Mount Sinai Medical Center Settlement: Portal Users' Claim Deadline Was September 28
This one is broader than most people realize: you did not need to be hacked, and you did not need a breach notice. If you accessed Mount Sinai Medical Center of Florida's website or patient portal between June 2021 and September 2025, you are in the class. As of 24 August 2026, claims are open.

What the Case Is About
The class action alleged that Mount Sinai Medical Center of Florida embedded tracking, analytics and advertising technologies in its website and patient portal that disclosed visitors' personally identifiable information and protected health information to third parties — without consent. The complaint claimed violations of the Florida Security of Communications Act, invasion of privacy and unjust enrichment. This is not a hacking case: the data left through tools the hospital itself installed, which is exactly why the class is defined by portal use rather than by a breach notification list. Mount Sinai denies all allegations and settled for $220,000 to avoid the cost and risk of trial.
Case Details
The settlement covers people who accessed Mount Sinai Medical Center of Florida's website or patient portal between June 10, 2021 and September 18, 2025. A final approval hearing is scheduled for October 13, 2026. One distinction matters: this is the Florida Mount Sinai Medical Center settlement — it is separate from the $5.3 million Mount Sinai Health System (New York) web-tracking settlement you may also have read about. Different defendant, different fund, different claims process.
Status as of 24 August 2026
Who Can File
Anyone who accessed Mount Sinai Medical Center of Florida's website or patient portal between June 10, 2021 and September 18, 2025. That is a four-year window and includes routine visits — checking test results, booking an appointment, paying a bill, even browsing the site. You do not need a breach notice, because there was no breach notification list: the case is about tracking tools, and the class is anyone the tools could have touched. If you were a Mount Sinai Florida patient in those years, it is very likely you qualify.
What the Settlement Pays — Honestly
How This Case Got Here
- 1
June 10, 2021 — class window opens
The start of the period during which website and portal visits place a person in the settlement class.
- 2
Litigation over tracking tools
A class action alleges Mount Sinai Medical Center of Florida's tracking, analytics and advertising technologies disclosed patient data to third parties, violating the Florida Security of Communications Act.
- 3
September 18, 2025 — class window closes
The end of the eligibility period. The settlement covers website and portal use between the two dates.
- 4
September 28, 2026 — claim deadline (passed)
Claims must be submitted by this date, online at MountSinaiDataSettlement.com or by mail.
- 5
October 13, 2026 — final approval hearing
The court decides whether to approve the settlement. Payments follow final approval and any appeals.
Three Things to Keep Straight
Tracking-tool settlements confuse people because there was no “breach” — impostors exploit that confusion.
“You need your breach notice to file”
There is no breach notice in this case. Eligibility is based on having used the website or portal in the class period. Anyone demanding a notification letter — or charging to “look you up” — is not the administrator.
Confusing the two Mount Sinai settlements
The Florida settlement ($220,000, claims closed September 28, 2026) and the New York Mount Sinai Health System settlement ($5.3 million) are separate cases. Filing in one does not enroll you in the other, and a site blurring the two is at best sloppy.
A fee to claim or “release” your payment
Filing is free at MountSinaiDataSettlement.com. No administrator ever charges to process a claim or release a settlement payment; any such request is fraud.
Common Questions
When is the deadline?
The claim deadline was September 28, 2026 and has passed. The final approval hearing follows on October 13, 2026.
How much will I get?
An estimated $20, paid pro rata — the final amount depends on the number of valid claims against the $220,000 fund. All class members also qualify for one year of free medical data monitoring regardless of the cash amount.
Do I need proof that my data was shared?
No. The class is defined by use of the website or patient portal between June 10, 2021 and September 18, 2025 — not by proof of individual data disclosure. That is typical for tracking-technology settlements.
Is this the same as the $5.3 million Mount Sinai settlement?
No. That settlement involves Mount Sinai Health System in New York, also over web tracking. This page covers Mount Sinai Medical Center of Florida's $220,000 settlement. They are separate defendants with separate claims processes.
Was my medical data actually stolen?
This case does not involve theft by hackers. The allegation is that tracking and advertising tools on the hospital's own website transmitted visitor data — including health-related information — to third parties such as analytics and ad platforms. Mount Sinai denies the allegations; the settlement resolves the dispute without a finding either way.
When would the money arrive?
After the October 13, 2026 final approval hearing and the resolution of any appeals — realistically 2027. Approval authorizes payment; it does not itself move money.
How do I verify this?
The official settlement website is MountSinaiDataSettlement.com (with a toll-free administrator line listed there). Everything on this page reflects what we could confirm as of 24 August 2026; the official notice controls where anything differs.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
