What the Lawsuit Alleges
Between August 1, 2018 and March 30, 2019, hackers accessed the systems of American Medical Collection Agency (AMCA), a third-party billing collector LabCorp used for patient debt collection. Exposed data included names, addresses, dates of birth, account balances, and payment card or banking details of roughly 10.25 million LabCorp patients — part of a broader AMCA compromise affecting more than 25 million people across several lab companies. The multidistrict litigation (In re: AMCA Customer Data Security Breach Litigation) alleged LabCorp failed to vet and monitor its vendor's data security. LabCorp denies wrongdoing but agreed to a $35 million settlement in 2026, seven years after the breach.
Case Details
U.S. District Court for the District of New Jersey — MDL Civil Action No. 19-md-2904. Settlement administered by Kroll (amcadatabreachsettlement83395.com).
Current Status
Who Is Affected & Can You Join?
You may qualify if LabCorp transmitted your personal information to Retrieval-Masters Creditor's Bureau d/b/a AMCA and your data was in AMCA's systems during the breach window (August 1, 2018 – March 30, 2019). In practice that means LabCorp patients whose unpaid balances were referred to AMCA for collection in that period. Class members were mailed notices with claim IDs, but you can also look up eligibility through the settlement administrator.

Scam & Misinformation Warnings
Whenever a brand lawsuit goes viral, scam sites and bad actors follow. Watch for these red flags:
Fake 'LabCorp settlement' phishing emails
The administrator communicates from the official Kroll settlement domain and never asks for your full Social Security number, bank login, or a fee to file. Emails demanding urgent 'verification' of banking credentials are phishing.
Paid claim-filing services
Filing is free at the official administrator site (amcadatabreachsettlement83395.com). Any site or caller charging a fee to 'file your LabCorp claim' is taking a cut of nothing — they have no special access.
Confusing this with the Quest Diagnostics AMCA settlement
Quest patients were part of the same AMCA breach but had a separate settlement with its own (now closed) claims process. A Quest notice does not make you a LabCorp class member, and vice versa.
Frequently Asked Questions
How much will I get from the LabCorp settlement?
If you claim documented out-of-pocket losses, up to $5,000 with proof. The no-documentation alternative cash payment is estimated at $50 but adjusts pro rata — if many people file, it shrinks; if few file, it can grow. California residents get an extra $50. Cash options can be combined with two years of medical-information monitoring.
When is the claim deadline?
September 3, 2026. The opt-out/objection deadline is earlier — July 27, 2026 — and the final approval hearing is August 20, 2026.
Am I eligible if I never got a letter?
Possibly. Eligibility turns on whether LabCorp sent your information to AMCA for collection between August 2018 and March 2019. If you had a LabCorp bill go to collections in that window, check the administrator site — you can submit a claim even without a mailed notice ID, subject to validation.
When will payments actually arrive?
After the August 20, 2026 final approval hearing, plus any appeal period. Realistically late 2026 at the earliest. No checks have been mailed as of July 2026.
What happened to AMCA itself?
The collection agency filed for bankruptcy in June 2019 under the cost of the breach — which is why the litigation pursued the lab companies that hired it. LabCorp's $35M settlement resolves the claims against LabCorp specifically.
Do I need a lawyer to file?
No. Filing a claim is free and takes minutes on the administrator site. Class counsel is already appointed and paid from the fund. A private attorney only makes sense if you suffered large, documented identity-theft losses and are considering opting out to sue individually — the opt-out deadline is July 27, 2026.
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.
