MedicareCompareUSA Data Breach Lawsuit Investigation
Got a letter saying your Medicare or Social Security details were hacked? The MedicareCompareUSA email breach on behalf of United Healthcare has put thousands at risk. Find out how to protect yourself—and whether you can claim compensation—below.
What Happened?
Between November 5 and November 21, 2024, cyber-criminals gained unauthorized access to several internal email accounts used by MedicareCompareUSA. Those accounts contained files and messages with sensitive customer data belonging to people who enrolled in United Healthcare plans through MedicareCompareUSA.
After discovering “suspicious activity,” the company launched an investigation and informed United Healthcare on March 18, 2025. Formal breach notices began mailing to consumers on June 27, 2025, and regulatory filings were submitted the same day to the attorneys general of Massachusetts and Washington.
What Information Was Exposed?
The compromised accounts contained both personally identifiable information (PII) and protected health information (PHI), including:
- Full name
- Social Security number
- Date of birth
- Physical address
- Government-issued ID numbers
- Medicare and/or Medicaid numbers
- Health-insurance policy numbers
- Medical and financial details
Who Is Affected?
While the full headcount has not been publicly disclosed, filings confirm at least 1,258 Washington residents and one Massachusetts resident were impacted. Anyone who enrolled in a United Healthcare plan through MedicareCompareUSA during or before November 2024 should assume their data could be involved until confirmed otherwise.
Company Response & Free Services
To comply with federal and state law, MedicareCompareUSA is:
• Notifying affected consumers by certified mail.
• Offering 12 months of TransUnion Cyberscout single-bureau credit monitoring and identity-restoration support.
Your Next Steps
- Activate the free credit monitoring code provided in your notice.
- Review your credit reports for new accounts or inquiries you don’t recognize.
- Place a fraud alert or credit freeze with Experian, Equifax, or TransUnion to block unauthorized credit pulls.
- Watch for phishing attempts—scammers may reference United Healthcare or Medicare benefits to extract more data.
- Document any out-of-pocket losses (bank fees, time spent, or emotional distress) to support a potential legal claim.
Your Legal Rights
Under state privacy and consumer-protection laws, companies that mishandle sensitive data can be held liable for resulting damages. Victims of the MedicareCompareUSA breach may seek:
- Reimbursement for fraud-related expenses
- Compensation for time spent mitigating identity theft
- Relief for anxiety, emotional distress, or loss of privacy
Class-action investigations are underway to determine whether MedicareCompareUSA and/or United Healthcare used reasonable cybersecurity safeguards. If certified, eligible consumers could receive monetary compensation without paying out-of-pocket legal fees.

Frequently Asked Questions
What makes the MedicareCompareUSA data breach different?
This incident involves both PII and PHI—data categories protected under HIPAA and state privacy statutes—raising the stakes for potential misuse.
How do I know if I’m affected by the MedicareCompareUSA breach?
You should have received a mailed notice dated on or after June 27, 2025. If you enrolled in a United Healthcare Medicare plan via MedicareCompareUSA and haven’t received a letter, contact the company directly or monitor your credit for unexplained activity.
Is the free TransUnion Cyberscout monitoring enough?
Credit monitoring is a critical first step but not fool-proof. Consider adding fraud alerts, credit freezes, and monitoring medical insurance statements for unauthorized claims.
Can I file a lawsuit over the MedicareCompareUSA data breach?
Possibly. Class-action attorneys are investigating whether negligence contributed to the breach. If eligible, you may seek compensation without paying fees upfront.
What should I do if I notice fraudulent activity?
Immediately file an identity-theft report with the FTC, freeze your credit, dispute any fraudulent charges, and save documentation to support future legal claims.
