AI Legal Assistant · free · answers in seconds · general information, not legal advice
There are two Mount Sinai privacy settlements, and they are at opposite ends. The New York MyChart case (Cooper v. Mount Sinai Health System) already paid: payments went out on February 3, 2026, and uncashed checks became void after May 4, 2026. The Florida case (Boggiano v. Mount Sinai Medical Center of Florida) has no payment date — as of October 12, 2026 it is waiting for final approval. This page covers only the money; the case itself is on our Mount Sinai settlement overview.

Which Mount Sinai Settlement Is Yours?
Both cases are about tracking technology on hospital websites and patient portals, which is why they get mixed up. They involve different hospitals, different courts and different administrators.
New York (paid out): Mount Sinai Health System. The class is Mount Sinai MyChart account holders who logged in at mychart.mountsinai.org between October 27, 2020 and October 27, 2023 — about 1,314,147 people. Claims closed October 14, 2025.
Florida (not yet paid): Mount Sinai Medical Center of Florida. The class is everyone who accessed its website or patient portal between June 10, 2021 and September 18, 2025. Claims closed September 28, 2026.
Mount Sinai Health System denied that medical information was shared with Facebook; Mount Sinai Medical Center of Florida denies wrongdoing. Neither settlement is an admission. More on the claims themselves is on the overview page.
Case Details
New York: Cooper, et al. v. Mount Sinai Health System, Inc., Case No. 1:23-cv-09485-PAE, U.S. District Court for the Southern District of New York, Judge Paul A. Engelmayer. Administrator: Kroll Settlement Administration, (833) 890-5910, Mount Sinai Settlement c/o Kroll Settlement Administration LLC, P.O. Box 225391, New York, NY 10150-5391.
Florida: Boggiano, et al. v. Mount Sinai Medical Center of Florida, Case No. CACE-26-006904-09, Circuit Court of the 17th Judicial Circuit in and for Broward County, Judge Jeffrey R. Levenson. Administrator: Atticus Administration, 800-485-1017, mountsinaidatasettlement@atticusadmin.com, PO Box 64053, St. Paul, MN 55164. Official site: mountsinaidatasettlement.com.
Mount Sinai Settlement Payments: Where Each Case Stands
Florida — no payment date. As of October 12, 2026 no payment date has been announced. The last completed step was the claim deadline on September 28, 2026. The final approval hearing was set for October 13, 2026 at 9:30 a.m. before Judge Levenson.
The settlement agreement fixes the order of steps, not a calendar date:
1. The court must enter a Final Approval Order.
2. The Effective Date follows. If no objections were made, it is “the day after the entry of the Final Approval Order.” If there were objections, it is 30 days after the order, or later if there is an appeal. The final approval motion, filed August 28, 2026 (before the September 14 objection and opt-out deadline), reported no objections and nine opt-outs; we have not seen a later count.
3. Atticus must pay “no later than 30 days after the Effective Date or completion of the Settlement Administrator’s validity review, whichever is later.”
Who Gets Paid Automatically, Who Needed a Claim
New York: only people who filed a valid claim by October 14, 2025 were paid. There was no automatic payment. If you did not file, nothing is coming from this case.
Florida: cash goes only to people who filed a valid claim by September 28, 2026. Everyone in the class gets one year of Medical Data Monitoring without filing. The activation code is printed on your settlement notice, and it can be activated only after final approval.
If you are unsure whether your Florida claim was accepted, contact Atticus with your Claim ID or the unique ID from your notice.
Mount Sinai Settlement Amount: Paid vs. Estimated
Florida — estimate only. The notice estimates $20 per valid claim from a $220,000 cash pool. The amount moves up or down depending on how many valid claims there are, and an increase is capped at $250 per person. As of August 24, 2026, Atticus had received 4,311 claim submissions and judged 4,168 of them valid; the final count after the September 28 deadline has not been published. Fees and administration costs are paid separately by the hospital and do not reduce the cash pool. Money left after proration goes to a court-approved cy pres recipient.
