Who qualifies for the Labcorp AMCA data breach settlement?

You qualify if you are an individual for whom Laboratory Corporation of America Holdings (Labcorp) transmitted personal information to American Medical Collection Agency (AMCA), and that information was contained in the computer systems implicated by the AMCA cybersecurity incident that occurred between approximately August 2018 and March 2019. Most class members received a notice with a Class Member ID by email or mail. Excluded from the class are Labcorp's officers and directors, the judge and magistrate assigned to the case, and anyone found criminally responsible for the breach.

How much can I get from the Labcorp AMCA settlement?

There are two cash options, and you may choose only one. (1) Alternative Cash Payment: an estimated $50 per valid claimant, with no documentation required beyond your Class Member ID. The amount may go up or down pro rata depending on how many claims are filed. (2) Out-of-Pocket Losses: reimbursement of up to $5,000 for documented, unreimbursed costs fairly traceable to the breach, including identity-theft losses, professional service costs, miscellaneous expenses, credit-monitoring costs incurred on or after August 1, 2018, and up to 10 hours of lost time at $25 per hour. In addition to one of the cash options, every class member may also elect two years of free CyEx Medical Shield Pro medical and healthcare information monitoring.

Do I need proof to file a Labcorp AMCA data breach claim?

To file, you need the Class Member ID printed on the email or mailed notice you received about the settlement. If you cannot locate your Class Member ID, you can request help through the official settlement website. The Alternative Cash Payment (estimated $50) and the two years of medical monitoring require no additional documentation. The up-to-$5,000 Out-of-Pocket Losses option does require documentation — receipts, bank statements, or other records showing the cost and connecting it to the breach, plus a signed attestation. Self-prepared documents such as handwritten receipts are not sufficient on their own.

What is the deadline to file a Labcorp AMCA settlement claim?

The claim deadline is September 3, 2026. Online claim forms must be submitted, and mailed claim forms must be postmarked, by that date. The deadline to opt out of or object to the settlement is earlier, on July 27, 2026. The Final Fairness Hearing is scheduled for August 20, 2026 at 11:00 a.m. before U.S. District Judge Michael A. Hammer in Newark, New Jersey.

Labcorp AMCA Data Breach Settlement

Q: What was the AMCA data breach?

American Medical Collection Agency (AMCA), a third-party billing collections vendor used by Labcorp and other companies, reported a cybersecurity incident affecting its computer systems between approximately August 1, 2018 and March 30, 2019. During that window, an unauthorized party had access to AMCA systems that contained personal information Labcorp had transmitted to AMCA. The case is In re: American Medical Collection Agency, Inc.

Labcorp denies all claims and the settlement is not an admission of wrongdoing.

What Is the Labcorp AMCA Data Breach Class Action Settlement?

Did you receive diagnostic or lab services from Laboratory Corporation of America Holdings (Labcorp), or a notice telling you your information was caught up in the AMCA data breach? A $35,000,000 settlement has been reached, and you may be eligible for an Alternative Cash Payment estimated at $50, or reimbursement of up to $5,000 for documented out-of-pocket losses, plus two years of free medical and healthcare information monitoring. The deadline to file a claim is September 3, 2026.

The lawsuit, captioned In re: American Medical Collection Agency, Inc. Customer Data Security Breach Litigation (All Actions Against Laboratory Corporation of America Holdings), Case No. 19-md-2904, is pending in the United States District Court for the District of New Jersey. It concerns a cybersecurity incident reported by American Medical Collection Agency (AMCA) — a third-party billing and collections vendor — that affected AMCA's computer systems between approximately August 1, 2018 and March 30, 2019. During that period, an unauthorized party had access to AMCA systems that contained personal information Labcorp had transmitted to AMCA, which may have included personally identifiable information and protected health information.

Labcorp denies all of the claims alleged against it and denies any wrongdoing or liability. The settlement is not an admission of wrongdoing, but rather a resolution of disputed claims that lets affected individuals receive benefits without the cost and risk of a trial.

Who Qualifies for the Labcorp AMCA Settlement?

The Settlement Class is defined as all individuals for whom Labcorp transmitted personal information to Retrieval-Masters Creditor's Bureau, Inc., doing business as American Medical Collection Agency (AMCA), where that information was contained in the computer systems implicated by the cybersecurity incident at AMCA that occurred between approximately August 2018 and March 2019.

Most class members were sent a notice with a unique Class Member ID by email or U.S. mail. If you received that notice, you are very likely a Settlement Class Member. If you are unsure whether you are included, you can ask for free help through the official settlement website.

The following are excluded from the Settlement Class: Labcorp and its officers and directors; the judge and magistrate assigned to evaluate the fairness of the settlement; and any person found by a court to be criminally responsible for initiating, causing, aiding, or abetting the security incident.

How Much Can You Get From the Labcorp AMCA Settlement?

The settlement creates a $35,000,000 Settlement Fund. After notice and administration costs, taxes, service awards, and attorneys' fees and expenses are paid, the remaining money funds the class benefits. You may choose one of two cash options, and you may also elect free monitoring in addition to your cash choice.

Option 1: Alternative Cash Payment (estimated $50, no documentation required). In lieu of seeking out-of-pocket losses, you can claim a flat Alternative Cash Payment estimated at $50 per valid claimant. No receipts or documentation are required beyond your Class Member ID. The exact amount may be higher or lower than $50 because it is distributed pro rata — the net settlement fund is divided evenly among everyone who files a valid Alternative Cash Payment claim, so the per-person figure depends on how many people file.

