged unauthorized data sharing with Facebook.

 

No, opting out means you exclude yourself entirely from the settlement class and forfeit any payment. However, opting out preserves your right to file an individual lawsuit against Mount Sinai for the same privacy violations, though you'd need to pursue that separately with your attorney.

 

While Mount Sinai denies sharing medical records, the lawsuit alleges that Meta Pixel tracking captured login patterns, pages visited, types of medical information accessed, appointment scheduling activities, and communication patterns within the MyChart portal. The specific medical details weren't necessarily shared, but behavioral data about how patients used the healthcare portal allegedly was transmitted to Facebook.