How cases like this one end
Our copy of the federal courts’ own case database covers 118,291 other personal injury casesclosed in U.S. federal district courts between 2015 and 2026, 3.9% of them filed as class actions:
- 39.6% ended in a settlement recorded by the court. Another 14% were dismissed voluntarily, which often follows a private settlement — so the real settlement share sits between 39.6% and 53.6%.
- 5.7% were decided on a motion before any trial.
- 1 in 109 reached a trial (0.9%), after a median of 23.9 months.
- Median time from filing to the end of the case: 9 months.
- Only 802 of them (0.7%) record a money award at all; the median of those is $537,500.
These are base rates for this type of case (federal other personal injury cases) — not a prediction about this lawsuit, and not legal advice. Source: Federal Judicial Center, Integrated Database (civil), analysed by Settlement Insight. Cases heard in state courts are not included.

Three Things to Watch For
Mount Sinai payment searches have specific traps:
The old New York settlement website
mountsinaisettlement.com was the court-approved Kroll site for the New York case. As of October 12, 2026 that address shows an online casino page. Do not enter a Claim ID or personal details there. For the New York case, call Kroll at (833) 890-5910.
Payment emails from the wrong sender
In the New York case, real electronic payment notices came from notifications@zellepay.com, service@paypal.com, venmo@venmo.com, or mountsinaisettlement@hawkmarketplace.com for the virtual Mastercard. In the Florida case, administrator emails come from the atticusadmin.com domain. Anything else asking you to “confirm” banking details is suspect.
“Pay a fee to release your Florida payment”
The hospital pays the administration costs and attorneys’ fees separately. A real Florida payment never requires a fee, a tax prepayment or your Social Security number. Check with Atticus at 800-485-1017.
Mount Sinai Settlement Payments — Questions People Actually Ask
What is the Mount Sinai settlement payout date?
In the New York MyChart case, payments were issued on February 3, 2026. In the Florida case, as of October 12, 2026 no payment date has been announced. Atticus must pay within 30 days after the Effective Date or after it finishes reviewing claims, whichever is later.
What is the Mount Sinai settlement amount per person?
New York: a pro rata share of the $5,256,588 fund after fees and costs. Kroll did not publish a per-claim figure, so check your own payment notice. Florida: an estimated $20 per valid claim from $220,000, adjusted up or down, with any increase capped at $250.
How were the Mount Sinai settlement payments sent?
New York: paper claims got a paper check. Online claims were paid the way the claimant chose — Zelle, PayPal, Venmo, direct deposit or a virtual Mastercard. Florida: a check, unless you chose PayPal, Venmo or Zelle on your claim form.
When to expect a settlement payment in the Florida case?
Not before final approval. The hearing was set for October 13, 2026. If the court approves and no objections were filed, the Effective Date is the next day. Payment is due within 30 days after that, or after the claim review ends if that comes later. If anyone appeals, payment waits for the appeal.
How can I track my settlement check?
Florida: use mountsinaidatasettlement.com, call 800-485-1017 or email mountsinaidatasettlement@atticusadmin.com with your Claim ID. New York: call Kroll at (833) 890-5910. For electronic payments, contact the payment service: PayPal 1-888-221-1161, Venmo 1-855-812-4430, virtual Mastercard 1-844-340-1929. For Zelle or direct deposit, contact your bank.
I lost or never cashed my New York check. What now?
Checks became void after May 4, 2026. The settlement site did not describe a reissue process, so call Kroll at (833) 890-5910 and ask whether the payment can be reissued. We could not confirm whether leftover money will go to a second distribution or to a cy pres recipient.
Do I get anything from the Florida case without filing a claim?
Yes. All class members get one year of free Medical Data Monitoring, using the activation code on their notice. Cash goes only to people with a valid claim filed by September 28, 2026.
Which settlements are paying out now?
Of the two Mount Sinai cases, New York already paid and Florida has not started. For other cases, see our list of open class action settlements. “MyChart settlements” at other hospitals are separate cases with their own administrators and dates.
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.
