Who Is Labcorp and Why Are They Being Sued for This Data Breach?

Labcorp runs one of the largest networks of diagnostic testing labs in the country, and like most large labs, it outsources unpaid patient balances to a collections agency. That agency was American Medical Collection Agency (AMCA). Handing a vendor your patients’ names, billing details, and health information is standard practice — but it only works if the vendor actually secures it. AMCA didn’t. The lawsuit claims Labcorp should have vetted AMCA’s security and limited what it shared, and instead handed over data for more than 10.2 million patients that ended up sitting on a system hackers accessed for seven straight months.

What Did Labcorp and AMCA Do to Patients Between August 2018 and March 2019?

Here’s the plain-English version: AMCA’s payment portal had a hole in it, and hackers walked through it undetected from roughly August 1, 2018 to March 30, 2019. The lawsuit alleges negligence — that Labcorp and AMCA failed to use reasonable data security measures — and breach of contract, since Labcorp’s agreement with AMCA presumably required it to keep patient data safe. Neither company has admitted wrongdoing. Both deny the claims outright.

This wasn’t an isolated incident, either. Labcorp is far from the only company that’s had to answer for a third-party vendor’s failures — this site has also covered the AT&T $177 million data breach settlement and the Thompson Coburn law firm data breach settlement, both built on the same core allegation: a company trusted with sensitive data didn’t protect it well enough.

What most coverage of this case leaves out: AMCA, the company that actually caused this mess, filed for Chapter 11 bankruptcy in June 2019 — weeks after the breach became public — and still has no finalized settlement of its own. Labcorp is one of roughly 21 companies whose client data passed through AMCA’s systems, and it’s the first of those companies to reach a deal. If you also used Quest Diagnostics or another AMCA client, watch for a separate notice — this settlement covers Labcorp patients only.

Who Qualifies for the Labcorp AMCA Data Breach Settlement?

Here’s exactly how to know if this case includes you.

• Anyone whose personal information Labcorp transmitted to AMCA, where that information sat inside AMCA’s compromised systems
• Patients who received a Labcorp billing statement or diagnostic service and later got a breach notice referencing AMCA
• Those excluded are limited to Labcorp officers and directors, the presiding judge, and anyone criminally convicted of causing the breach

Labcorp Patients Outside New Jersey — Are You Still Covered?

Yes. This is a nationwide settlement class, not limited to New Jersey residents. The case is being handled in the District of New Jersey because that’s where the multidistrict litigation was consolidated — but if Labcorp sent your data to AMCA, your state of residence doesn’t affect your eligibility.

How Much Can Labcorp AMCA Settlement Class Members Get? Up to $5,000 Per Person

You have two paths here, and they’re mutually exclusive — pick one.

Documented Out-of-Pocket Losses — Up to $5,000. If the breach actually cost you money, you can claim reimbursement for identity theft or fraud losses, credit monitoring you paid for, legal or credit-repair fees, and miscellaneous costs like notary or postage charges. You can also claim up to 10 hours of your own time spent fixing the mess, at $25 an hour. This tier requires real documentation — receipts, statements, something dated. Handwritten notes alone won’t cut it.

Alternative Cash Payment — Estimated $50, No Proof Needed. If you can’t point to a specific loss, you’re not shut out. You still get a payment, estimated at $50, just for filing.

Both tiers move on a pro-rata basis — more filers means smaller checks, fewer filers means bigger ones. Every eligible class member, regardless of which tier they pick, can also claim two years of CyEx Medical Shield Pro medical identity monitoring. Attorneys are asking for up to one-third of the $35 million fund, plus $5,000 service awards for each named plaintiff — standard for a case of this size, but worth knowing before you decide how much time to put into this. Payments over $600 may show up on a 1099. Talk to a tax professional if that applies to you.

How to File Your Labcorp AMCA Settlement Claim — Step by Step

1. Go to the official claim site: AMCADataBreachSettlement83395.com
2. Click “Submit a Claim” and choose your class member ID from the notice, or file without one if you didn’t receive a notice
3. Choose your payout tier: documented losses (up to $5,000) or the $50 alternative payment
4. Upload proof if you’re claiming documented losses — receipts, statements, or other dated records, not handwritten notes
5. Submit and save your confirmation number
6. Watch your email — Kroll Settlement Administration will reach out if anything else is needed

Takes about 5-10 minutes for the no-proof option. You have until September 3, 2026 — that’s roughly two months from today. Don’t let a notice you half-remember getting turn into money you never claimed.

Should Labcorp Class Members Opt Out or Object Before July 27, 2026?

What Opting Out of the Labcorp Settlement Actually Means

Opting out means you get no payment and no monitoring, but you keep the right to sue Labcorp separately over the same allegations, subject to Labcorp’s available defenses, including the statute of limitations. Most people should not opt out without talking to a lawyer first, since individual data breach lawsuits are expensive and slow compared to a settlement claim. The exact deadline to request exclusion is July 27, 2026.

How to Object to the Labcorp Settlement

Staying in the class doesn’t stop you from objecting. You can tell the court in writing why you disagree with the terms — including the attorneys’ fee request — by mailing a written objection to Kroll Settlement Administration LLC, PO Box 5324, New York, NY 10150-5324, postmarked no later than July 27, 2026. Your objection needs your full name, contact information, the case name and docket number (19-md-2904), your class member ID, and your signature.

Talk to a class action lawsuit attorney before July 27, 2026 if you’re considering either option.

Labcorp AMCA Data Breach Settlement — Frequently Asked Questions, No. 19-md-2904

Do I need a lawyer to file a Labcorp AMCA settlement claim?

 No. The claim form on AMCADataBreachSettlement83395.com takes a few minutes for the no-proof option. A lawyer is worth consulting only if you’re weighing whether to opt out or if your documented losses are unusually large.

Is the Labcorp AMCA data breach settlement legitimate?

 Yes. It’s tied to a real federal case, In re AMCA Customer Data Security Breach Litigation, No. 19-md-2904, administered by Kroll Settlement Administration on a court-authorized site. A legitimate settlement never charges you a fee to file.

When will Labcorp settlement payments be sent? 

Not before the August 20, 2026 final approval hearing, and only after any appeals of that approval are resolved. There’s no published payment date yet.

What if I missed the Labcorp claim deadline? 

Once September 3, 2026 passes without a filed claim, you generally lose the right to a payment or monitoring service, even though you remain bound by the settlement’s terms as a class member.

Will my Labcorp settlement payment go on a 1099? 

Possibly, if your payment exceeds $600. Speak with a tax professional about how a settlement payment affects your return.

Is Quest Diagnostics part of this same settlement?

 No. Quest Diagnostics, BioReference Laboratories, and other AMCA client companies are separate defendants in the broader litigation. This settlement resolves claims against Labcorp only. Watch for separate notices if you used one of those other providers.

Do I have to prove Labcorp sent my data to AMCA? 

No. The settlement administrator determines eligibility. If you’re unsure, file anyway — you’ll be notified if you don’t qualify.
