AI Legal Assistant · free · answers in seconds · general information, not legal advice
There are two separate federal cases against Allegheny Health Network (AHN), both in Pittsburgh. One, filed in 2023, alleges the ahn.org website passed patients’ health information to Meta and Google. The other is the Allegheny Health Network data breach case over a 2024 hack at IT vendor IntraSystems that exposed about 294,000 home care patients. On August 5, 2026 a judge let most of the breach claims go forward. As of October 6, 2026 neither case has a settlement, a fund or a claim form.

What the Two Lawsuits Allege
The tracking case. In W.W. v. Allegheny Health Network, the plaintiff alleges that AHN collected confidential health information from people who visited the AHN website and disclosed it to third parties — Meta and Google, per Bloomberg Law — in violation of the federal wiretap law, 18 U.S.C. § 2511(1), and several Pennsylvania laws. These are allegations; AHN has not been found liable. The court opinions we read refer to the AHN website. We could not confirm that the complaint targets the MyChart portal itself.
The data breach case. AHN’s IT vendor IntraSystems LLC hosted systems for AHN’s Home Medical Equipment and Home Infusion companies. Hackers first got into systems holding patient data on October 11, 2024. IntraSystems told AHN on November 19, 2024. About 293,900 home care patients were affected, according to the HIPAA Journal. The files included names, addresses, dates of birth, Social Security numbers, financial account numbers, health insurance information and treatment details such as diagnoses, prescriptions and medical device serial numbers. The plaintiffs allege negligence, breach of fiduciary duty, breach of implied contract and unjust enrichment.
Case Details
Both cases are in the U.S. District Court for the Western District of Pennsylvania.
Tracking: W.W. v. Allegheny Health Network, No. 2:23-cv-01163, before Judge Christy Criswell Wiegand. The court lists it as a wiretapping case (18:2511). On February 27, 2025 she refused to send it to arbitration. AHN has posted its arbitration terms on its website only since December 19, 2022. The court found those terms were not displayed conspicuously and that AHN had not shown the plaintiff actually knew about them. Docket summaries indicate AHN then appealed to the Third Circuit and the district case was paused. We could not open the appeal docket to confirm where it stands.
Data breach: Dimoff v. Allegheny Health Network, No. 2:25-cv-00125, before Judge J. Nicholas Ranjan. The breach suits were consolidated there on March 3, 2025. A separate suit was also filed in Massachusetts federal court (No. 1:25-cv-10364). It names AHN’s home equipment and home infusion subsidiaries and IntraSystems. Court records: tracking-case opinion on GovInfo.
Status: Both Cases Pending, No Settlement
Breach case: On August 5, 2026, Judge Ranjan granted in part and denied in part the motions to dismiss. Claims of negligence, breach of fiduciary duty, breach of implied contract, unjust enrichment and declaratory judgment go forward against AHN. Claims of negligence and declaratory judgment go forward against IntraSystems. Law360 reported the ruling on August 6, 2026. No class has been certified.
Tracking case: It is still in court, not in arbitration, after the February 27, 2025 ruling. We could not confirm the outcome of AHN’s appeal. No class has been certified.

Who Could Be Covered
Breach case. No class definition has been approved by the court. The people most likely affected are home care patients of AHN Home Medical Equipment and Home Infusion whose data sat on the IntraSystems-managed systems. Notice letters were mailed by IntraSystems, starting in January 2025, with an offer of credit monitoring. If you got that letter, keep it — it is your best proof. Ordinary hospital or MyChart use alone does not put you in this group.
Tracking case. The plaintiff alleges AHN collected information from people who visited the AHN website, so website visitors are who the claims concern; no class has been defined by the court. If a class is ever certified or a settlement reached, a court-appointed administrator sends notice; you do not sign up now.
Our form on this page asks whether you used the AHN website or AHN MyChart, what you did there (booked an appointment, searched a condition, paid a bill) and when you last did it. Those are the facts a future class definition would turn on.