Option 2: Out-of-Pocket Losses (up to $5,000, documentation required). If you incurred unreimbursed costs fairly traceable to the AMCA security incident, you can instead claim reimbursement of up to $5,000 total per person. Reimbursable costs include:

• Unreimbursed costs, expenses, losses, or charges from identity theft, identity fraud, medical fraud, or other misuse of your personal information
• Professional service costs — such as law firms or credit-repair services — related to misuse of your personal information
• Miscellaneous expenses such as notary, fax, postage, copying, mileage, and long-distance phone charges
• Credit-monitoring costs incurred on or after August 1, 2018 through the claim deadline
• Up to 10 hours of documented time spent remedying fraud or misuse, valued at $25 per hour (up to $250)

Out-of-Pocket Losses claims are also subject to pro rata increases or decreases depending on the number of claims filed. These claims require documentation plus a signed attestation that the losses are fairly traceable to the security incident and were not caused by some other event.

Plus: Two years of medical monitoring (no documentation required). In addition to one of the cash options above, every Settlement Class Member may also claim and enroll in up to two years of CyEx Medical Shield Pro — a medical and healthcare information monitoring service. Because the AMCA breach involved health and billing data, this monitoring is a genuinely useful benefit worth electing even if you also take a cash payment.

$50 Cash vs. Up to $5,000 Documented — Which Should You Pick?

You can pick only one of the two cash options, so the choice comes down to whether you have documented losses traceable to the breach.

• No specific losses to document? The Alternative Cash Payment (estimated $50) is the practical path. It requires only your Class Member ID and a few minutes — no receipts, no bank statements. Add the two years of medical monitoring on top.
• Did you spend money or lose time because of fraud or misuse? The Out-of-Pocket Losses option can recover up to $5,000, which is far more than the flat cash payment. It is worth the documentation effort if you have receipts, bank statements, or other records connecting the cost to the AMCA breach, plus time spent remedying the problem.

How to File a Labcorp AMCA Data Breach Claim

Two methods are available, both with the same September 3, 2026 deadline.

Method 1: Online (fastest). Visit the official Settlement Website at amcadatabreachsettlement.com and submit the online Claim Form using the Class Member ID printed on the email or mailed notice you received. If you cannot locate your Class Member ID, use the contact option on the official settlement website to request it. On the form, select your cash option (the Alternative Cash Payment or Out-of-Pocket Losses) and indicate whether you want the two years of medical monitoring. For Out-of-Pocket Losses, upload your supporting documentation.

Method 2: U.S. mail. Download the printable Claim Form from the Settlement Website (or request a paper form from the Settlement Administrator), complete it, attach any supporting documentation for Out-of-Pocket Losses, and mail it to the Settlement Administrator. Mailed claims must be postmarked no later than September 3, 2026.

For Out-of-Pocket Losses claims: Gather receipts, bank or credit card statements, invoices, credit-monitoring bills, and any other records showing the amount spent or lost and connecting it to the AMCA security incident. Self-prepared documents such as handwritten receipts are not sufficient by themselves, but can be submitted to add support to other documentation. You must also sign the attestation confirming the losses are fairly traceable to the incident.

Key Labcorp AMCA Settlement Deadlines

• Submit a claim by: September 3, 2026 (online) or postmarked by September 3, 2026 (mail)
• Opt out of the settlement by: July 27, 2026
• Object to the settlement by: July 27, 2026
• Final Fairness Hearing: August 20, 2026 at 11:00 a.m., before U.S. District Judge Michael A. Hammer at the Martin Luther King Federal Courthouse in Newark, New Jersey (Courtroom 2C)

The date and time of the Final Fairness Hearing may change without further notice, so check the official settlement website for updates.

When Will I Receive My Labcorp AMCA Settlement Payment?

Payments will be distributed only after the Court grants final approval at the August 20, 2026 fairness hearing and after any appeals are resolved or the period to appeal has expired. The settlement notice does not specify an exact distribution date.

• If no appeals are filed: distribution would likely begin some months after final approval, once the claim period closes and the appeal window passes.
• If appeals are filed: distribution can be delayed by a year or more while the appellate court reviews the settlement, the fee award, or the allocation method.

What Happens If I Do Nothing?

If you do nothing and are a Settlement Class Member, you remain in the class but will not receive any cash payment or monitoring. Unless you opt out, you will also give up your right to sue Labcorp over the legal claims released by the settlement, including claims arising out of or related to the AMCA security incident. Because the Alternative Cash Payment requires no documentation and the medical monitoring is free, filing a claim is the practical choice for most class members and takes only a few minutes.

How to Opt Out or Object to the Settlement

Class members who do not want to be bound by the settlement have two alternatives, both with the same July 27, 2026 deadline.

Opting out means giving up all settlement benefits but keeping the right to sue Labcorp individually over the same claims (subject to any defenses Labcorp may have, including statutes of limitations). A request for exclusion must be in writing, postmarked by July 27, 2026, and mailed to the Settlement Administrator. It must include the name of the proceeding and case number, your full name, your current mailing address and telephone number, your personal signature, and a clear statement that you want to be excluded ("Request for Exclusion").

Objecting means staying in the class (and remaining eligible for benefits) but asking the Court to reject or change the settlement. A valid objection must include your contact information, the case name and docket number, information identifying you as a Settlement Class Member (such as your Class Member ID), a written statement of the grounds for your objection, the identity of any counsel representing you, a list of any other class action cases in which you or your counsel have objected, whether you intend to appear at the Final Fairness Hearing, and your personal signature. Objections must be postmarked to the Settlement Administrator no later than July 27, 2026. You can both object and still submit a Claim Form to receive a payment.
