What Happened?

Between March 18 and March 24, 2024, ALN Medical Management—Hoag Clinic’s revenue-cycle and billing vendor—detected unusual activity in a third-party hosting environment. An investigation confirmed that an unauthorized actor accessed and exfiltrated files containing patient information. ALN isolated the affected systems immediately, engaged cybersecurity experts, and completed a comprehensive review by January 31, 2025.

What Information Was Exposed?

The compromised files held a mix of Personally Identifiable Information (PII) and Protected Health Information (PHI), including:

• Full names & mother’s maiden names
• Dates of birth & addresses
• Social Security numbers and taxpayer identification numbers
• Driver’s license and other government ID numbers
• Health insurance and detailed medical information
• Financial account and payment card details

Who Is Affected?

Hoag Clinic patients whose data was processed by ALN during the breach window are at risk. At least 258 Massachusetts residents have been notified so far, with notices continuing nationwide.

Hoag Clinic & ALN’s Response

• Notification letters began mailing on March 21, 2025.
• ALN is providing 24 months of complimentary credit monitoring and identity-theft protection via IDX. Enrollment deadline: June 21, 2025.
• A dedicated assistance line—1-877-720-6166—is open Monday–Friday, 9 a.m.–9 p.m. ET (excluding holidays).

Steps You Should Take Now

1. Enroll in IDX services using the link above to catch fraudulent activity early.
2. Pull free credit reports at least quarterly from AnnualCreditReport.com.
3. Place a fraud alert or credit freeze with Equifax, Experian, and TransUnion to block new credit lines in your name.
4. Monitor medical statements for unfamiliar services or charges.
5. Record and report any suspicious activity to your financial institutions and local law enforcement.

Can You File a Lawsuit?

If your information was involved, you may be entitled to monetary relief for out-of-pocket losses, time spent addressing fraud, and future credit-monitoring costs. Class-action investigations are underway to hold Hoag Clinic and ALN accountable for failing to safeguard patient data.

Eligibility typically hinges on receiving an official breach notice letter. Even if you have not yet seen fraudulent charges, courts increasingly recognize the inherent risk tied to stolen medical and financial data.

How to Preserve Your Rights

• Save all breach-related correspondence.
• Document any identity-theft expenses or time spent remediation.
• Consult with a data-breach attorney before opting out of any class-action settlement.

Frequently Asked Questions

What makes the Hoag Clinic data breach different?

Unlike many healthcare incidents, this breach exposed not only PHI but also financial details and Social Security numbers, significantly heightening identity-theft risks.

How do I know if I was included in the Hoag Clinic breach?

Hoag Clinic and ALN are mailing letters to impacted patients. If you received one—or if you were treated at Hoag between 2019 and 2024—you should assume your data may have been involved and take precautionary steps.

Is the free credit monitoring enough?

While helpful, credit monitoring only alerts you after suspicious activity occurs. Adding a credit freeze and ongoing statement reviews provides stronger protection.

Will joining a Hoag Clinic data breach lawsuit affect my medical care?

No. Lawsuits target the entities responsible for data security lapses, not your healthcare services or providers. Your treatment will remain unchanged.

How long do I have to take legal action?

Limitations periods vary by state—often 1–3 years from discovery of the breach. Acting promptly preserves evidence and maximizes potential compensation.