Is There Any Money?
For context only, not a prediction: other hospital tracking cases have ended both ways. Loyola Medicine settled for $2.67 million and received final approval on September 17, 2025 (details). A Hennepin Healthcare tracking suit was voluntarily dismissed with no payment (details). The open and closed hospital settlements are listed on our MyChart claim form page, and you can run numbers with the MyChart settlement calculator or the data breach settlement calculator.
How cases like this one end
Our copy of the federal courts’ own case database covers 80,165 other statutory actions casesclosed in U.S. federal district courts between 2015 and 2025, 11.8% of them filed as class actions:
- 26% ended in a settlement recorded by the court. Another 22.4% were dismissed voluntarily, which often follows a private settlement — so the real settlement share sits between 26% and 48.4%.
- 7.4% were decided on a motion before any trial.
- 1 in 155 reached a trial (0.6%), after a median of 22 months.
- Median time from filing to the end of the case: 5 months.
- Only 1,717 of them (2.1%) record a money award at all; the median of those is $195,000.
These are base rates for this type of case (federal other statutory actions 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
Two pending cases with no claim form are an easy story for imposters:
“Claim your AHN MyChart settlement”
No Allegheny Health Network tracking settlement exists as of October 2026. A page asking for your MyChart login or Social Security number to “file” is collecting data, not filing anything.
Fake IntraSystems or AHN breach calls
The real breach letters came by mail from IntraSystems and offered credit monitoring. A caller or text asking you to “verify” your bank account or pay a fee to get breach money is not from the court.
Other hospitals’ settlements pitched to AHN patients
Several hospital systems with similar-sounding names have their own tracking settlements. A settlement for another hospital does not cover AHN patients — check that the defendant on the official notice is Allegheny Health Network before you submit anything.
Allegheny Health Network Lawsuit — Questions People Ask
Is there an Allegheny Health Network MyChart lawsuit?
There is a tracking lawsuit, W.W. v. Allegheny Health Network (No. 2:23-cv-01163, W.D. Pa.), alleging the AHN website shared health information with Meta and Google. The opinions we read describe the website; we could not confirm that MyChart itself is part of the claims. As of October 6, 2026 there is no settlement.
What is AHN’s patient portal called?
MyChart. AHN’s site calls it the “AHN Patient Portal,” and patients log in through MyChart on the web or the MyChart app.
What happened in the Allegheny Health Network data breach?
Hackers got into systems run by AHN’s IT vendor IntraSystems starting October 11, 2024. The systems served AHN Home Medical Equipment and Home Infusion. About 294,000 patients were notified starting January 2025.
Is there a settlement or claim form?
No. As of October 6, 2026 neither case has a settlement, fund, administrator, claim form or deadline. If that changes, class members get notice from a court-appointed administrator.
What did the judge decide in August 2026?
On August 5, 2026 Judge Ranjan let claims of negligence, breach of fiduciary duty, breach of implied contract, unjust enrichment and declaratory judgment proceed against AHN, and negligence and declaratory judgment against IntraSystems. Some claims were dismissed. That is not a finding that AHN did anything wrong.
Why did AHN try to force the tracking case into arbitration?
AHN pointed to an arbitration clause in its website terms of service. On February 27, 2025 the court held the terms were not conspicuous enough to bind the plaintiff. Docket summaries indicate AHN appealed; we could not confirm the result.
Was there an earlier AHN data breach?
Yes. In 2022 AHN reported a phishing attack that compromised an employee email account between May 31 and June 1, 2022, potentially exposing data of approximately 8,000 patients. We found no class action or settlement tied to that incident.
What should I do now?
Keep any IntraSystems or AHN notice letter. Freeze your credit at the three bureaus if your Social Security number was listed. Check insurance statements for care you never received. If you used the AHN website or MyChart, note roughly when and for what — our form asks exactly that.
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.
